特点:是以RJ-2溶剂为原料加入多种氟化物,对镁和镁合金熔体中的氧化镁和其他杂质有溶解和吸附作用。又加入了加重剂,使熔剂的比重大于金属溶体的比重。此熔剂加到镁和镁合金熔体中后,即开始缓慢下沉,同时溶解和吸附金属熔体中的氧化物及气体,起到了除渣和静化的作用。
用途:ZM1合金精炼和覆盖剂。
Characteristic:It is the powder,putting kinds of fluoride into RJ-2 ,which can liquate and absorb the MgO and other impurity in magnesium and magnesium alloy.The dense medium solid in RJ-4 will increase the specific gravity and improve the quality of the cast.
Purpose: ZM1 alloy refining and covering agent.
