Cold rolled sheet and coil are made of hot rolled coil as raw material, cold rolled at indoor temperature below work hardening temperature, including sheet and coil, which can be produced by many steel mills in China, such as Angang, WISCO, Angang, etc.
In which the sheet supply is called thick steel plate, also known as box plate or tablet computer; Long and short, supply into a plate called steel chain, also known as stainless steel sheet.
The definition of cold binding;
It is cold rolling under work hardening, but it is usually understood that it is cold rolling of raw materials under normal temperature. Aluminum cold rolling is divided into plate rolling and foil rolling. The thickness
of --- ~ or so is called plate, and the thickness of --- ~ or below is called foil
Production process: because heating is not carried out in the processing process, the defects such as black spots and scale often appeared in hot stamping can not
be found, and the process performance is good and the smoothness is high. In addition, the specification of cold rolled products is high precision, and the characteristics and mechanism of products can consider some unique application regulations, such
as electromagnetic induction characteristics, low alloy plate characteristics, etc.
Specification and model: the thickness is 0.3-4mm, the total width is 700-2050mm, and the length of thick steel plate is 1150-65050mm.
carbon steel grade is selected as the key, and it is required to have excellent cold drawing and electric welding characteristics, as well as necessary stamping die characteristics.
Main application: cold rolled steel strip has a wide range of applications,
such as automobile industry, electrical products, locomotives, airlines, hardware and mechanical instrument panel, canned food and fruit, etc.
Cold rolled steel plate is the general name of cold rolled carbon steel plate, also known as cold rolled
steel plate, also known as cold rolled steel plate. Cold rolled steel plate is made of common carbon steel hot rolled strip, which is made into thick steel plate with thickness less than 4mm after deep cold rolling. Because cold rolling at room temperature
does not cause scale, cold rolled steel sheet has good process performance, high precision specifications, and quenching solution, its physical properties and service performance are better than hot rolled steel sheet. In many industries, especially the
household electrical appliances manufacturing industry, it has gradually replaced hot rolled steel sheet.
