Technical Field

[0002] Strip steel is a thin and wide flat steel made by hot rolling or cold rolling. Its thickness is usually between 0.1mm and 6mm, and its width can reach more than 2000mm. It is supplied in coil or plate form. As an important basic material for modern industry, strip steel combines high strength with good formability and is widely used in automobile manufacturing (body panels), home appliances (housing), construction (roof / curtain wall), packaging (steel containers) and other fields. Its production involves processes such as precision rolling, heat treatment and surface treatment. By adjusting the composition (such as low carbon steel, high strength steel, stainless steel) and process parameters (such as annealing, galvanizing), different mechanical properties and surface characteristics can be obtained to meet diverse industrial needs. The efficient and continuous production of strip steel makes it one of the core raw materials for large-scale manufacturing.

The heat treatment station includes a strip steel heating section, a strip steel quenching section, and a strip steel constant speed section arranged in sequence. The strip steel heating section is close to the strip steel loading station, and the strip steel constant speed section is close to the strip steel receiving station. The utility model completes the heat treatment of sorbite steel strip in an automated and production-line manner, achieves strict control of the heat treatment process of the steel strip, avoids the processing errors existing in manual operation and station-based operation in the existing technology, effectively improves processing accuracy, ensures the standardization of the heat treatment process, and guarantees the final yield rate of the sorbite steel strip product;
