A non-vacuum preparation method of copper-chromium-zirconium alloy and copper-chromium-zirconium alloy

Abstract

The application discloses a non-vacuum preparation method of copper-chromium-zirconium alloy and the copper-chromium-zirconium alloy. The preparation method comprises the following steps: taking high-purity negative plate copper, copper-chromium intermediate alloy and copper-zirconium intermediate alloy according to proportions and preparing high-purity graphite; the graphite crucible of the intermediate frequency induction furnace is heated to 1150-1300 DEG C, the high-purity negative plate copper and the copper-chromium intermediate alloy are added, and the alloy melt with a temperature of 1210+ / -15 DEG C is formed; the copper-zirconium intermediate alloy is inserted into the melt liquid surface under 50-150 mm by using a feeding tool, the tool is taken out after 3-5 min of heat preservation and stirring; the high-purity graphite is covered on the alloy melt liquid surface and / or inert gas is continuously introduced above; the copper-chromium-zirconium alloy melt is sampled and detected by using a sampling spoon; the copper-chromium-zirconium alloy melt is discharged from the furnace and cast, and the casting temperature is 1200+ / -10 DEG C. The copper-chromium-zirconium alloy is prepared by using the preparation method. The application has the characteristics of low oxygen content, uniform zirconium distribution, small burning loss and low preparation cost.
