Abstract

A method to produce a series of ferrotitanium by smelting the titanium material in Panxi area. The technology steps are as following: the titanium material in Panxi area, calcareous metallurgy accessories and calcium-sodium treatment reagent will be delivered into the revolving burner, they will be warm-up fast, and then will be delivered into blendor by connecting barn to be uniformly mixed. And then aluminium, iron system material, auxiliary reducers and potassium chlorate will be orderly added in from the batch bin, when the material and the auxiliary material in the blendor have been uniformly mixed, they will drop into the smelting furnace, which has been warmed up, by the connecting barn, the igniter will be added in, and the inhibiting agent will be added when the reaction get over for about 2-3 minutes, they will be cooled for 20-40h, and at last the residue and the ferrotitanium will be separated. The ferrotitanium product will enter warehouse after being checked and paclaged. The material source of this patent is assured, and the production technology is on the safe side, the product quality of the ferrotitanium made by it is stable, and it fulfills the different needs of all kinds of steel industry, so it the myth that the Panxi vanadium-titinium magnetite can not produce high ferrotitanium because the impurity of it is high, and it fills up the blank in our country.

Description

technical field [0001] The invention relates to a ferroalloy smelting method, specifically, the invention relates to a method for producing a series of ferro-titanium alloys by smelting titanium raw materials in Panxi area. Background technique [0002] Titanium is an important alloying element and deep deoxidation additive in steel production, known as the "third metal". Titanium can improve the structure of steel, improve the performance of steel, and increase the wear resistance and tensile strength of steel. Ferro-titanium is the first choice for the production of chain steel, anchor chain, shipbuilding steel, stainless steel, welding rods, electronics, and military products. important raw material. Due to the strong combination of titanium and oxygen and high melting point under high temperature conditions, if titanium metal is directly added in the iron and steel smelting process, not only the yield is low, but also the waste is serious and the cost is increased. It m...
