Embodiment 1

[0024] Step 1. Mix zero-grade titanium sponge with a particle size of 8mm and molybdenum particles with a particle size of 6mm. After mixing evenly, use a 600T press to apply an axial pressure of 15MPa to press it into an electrode block with a size of 105mm×350mm, and then use the furnace to Weld the electrode blocks in pairs to form electrodes with a size of 105mm×1400mm, and then place the electrodes in a vacuum consumable electric arc furnace. When the smelting vacuum degree is less than 5Pa, start smelting. The smelting current is 1400A, and the smelting voltage is Under the condition of 30V, a Ti-Mo master alloy is obtained by melting once; the content of Mo in the Ti-Mo master alloy is 20%;

Abstract

The invention discloses a method for smelting and producing a TA10 hot continuous rolling square billet by adopting an electron beam cooling bed furnace. The production process comprises the following steps that firstly, titanium sponge with the granularity of 6 mm to 10 mm and molybdenum particles with the granularity of 6 mm to 8 mm are mixed, after being evenly mixed, the titanium sponge and the molybdenum particles are pressed into an electrode block, in-furnace welding is adopted to enable the electrode block to be welded into an electrode, a vacuum arc remelting furnace is used for one-time smelting to obtain Ti-Mo intermediate alloy, and the content of Mo in the Ti-Mo intermediate alloy is 15 percent to 25 percent; secondly, the Ti-Mo intermediate alloy manufactured in the first step is broken in an ingot mode to form Ti-Mo intermediate alloy particles with the granularity smaller than or equal to 3 mm; and the like. The method for smelting and producing the TA10 hot continuous rolling square billet by adopting the electron beam cooling bed furnace is simple in process and convenient to operate, the ingot casting quality is improved, meanwhile, the production process is greatly shortened, the yield is improved, the production cost is greatly reduced, and the billet has the good market competition capability.

Description

technical field [0001] The invention relates to a method for producing TA10 hot rolling billet by smelting in an electron beam cold bed furnace, and belongs to the technical field of titanium alloy production. Background technique [0002] Titanium has excellent corrosion resistance, mechanical properties and process properties and is widely used in the national economy, especially in the production of the chemical industry. Replacing stainless steel, copper-nickel alloy and other rare metals with titanium is of great significance not only to improve the quality of products, but also to prolong the service life of equipment, reduce consumption, reduce costs, improve working conditions and increase labor productivity. [0003] Research shows that: Ti-Pb alloy is currently the best corrosion-resistant titanium alloy, which has been widely used in metallurgy, aviation, petroleum refining, petrochemical and other industrial sectors, and has achieved remarkable results. However,...
