Fast cooling and lubricating scale removal guide and guard system

Abstract

The invention discloses a fast cooling and lubricating scale removal guide and guard system. The fast cooling and lubricating scale removal guide and guard system comprises a left guide roller arm and a right guide roller arm, and is characterized in that a guide roller is rotationally mounted between the left guide roller arm and the right guide roller arm; a limiting rod is arranged on one side of the guide roller; a wire lower scale removal dredging groove is formed in the center section of the limiting rod; an upper scale removal dredging groove is formed above the wire lower scale removal dredging groove; the side wall of the upper scale removal dredging groove is connected with an air cylinder through a connecting rod; the upper scale removal dredging groove can be opened and closed up and down through adjustment of the air cylinder; an oil storage box is arranged on the side wall of the upper scale removal dredging groove and communicates with a lubricating oil channel on the inner wall of the upper scale removal dredging groove; the oil storage box communicates with an outer pump body; a cold water pipe is arranged on one side of the guide roller; and the two ends of the guide roller are rotationally connected with the guide roller arms correspondingly. According to the fast cooling and lubricating scale removal guide and guard system, the defect that the guide roller cooling automation degree in the prior art is not high is overcome; the scale removal effect is good; a temperature control system provided with a shape memory alloy part is provided; and the beneficial effects of being high in automation degree, saving water and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to a rapid cooling lubricating descaling guide system. Background technique [0002] The guide rollers on the existing guides work for a long time, due to contact and friction with the steel rolling, the phenomenon of heat generation of the guide rollers is serious, because the hardness and wear resistance of the metal at high temperatures are reduced, so the guide rollers at high temperatures and the steel rolling Continued contact friction will further accelerate the wear of the guide roller and reduce the service life of the guide roller. In the prior art, the method of spraying cold water on the guide roller is often used to cool it down. For example, patents 2016212308840 and 2016211875641 spray cold water through the guide roller through the pipeline This way of cooling is not highly automated, it cannot detect the real-time temperature of the guide rollers, and it is ea...
