The invention provides a hot-rolled bar cooling bed. The cooling bed comprises: fixed racks which are fixedly arranged on a straightening plate and comprises fixed long racks and fixed short racks which are arranged in a staggered mode, wherein the fixed long racks extend to an aligning roller way; movable racks which are arranged between the adjacent straightening plates in a reciprocating motion manner and extend to the aligning roller way; a first guide piece which is arranged on the fixed rack and the movable rack in a first selected range on the cooling bed; a second guide piece which is arranged on the movable rack in a second selected range at the aligning roller way; and a third guide piece which is arranged on the fixed long rack in a third selected range at the aligning roller way. According to the invention, the rolled piece can be prevented from being bent by a cooling bed rack in a heat recovery stage, and the situation that the rolled piece cannot be aligned at the aligning roller way due to the dog-foot bend of the rolled piece and the snake bend or curl accident caused by the alignment failure is avoided.
Description
technical field [0001] The invention belongs to the technical field of iron and steel metallurgy, in particular to a cooling bed for hot-rolled bars. Background technique [0002] The cooling bed is a crucial piece of equipment in many process links of the hot-rolled bar production line. Its main function and function is to realize rapid cooling of the rolled piece, alignment of the ends of the rolled piece, arrangement and aggregation, and shearing according to the set count. Output to cold shear for cutting to length. At present, the cooling beds of the bar production lines at home and abroad basically adopt the stepping rack structure. The cooling bed rack is composed of two parts: a fixed rack and a moving rack. The moving rack lifts the rolled piece. With the operation of the cam eccentric mechanism, the rolled piece is moved forward by one tooth pitch and put into the next adjacent one. In the fixed tooth groove, every time a cycle is completed, the rolled piece move...
