All of us at the time of purchase some roller products, attaches great importance to the quality of the products, to buy good quality casting roller, can guarantee the quality of our products, and there are many factors that can affect the quality of our continuous casting roller, the casting roll material impact on the quality of our entire product is very big, this way we will learn about the casting roll material knowledge, hope everyone at the time of custom continuous casting roller, can buy a better quality of continuous casting roller, to ensure production use effect.
The requirements for continuous casting roll material should be high yield strength at high temperature, good resistance to high temperature oxidation, and high resistance to high temperature fatigue crack formation and expansion. In the past, ordinary carbon steel, low-alloy steel and 1Cr1 and other materials were used for continuous casting rollers. With the development of production, the frequent replacement of rollers could not meet the production requirements, so in recent years, 1Crl3MoV materials were mostly used. High yield strength at high temperature. Therefore, it has high resistance to high temperature deformation under the working conditions of continuous casting. Higher yield strength is found up to 750℃. High temperature oxidation resistance, so it has a good oxidation resistance in the high temperature and humid environment of continuous casting production, that is, it has a good abrasion resistance. Strong ability to resist heat crack formation and propagation. Thermal fatigue is less likely to result in crack initiation and propagation leading to fracture.
Material is one of the most important factors to influence us these continuous casting roller, and we produce the processing technology of continuous casting roller, only this, to guarantee the two can ensure the quality of our continuous casting roller, is not only the continuous casting roller, our mist side roller, too, at the time of production must be pay attention to the material and production process requirements, only in this way, can we guarantee continuous casting roller production quality, in our industrial production play a greater role in the process.
