It is a product obtained by cold-pressing a hot-rolled sheet. Due to the multi-pass cold rolling, the surface quality is better than that of the hot-rolled sheet, and after the heat treatment, good mechanical properties can be obtained.

When the output of cold-rolled wear-resistant plates is more than 1 million tons/year, modern cold-rolling units with large-scale, continuous, automatic and high-speed characteristics should be adopted. To improve production efficiency, try to avoid multiple single or double machines works following reversible rolling method.

All steel plate and pipe products contains 2 basic elements- carbon and iron, there might be some composition differences and various manufacture process. As for galvanized steel coil and cold rolled steel coil, they are similar steel products with unique performance and applications.

Alloy and composite cold-rolled steel plate knowledge. It is made of zinc and other metals such as lead and zinc to make alloys and even composite plated steel sheets. This kind of steel plate has both excellent anti-rust properties and good coating properties.

Distribution transformer is an important electrical equipment in the power system. Its main function is to convert the high voltage on the transmissio

Dry-type transformer manufacturers believe that dry-type transformers refer to transformers whose core and windings are not immersed in insulating oil.

Resonant Transformer is a special type of transformer that is mainly used in high-frequency circuits, especially in applications such as resonant circuits and inverters.

Galvanized steel plates are divided into ordinary electrolytic plates and fingerprint-resistant electrolytic plates.

Cold rolling is made from hot-rolled coils as raw materials, which are rolled at room temperature and below the recrystallization temperature.
