不锈钢耐酸管
The main equipment such as stainless steel converter, fire tube boiler, main blower and concentrated acid pumps were made at home.
主要设备,如不锈钢转化器、火管锅炉、主鼓风机、浓硫酸泵等均为国产。
The results showed that the existence of dark-yellow stains in stainless tube after acid cleaning results from the contamination of chalks, the non-uniformity of chromium in raw material and the slow cooling rate in solid solution treatment.
结果表明:粉笔污染、原材料中铬含量的不足以及固溶处理中冷速较慢均会导致不锈钢焊管经酸洗后表面出现暗黄色花斑。
