The purpose of steel rolling production line is to obtain the required shape, such as steel plates, strip steel, wire rods and various sections, another aspect, in order to improve the internal quality of steel like common automotive plates, bridge steel, boiler steel, pipeline steel, etc. Steel rolling is a continuous and uninterrupted operation. The steel strip runs fast on the roller table with automated equipment bringing high efficiency. Depending on the different temperatures in the rolling method, the steel rolling can be classified into hot rolling and cold rolling. According to the different relationships between the relative movement of the rolling stock and the roll during rolling, it can be divided into vertical rolling, horizontal rolling, and diagonal rolling. In the hot rolling production line, the billet is heated to become soft and is sent into the rolling mill by the roller table, finally rolled to the size required by the users. Compared with hot rolling, the processing line in a cold rolling mill is more scattered. The steel coils sent by the hot rolling mill must undergo three consecutive technical treatments and the oxide film must be removed with hydrochloric acid. Through the cold rolling mill, the uncoiler opens the steel coil and then the steel strip is carried to a five-stand continuous rolling mill to be rolled into a thin strip coil.
50K-300K Ton Bar Production Line
The steel bar production line with the annual capacity of 50K to 300K tons for the production of bars Φ8-32mm of common carbon steel, wire rod steel and low-alloy steel. The production Line uses 100×100–150×150 continuous casting billet, which of length 3000mm–6000mm and provided by the internal steelmaking continuous casting workshop. The annual output of 50,000-300,000 tons requires 330,000 tons of continuous casting billet, and the comprehensive finished product rate is 98% (considering negative deviation). It applies regenerative pusher type reheating furnace of gas fuel, the heating capacity is 40-80t/h. There are sixteen rolling mills divided into three group rolling mills of rough rolling, medium rolling and finishing rolling. The layout type is 6+6+4 H-V rolling mills and their main transmission adopts PLC control.
Φ8~32 Rebar Steel Bar Prodcution Line
The steel rebar production line is used for the production of Φ8-Φ32mm round bar, low-alloy steel and carbon structural steel. It is composed of heating furnace, continuous Rolling mills and cooling bed. The auxiliary equipment includes pinch roller, swinging head scissors, chain type cooling bed, 100 hydraulic metal cutting machine and rolling table. The rebar production line is for sale at TINVO with powerful working team and technology support, best metallurgical design institute and lifelong after-sales & maintenance support.

50K-300K Ton Wire Production Line
The wire production line has the annual production capacity of 50K to 300K tons and can produce welding rod steel, Φ5.5-Φ20mm round bar, bearing steel, etc. The whole line adopts full continuous twistless rolling, and the finishing mill adopts high-precision cantilever rolling mill with high rolling speed, high output, high product precision and high mechanical performance. The main equipment includes rough rolling, pre-finishing rolling mill, finishing mill which is a cantilever type twistless high-speed heavy duty rolling mill, pinch roller, wire laying machine, flying shears, water cooling system, transmission and automation.
