Abstract
The invention discloses a method for reducing a chlorine impurity in titanium sponge by acid-washing; the method comprises the following steps of: taking the high-chlorine titanium sponge produced by adopting a reduction-distillation method and hydrochloric acid with 0.5-5% of mass concentration, soaking the titanium sponge in the hydrochloric acid for 0.5-2 days according to a mass ratio of the titanium sponge to the hydrochloric acid being 0.7-1.2:1, and then cleaning the titanium sponge for 4-6 times by using water with 5-7 times volume of hydrochloric acid, and finally drying the titanium sponge. According to the method, the high-chlorine titanium sponge product produced by adopting the reduction-distillation method is washed by acid and water, dried and the like, thereby the content of the chlorine impurity in the titanium sponge is reduced. Simultaneously, the contents of other impurities are not affected, thereby the purpose of increasing the product grade is realized. Compared with the traditional remelting technology, the technology method has the advantages that the contents of other purities of the product are not increased, a reduction-distillation production device is not occupied, the power consumption is not increased, the cost is low and the benefit is great.
Description
One, technical field
The invention belongs to the titanium metallurgical technology field, be specifically related to the method that a kind of pickling reduces chlorine impurity in the Titanium Sponge 40-60 mesh.
Two, background technology
In the Titanium Sponge 40-60 mesh Industrial processes, magnesium reduction---distillation method is occupied an leading position.This method is that titanium ore is produced smart titanium tetrachloride through enrichment-chlorination-refining, under the protection atmosphere of rare gas element argon gas, add magnesium reduction and produce Titanium Sponge 40-60 mesh, after remove magnesium and magnesium chloride impurity through vacuum distilling, handle the back and form the Titanium Sponge 40-60 mesh product.Vacuum distilling is with Mg and MgCl in the reduzate (titanium that promptly has been shaped sticks together)
2Impurity according to they at high temperature vp differ greatly, separation factor is big, and it is carried out rectifying separation, reaches the purpose that Titanium Sponge 40-60 mesh is purified.Along with improving constantly of the single furnace output of integrated process, associating stove production unit maximizes day by day, and the impurity cl content has been controlled to critical restraining factors in the Titanium Sponge 40-60 mesh.In addition, the chlorine element has pollution to vacuum system when ingot casting, influence service life of equipment, also can impact the product of other batch.
At present, Titanium Sponge 40-60 mesh production mainly leans on the vacuum distilling mode that the distillation of the magnesium chloride in the product is purified, but portioned product is because problems such as equipment and operations, and cl content is higher in the Titanium Sponge 40-60 mesh, can't be up to standard.Usually adopt the mode of melting down that product is purified once more, in the hope of reducing product chlorine foreign matter content.But owing to need a large amount of power consumptions; And other foreign matter content of product (oxygen, nitrogen, iron etc.) there is influence largely, when reducing cl content, has increased the content of other impurity; Can not play the substantial effect that improves product hierarchy, improper on the economic benefit.
Three, summary of the invention
The purpose of this invention is to provide the method that a kind of pickling reduces chlorine impurity in the Titanium Sponge 40-60 mesh, can effectively reduce chlorine foreign matter content in the high chlorine Titanium Sponge 40-60 mesh, do not increase the content of other impurity, thereby improve the grade of product.
For realizing above-mentioned purpose; The technical scheme that the present invention adopts is: get reduction---high chlorine Titanium Sponge 40-60 mesh and mass concentration that distillation method is produced are the hydrochloric acid of 0.5-5%; According to Titanium Sponge 40-60 mesh: hydrochloric acid is the mass ratio of 0.7-1.2:1, and Titanium Sponge 40-60 mesh is immersed in the hydrochloric acid, and soak time is 0.5-2 days; Water with 5-7 times of hydrochloric acid volume cleans 4-6 time again, carries out drying at last and gets final product.
Above-mentioned high chlorine Titanium Sponge 40-60 mesh is meant that the chlorine foreign matter content is at the Titanium Sponge 40-60 mesh more than 0.06%.
Above-mentioned drying is meant in kiln dries, and bake out temperature is 30-150 ℃.
Above-mentioned drying is meant with pressurized air or argon gas carries out drying.
The present invention is through to reduction---the high chlorine Titanium Sponge 40-60 mesh product that distillation method is produced carries out treating processess such as pickling, washing, drying, thereby reduces chlorine foreign matter content in the Titanium Sponge 40-60 mesh.Simultaneously, other foreign matter content is not had influence, realize improving the purpose of product hierarchy.The technological advantage that melts down that this process method is more traditional is: do not increase other foreign matter content of product, do not take reduction-distillation production unit, do not increase power consumption, cost is low, and income is big.
[0010] four, embodiment
Embodiment one:
Get reduction---chlorine foreign matter content that distillation method is produced Titanium Sponge 40-60 mesh and the mass concentration more than 0.06% is 1% hydrochloric acid; According to Titanium Sponge 40-60 mesh: hydrochloric acid is 1.2: 1 mass ratio; Titanium Sponge 40-60 mesh is immersed in the hydrochloric acid; Soak time is 1 day, and the water with 5-7 times of hydrochloric acid volume cleans 4-6 time again, carries out drying at last.The forward and backward analytical test index of sample preparation is following:
Embodiment two:
Get reduction---chlorine foreign matter content that distillation method is produced Titanium Sponge 40-60 mesh and the mass concentration more than 0.06% is 5% hydrochloric acid; According to Titanium Sponge 40-60 mesh: hydrochloric acid is 0.7: 1 mass ratio; Titanium Sponge 40-60 mesh is immersed in the hydrochloric acid; Soak time is 2 days, and the water with 5-7 times of hydrochloric acid volume cleans 4-6 time again, carries out drying at last.The forward and backward analytical test index of sample preparation is following:
Embodiment three:
Get reduction---chlorine foreign matter content that distillation method is produced Titanium Sponge 40-60 mesh and the mass concentration more than 0.06% is 2% hydrochloric acid; According to Titanium Sponge 40-60 mesh: hydrochloric acid is 0.9: 1 mass ratio; Titanium Sponge 40-60 mesh is immersed in the hydrochloric acid; Soak time is 1 day, and the water with 5-7 times of hydrochloric acid volume cleans 4-6 time again, carries out drying at last.The forward and backward analytical test index of sample preparation is following:
Can know from top three forms; The chlorine foreign matter content of the product after handling through the inventive method all has obvious reduction, minimumly reduces to 0.045% (embodiment three), and other foreign matter content and hardness number do not have considerable change; Product hierarchy rises to 2 grades by 5 grades, and quality product significantly promotes.
