通过两年来连续不断的改进和试验,终于找到了一种微粒钢球淬火的新方法,即盐浴炉加热,碱溶液冷却的淬火方法。设备为C—45盐浴炉,盐的成分是BaC172％+NaCl28％,脱氧剂TiO_2+石英砂,每班脱氧一次,一次用0.2公片。冷却介质为温度20—60℃、浓度40—50％的NaOH水溶液。经过半年的生产实践证明,该法能100％的确保质量,且操作简便。附图8幅，参考文献12种。 After two years of continuous improvement and testing, finally found a new method of particle ball quenching, that is, salt bath furnace heating, quenching alkaline solution cooling method. Equipment for the C-45 salt bath furnace, the composition of the salt is BaC172% + NaCl28%, deoxidizer TiO_2 + quartz sand, deoxidation once a class, once with 0.2 tablets. Cooling medium temperature 20-60 ℃, the concentration of 40-50% NaOH aqueous solution. After six months of production practice has proved that the law can be 100% to ensure quality, and easy to operate. Figure 8, 12 references.
