- 摘要:
- 采用热喷涂和中频感应加热联合渗铝的方法，成功地生产出超长渗铝管，其关键是选择适当的功率、感应温度和控制钢管的移动速度。已经生产的54根长度12m的Cr5Mo钢焦化炉渗铝管，渗层厚度可达0．1～0.3mm，在炼油生产中使用一年，炉管表面无氧化无腐蚀。
It uses the heat spraying and induction heat aluminizing process to product successfully ultra-long aluminizing pipe. Its key technology is reasonable power choice, induction temperature and pipe moving speed. 54 pieces of CrSMo aluminizing pipe with 12 meters long and 0.1~0.3 mm aluminizing thick-ness were fabricated and have been used in refinery units for one year. As a result there is no oxide and no corrosion.1998,4(4): 37-39 收稿日期：1997-11-17参考文献：
