为了提高合金球墨铸铁轧辊的综合机械性能和使用性能,一般采用将原始组织部分或全部重结晶的高温热处理方法.本文研究了Ⅱ类退火对不同Cr、Ni、Mo、Cu元素含量的合金球墨铸铁性能的影响(表1).在乌克兰冶金研究院实验工厂用200kg酸性炉衬的感应炉进行了试验性熔炼. In order to improve the mechanical properties and serviceability of the alloy ductile iron roll, the high temperature heat treatment method of recrystallizing some or all of the original structure is generally adopted.In this paper, the effects of annealing on the ductile iron with different contents of Cr, Ni, Mo and Cu The impact of performance (Table 1) was experimentally smelted in an experimental furnace of Ukraine’s Metallurgical Institute with a 200 kg acid furnace lining induction furnace.
