Embodiment 1

[0012] Example 1: Preparation of bulk phosphorus copper master alloy

[0013] Step 1. Melting phosphorus Put 500kg of solid yellow phosphorus in the phosphorus melting device, heat and keep the temperature of the phosphorus liquid at 70°C;

[0014] Step 2. Phosphorus pressing: Pass the phosphorus liquid in the phosphorus melter into the phosphorus press, fill the phosphorus press with nitrogen and keep the temperature of the phosphorus liquid at 60°C;

[0015] Step 3. Phosphorus infusion: pass the phosphorus liquid in the phosphorus press into the phosphorus infusion device according to the ratio;

[0016] Step 4. Smelting Put 500kg of electrolytic copper in the melting furnace, heat and keep the furnace temperature at 1150°C, cover the surface of the copper liquid in the melting furnace with a charcoal layer, so that the copper liquid is always isolated from oxygen, and directly extend the phosphorus feeder into the copper liquid , immersed in copper liquid, phosphorus liqui...

Abstract

The present invention relates to one kind of P-Cu mother alloy comprising P 14.5-15 wt% and Cu 84.499-84.999 wt%. The alloy of the present invention has high P content and low impurity content.

Description

Technical field: [0001] The invention relates to a phosphor copper master alloy. The invention belongs to the technical field of copper alloy materials. Background technique: [0002] Phosphor copper master alloy is an important master alloy used in the manufacture of brazing materials, metal smelting and oxygen-free copper pipes. Its quality directly affects the performance of brazing materials and the quality of non-ferrous metal smelting. Before the present invention was made, red phosphorus was generally used to produce phosphor-bronze master alloys by traditional techniques. When this method is smelted, there is a lot of smoke and dust, and the phosphorus content in the alloy is low, only up to 13%. Invention content: [0003] The object of the present invention is to overcome above-mentioned deficiency, provide a kind of phosphorus copper master alloy in the alloy high content of phosphorus, low impurity content, furnace and furnace composition balance. [0004] T...
