Abstract

The utility model provides a graphite soderberg electrode casing which belongs to the field of electrode preparation technology of thermal electric furnace for mines, and aims to solve the problem that the electrode casing of the traditional self-baking electrode casing is made of sheet irons, and the electrode can be consumed ceaselessly in the production process, the iron casing is also fused in the product, thereby increasing the iron impurity, reducing the product quality and increasing cost. The utility model has a round tube electrode casing which is made of graphite or plain carbon material; the electrode casing take tubular shape, and is formed by a knock-down connection of two sections or a plurality of sections, the hollow inner is filled with electrode pastes. The utility model has the advantages of light weight and low cost; and the graphite soderberg electrode casing has conduction power of the solid graphite electrode, therefore, the utility model can save cost by fifty percent.

Description

Graphite self-baking electrode shell

The utility model relates to a kind of ore-smelting electric furnace electrode fabrication field.

The electric furnace electrode of products such as China's ore-smelting electric furnace smelting commercial silicon, alusil alloy, yellow phosphorus generally adopts graphite electrode or carbon pole at present, to satisfy the control requirement of product quality to iron tramp.But owing to costing an arm and a leg of graphite electrode, the production cost height, if adopt the cost of self-baking electrode metallurgy industry silicon electrode can descend about 50%, but because traditional self-baking electrode is that the electrode shell that adopts iron sheet to manufacture is to support molding structure, temperature constantly rises in the production smelting process, electrode paste is fusing gradually in iron-clad, volatilization, solid-state, sintering forms self-baking electrode, electrode constantly consumes and transfers iron-clad and electrode consumes at stove together and in should distinguishing in process of production, iron finally fuses in the product, and the product ferrous contaminants increases, and makes the smelting process process increase iron removal step, complex process, production cost increases synchronously.

The for a change traditional self-baking electrode shell of the purpose of this utility model adopts iron sheet to manufacture, for solving and realize a self-baking electrode iron-free difficult problem.

Self-baking electrode shell of the present utility model selects for use graphite or carbon materials to create electrode supporting structure, replaced traditional iron-clad supporting construction, particularly to satisfy the requirement of the low iron of products such as industrial silicon, alusil alloy, simultaneously, the thickness of graphite electrode shell only has about 1/10th of solid graphite electrode diameter, have the low advantage of heavy and light cost, the power of solid graphite electrode is arranged again.

As follows below in conjunction with description of drawings:

Shown in the accompanying drawing, be main member schematic diagram of the present utility model.

Shown in the accompanying drawing wherein: arthrolith China ink shell under the 1-, the 2-electrode hollow bulb packing electricity consumption utmost point is stuck with paste, the hollow joint of cover in the 3-graphite electrode shell, the black shell of the last economize on electricity of 4-.

As shown in the figure, 1,3,4 adopt screw thread to be connected together, according to producing needs linking successively.Stick into the one-piece type two-in-one self-baking electrode that becomes with (1), (3), (4) behind electrode paste (2) sintering.

The utlity model has the power of solid graphite electrode, the electrode cost only has 50% of solid graphite electrode, can save 50% cost.

Claims

1, graphite self-baking electrode shell, it is characterized in that: electrode shell is shaped as tubulose, selects graphite or carbon materials for use, and electrode shell can be formed by connecting through joint is removable by two joints or some joints.

2, graphite self-baking electrode shell according to claim 1, it is characterized in that: the termination that the every joint of electrode shell is connected with joint is shaped on internal thread, is shaped on externally threaded joint and plays interconnect function.

3, according to claim 1 and the described graphite self-baking electrode of claim 2 shell, it is characterized in that: joint is the taper of hollow waist drum, its surface is an external screw thread, and conical internal thread is correspondingly made in the termination that the every joint of electrode shell is connected with joint, and they form tapered thread and connect.
