特點：本制劑主要由鎂、鈉、鉀、鈣等氯鹽和氟鹽組成，由于配方精密，液態(tài)密度，黏度合適，具有的精練效果，兼有覆蓋保護(hù)作用。比重為1.8-2.0與合金液有較大的比重差，化學(xué)穩(wěn)定性好，不與合金、爐襯和爐氣發(fā)生化學(xué)反應(yīng)，不產(chǎn)生熔劑雜質(zhì)。有害氣體量少，符合工業(yè)衛(wèi)生標(biāo)準(zhǔn)及廢氣排放要求。

用途：適用于鎂、鎂合金及鋁鎂合金。

　　使用方法：用量2-3％。當(dāng)鎂合金采用電阻坩鍋爐熔煉升溫***740℃時，不斷撒入精煉劑于液面，同時用精煉勺上下攪動，使鎂液循環(huán)流動，以延長熔劑液滴的流程，增加熔劑與氧化夾雜接觸吸附機(jī)會，通常保持10分鐘左右液面呈光亮鏡面為止

Features: This preparation is mainly composed of magnesium, sodium, potassium, calcium chloride salts and fluoride salts. Because of its unique formula, liquid density and proper viscosity, it has excellent refining effect and protective covering effect. The specific gravity of 1.8-2.0 is worse than that of alloy liquid. It has good chemical stability. It does not react with alloy, lining and furnace gas, and does not produce flux impurities. The amount of harmful gases is small, which meets the requirements of industrial hygiene standards and exhaust gas emission. Usage: Suitable for magnesium, magnesium alloy and Al-Mg alloy. Usage: 2-3% dosage. When magnesium alloys are melted in resistance crucible boilers and heated to 740 C, the refining agent is continuously sprayed on the liquid surface. At the same time, the refining spoon is stirred up and down to make the magnesium liquid circulate, so as to prolong the flow of flux droplets and increase the chance of contact and adsorption between flux and oxide inclusions. Usually, the liquid surface remains bright mirror for about 10 minutes.
