摘　　要：对高速线材轧机精轧机组中使用的碳化钨辊环进行了受力分析。指出了轧制应力、热应力及装配应力在辊环断裂过程中的作用。认为辊环的质量控制关键在于辊环的合理使用上,主要从轧辊的冷却、修磨、合理轧制、合理选用这几方面来解决辊环的碎裂问题。In the paper,it is introduced the force analysis of tungsten carbide roll collars used on finishing mill group in high speed wire rod, and pointed out the effects of rolling stress, thermal stress, and assembly stress in the process of fragmentation for roll collars. It is got that fair use of roll collars is the key to quality control of roll collars, and the problem of fragmentation could be solved by cooling, grinding, rational rolling and selecting roll collars.
