1.According to the distribution of temperature field, the time of compressed air should be controlled. The ideal sorbite can be obtained.
根据重轨温度场的变化规律，控制喷风时间，最终得到理想的索氏体组织。
2.With the decrease of finishing rolling temperature, the grain size is refined apparently and the contents of sorbite is increased.
随着终轧温度的降低，热轧材组织得到细化，索氏体含量提高。
3.Microstructure of working layer in the barrel : pearlite or tempered sorbite .
辊身工作层金相组织为：珠光体或回火索氏体。
4.The results show that X80 pipeline steel obtains sorbite after quenching and tempering, gets pearlite by normalizing.
结果表明：X80钢经调质处理后得到索氏体，正火得到珠光体。
5.The roll barrels are mainl composed of pearlitic or temper sorbite in the microstructure.
辊身金相组织为珠光体或回火索氏体。
6.Increasing the cooling rate can increase the content of sorbite and decrease the content of network cementite;
提高冷却速度可以增加索氏体含量、降低网状渗碳体含量；
