Product Details
Ordinary thin steel plates generally use hot-rolled strip steel
with a thickness of 15-6 mm as the cold-rolled return material.
The main processes include pickling, cold rolling, degreasing, annealing, leveling, shearing (cross-cutting, longitudinal cutting), and if the coated plate is produced, there are also plating or coating processes such as electro-tinning, hot-coating tin, hot-coating zinc.
The production process of cold-rolled billet is:
Hot-rolled coils (raw materials) - pickling - cold rolling - degreasing - annealing - skinning - shearing - finished product delivery.
The cold-rolled bad material must go through the continuous pickling unit to remove the scale before rolling, so as to ensure that the surface of the strip is smooth and smooth for cold rolling and subsequent surface treatment.
It can be rolled after pickling, but due to the characteristics of the cold rolling process, it must be annealed to soften the steel after rolling to a certain thickness.
However, during the rolling process, there is lubricating oil on the surface of the strip, and the grease will volatilize in the annealing furnace, and the black spots formed on the surface of the strip by the volatile matter are difficult to remove.
Therefore, before annealing, the grease on the surface of the strip should be cleaned, that is, the degreasing process.
Quality first: production and inspection in strict accordance with production standards;
Price advantage: discounts based on real market prices;
Transaction security: There will be no loss of customer funds;
After-sales guarantee: the customer's problem is our problem;
Long-term cooperation: quality assurance, price advantage, sincere service can last for a long time.

Strict craftsmanship
Cold rolled steel coils generally use hot-rolled strip steel with a thickness of 1.5-6 mm as the cold rolled billet. The main processes include pickling, cold rolling, degreasing, annealing, leveling, and shearing (cross cutting, longitudinal cutting). If producing coated plates, there are also plating or coating processes such as electroplating tin, hot tin coating, and hot zinc coating. The production process of cold rolled billets is as follows: hot rolled sheet coils (raw materials) - acid washing - cold rolling - degreasing - annealing - leveling - shearing - finished product delivery.
