METHOD AND INSTALLATION FOR HOT ROLLING OF BARS IN STECKEL ROLLING MILL

摘要

FIELD: technological processes.;SUBSTANCE: method provides hot rolling of bars in Steckel reverse rolling mill, which has furnace coiler on every side, and withdrawal-roll facility is provided between furnace coiler and Steckel rolling mill. During reverse rolling in Steckel rolling mill bar is cut by means of sole flying end shears, which are installed between withdrawal-roll facility and Steckel rolling mill and arranged in the form of drum-end shears with top and bottom supplied cutting drums, at that, in order to reduce thermal load, both cutting drums are installed during rolling in set-back position with long distance between cutting drum and bar and are brought to cutting position for cutting. In hot rolling installation every cutting drum for reduction of cutting drum is arranged with the possibility of displacement between position that is moved away from bar material and cutting position for cutting.;EFFECT: high-quality cutting of bars without loss of time.;10 cl, 10 dwg
