Compared with prior art, the present invention has following beneficial effect:
The online high-temperature straightening machine of a kind of large-size round steel of the present invention, it does not need to take up space in addition and area, only needs this straightener is arranged in the former organic frame of last one milling train rear end or is arranged at last rolling mill tail region; Can partly carry out on-line straightening to the bar head-bent under the condition of high temperature, solve bar and gone out the milling train occiput and form crooked problem, can be less behind the bar head aligning or not even with cutting away head; Improved lumber recovery, also saved great amount of time and trouble, owing to realized on-line straightening for later process; The back need not be aligned also and can be reached the standard of dispatching from the factory; Make the logistics of whole production link more smooth and easy, avoided the phenomenon of buying and selling back and forth, improved production efficiency; Also having reduced the people is the mixed steel risk that causes, and has reduced workman's burden and pressure.
The smoothing roll group is made up of the V-type smoothing roll of two rows dislocation layout up and down, and the V-type smoothing roll can be controlled the bending that 360 ° of any directions of bar head produce effectively, and eliminates the bending stress of red Steel Bar During head.
When bigger the or red steel flexibility of hot steel and smoothing roll diameter difference was serious, the overload protection cylinder can play a protective role, and prevented down that smoothing roll damages.
Driven axle and driving shaft internal cavities are connected with cooling water pipeline, can prevent that the red steel of high temperature from producing damage to smoothing roll or bearing.
Red generally speaking steel feeding mainly relies on the power of preceding road milling train, rotates but the motor at driving shaft rear and reductor can drive down smoothing roll, thereby plays the effect of assisting feeding.
