circular economy

(I) Vigorously develop circular economy

Tiangang adheres to the development path of circular economy, realizes the efficient utilization of energy and resources, and implements "four closed circuits" for regenerated gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption, vigorously promotes advanced technologies such as new energy-saving technologies, new processes and new materials, and promotes the enterprise's business.

Tiangang has equipped special environmental protection facilities for all pollution sources, which has strengthened the recycling of waste resources and improved the utilization efficiency of resources. At present, the recycling rate of solid wastes such as iron slag, steel slag, iron-containing dust sludge, steel rolling scale and environmental protection dust has reached 1%. Power boilers, heating furnaces of double bars, double high-speed wires and medium plates all adopt heat storage technology, which can completely use blast furnace gas; Steel ladle baking, Maierzi active lime kiln and medium plate heat treatment heating furnace all burn converter gas, which improves the utilization rate of secondary energy. The steelmaking process realizes negative energy steelmaking. Through the utilization of blast furnace gas residual pressure power generation (TRT) project and low-pressure waste heat steam power generation projects such as converter and sintering, the residual energy and waste heat are fully utilized. The reuse rate of production water is 98% by using the methods of clear and turbid water diversion, multi-purpose, cascade use and recycling.

(II) The benefits of energy saving and emission reduction are obvious

Tiangang has focused on the enterprise energy saving and emission reduction targets proposed by the municipal government, fully exerted the advantages of circular economy formed after the eastward movement was fully completed and put into operation, and vigorously promoted the implementation of energy saving targets. Through measures such as tapping the potential of energy conservation, technological innovation, and strengthening management, the energy-saving target of 7% annual decrease in energy consumption and added value determined in the "Eleventh Five-Year Plan" and "Energy Saving Target Responsibility Letter" signed with the municipal government has been exceeded for three consecutive years. It has made a great contribution to the energy saving in Tianjin. Tianjin Steel Pipe Group Co., Ltd., also known as "Tianjin Great Seamless", is located in Tianjin Binhai New Area and is the steel pipe base of China energy industry. Construction started in 1989, the hot test was successful in 1992, and it was officially put into production in 1996. The main products are oil casing, oil pipe and pipeline pipe, high-pressure boiler tube, high-pressure gas cylinder pipe, hydraulic support pipe and other professional pipes. At the beginning of its establishment, the company introduced the world's most advanced equipment technology of steelmaking, pipe rolling, pipe processing and direct reduction iron from Germany, Italy, the United States and Britain, and equipped with a perfect automation system, becoming the most advanced and largest professional oil pipe manufacturer in China. Since it was put into production, it has always maintained the leading edge of technical equipment through continuous technical transformation.

Tianjin Steel Pipe Group Co., Ltd. is the largest oil casing production base in China at present, commonly known as "Great Seamless" in Tianjin. This project is a national key project during the Eighth Five-Year Plan. Ground was broken in 1989, hot test was successful in 1992, and it was officially put into production in 1996. The original design was to produce 6, tons of billet and 5, tons of seamless steel pipe, including 35, tons of oil casing. The main products are high and medium pressure boiler tubes, high pressure gas cylinder tubes, hydraulic support tubes, pipeline tubes and other special pipes. After more than ten years of hard work, it ranks among the forefront of large seamless steel pipe enterprises in the world, rewriting the history of China's long-term dependence on imports of oil casings and becoming the main force in China's international competition.
