在热模拟机上进行高温压缩试验，测定了热轧管线用钢在单道次、多道次等不同条件下的变形抗力，并研制了相应的变形抗力模型及残余应变率模型。综合测定了此种钢在１７００ｍｍ热连轧机上试轧时的轧制力及有关数据，利用实测压力逆算应力状态影响系数，建立了精轧各机架应力状态影响系数经验模型。
The high-temperature compression test was carried out on a thermal simulator to measure the deformation resistance of hot-rolled pipeline steel under single-pass and multi-pass conditions. Corresponding deformation resistance models and residual strain rate models were also developed. The rolling force and related data of this kind of steel on the 1700mm hot strip mill were comprehensively measured. Based on the measured pressure, the effect coefficient of stress state was calculated, and the experience model of the influence coefficient of stress state of each rolling stand was established.
