Question 5: What are production technology, production technology, and production process? What is the difference between these three? I personally think this is the difference. I hope it will be helpful to you.

Production technology: It is mainly a special plan compiled by the manufacturing industry in order to coordinate the rational use of effective resources and various related production technologies and focus on technical aspects to ensure that it can better play a good guiding role in the production process.

Produce Craft is a method and process in which workers use production tools to perform value-added processing or processing of various raw materials and semi-finished products, and finally turn them into finished products.

Production process (Technological process): a program that arranges various processes from raw materials to finished products. It consists of two or more business steps to complete a complete business behavior process, which can be called Process; note that it is two or more business steps.

Question 6: What are the raw materials and production processes of steel? The source of steel is iron ore, which is the form in which iron element (Fe) exists in nature. Pure iron does not exist in nature. , Iron ore is mainly divided into three types: magnetite, hematite, and limonite. These are all oxides of iron. The difference lies in their oxidation method. The higher the iron content in iron ore, the better. Theoretically, the highest iron content in iron ore is about 72%, and iron content above 60% is called rich iron ore. The iron ore is first reduced to iron (milled iron) in the furnace, and then sent to the steel-making furnace for decarburization and refinement into steel. Scrap steel can also be smelted and regenerated in the steel-making furnace. Generally, steel is made into products with different properties and shapes depending on the intended use, which are so-called steel products. Usually iron ore is reduced and melted into milled iron (milling). The milled iron is refined into steel (steelmaking). The steel is then rolled and processed to make various steel products. In a broad sense, steel products include cast iron, Cast steel, forged steel products and steel processed products. Before discussing the raw materials of steel, we must first clarify what is the difference between steel and iron? Are there different ingredients? In daily life, everyone always calls steel and iron together as "steel". It can be seen that steel and iron should be the same substance; in fact, from a scientific perspective, steel and iron are slightly different. , their main components are iron, but the amount of carbon they contain is different. We usually call anything with a carbon content above 2% "pig iron", and anything below this value is called "steel". Therefore, in the process of smelting steel, iron-containing ore is first smelted into molten pig iron in a blast furnace (blast furnace), and then the molten pig iron is then refined into steel in a steel making furnace. The raw materials required for the production of steel are divided into four major categories to discuss respectively: the first category discusses various iron-containing ore raw materials; the second category is coal and coke; the third category discusses the manufacturing processes used in the smelting process. The flux (or flux) of slag (sl*g), such as limestone, etc.; the last category is various auxiliary raw materials, such as scrap steel, oxygen, etc. 2. Types and Distribution of Iron Ore In theory, any ore containing iron elements or iron compounds can be called iron ore. However, in terms of industry or commerce, iron ore must not only contain iron content, but also must have utilization value.

However, since it is difficult to absolutely determine whether an ore has utilization value, it is difficult to establish a standard for iron ore in the industry. For example, the iron ore produced in Europe is of poor quality and has very low iron content. Just because they can't find good ore, they call this ore iron ore; while Australia currently has good quality because of its high quality. There are plentiful stocks of ores with high iron content, so ores like those used in Europe have been considered worthless in Australia. Then, the iron ore used in Europe is not considered iron ore by the steel industry in the United States. For another example, in the past, ores that were considered to have too low iron content were of no use value. Due to the advancement of industrial technology, many cheap methods have been developed to enrich the iron content in the ores. Therefore, these ores with low iron content have become Become valuable iron ore. Therefore, we came to the conclusion that the industrial standards for determining iron ore change with regional supply and demand relationships, changes in industrial technology levels, and transportation conditions. According to current standards, the average iron content in the ore is about 25% or more before it can be called valuable iron ore. Iron exists in nature in the form of compounds, especially in the form of iron oxide in large amounts. Now let’s take a look at some of the more important iron ores: (The first three are the main types) (1) Magnetite is an iron oxide ore whose main component is Fe3O4, which is a composite of Fe2O3 and FeO. It is black-gray in color, has a specific gravity of about 5.15, contains 72.4% Fe, 27.6% O, and is magnetic. Magnetic separation can be used during beneficiation, which is very convenient to handle; however, due to its fine structure, it has poor reducibility. After long-term weathering, it turns into hematite. (2) Hematite is also an iron oxide ore. Its main component is Fe2O3. It is dark red in color and has a specific gravity of about 5.26. It contains 70% Fe and 30% O. It is the most important iron ore. It can be divided into many categories according to its different structural conditions, such as red hematite, specularhematite, mica iron ore (...>>

