Description

Continuous casting square billet crystallizer foot roller opening degree adjusting device

Technical Field

The utility model belongs to the technical field of metallurgical industry equipment, a continuous casting square billet crystallizer foot roll opening degree adjusting device is related to.

Background

A set of foot roller device is arranged at the bottom of the copper pipe of the square billet continuous casting crystallizer. The foot roller device consists of a foot roller frame, eight sets of roller sets and 16 sets of adjusting devices, wherein the distance between the inner arc foot roller and the outer arc foot roller is 244mm, the distance between the north arc foot roller and the south arc foot roller is 242mm, and the error is 0-0.2 mm. The traditional method for adjusting the opening degree of the foot roller is to install a bearing seat and adjust the opening degree of the crystallizer by adjusting the position of the bearing seat. The electric stirring of the crystallizer is added after the upgrading and reconstruction of the casting machine, the diameter of an inner circle of the electric stirring of the crystallizer is only 600mm, and the maximum diameter of the outline dimension of a foot roller of the crystallizer is smaller than 600mm due to the increase of the electric stirring of the crystallizer. The technical problem to be solved is how to satisfy the conditions of process requirements under the conditions of reducing the space, ensuring that the foot roller has enough strength and keeping the original roller structure unchanged.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a sufficient roller opening degree adjusting device of continuous casting square billet crystallizer, this kind of device occupation space is little, can improve the operating efficiency at the sufficient roller opening degree of crystallizer repair in-process quick adjustment, shortens crystallizer repair cycle when guaranteeing sufficient roller opening degree adjustment accuracy.

The technical scheme for solving the technical problems is as follows:

the continuous casting square billet crystallizer foot roller opening degree adjusting device consists of two sets of adjusting mechanisms, wherein the two sets of adjusting mechanisms are arranged between a foot roller shaft and a foot roller frame, and each set of adjusting mechanism comprises an adjusting plate, a fastening bolt, a lifting screw rod and a shaft fixing bolt; the adjusting plate is an L-shaped structural steel plate, a foot roller shaft hole is formed in the L-shaped long edge of the adjusting plate, and a shaft fixing bolt is arranged on the side face of the foot roller shaft hole; the L-shaped short edge of the adjusting plate is provided with a lifting screw and a fastening bolt; the foot roll shaft hole on the long edge of the L shape of the adjusting plate is matched with the foot roll shaft and fixed through a fastening bolt, and the foot roll shaft hole and the foot roll shaft are assembled and fixed through a shaft fixing bolt.

The utility model discloses a L type adjusting plate has reduced the volume of equipment greatly, and the equilibrium of sufficient roller structure has been guaranteed to the regulating plate that exists in pairs. The adjusting plate is placed between the foot roller frame and the foot roller shaft, the shaft hole of the L-shaped long side of the adjusting plate is matched with the shaft and fixed through the fastening screw rod, and the opening degree of the foot roller of the crystallizer can meet the requirement by adjusting the lifting screw rod of the L-shaped short side of the adjusting plate. And finally, detecting and adjusting data by using the feeler gauge and the inside micrometer, and fastening the fastening bolt on the short edge of the adjusting plate after the feeler gauge and the inside micrometer are correct. Therefore, the beneficial effects of the utility model are that solve the interior opening degree adjustment difficult problem of crystallizer foot roller little space, solved the problem that maintenance duration is long, inefficiency simultaneously, can repair the in-process quick adjustment foot roller opening degree at the crystallizer, the operating efficiency improves more than 10 times, can shorten crystallizer repair cycle when guaranteeing foot roller opening degree adjustment accuracy, has apparent progress effect.
