            Founded in 2006, Baoji First Titanium Industry (Group) Co., Ltd. is a nationally recognized high-tech enterprise. It is located at No. 218 Gaoxin Avenue, Gaoxin District, Baoji City. It has a land use right of 66 mu and a registered capital of 80 million yuan. . Invested 300 million yuan to build a non-ferrous metal smelting, forging and machining production line such as titanium and titanium alloy. It has an annual production capacity of 2,000 tons of molten casting, 30,000 tons of forging and 6,000 tons of titanium for production and processing capacity. , titanium products, titanium equipment, more than 50 kinds of titanium and titanium alloy products, mainly: ingots, rods, blocks, cakes, rings, tubes, plates, wires, shaped forgings, standard parts and tungsten, molybdenum, zirconium, tantalum , nickel, tantalum, niobium and other rare metal products.

          ?The company has strong technical research and development strength, and has complete, systematic rare metal processing and production, research and design, from new product design, research and development, to smelting, forging, rolling, machining, product finishing, physical and chemical inspection and analysis, non-destructive testing, and metering control. system. The 3 ton vacuum consumable electric arc furnace jointly developed by the company and related research institutes has filled the gap of China's private titanium processing enterprises. The equipment adopts Siemens Siemens computer control system, high-precision electronic weighing system, remote camera observation system and important process. The parameter storage and printing system can be operated remotely under the video of the control room to realize the full automation of the melting process, so that the titanium ingot has high yield and uniform chemical composition without segregation...