Question Seven: In the process design, what are the steps determined by the production method and the process? The production method and the process are two concepts. The process is the entire production process of a product from beginning to end, and the production method is the specific operating method and sequence. (Such as starting and stopping water pumps, fans, compressors, etc., feeding a reactor, stirring to heat up, and cooling down to produce products)

Question 8: What are the main processes of casting? The casting production process is a complex and comprehensive combination of processes, which includes many production processes and links, from the preparation of metallic materials and non-metallic materials to alloy smelting, molding, core making, and mold casting. , cleaning, casting defect elimination and heat treatment to obtain qualified castings. The casting production process includes the following main processes:

1. Preparation of molding sand and core sand. The preparation process of molding sand directly affects the quality of molding sand. The preparation of molding sand Generally divided into the preparation and inspection of raw materials and the preparation and quality control of molding sand

2. The method and process of making sand molds with molding sand and pattern and other process equipment is called molding. There are many types of molding methods, which depend on it. Depending on the shape, size, and technical requirements of the casting, etc.

3. Smelting changes the metal from solid to liquid through heating, and removes impurities in the molten metal through metallurgical reactions to make its temperature and composition meet the requirements. The required process and operation are called smelting. There are many types of equipment for smelting metal. We produce cast iron platforms, and cupola furnaces are generally used for machine tool castings.

4. Sand mold drying is suitable for some larger or high-quality castings. Dry pouring is generally used, such as large cast iron flatbeds, machine tool bed castings, machine tool worktables, machine tool castings, etc.

5. Pouring The operation of pouring molten metal into the mold from the pouring ladle is called pouring.

6. The process of removing surface adhering sand, molding sand and excess metal from the casting after cleaning the shakeout is called cleaning

7. Casting heat treatment heats the casting to a certain temperature range The process of keeping heat for a period of time and then cooling it to the appropriate temperature at a specified speed to obtain the expected structure and performance is called casting heat treatment. The purpose of heat treatment of castings is to eliminate the casting stress of castings, such as cast iron platforms and machine tool castings. , the machine tool table must be heat treated before processing.

Question 9: What does process management include? Process management is an integral part of technical management and is the core of technical management. It reflects the company's production policy. --The guarantee of high quality, high output, low consumption and high efficiency is one of the standards for measuring the level of enterprise management. 1. Responsible for not completing the process preparation work within the time limit specified in the plan, which affects the progress of new product trial production and the completion of production tasks. . 2. Responsible for economic losses caused by a large number of products being scrapped or repaired due to process preparation or tooling design problems. 3.

Question 10: What are the classifications of non-woven fabrics based on production processes? According to different production processes, non-woven fabrics can be divided into:

Spunlaced non-woven fabrics: Spunlaced non-woven fabrics spray high-pressure fine water onto one or more layers of fiber webs to entangle the fibers with each other. The fiber mesh is reinforced and has a certain strength.

Heat-sealed non-woven fabric: refers to adding fibrous or powdery hot-melt adhesive reinforcement materials to the fiber web, and then the fiber web is heated, melted and cooled to strengthen it into a cloth.

Pulp air-laid non-woven fabric: also known as dust-free paper and dry paper-making non-woven fabric. It uses air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-flow method to agglomerate the fibers on the web curtain, and then strengthen the fiber web to form cloth.

Wet-laid non-woven fabric: The fiber raw materials placed in the water medium are opened into single fibers, and different fiber raw materials are mixed at the same time to form a fiber suspension slurry, which is transported to the web-forming mechanism. The fibers are formed into a web in a wet state and then reinforced into cloth.

Spunbond non-woven fabric: After the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then bonded by itself, thermally bonded, chemically Bonding or mechanical reinforcement method to turn the fiber web into a non-woven fabric.

Melt-blown non-woven fabric: Its process: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- web forming --- reinforcement into cloth.

Needle-punched non-woven fabric: It is a type of dry-laid non-woven fabric. Needle-punched non-woven fabric uses the puncture effect of needles to reinforce the fluffy fiber web into cloth.

Stitch-bonded non-woven fabric: It is a type of dry-laid non-woven fabric. The stitch-bonded method uses a warp-knitted loop structure to reinforce the fiber web, yarn layer, non-woven material or their combination. , to make non-woven fabrics.
