The section rolling mill consists of a 2-hi reversing preliminary rolling frame, a reversible series frameset consisting of a universal working rolling frame and a flange rolling frame, and a universal finishing stands arranged on the discharge side. The reversible series frame group 16 disposed behind the reversible rolling stand 1 is composed of a universal work frame 4, a flange rolling frame 15 and a universal finishing stand 8. The dimensional accuracy and surface quality of the rolled material are not affected after long-term use of the rolling mill, provided that the reduction ratio of the universal finishing stand 8 is less than the reduction ratio of the universal working frame.
The production line of hot-rolled products for the I-beam, angle, channel and bar, the main process is: after steel scrap smelting, cast into billets by a continuous casting machine, the conveyor roller through hot rolling back and forth fed into roughing train after N passes into the rolling unit for precise molded; finished steel after hot rolling into the cooling bed for cooling and straightening, cutting, stacking, packaging, weighing, storage.
Section Rolling Mill/Structure Rolling Mill Production Line
Raw material: Scrap, billets, ingot
Finished products: Angle steel, Channel steel, I-beam, Steel sheet, flat steel, round bar, square bar etc.
Annual capacity: 30,000 tons Up to 500,000tons
1. Most of the small-sized steel section rolling mill production line adopts the continuous rolling process, which can ensure that the rolling speed of each track increases proportionally with the elongation coefficient of the tie-in, and achieves high-speed rolling during low-speed biting and finishing rolling in rough rolling;
2. The temperature drop is small, which ensures the required rolling speed, because reciprocating rolling and traverse are avoided during continuous rolling, saving time;
3. It is beneficial to the rolling of thin and thin steel, the improvement of the quality of small products and products;
4. It is beneficial to continuous casting billet, reduce cost and save energy, reduce bite accident and other equipment accidents, improve operating rate, reduce rolling load, save power consumption, roller consumption, reduce equipment accidents, and improve the quality of the rolled parts, while liberating the labor force.
