Method for controlling rotation of continuous casting deburring machine

Abstract

The invention discloses a method for controlling rotation of a casting blank deburring machine. The method includes that in the step of removing burrs on the lower edge of the head of a casting blank, a deburring roller on the head of the casting blank rotates in the direction opposite to the moving direction of the casting blank, and in the step of removing burrs on the lower edge of the tail portion of the casting blank, a deburring roller on the tail portion of the casting blank rotates in the direction the same as the moving direction of the casting blank. According to the method, the qualified rate of the casting blank is greatly improved, steel production quality is improved, labor maintenance amount can be reduced, and production expenses are reduced.

Description

technical field [0001] The invention belongs to the process technology of steelmaking, rolling and continuous casting, and in particular relates to a method for controlling the rotation of the deburring machine during the process of removing the burrs of the billet by using the deburring machine. Background technique [0002] The billet burrs left after the flame cutting of the end of the hot billet in the steelmaking or rolling mill are also called steel slugs. [0003] At present, in the production process of steelmaking and continuous casting, the control flow of the hammer knife rotation when using the hammer knife deburring machine to remove the billet burrs is as follows: [0004] 1) The deburring steps of the lower edge of the slab head: when the slab head passes the deburring machine, the detection device sends a start signal, so that the deburring machine with the deburring roller is lifted by the hydraulic cylinder to a predetermined height and starts clockwise Ro...

AI Technical Summary

Problems solved by technology

[0006] In the process of deburring the above-mentioned billet, due to the difference in the characteristics of the steel grades produced, the billet burrs of some steel grades will stick together; moreover, the high-speed rotation of the deburring machine makes the deburring roller drive the burrs to the billet The position of the head and tail end faces cannot fall off, such as figure 1 As shown; some steel mills specially set up a maintenance process for this purpose, and manually remove the burrs formed on the end face of the billet head and tail; while some steel mills do not take any measures to deal with this, which makes the removal of the billet burrs unclean And reduce the success rate of cast slab, resulting in the decline of steel production quality
