摘要
介绍了浓硝酸生产中的主要腐蚀现象 ,指出采用先进的自动控制的硝酸镁法浓缩稀硝酸生产工艺 ,其重要设备重点部位分别选用 1Cr18Ni9Ti不锈钢、高硅铸铁、铝材和C4钢及非金属材料 。
The major corrosion in the production of high-concentration nitric acid was described. The corrosion in producing the high-concentration nitric acid from the low-concentration by magnesium nitrate process could be effectively controlled if 1Cr18Ni9Ti stainless steel, high-silicon cast iron, aluminum, C4 steel and non-metal materials were selected for the important locations of the equipment.
