Embodiment 1

[0032] 1) Prepare copper, chromium, titanium, and zirconium raw materials according to the total mass percentage of 99%: 0.7%: 0.1%: 0.2%. Among them, the raw materials of chromium, titanium and zirconium are copper-chromium alloy, copper-titanium alloy and copper-zirconium alloy respectively, and the copper raw material is copper in copper-chromium alloy raw material, copper-titanium alloy and copper-zirconium alloy raw material, and the balance is made up with pure copper. The use of the alloy as the material can prevent the highly active chromium and zirconium elements from being burned during the preparation process and affecting the composition of the alloy. Put pure copper and copper-chromium alloy raw materials in a crucible, cover with charcoal, and heat up to the melting temperature of the raw materials at 1180°C; the error range of the temperature should be controlled between 1175°C and 1205°C; then keep warm until the alloy melts.

[0042] 1) Prepare copper, chromium, titanium, and zirconium raw materials according to the total mass percentage of 99%: 0.7%: 0.05%: 0.05%. Among them, the raw materials of chromium, titanium and zirconium are copper-chromium alloy, copper-titanium alloy and copper-zirconium alloy respectively, and the copper raw material is copper in copper-chromium alloy raw material, copper-titanium alloy and copper-zirconium alloy raw material, and the balance is made up with pure copper. The use of the alloy as the material can prevent the highly active chromium, titanium, and zirconium elements from being burned during the preparation process and affecting the composition of the alloy. Put pure copper and copper-chromium alloy raw materials in a crucible, cover with charcoal, and heat up to the melting temperature of the raw materials at 1180°C; the error range of the temperature should be controlled within ±2°C; then keep warm until the alloy melts.

Abstract

The invention discloses a method for upward traction continuous preparing of a copper, chrome, titanium and zirconium alloy rod. Fine copper and a copper chrome alloy raw material are placed into a crucible, are covered with charcoal, and are heated to be not lower than 1180 DEG C + / -5 DEG C and not higher than 1200 DEG C + / -5 DEG C, after an alloy is fused, copper titanium and copper zirconium alloy raw materials are added into the crucible and are subject to heat preservation and standing for not longer than 1 min, and the melt temperature is measured; and after melt reaches 1180 DEG C-(10*chrome mass percent+50*titanium mass percent+100*zirconium mass percent) DEG C, (the chrome mass percent in the alloy is not lower than 0.2 and not higher than 0.7, the titanium mass percent is not lower than 0.05 and not higher than 0.1, the zirconium mass percent is not lower than 0.05 and not higher than 0.2, and the balance is copper and impurities) the alloy is subject to upward continuous traction, and a continuous length copper, chrome, titanium and zirconium alloy rod material is obtained and rolled. According to the method, upward traction continuous casting of a copper rod by 100 m or above can be achieved, and the scale production and application prospect is achieved.

Description

technical field [0001] The invention relates to a method for continuously preparing copper-chromium-titanium-zirconium alloy rods. Background technique [0002] Copper-chromium-titanium-zirconium alloy has good electrical and thermal conductivity, high hardness, good wear resistance, high softening temperature resistance, and is often used in contacts and mold materials. However, at present, the production of copper-chromium-titanium-zirconium alloy at home and abroad only stays in the preparation of a single piece, and the continuous production of the alloy is not yet possible. One of the problems is that the billet cannot be continuously prepared, and the copper-chromium-titanium-zirconium alloy billet cannot be continuously and efficiently produced. for subsequent production. Contents of the invention [0003] The method for continuously preparing copper-chromium-titanium-zirconium alloy rods provided by the present invention is aimed at problems such as easy rod break...
