Cold rolled usually adopt the way of longitudinal rolling. Cold rolling production process generally includes raw materials preparation, rolling, degreasing, pickling, annealing (heat treatment), finishing, etc.

Cold-rolled hot-rolled products as raw materials, raw materials before cold rolling of phosphorus removal, to ensure that the surface of the cold-rolled products clean. Is to make the material of rolling deformation of the main process. Skim to remove rolling when attached to the metal rolling lubrication oil, to avoid pollution when annealed steel, also to prevent the increase of carbon for stainless steel. Annealing heat treatment, including intermediate annealing and finished product intermediate annealing is eliminated by recrystallization cold deformation which is caused by work hardening, to resume the plasticity of material and reduce the deformation resistance of the metal.

The purpose of the finished product heat treatment in addition to eliminated by recrystallization hardening. Is that according to the requirements of the product technology in order to obtain required by the organization (such as a variety of texture, etc.) and product performance (e.g., deep drawing, electromagnetic properties, etc.). Finishing includes checking, shear, straightening (flat), printing, sorting, packaging, etc.

Cold rolled products have high requirements, in order to prevent the product surface is scratched in transit. In addition to the above process external production when some special products have their own special processes. Such as rolling silicon steel plate, before the cold rolling for decarburizing annealing, must carry on the coating, high temperature annealing after rolling, stretching tension straightening (see) and tempering, etc.

How to Choose the Right Automotive Steel for Your Vehicle？

There are a few things to consider when choosing the right type of automotive steel for your vehicle. The first is the intended use of the vehicle. If you’re looking for a steel that can withstand high temperatures, then you’ll want to choose a heat-resistant alloy. If you need strong and durable steel, then you’ll want to choose a high-strength alloy. The second consideration is the weight of the vehicle. Lighter steel will be more fuel efficient, while heavier steel will be more durable. The third consideration is the cost of steel. Cheaper steel may not be as strong and durable as more expensive steel, but it may suit your needs. When selecting automotive steel, it is important to consider these factors in order to choose the right type for your vehicle.
