Cold rolling and hot rolling processes are two methods of forming steel. Cold rolled products have a higher degree of product dimensional accuracy and are suitable for applications with high dimensional requirements.

A steel coil is a flat sheet of metal that has been rolled or coiled to a width much greater than its thickness. Steel coils are used in a variety of

Cold rolled steel is generally used to describe a range of finishing processes, but technically speaking, cold rolling is only applicable to extruded steel plates between rolls. If the rod or tube pull out of the steel die should be pulled out, not rolled. Other cold finishing processes include turning, grinding and polishing for converting existing hot-rolled billets into a better product.

A steel grade is a chemistry that has been processed in a certain way and to meet certain requirements. There are a number of different grading systems that can be used to identify steel grades, such as ASTM, SAE, JIS, EN, and more.

Cold rolled steel starts with large billets or staves cast from hot liquid metal, then the billets are heated to eventually reach over 1700°F. At this high temperature, they are easily flattened into long sheets with a set of rolls and then rolled into large coils.

Both cold rolled steel and hot rolled steel are types of steel commonly used in the manufacture of various products.

The steel sheert is the product after the steel coil is cut, and the steel strip is the product after the steel coil is decoiler. If the width of the coil is more than 60 cm, it is a coil, and if it is less than or equal to this width, it is a strip. Theoretically, they are a product, but the form of expression is different.(As shown above)

A power transformer is a static electrical device that is used to convert a certain value of AC voltage (current) into another or several different va

Oil-immersed transformers usually use three cooling methods: oil-immersed self-cooling, oil-immersed air-cooling and forced oil circulation.
