The Performance And Application Of Hot Rolled Steel Coil

Aug. 08, 2019

Here is a Galvanized Steel Coil Factory talking about the performance and application of hot rolled steel coil.


The Hot Rolled Steel Coil is made of slab (mainly continuous casting billet), and is heated to be made of strip by rough rolling mill and finishing mill. The hot steel strip from the last rolling mill of the finishing mill is cooled to a set temperature by laminar flow, rolled into a steel coil by a coiler, and the cooled steel coil is subjected to different finishing operations according to different needs of users. Lines (flat, straight, cross-cut or slit, inspection, weighing, packaging and marking) are processed into steel, flat and slit steel strips. Since hot-rolled steel sheet products have high strength, good toughness, easy processing and good weldability, they are widely used in shipbuilding, automobiles, bridges, construction, machinery, pressure vessels and other manufacturing industries.

Conventional process:

The hot-rolled plate unit adopts a modified sendzimir annealing process, and the raw material is hot-rolled pickled coil. The production process is as follows:

Hot-rolled pickling plate roll→Unwinding→cutting head→welding→inlet looper→modified Sendzimir horizontal annealing furnace→hot galvanizing→cooling after plating→zinc layer thickness gauge→lighting tension correction→passivation treatment →Checking table→Electrostatic oiling→Winding→Weighing and packing→ Finished product storage.


With the increasing maturity of new technologies such as hot-rolling dimensional accuracy, plate shape and surface quality, and the advent of new products, hot-rolled steel sheets and strip products have become more and more widely used and are becoming more and more powerful in the market. Competitiveness.
