Abstract

The invention relates to a processing process of a tellurium-selenium-copper rod. The tellurium-selenium-copper rod comprises the following components in percentage by mass: 0.4-0.7% of tellurium, 0.004-0.012% of phosphorus, 0.1-0.15% of selenium, 0.05-0.1% of sulphur and 0.1-0.15% of antimony, wherein the ratio of the selenium content to the antimony content is 1:1; the tellurium-selenium-copper rod further comprises any two of the following elements: silver, titanium, cerium, boron, cobalt, chromium, nickel and niobium; and the content of each of the any two elements is 0.001-0.005%. The processing process of the tellurium-selenium-copper rod comprises the following steps: performing upward continuous casting on the tellurium-selenium-copper rod, milling, performing continuous rolling and annealing, drawing, straightening, slitting and the like.

Description

technical field [0001] The invention relates to a processing technology for non-ferrous metal materials, in particular to a processing technology for tellurium selenide copper rods. Background technique [0002] Tellurium copper is a copper alloy grade in the American standard, also known as phosphorus deoxidized tellurium-containing copper. The alloy contains 0.4-0.7% of tellurium, 0.004-0.012% of phosphorus, and the total content of copper, silver and tellurium is greater than 99.9%. Tellurium copper rods are mainly used to make forgings and screw machine products. Typical parts include electrical connectors, automotive parts, switch parts, pipe fittings, solder tips, torch tips, transistor bases and furnace brazed assembled parts. It is a free-cutting copper alloy with 85% machinability of C36000 (free-cutting brass), and is suitable for cold and hot working. [0003] Chinese patent CN200810147883.3 discloses tellurium-copper alloy materials used in the electrical powe...
