Description
Technical Field
The utility model belongs to the technical field of the metallurgical continuous casting direct rolling technique and specifically relates to a bar wire rod directly rolls roll table.
Background
The steel rolling of the elevated platform is different from the traditional ground arrangement mode, and has the unique advantages that: firstly, the arrangement is compact, neat and concise; secondly, underground engineering can be reduced, and great flexibility is achieved; thirdly, various interrelations are simple and clear.
Because the elevation of the billet discharging plane (plus or minus 0m) of the continuous casting machine is inconsistent with the elevation platform of the rolling line elevation, a steel billet is usually lifted to the platform by a lifter or a trolley, and the lifting mechanism has a complex structure, is slow in rhythm and consumes time and labor.
If direct rolling is adopted, the method not only saves energy, has high speed and high yield, but also has small blank deformation. When a billet rises along a certain angle on a straight rolling roller way, the climbing height is too large, the roller is smooth, the roller way rotates fast, and the phenomenon of slipping is easy to occur; too small gradient requires too long roller way, too much heat loss, and the straight rolling temperature cannot be ensured. In addition, the billet also has a length, and if the angle of the initial section is directly changed to an angle, the rolled piece will impact the roller way, and the rolled piece of the last section will empty and collide with the roller way when falling.
