| 冷轧是指在常温下，经过冷拉、冷弯、冷拔等冷加工把钢板或钢带加工成各种型式的钢材。 Cold rolling refers to cold drawing, cold bending, cold drawing and other cold processing to process steel plates or strips into various types of steel at room temperature. 优点： 成型速度快、产量高，且不损伤涂层，可以做成多种多样的截面形式，以适应使用条件的需要；冷轧可以使钢材产生很大的塑性变形，从而提高了钢材的屈服点。 Advantages: rapid forming speed, high output, and no damage to the coating, can be made into a variety of cross-section forms to meet the needs of the use conditions; cold rolling can make the steel produce great plastic deformation, thus improving the yield point of the steel. |
