Problems solved by technology

[0003] The technical problem to be solved by the present invention is that for domestically produced mainstream titanium alloys, pollution is likely to occur during machining, and the contaminated titanium shavings, ingot head and tail, The amount of slats is very large, and at the same time, they are easily contaminated during processing and cannot be reused

Embodiment 1

[0018] (5) After the charging is completed, apply a voltage of 32V and move the electrode rod down. When the electrode rod is in contact with the furnace material in the crucible of the solidification furnace and generates current, gradually increase the current. When the current is loaded to 10000A. Keep the current constant by moving the electrode down. After the material in the crucible is completely melted, keep the current for 10 minutes, so that the material in the crucible is fully melted, and the impurities with high density in the crucible have enough time to sink. After sufficient settlement, the molten titanium liquid in the crucible is poured into the round copper crystal with water cooling on the outer wall of the bottom seal through the casting mechanism. After the titanium liquid in the crystallizer is fully cooled, the quality of the original TC4 is changed to low-cost high-quality TA18 alloy quenched and tempered titanium ingot.

Abstract

The invention discloses a titanium alloy hardening and tempering method, and belongs to the technical field of titanium alloy smelting engineering. The method comprises the following steps: determining the mark of the titanium alloy to be produced according to the national standard, averaging in a component range specified by the national standard, taking the average value as a reference value, selecting alloy reclaimed materials of the same batch number, and performing chemical component inspection; and taking an average value for later use. By the adoption of the method, hardening and tempering can only be conducted on a main alloy element component from low to high or from high to low or from low to high. By the adoption of the method, impurities of the original recycled materials can be removed, the purification effect is achieved, quality adjustment of the titanium alloy can be achieved, the utilization rate of the recycled materials is increased, the flow direction of the alloy is increased, and the flow rate / utilization rate of the alloy is increased.

Description

technical field [0001] The invention relates to a titanium alloy quenching and tempering method, which belongs to the technical field of titanium alloy smelting engineering. Background technique [0002] After more than ten years of rapid development of my country's titanium industry, the production capacity is seriously overcapacitated. The supply of common mainstream products of titanium materials exceeds demand, such as TC4 and other alloys, and the amount of titanium shavings, ingot heads and tails, slats, etc. formed by the processing of mainstream products is very large. At the same time, it is easily polluted during processing and cannot be reused. The application of titanium materials in the traditional welding electrode method has high requirements on the size of titanium materials and the purity of raw materials, and the utilization rate of titanium materials is limited, resulting in low comprehensive yield of raw materials and high production costs of titanium mate...
