Combined stove especially for ferrotitanium smelting

Abstract

The invention relates to a special combined furnace used for ferrotitanium smelting. The furnace has a combined detachable structure, comprising a furnace cylinder 1 and a furnace base 2 which can be conveniently combined and disassembled. The furnace cylinder 1 consists of a cylinder outer casing 3, a furnace lining block 4 and a combined gemel 5. A hook 6 is arranged on the cylinder outer casing 3, and a furnace liner is formed by combing the furnace lining block 4 and the combined gemel 5. The furnace cylinder 1 comprises an upper furnace cylinder 11 and a lower furnace cylinder 12. A slag draining outlet 111 is arranged on the upper furnace cylinder 11 and a connecting flange 121 is arranged around the bottom of the lower furnace cylinder 12. An inward sliding transition ring 122 is arranged on the inner wall of the lower furnace cylinder 12 on the jointing part with the furnace seat 2 which consists of a furnace base casing 21 and a base 22, and a tightening fastener 211 is arranged on the furnace seat casing 21. The lower furnace cylinder 12 is fixed on the furnace base 2 through the connecting flange 121 at the bottom and the tightening fastener 211, and the upper furnace cylinder 11 is arranged on the lower furnace cylinder 12. The invention is a non-fixed split structure and the position can be pulled and changed for a recycle use. The invention has the advantages that the structure is simple; the operation is convenient; the disassembling, maintenance and replacement are convenient.

Description

technical field [0001] The invention relates to metal smelting equipment, in particular to a combined furnace specially used for smelting ferrotitanium. Background technique [0002] At present, in the production of domestic metallurgical industry, the methods used for the production of ferro-titanium alloy mainly include the aluminothermic method, the electric furnace remelting method and the induction electric furnace remelting and blending method. The structural properties of the smelting equipment selected by these three methods are as follows : [0003] The aluminothermic method is a smelting method outside the furnace. The smelting equipment used is a simple magnesia furnace. The furnace body is composed of a furnace tube and a magnesia nest. The structure is simple and it is a fixed production equipment. The disadvantage of this method is that the price of reducing agent aluminum is too high, resulting in too high production cost, and it is rarely used by production ...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is that the price of reducing agent aluminum is too high, resulting in high production costs, and it is rarely used by production enterprises.

The disadvantage of this method is that the price of titanium waste is too high, the overall production cost is too high, resulting in a narrow market application, and the liquid titanium ferroalloy is partially in contact with the air when it comes out of the furnace, and the quality of the product has been damaged. This method is not suitable for industrial production.

The disadvantage of this method is that the production cost is high and the yield is low.

[0006] In addition, the current domestic production of ferro-titanium uses fixed equipment that is not professional enough, and most of them are general-purpose equipment, which cannot fully meet the special technical requirements of ferro-titanium production, thus limiting the production cost and output of ferro-titanium, and thus affecting domestic The use of ferro-titanium alloys in related industries has curbed the normal development of the titanium industry
