Instructions: the agent is the red phosphorus other chemical elements, through special process configuration. Used for eutectic or eutectic silicon piston alloy for modification of the production process. This agent can refine the total primary silicon crystal silicon, at the same time have degassing refining effect.
Technical features: use this agent to deal with the piston at room temperature tensile strength significantly higher than that of sodium modification treatment of piston, at the same time, with low thermal expansion count, high dimensional stability, high thermal conductivity, wear resistance, corrosion resistance is good wait for a characteristic, metamorphic after long-term and remelting metamorphism can be considered (charge) can greatly reduce casting tendency of osteoporosis. Metamorphic process there is a small amount of smoke production.
Technical parameters: joining temperature (eutectic alloy (such as 108109 alloy) metamorphic temperature of 720 degrees - 720 degrees, hypereutectic alloy metamorphic temperature of 740 degrees - 740 degrees, the higher si content, metamorphic temperature limit, adding amount of 0.3% to 0.3%.
Method of use: liquid aluminum after reaching metamorphic temperature, depth into the crucible with a bell voltage to the reaction so far.
Note: 1. The eutectic alloy to deteriorate after refining, hypereutectic alloy after modification, and then refine it.
2. After processing to stand for 8 to 10 minutes.
Examination metamorphic fracture, fracture surface is flat and level, organization meticulous, something visible small and uniform distribution of silicon at two o 'clock.
