固体硼化处理是在1000～1050℃的煅烧的碳化硼粉末中进行的。然后将模具放入盐浴炉中淬火(780℃),并依次进行水冷和油冷,再在180℃温度下回火两小时。材料为y12A钢的凹模,经过固体硼化处理和淬火以后,其内径(工作直径)一股要减小0.19～0.26毫米。液体硼化处理是在850～950℃的熔融物中进行的,熔融物的成分(按重量)为:硼砂(Na_2 B_4O_7)73～79％;氯化钠(NaCl)15～20％;黑硼粉(B)5～7％。这种熔融物可以硼化处理的同时进行淬火前的加热。
The solid boriding treatment is carried out in a calcined boron carbide powder at 1000 to 1050 ° C. The mold was then quenched (780 ° C) in a salt bath furnace, followed by water and oil cooling and tempering at 180 ° C for two hours. Materials for the y12A steel die, after solid boronization and quenching, its diameter (working diameter) to reduce 0.19 ~ 0.26 mm. The liquid boric acid treatment is carried out in a molten material at 850-950 ° C, the composition of which by weight is 73-79% of borax (Na 2 B 4 O 7), 15-20% of sodium chloride (NaCl) Powder (B) 5 ~ 7%. This melt can be boronized while heating before quenching.
