摘要

The present invention relates to a method for producing an ultrafine Si-micron treatment agent for an over-process Al-Si alloy, wherein an extruded material obtained by hot extrusion after mixing and degassing an Al powder and a Cu-P powder is subjected to heat treatment at a temperature below the melting point. A method for producing a primary Si microfinishing agent of an over-processed Al-Si alloy is provided.;According to the present invention, when the phosphorus is added, problems such as gas mixing due to high temperature and damage to the furnace wall due to long-term maintenance occur, whereas when Al-13.5Cu-1.5P extruded material is used, the amount of P added is low and low. Even if the holding time is short in the molten metal of the temperature, the degree and effect of miniaturization of primary Si is excellent, so it can be very useful for practical operation.
