In the high-standard factory building, dozens of equipment are distributed among them, and workers are debugging the equipment nervously and orderly; at the same time, the production line of the smelting workshop is also running at full speed and running rapidly. Recently, the Marriott Titanium 5G Intelligent Titanium Smelting Industrial Park project located in Baoji Comprehensive Bonded Zone has been officially put into operation.
The Marriott Titanium 5G Intelligent Titanium Smelting Industrial Park project has a total investment of 1.1 billion yuan, building 2 high-standard industrial factories and 1 R & D building, and introducing internationally leading titanium and titanium alloy ingot smelting production lines and electrode automatic welding production lines. The project is divided into Two phases are carried out simultaneously. It is understood that the project started in January 2023 and was completed and put into operation in just one year. Currently, production of the first phase has begun. "In accordance with the simultaneous plan of 'installation, debugging, and production', the production line of the smelting workshop has been put into operation, and equipment such as 15-ton plasma welding boxes and 20-ton consumable furnaces are being debugged. It is expected to achieve full capacity operation before June this year." Introduction to the project leader.
It is understood that after the project is put into operation, it can reach an annual production capacity of 25,000 tons of titanium and titanium alloy ingots, achieve an annual output value of 2.2 billion yuan, and can attract more than 300 jobs, which will improve Baoji's titanium smelting and titanium ingot production capacity.According to the announcement of the State Intellectual Property Office, Longbai Group Co., Ltd. applied for a project titled "A Method for Preparing Calcined Crystal Seeds from Titanic Dichloryl Solution, a By-Product of Chlorination Titanium Dioxide", Publication No. CN117361617A, and the application date is October 2023.
The patent abstract shows that the present invention discloses a method for preparing calcined seeds by using titanium oxychloride solution, a by-product of titanium dioxide by chlorination method, which comprises the following steps: S1. Taking and beating the filter cake after alkali washing to obtain slurry I, adding titanium oxychloride solution, adjusting the pH to 3.5 - 5, and obtaining slurry II; S2. Heating the slurry II to 55 - 65℃ at a rate of 0.3 - 0.5℃/min, then adding hydrochloric acid solution, heating the temperature to boiling at a rate of 0.3 - 0.5℃/min, maintaining the boiling for 2 - 4 hours, adding water to dilute until the titanium dioxide content in the material is 90 - 120g/L, and obtaining calcined crystal seeds. The method of the application can realize hydrochloric acid and TiO in titanium oxychloride.
