Roll Surface Treatment Units for Crystallizers

Abstract

The invention relates to a roll surface treatment device for a crystallizer. The roll surface treatment device for the crystallizer comprises a guide rail platform, a sliding board moving in a reciprocating mode along the guide rail platform, a fixed frame comprising a fixed frame body, a supporting arm and a main shaft and a grinding wheel. The front end of the supporting arm is connected with the two ends of the main shaft through bearings and the tail end of the supporting arm is connected with the fixed frame body. The fixed frame body is connected with a sliding board guide rail, so that the fixed frame moves in a reciprocating mode along the sliding board in the direction perpendicular to the crystallizer. The main shaft penetrates through the axis of the grinding wheel, so that the grinding wheel is driven by the main shaft to rotate around the axis and move in a reciprocating mode along the surface of the crystallizer along with the movement of the sliding board, and a fatigue layer on the surface of the crystallizer is removed through friction. According to the roll surface treatment device for the crystallizer, the grinding wheel of the roll surface treatment device moves horizontally on the surface of the crystallizer, the rotation speed is adjusted simultaneously, the direction of the resultant velocity of rotation of the grinding wheel and rotation of the crystallizer is changed continuously, so that multi-angle grinding traces are formed on the roll surface of the crystallizer, the grinding evenness of the roll surface is improved, and therefore the tape manufacturing quality of the crystallizer is improved.

Description

technical field [0001] The invention relates to the technical field of material production equipment, in particular to a roller surface processing device for a crystallizer. Background technique [0002] In the production process of amorphous strips, because it takes a long time, continuously, and high speed to spray molten steel from the nozzle to the high-speed rotating crystallization rolls to produce amorphous strips, the crystallizer roll surface wears rapidly, and we will wear The part is called the fatigue layer. The wear on the mold roll surface will directly affect the quality of the strip. Therefore, it is necessary to process the high-speed rotating crystallizer roll surface in real time during the strip production process to ensure the surface quality. [0003] The usual treatment method is to use the impeller which is parallel to the crystallizer roller and rotates at high speed in the same direction for grinding to improve the surface quality of the crystalli...

AI Technical Summary

Problems solved by technology

Although this method can remove the fatigue layer on the surface of the crystallizer roller and improve the smoothness, the repair marks produced by the grinding wheel on the surface of the crystallizer roller are all in the same direction, and the repair marks will continue to overlap to form deeper mechanical lines.
