Product Details

The continuous casting roll sleeve is a core component of the continuous casting machine roller. It is usually installed on the outside of the roller shaft and directly contacts the high-temperature cast billet, undertaking key functions such as support, guidance, and heat transfer.

The working environment of the continuous casting roll sleeve is extremely harsh. It must not only withstand the high temperature and thermal stress transmitted by the cast billet, but also maintain high precision and wear resistance during high-speed operation to ensure the quality and dimensional accuracy of the cast billet surface. Its material is mostly high-alloy steel or special heat-resistant alloys, made through multiple processes such as precision casting, heat treatment, and surface strengthening treatment to improve its high-temperature resistance, resistance to thermal fatigue, wear resistance, and oxidation resistance. In addition, the design of the roll sleeve must also consider ease of disassembly and maintenance, so that it can be quickly replaced when worn or damaged, reducing the impact on the production line. With the continuous progress of continuous casting technology, the materials and manufacturing processes of continuous casting roll sleeves are also continuously optimized, aiming to further improve the operating efficiency of continuous casting machines and the quality of cast billets, reduce production costs, and promote the green and sustainable development of the steel industry.
