Process of electron beam cold bed furnace for recycling and remelting TC11 scraps

Abstract

The invention discloses a process of an electron beam cold bed furnace for recycling and remelting TC11 scraps, and belongs to the technical field of titanium alloy preparation. The method comprises the steps that S1, in combination with the size of a material box, a thin titanium plate is selected to be welded into a titanium frame, and weighing is carried out; S2, the weight of the TC11 scraps capable of being contained in the titanium frame is estimated according to the stacking density of the TC11 scraps, the adding amount of an A1 plate is calculated, and cutting is carried out according to requirements; S3, the TC11 scraps and the A1 plate are stacked to be placed in the titanium frame, and materials are dried; and S4, the dried materials are fed into the electron beam cold bed furnace for smelting, and TC11 titanium alloy is obtained through one time of smelting. The reliable, practical and efficient treatment scheme for recycling and remelting the TC11 scraps at low cost is provided, meanwhile, the process is coherent in technological process, convenient and fast to operate and thorough in treatment, and the need of recycling and remelting the TC11 scraps of an electrode incapable of being pressed can be met.

Description

technical field [0001] The invention relates to a process for recovering and remelting TC11 scrap, in particular to a process for recycling and remelting TC11 scrap in an electron beam cooling hearth furnace, belonging to the technical field of titanium alloy ingot preparation. Background technique [0002] The economic development model of recycling renewable resources and continuous recycling of materials is currently becoming a global trend, and the renewable resource recycling industry that follows the path of sustainable development has become a key support object of the state. Titanium alloy waste is a renewable resource, and its comprehensive utilization saves a lot of energy compared with the development of primary mines. TC11 alloy has a high melting point, strong corrosion resistance, high specific strength, and good plasticity. It is an ideal aerospace engineering structural material. From TC11 rough ingot to light ingot, the amount of chips generated by drilling ...

Problems solved by technology

However, since the main alloying element Al in TC11 scrap is much larger than the matrix element, if it is directly remelted, the Al element will inevitably be volatilized and lost in a large area, so that the chemical composition of the final TC11 ingot cannot meet the standard

The supplementary amount and supplementary method of Al element are so difficult that the technology of recovering remelted TC11 scrap from electron beam cooling hearth furnace has not yet been reported.
