特點(diǎn)：本制劑主要由鎂、鈉、鉀的氯鹽和氟鹽所組成，具有較低的熔點(diǎn)（653K-673K），適當的表面張力，在合金熔煉溫度下熔化成液態(tài)，自動(dòng)形成連續的覆蓋層，由于有特殊無(wú)機添加劑的作用，它會(huì )持續地釋放出惰性氣體，使鎂液表面受到溶劑、氣體復合保護；在爐中長(cháng)時(shí)間靜置不破碎下沉，有效時(shí)間大于三小時(shí)，有害氣體量少，符合工業(yè)衛生標準及廢氣排放要求。

用途：適用于鎂合金和鋁鎂合金的冶煉。

使用方法：用量為1-2%，通常以覆蓋嚴密程度來(lái)確定，在熔煉開(kāi)始時(shí)加入一定數量于坩堝底部熔化后裝入爐料，溶液表面應保持有5-10毫克的覆蓋層。鋁鎂合金加入方法同上，與鋁錠一起熔化，在覆蓋保護條件下加入鎂錠和回爐料。金屬液面如有裸露處，應當及時(shí)補加。

Characteristic: This preparation is mainly composed of chloride and fluoride salts of magnesium, sodium and potassium. It has low melting point (653K-673K), suitable surface tension, melts into liquid at the melting temperature of the alloy, and automatically forms a continuous coating. Because of the role of special inorganic additives, it continuously releases inert gas, which makes the surface of magnesium liquid protected by solvent and gas. Medium and long time standing without breaking and sinking, effective time more than three hours, less harmful gases, in line with industrial health standards and emission requirements.

Usage: Suitable for smelting of magnesium alloys and aluminium-magnesium alloys.

Usage: The dosage is 1-2%, which is usually determined by the degree of tightness of the coating. At the beginning of smelting, a certain amount of melting material is added to the bottom of the crucible and then filled into the furnace. The surface of the solution should be kept 5-10 mg of the coating. The addition method of Al-Mg alloy is the same as that of Al ingot, which is melted together with Al ingot. Magnesium ingot and refining charge are added under cover protection condition. If the metal level is exposed, it should be added in time.
