Problems solved by technology

[0002] At present, P (phosphorus) is generally used in the modification of aluminum-silicon alloys. Modifiers include modifiers prepared with red phosphorus and intermediate alloys such as P-Cu, Al-P, etc. The former has a large loss during processing, and the smog will cause great environmental pollution. , the cost of the latter modificator is very high

Abstract

The invention discloses a P-Fe alloy type inoculant and a method for applying the P-Fe alloy type inoculant to aluminum-silicon alloy melting. Based on the aluminum-silicon alloy to be prepared, the P-Fe alloy type inoculant consists of the following components in percentage by weight: 0.1 to 0.2 percent of P-Fe alloy, 0.1 to 0.15 percent of sigma Re, less than or equal to 0.2 percent of Mn, and the balance of Fe, wherein the weight content of P in the P-Fe alloy is 20 to 30 percent. A phosphorus-iron inoculating process is formed in the aluminum-silicon alloy melting by adopting the P-Fe alloy type inoculant, and can inoculate and thin a material; and by the process, the efficiency can be improved, the environmental pollution can be reduced, and cost and material consumption can be reduced.

Description

technical field [0001] The invention relates to an auxiliary agent for alloy smelting, specifically a phosphorus modifier and its application method in aluminum-silicon alloy smelting. Background technique [0002] At present, P (phosphorus) is generally used in the modification of aluminum-silicon alloys. Modifiers include modifiers prepared with red phosphorus and intermediate alloys such as P-Cu, Al-P, etc. The former has a large loss during processing, and the smog will cause great environmental pollution. , the cost of the latter modificator is very high. [0003] With the rise of raw material prices, cost reduction is imperative, and through technological innovation, a new high-phosphorus master alloy modifier is selected to be used on the aluminum-silicon alloy of the piston to reduce the cost of the modifier. Added in a smelting furnace or alloy smelting to reduce material loss. Contents of the invention [0004] The purpose of the present invention is to provide...
