Abstract

The invention provides a machining technology for titanium alloys. Titanium sponges are processed into blanks which have excellent machining properties and can be used for producing titanium rods and titanium wires directly. The invention further provides a method for producing titanium rods and titanium wires through the machining technology. The machining technology comprises the steps of electrode pressing: subjecting the titanium sponges to electrode pressing through a pressing machine to form compact titanium sponge pressed block electrodes; vacuum casting: performing vacuum casting on the titanium sponge pressed block electrodes for three times at the temperature in a range of 1700 DEG C to 1800 DEG C and under the pressure of -103 Pa; blooming: performing blooming through an oil press at the temperature of 1000 DEG C to press the block electrodes into square bases; first rolling: rolling the square bases into cylindrical blanks through a rolling machine at the temperature in a range of 970 DEG C to 980 DEG C; and second rolling: rolling the cylindrical blanks into blank parts through the rolling machine at the temperature of 950 DEG C.

Description

technical field [0001] The invention relates to a titanium alloy processing technology, which is particularly applied to the blank processing of titanium alloy, the processing of titanium rod and the processing of titanium wire. Background technique [0002] The spongy metal titanium produced by the metal thermal reduction method is the basic link of the titanium industry. It is the raw material for titanium materials, titanium powder and other titanium components. Turn ilmenite into titanium tetrachloride, put it in a sealed stainless steel tank, fill it with argon gas, and make them react with metal magnesium to get "titanium sponge". This kind of porous "titanium sponge" cannot be used directly, and they must be melted into liquid in an electric furnace before they can be cast into titanium ingots. [0003] In the traditional processing technology of sponge titanium, it is often simply melted and cast as a titanium ingot (blank). This traditional technology has the follo...
