Abstract

The invention discloses a method for producing titanium slabs efficiently. Electron beam cold hearth furnaces of six electron guns are used, raw materials of which components are selected are placed in bulk material feeders or bar material feeders of the electron beam cold hearth furnaces, smelting is conducted, then obtained cast ingots are cooled and are discharged out of the furnace, and finished products are obtained. According to the method, the raw materials in an original state are used directly for smelting, crushing of recycled materials, mixing of titanium sponge materials, electrode block pressing and electrode welding are avoided, slab ingots smelted through optimization design are two cast ingots of 200*1290*5000mm which are produced in one furnace, the weight is about 12 tons, and the slab ingots are not required to be smelted twice or to be forged can be used in rolling, so that the production flow and the production period are shortened, the production cost is reduced, and the efficiency is improved greatly.

Description

technical field

[0001] The invention relates to a material processing technology, in particular to a method for efficiently producing titanium slabs. Background technique

[0002] The existing technology is mainly the method of VAR melting round ingot + billet forging. Melting is carried out by a vacuum consumable arc furnace (VAR), which requires the recycled material to be broken into chips and mixed with sponge titanium, then pressed into electrode blocks, welded in a vacuum welding box, and then vacuum arc furnace (VAR ) first smelting, second smelting or even third smelting. The ingot after smelting is a round ingot, which is forged after machining. It needs to be forged several times to become a cuboid slab before it can be used for plates. Production. And the flatness of the forged slab is poor, the surface oxide layer is thick, and the yield is low. Therefore, the traditional method is not only limited in the shape of the raw material, but also has high processing...
