Abstract

The invention discloses a method for smelting and preparing series ferrotitanium from high-phosphorus, sulfur and titanium raw materials in pan-xi region, which comprises the following steps: adding titanium raw materials in the pan-xi region and 20 to 40 percent of iron-containing materials into a revolving furnace, quickly heating the materials for 20 to 25 minutes until the temperature is between 700 and 850 DEG C, and sending the materials into a mixer through a connecting bin for full and uniform mixing; adding calcium metallurgical auxiliary materials, a calcium-sodium finishing agent, metal aluminum, an auxiliary reducer and potassium chlorate into a proportioning bin in turn, and uniformly mixing the raw materials and the auxiliary materials in the mixer; unloading the mixed materials into a smelting furnace which is preheated to a temperature of between 150 and 300 DEG C and an elevated stock bin through the connecting bin, and smelting the mixed materials according to lower ignition technology; adding refined materials and a retarder after the reaction is over, and cooling the mixed materials for 48 to 80 hours; and finally separating slag and the ferrotitanium, and checking, packaging and warehousing ferrotitanium products. The method has stable sources of raw materials and safe and reliable manufacturing technique, and the prepared ferrotitanium series products have stable quality, so that the method breaks through the myth that the ferrotitanium can not be produced due to high content of impurities in the titanium-containing raw materials in the pan-xi region and makes up for the blank in China.

Description

technical field [0001] The invention relates to a method for smelting ferro-titanium alloys, in particular to a method for preparing a series of ferro-titanium alloys by smelting high-phosphorus and sulfur-containing titanium raw materials in Panxi area. Background technique [0002] Ferro-titanium is an important alloying raw material and deep deoxidation additive in steel production, and titanium is called "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 alloy is an important raw material for the production of chain steel, anchor chain steel, shipbuilding steel, stainless steel, welding electrodes, electronics, and military products. Due to the strong combination of titanium and oxygen and light specific gravity under high temperature conditions, if titanium metal is directly added in the iron and steel smelting process, not only the burning loss...
