摘　　要：以往工作辊辊径主要根据最小可轧厚度计算确定,随着工艺润滑技术的发展,最小可轧厚度已不再是制约辊径的瓶颈,而轧辊的热平衡及辊间接触应力问题成为决定工作辊直径大小的主要决定因素。如今,在进行工作辊辊径计算时,首先应基于最小带材厚度确定工作辊的最大直径,然后根据轧辊的热平衡条件确定工作辊的最小辊径。在此基础上,结合工程经验先设定一个辊径值,然后针对该辊径值进行辊间接触应力核算、扭矩核算、咬入角核算及辊系稳定性核算,待核算结果全部通过后方能确定为轧辊辊身直径。In the past, the work roll diameter was determined with minimum allowable rolling thickness. With the development of process lubrication technology, minimum allowable rolling thickness is never the bottle neck to restrict roll diameter. The hot balance and contact stress between rolls have become the primary factors that determine work roll diameter. Now, for the calculation of work roll diameter, firstly the maximum diameter is determined with minimum strip thickness and the minimum diameter is determined with the hot balance of the roll. Based on this and the engineering experience, a diameter value is set up. And then, with this diameter value, Proof calculations on contact stress, torque, bite angle and stability of the rolls are performed. The work roll diameter can be determined only when the results of all proof calculations are acceptable.
