They have possessed high flexibility in their alloying design to increase their performance in heat and wear resistance in comparison with that of conventional wrought steel and cast alloys.
就增高耐热与耐磨耗性能而言,在合金化设计上,烧结合金远比常规的锻钢与铸造合金灵活。
The results of microstructure observation showed that diameter and shape of carbide of the MIM specimens were uniform than those of the wrought steel specimens.
显微组织的观察结果表明,MIM钢试样的碳化物的直径与形状比锻轧钢试样的均一。
Generally, the steel rolling furnace「s service life is 3-10 years, the wrought steel chamber furnace is about 2 years, and the soaking pit side nozzle furnace」s is 3-6 years.
轧钢加热炉的使用寿命一般为3 ~10年,锻钢室式加热炉的寿命约为2年,单侧上烧嘴均热炉的使用寿命一般为3 ~6年。
