Abstract

The invention discloses a steel plate cold rolling and coating integral production set and production technology, and relates to the field of steel plate cold rolling and coating. The production set comprises a cold rolling system, and the cold rolling system comprises a raw material preparation device, a rolling mill, a degreasing device, an annealing reduction device, a cooling device and a finishing device. The cooing device comprises an air cooling device and a water cooling device. The raw material preparation device comprises an uncoiler, and a first straightener, an inlet scissor, a welding machine and an inlet loop which are sequentially arranged at one side of the uncoiler, the rolling mill and the degreasing device are sequentially arranged a the other side of the uncoiler, the cooling device and the finishing device are sequentially arranged at one side of the inlet loop far from the welding machine, and the finishing device comprises a second straightener, a passivation coating machine, a cutting scissor, a coiler and an outlet loop which are sequentially arranged. The coating system is arranged between the inlet loop and the cooling device, and is used for coating steel plates processed by the annealing reduction device and conveying the processed steel plates to the cooling device. The production set and the production technology have the advantages of reduction of the fixed investment and raw material cost, profit increase, and improvement of the quality of coated products.

Description

technical field [0001] The invention relates to the field of steel plate cold rolling coating, in particular to a steel plate cold rolling coating integrated production unit and a production process thereof. Background technique [0002] In recent years, with the vigorous development of modern industry, construction, and household appliances, the demand for cold-rolled steel products is increasing. Because cold-rolled steel has good surface quality and high dimensional accuracy. The performance and process performance are superior to hot-rolled steel sheets. In many fields, especially in the field of home appliance manufacturing, it has been gradually used to replace hot-rolled steel sheets. After the cold-rolled steel sheet is obtained, the required sheets such as galvanized sheet, aluminum-zinc sheet or zinc-aluminum sheet can be obtained through the coating process. [0003] At present, the production process of cold rolling line of steel plate and coating line of steel ...
