Kaiping in steel is a colloquial name. When steel plates come out of the steel mill, they are rolled. The flat plate after these steel plates are opened by the machine is called "open flat plate".

Steel plate is a flat steel which is cast, cooled and pressed by molten steel. It is a flat rectangle and can be directly rolled or cut from a wide steel strip. Steel plates are divided by thickness, and thin steel plates

The internal stress distribution of the plate varies with the process parameters during the operation of the plate, and the bearing capacity will be different in different directions of the vertical length. Moreover, this bearing capacity is difficult to be measured by general strength indicators. Therefore, there will be great welding deformation when welding flat plates, which is difficult to adjust. Therefore, the flat plate cannot be used for parts that require high appearance quality.

Kaiping plate and original flat plate should be called shear steel plate and single rolled steel plate respectively.

Extended data

The difference between Kaiping board and original flat board:

1, generally speaking, continuous rolled steel plate has thin specifications, narrow width and high tolerance zone;

2. The roughness of continuous rolled steel plate is obviously worse than that of single rolled steel plate;

3. Different cutting methods: the original flat plate is generally cut on four sides, and the open flat plate is generally cut on two sides;

4. The flat plate is made of strip steel after uncoiling, leveling and shearing, and its mechanical properties are not as good as the original flat plate;

5. The original unit price is higher than the public unit price;
