Embodiment Construction
[0025] As shown in the figure, a recovery method of TC4 titanium alloy residue EB cold hearth furnace smelting comprises the following steps:
[0026] Step 1. Select the TC4 titanium alloy residue to be processed and remove impurities on its surface, and obtain a clean and dry titanium residue after drying for subsequent use;
[0027] Step 2. Select a TC4 titanium plate with a thickness of 2~10mm for sizing, and use the sized titanium plate to prepare a titanium residue charging box with an upper opening, and measure the TC4 titanium alloy residue after step 1 , so that the size of the TC4 titanium alloy residual material after the sizing is smaller than the size of the charging box, for standby;
[0028] Step 3, select the pure aluminum coil to cut to length to obtain an aluminum sheet, and the cut-to-length specification is consistent with the inner cavity size of the titanium residual material charging box prepared in step 2;
[0029] Step 4. Since the main alloying elemen...

The invention provides a recovering method for TC4 titanium alloy residual materials and relates to the technical field of titanium material machining. The to-be-treated TC4 titanium alloy residual materials are selected firstly, and surface impurities of the TC4 titanium alloy residual materials are cleared; then TC4 titanium plates are selected to be subjected to sizing for titanium residual loading box preparation; a certain mass of the TC4 titanium alloy residual materials with impurities being removed and aluminum thin plates prepared from aluminum coils are weighed; then alternative laying material distribution is conducted in a titanium residual loading box till box loading is completed; and the loading box which completes material distribution is sequentially subjected to smelting, solidifying, ingot pulling, cooling and machining, and then a product is manufactured. According to the recovering method for the TC4 titanium alloy residual materials, the problems that the shape of traditional titanium residual materials is poor in applicability, the production process is long, cost is high, the detrimental impurity element increment is large, and high-density and low-density inclusions are not prone to being removed are solved.
Description
technical field [0001] The invention relates to a titanium material processing technology, in particular to a method for recovering TC4 titanium alloy residues. Background technique [0002] Ti-6Al-4V (TC4) titanium alloy has high strength, excellent comprehensive performance and good processing performance. It is widely used in aviation, ships, weapons, sports and other fields. Its production accounts for more than 50% of the total output of titanium alloys. The high cost limits its further popularization and application, so countries all over the world are exploring techniques and methods to reduce costs. Under the current situation that the cost of titanium sponge raw materials cannot be further significantly reduced, recycling titanium alloy residues is one of the most effective ways to reduce costs. The existing technology mainly adopts vacuum arc furnace (VAR) smelting and recycling, and the process route is "titanium residual material sizing → surface treatment → bin...
