前言随着我国化肥、石油工业的发展,对耐蚀、耐高温材料的要求,也就更加迫切了。为满足日益发展的石油化工工业的需要,尤其化肥厂碳铵系统和炼油厂高温重油部位对耐蚀材料的要求,鞍钢广大职工和化肥、石油战线工人阶级一起,按照毛主席“独立自主、自力更生”的教导,进行了12SiMoVNbAl 的研究试验工作。几年来,在试验室内进行了各种耐蚀性和综合性机械性能试验,并挂了大量试片进行耐蚀试验。同时在30吨平炉上生产了一部分钢,轧成6～18毫米板材和少量管材,进行了工业性试验。试验结果表明:12SiMoVNbAl 在高温
Preface With the development of China’s chemical fertilizers and petroleum industries, the requirements for corrosion-resistant and heat-resistant materials are even more urgent. In order to meet the needs of the growing petrochemical industry, in particular the requirements of the chemical fertilizer plant’s ammonium bicarbonate system and high temperature heavy oil refinery parts on anticorrosion materials, the vast majority of staff and workers of Ansteel, together with the working class of oil and chemical workers and oil producers, follow Chairman Mao’s principle of “independence and self-reliance” The teaching of 12SiMoVNbAl research work. In recent years, various corrosion resistance and comprehensive mechanical properties tests have been carried out in the laboratory, and a large number of test specimens are hung for corrosion resistance test. At the same time, a part of the steel was produced on a 30-ton open hearth and rolled into 6 to 18 mm plates and a few tubes for industrial tests. The experimental results show that: 12SiMoVNbAl at high temperature
