Cold rolling is usually carried out by means of longitudinal rolling. Common products include cold-rolled steel sheets and Cold Rolled Steel Coil. The cold rolling production process generally includes raw material preparation, pickling, rolling, degreasing, annealing (heat treatment), finishing.
Coating Galvanized Steel Strip is not unfamiliar to everyone, but many owners do not know what is hot-plated and what is cold-rolled. In fact, the materials used in the two steel plates are the same, but they are changed into two different plates through different processing methods.
A Coating Galvanized Steel Strip is a steel sheet whose surface is coated with a layer of zinc. Galvanizing is a cost-effective and effective rust-preventing method that is used in the world for about half of the world's zinc production.
Galvanized Steel Sheet are classified into ordinary electrolytic plates and fingerprint resistant electrolytic plates. The anti-fingerprint board is based on the addition of an ordinary electrolytic board to a fingerprint-resistant treatment, which is resistant to sweat.
Cold rolling and hot rolling are two ways of rolling steel. Cold rolling and hot rolling are two different steel rolling technologies. As the name suggests, cold rolling is done in steel at normal temperature. The hardness of this steel is large.
In the daily life of automotive manufacturing, electrical products, rolling stock, aviation, precision instruments and mechanical parts and other products need to use cold-rolled steel or hot-rolled steel, then what is the difference between the two?
Galvanized coils are widely used in construction, chemical, electronics, military and other industries.
Galvanized Steel Coil Factory would like to analyze the difference between rolled steel and flat steel. Sheet bending is a type of steel sheet that is actually a long thin steel sheet that is supplied in rolls.
The Cold Rolled Steel Sheet is made of hot-rolled steel coil. It is first subjected to pickling treatment to remove the oxidized outer skin, and then subjected to cold rolling treatment.
From the development of the main demand industry, China's Galvanized Steel Coil is not only domestically demanding, but also export a large number of products to other parts of the world every year.
