Guide guard anti-iron filings clogging type circulation cooling device

Abstract

The invention discloses a circulating cooling device with a guide guard to prevent iron filings from clogging, which includes a guide roller, a temperature control system and a cold water pipe. A cold water pipe is arranged above the guide roller, and the outer wall of the cold water pipe is fixedly connected to the side close to the guide roller. There are a plurality of spouts, one end of the cold water pipe is provided with a water supply pipeline, and the water supply pipeline is connected to a reservoir, the reservoir is located below the guide roller, and the side wall of the reservoir is connected to a water supply pipeline, the A filter net layer is arranged in the reservoir, a limit rod is arranged above the guide roller, a limit guide groove is arranged in the middle section of the limit rod, and guide roller arms are respectively rotatably connected to the two ends of the guide roller. The invention overcomes the defects of the prior art that the cooling automation of the guide roller is not high, and easily causes the clogging phenomenon of iron filings, and provides a temperature control system equipped with shape memory alloy parts.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to a guide and guard anti-iron filings clogging type circulation cooling device. 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 g...
