[0017] Example 1
[0018] An Os-containing magnesium bath alloy for replacing a lead bath with a high heat capacity at 490°C. By weight percentage, the chemical composition of the alloy is: Ba: 1.4wt.%, Os: 0.5wt.%, Mn: 1.2wt.%, Sc: 0.5wt.%, Sm: 0.2wt.%, Co: 2.5wt% .%, the balance is magnesium. The preparation method of the alloy: the above-mentioned raw materials are added to the induction furnace protected by the atmosphere, and a silicon carbide crucible is used; the alloy solution is formed by induction heating to 700-800 degrees, and the electromagnetic stirring effect is used to fully stir for about 10 minutes; After the liquid is kept at 700-800 degrees for 10 minutes, it is poured into the hot top level equipment for semi-continuous casting into the required round ingots, and the moving speed of the ingots is 6m / min. The material is used for troostite heat treatment of steel materials in magnesium bath; wherein, the use temperature of magnesium bath alloy is 480-550 ...
