Hot Rolled Strip

Description of Hot Rolled Steel Strip
Hot Rolled Steel Strip generally refers to a coiled steel strip having a
thickness of 1 to 20 mm, and the width is generally 600 to 2000 mm. The hot
rolled steel strip can be used directly as a hot rolled steel sheet, or a cold
rolled strip can be supplied as a billet. Widely used in automotive,
electrical, chemical, shipbuilding, and other industrial sectors, but also as a
billet for cold rolled, welded pipe, cold-formed steel production. Strip hot
strip mill is the main equipment for producing hot rolled steel strip, which
has the advantages of high production efficiency, high output, and good
quality.

Production Procedure of Hot Rolled Steel Strip
The slab is the first production material of the rolling of hot rolled steel
strip and the surface cleaning can be manually or by a scarfing machine with
running the oxyacetylene torch. The treatment of the slab is pushed or walked
over the wide side through a heating furnace with a dimension of 13 meters by
30 meters in diameter. These furnaces have the advantage of not creating cold
streaks and slippage on the slab. As with flat and thick plates, the preheating
temperature is approximately 1,250°C. After roughing, when needed for
metallurgical reasons, it goes into the long (about 140 m) roll in front of the
finishing mill for cooling. When the slab (at a speed of about 20 meters per
minute) enters the finishing mill line, crop shear cuts off the head and tail,
and high-pressure steam jets remove the secondary oxide coating formed during
the rolling process. The strip is then rolled to a final thickness of 1.5 to 10
mm by six to seven high finishing mill stands.

Application of Hot Rolled Steel Strip
There are four ways for hot rolled steel strip according to product width and
production process: hot strip rolling of wide strip steel, reversible hot
rolling of wide strip steel, hot strip rolling of narrow strip steel and hot
strip rolling with a planetary rolling mill. The strip steel is made of plain
carbon steel, low alloy steel, stainless steel, and silicon steel. Hot rolled
steel strip is mainly used for raw materials of cold rolled strip, welded pipe,
cold-formed and welded steel or for making various components.
