Example Embodiment

[0020] Now, the method for smelting titanium slag in an electric furnace according to the present invention will be described in detail.

[0021] The method for smelting titanium slag in an electric furnace according to the present invention includes the following steps:

[0022] (1) Mix ilmenite and reducing agent to prepare charge;

[0023] (2) Add charge to the electric furnace;

[0024] (3) Titanium smelting slag, in which the power of the electric furnace during the smelting process is 12MV·A~30MV·A;

[0025] (4) Slag and iron are tapped.

[0026] According to the method for smelting titanium slag in an electric furnace of the present invention, ilmenite is powder, and TiO in the ilmenite 2 The weight content of the reducing agent is greater than or equal to 44% (preferably 44% to 47%), the reducing agent is one of granular coke, anthracite, and petroleum coke. The particle size of the reducing agent is 1mm-15mm and the carbon content is not low. Less than 80%. The compoundin...

Abstract

The invention provides a method for smelting titanium slag by an electric stove. The method comprises the following steps: titanic iron and a reducing agent are mixed to prepare charging materials which are added into the electric stove; the titanium slag is smelted, the power of the electric stove is between 12MV.A and 30MV.A in the smelting process; and the slag is discharged, and the iron is discharged.

Description

technical field [0001] The invention relates to a method for smelting titanium slag in an electric furnace, more specifically, to a method for smelting titanium slag in a high-power electric furnace. Background technique [0002] The electric furnace method for smelting titanium slag is to use reducing agents (such as anthracite, petroleum coke, coke, etc.) to selectively reduce ilmenite to remove most of the iron, enrich the titanium into the slag and make the iron into molten iron, thereby producing titanium slag And pig iron (semi-steel) two products. The production process of this method is simple, mature, short process, high efficiency, the iron produced can be directly used, no solid and liquid waste is produced, the heat and gas generated by the electric furnace can be recycled, no pollution to the environment, and the titanium slag product has special characteristics. The process performance is beyond the reach of other titanium-rich materials. [0003] The low-pow...
