This product is a kind of inorganic salt phosphorus salt as the main metamorphic element with other elements precision composite, mainly on eutectic, hypereutectic aluminum-silicon alloy has a good metamorphic effect. In the current production process of domestic piston industry, phosphorus and salt compound modifier has become the preferred metamorphic product in the industry with its unique and irreplaceable advantages

• Shape: White cylinder (0.5kg/ block)

• Processing temperature: 760℃ ~ 800℃

• Applicable alloys: eutectic Al-Si alloys (such as 108, 109 alloys) and hypereutectic Al-Si alloys

Major advantage

1. The tensile strength of piston treated with this agent at room temperature is nearly 20% higher than that treated with sodium salt modifier, and the expansion coefficient is small and the volume stability is good

2, has high thermal conductivity, wear resistance, corrosion resistance, casting processing is easy, high surface finish

3, with long-term performance and remelting, the alloy treated with this modifier is refined, not only will not make the metamorphic effect decline, but will make the primary silicon distribution more uniform

4, the casting fluidity is good, greatly reducing the shrinkage and shrinkage tendency of the casting, and improving the piston yield

5, melting absorption fast, in the deterioration of the basic smokeless, tasteless, non-toxic, not easy to inhale, not stick to the crucible and tools, easy to operate

6. Convenient and safe storage and transportation

Usage method

After the alloy rises to a certain temperature, the slag is lifted, and the modifier is pressed into the depth of the crucible with a bell jar or a ladle until the reaction is complete, and it is left for 10 minutes before refining and casting

Pay attention to key points

The first is the temperature, the second is the amount of addition, and the third is the resting time
