Part 2 Processflow introduction
Part 3 Units equipment level and its characteristics
The main technology of hot continuous rolled bar production line equipment:
l Full continuous rolled, less accidents, easy operation and maintenance;
l The automation control system is perfect to ensure the high output, high efficiency, low cost and high quality of the rolling mill.
l The rolled speed is high and the mill productivity is high;
l The rolled mill adopts POMINI short-stress line rolled mill to ensure high-speed rolled and split rolled;
l The unit is arranged alternately to realize the torsional rolled, the coarse and medium rolled micro tension rolled, and the finishing rolled without tension rolled, which can ensure the high precision of the product;
l Finishing mill is equipped with water-cooling device before and after, which can produce Grade III threaded steel bars;
l The rolled mill adopts a hydraulic traverse device, which is convenient for quick replacement of the roll hole type;
l The rolled mill unit adopts the integral rack quick change device, which can greatly improve the production operation time;
The rack-type cooling bed is used, the rolled parts are cooled evenly, and the rolled parts have straightening effect;
