Abstract
The utility model belongs to the seal structure of an electric furnace water-cooling seal ring and an electric furnace water-cooling lid, and particularly relates to an electrode hole brick with a gas seal device. The electrode hole brick is characterized in that the upper end of a round pipe type electrode hole brick is provided with a circular barricade; a circular gas supply pipe is arranged in the circular barricade; gas spray pipes uniformly arranged on the inner side wall of the gas supply pipe are respectively communicated with the inner wall of the round pipe of the electrode hole brick; a gas inlet pipe connected with the circular gas supply pipe is arranged on the top face of the circular barricade of the electrode brick hole. The electrode hole brick is rational in structure, has a good effect of sealing the electrode holes of the electric furnace water-cooling lid, and is capable of reducing the loss of heat in an electric furnace, protecting the environment and reducing the electricity consumption caused by smelting; due to convenience in installation and replacement, the labor intensity of staff can be lowered.
Description
Technical field
The utility model belongs to the hermetically-sealed construction of electric furnace water-cooling sealing ring and water-cooling furnace cover of electric furnace, particularly a kind of Electrode hole brick with air seal set.
Background technology
Electrode hole brick is mainly used in the sealing of electric furnace water-cooling sealing ring and water-cooling furnace cover of electric furnace electrode hole.The Main Function of electrode hole sealing brick: 1., for the sealing of the furnace lid electrode holes such as electric furnace, LF stove and water-cooled electrode seal ring, reduce to greatest extent the gap between electrode and electrode hole, prevent that furnace heat from overflowing in a large number.2. play insulating effect.Once electrode directly contacts with water cooled cover and water cooled seal circle during electric furnace smelting, will between arcing, burn out water-cooling furnace cover of electric furnace or electrode water-cooled sealing ring, cause leakage accident.
By the material of Electrode hole brick, be now High-Alumina, Electrode hole brick be shaped as wedge shape.During use, at the electrode hole of water-cooling furnace cover of electric furnace, build into Electrode hole brick by laying bricks or stones an annular around.
Due to the electric furnace of different capabilities, all electrode diameters are different.With the Electrode hole brick of sesame oil, build into suitable electrode hole by laying bricks or stones and be not easy.It is excessive that electrode hole is built by laying bricks or stones, and sealing effectiveness is poor, and the amount of heat in electric furnace can scatter and disappear from electrode hole; It is too small that electrode hole is built by laying bricks or stones, and Electrode hole brick will directly block main electrode, affects the operation up and down of electrode.Like this some results finally cause electrode and the direct gap of Electrode hole brick excessive, sealing effectiveness is bad, has both affected environmental protection, making again to smelt power consumption obviously increases.
Summary of the invention
The purpose of this utility model is to provide a kind of Electrode hole brick with air seal set; it is rational in infrastructure; good sealing effect to water-cooling furnace cover of electric furnace electrode hole; reduce escaping of electric furnace heat; protection of the environment; reduce melting electric consumption, and install and change easily, can reduce worker's labour intensity.
The purpose of this utility model is achieved in that a kind of Electrode hole brick with air seal set, its upper end of tubular Electrode hole brick is provided with annular gear platform, in annular gear platform, annular air supply pipe is being set, on the tube wall of the inner side of air supply pipe, the uniform air jet pipe arranging is communicated with the round tube inner wall of Electrode hole brick respectively, on Electrode hole brick annulus gear countertop, the air inlet pipe being connected with annular air supply pipe is being set.
While using the utility model, before electric furnace smelting power transmission, with common fire clay, as binding agent, the utility model Electrode hole brick is mounted in the electrode hole of water-cooling furnace cover of electric furnace or electrode water-cooled sealing ring.Connect sealing gland gas.Gas is Xue Yong argon gas or nitrogen according to circumstances, and the pressure of medium is controlled and is as the criterion with the hot flue gas that can block in stove, and pressure is controlled between 10-30MPa conventionally.
The good effect that the utility model produces:
(1) due to air seal set, can thoroughly block escaping of the interior heat of circuit, protection of the environment,
Reduce melting electric consumption.
(2) Electrode hole brick of air seal set is installed and changes very convenient, has reduced worker's labour intensity.
The utility model is rational in infrastructure, the good sealing effect to water-cooling furnace cover of electric furnace electrode hole, and the escaping of heat in less circuit, protection of the environment, has reduced melting electric consumption, and installs and change easily, has reduced worker's labour intensity.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described, Fig. 1 is sectional structure schematic diagram of the present utility model, the plan structure schematic diagram that Fig. 2 is Fig. 1.
