(一)前言 热处理加热炉是现代冶金、机械、石油和化工等工业部门广泛使用的设备。为了满足在各种不同工作条件下使用的要求,炉用耐热钢应该具有一定的高温强度,足够的抗氧化性能和抵抗其他加热介质腐蚀的性能,良好的耐热疲劳性,长期在高温工作后组织的稳定性(长期加热后应具一定的冲击韧性)以及良好的冶炼、铸造、锻造、焊接和切削加工等一系列工艺性能。
(A) Preface Heat treatment furnace is a widely used equipment in modern metallurgy, machinery, petroleum and chemical industries. In order to meet the requirements of the use in a variety of different working conditions, furnace heat-resistant steel should have a certain high temperature strength, adequate oxidation resistance and resistance to corrosion of other heating media, good thermal fatigue resistance, long-term work at high temperatures Post-organizational stability (long-term heating should have a certain impact toughness) and good smelting, casting, forging, welding and cutting and a series of process performance.
