Description
Technical field
The utility model belongs to titanium sponge and produces also-steam stove technical field, is specifically related to a kind of 11t that is applicable to titanium sponge production and combines also-steam stove.
Background technology
In sponge titanium smelting process, in the situation that early stage, raw material and equipment met the demands, going back steaming process production and determined quality product, power consumption, is crucial in sponge titanium smelting technique and important link.
The energy utilization rate that China's titanium industry is produced is greatly improved in recent years, but still has gap with advanced international standard.Analyze as an example of reduction distillation produce titanium sponge by combination method example, China's ton titanium power consumption is down to 6000 kWh/t～8000 kWh/t by 11000 kWh/t at present, is less than 3000 kWh/t and go back steaming process ton titanium power consumption in the integrated process technique of Japan.
At present, owing to abroad titanium metallurgical technology being enforced a tight blockade, force China's titanium sponge to produce away the road of independent research, cause domestic titanium sponge industry production state of the art gap compared with advanced foreign technology larger, be mainly manifested in the aspect such as the optimization of production technique and equipment and the automatization of production process.Domestic current titanium sponge enterprise is external imported technology at the Technology origin of the developing direction of the critical processes such as chlorination, refining, electrolysis.There is not introduction precedent and go back steaming process advanced foreign technology production line, block tight.And domestic titanium sponge industry is for strengthening enterprise competitiveness, all go back successively skill upgrading and the retrofit work of steam stove at present, single stove production capacity tonnage is to maximization future development.
The large-scale inverse u shape of domestic current employing also-steam stove technology be mainly titanium sponge industry Zunyi Titanium Factory of leading enterprise and the Luoyang Shuangrui Wanji Titanium Co., Ltd. faster of growing up in the industry.Zunyi Titanium Factory and Luoyang Shuangrui Wanji Titanium Co., Ltd. are accumulated and are put into practice by knowhow, under the promotion of lifting self market competitiveness, success in succession researched and developed 12t, 10t large-scale energy-saving type inverse u shape also-steam stove technology, and original system is carried out to technological transformation and lifting, put into production, improve single stove production capacity and annual capacity, reduced unit consumption of product and production cost.
