<jats:p>Roll collar is one of the major consumption of spare parts in steel rolling production,it is excessive alternating thermal stress in the harsh working conditions. It is very important to control their size and variation of temperature. Temperature variation is unable to use experimental methods, but using the numerical solution is a proven method. The horizontal roller of Universal rolling mill is an exceptional tool for large. The research of temperature field of roll collar undoubtedly is of great significance to provide reasonable suggestions to rolling, extend the life of roll ring, and controll geometric accuracy and surface quality of the work piece.</jats:p>
