Abstract

The invention relates to an upper structure of an integral protective plate body, which is characterized in that: it is made of vermicular graphite cast iron, the inner lower protective surface is in an arched structure, is connected with the coke oven head, and the refractory castable is poured at the connection gap. Sealing; the inner upper protective surface has a polygonal structure, which is connected to the coke oven head, and the connection gap is poured with refractory castables to seal; the outer protective surface has a polygonal structure, and the beam is pressed against the outer protective surface; the sealing surface has a polygonal fold line structure, which is removed with Materials Methods to obtain surface roughness. The invention has the characteristics of reasonable design, beautiful appearance, simple and compact structure, good sealing effect, easy installation and the like. It overcomes the problems of the current metallurgical industry heat recovery coke oven protective plate body: poor sealing effect, deformation of the protective plate and furnace door due to high temperature combustion, serious burning loss, frequent maintenance and replacement, resulting in environmental pollution and reduced economic benefits of enterprises.

Description

An upper structure of an integral protective plate body

technical field

The invention belongs to a heat recovery coke oven protective plate body in the metallurgical industry, relates to a protective plate suitable for a clean heat recovery coke oven, and particularly relates to an upper structure of an integral protective plate body.

Background technique

The upper part of the integral protective plate body is a part of the integral protective plate body. At present, the clean heat recovery coke oven protective plate traditionally used in the metallurgical industry in the prior art consists of an upper protective plate, a lower protective plate and a middle protective plate. The assembled structure composed of the inner and outer sides of the upper protective plate adopts an arch structure, and the contact between the outer side and the furnace door is not sealed, and the rigid furnace door is directly pressed on the protective plate. It enters at the contact with the protection plate, and burns with the coal cake at the head of the coke oven. The protection plate and the furnace door are deformed and burned seriously due to high temperature combustion. The maintenance and replacement are frequent, resulting in environmental pollution and reduced economic benefits of the enterprise.

SUMMARY OF THE INVENTION

The invention overcomes the above-mentioned defects, and aims to solve the existence of the clean heat recovery coke oven protection plate traditionally used in the metallurgical industry: the sealing effect is poor, the outside air enters from the contact point between the oven door and the protection plate, and the coke oven head When the coal cake is burned, the protective plate and the furnace door are deformed and damaged due to high temperature combustion, and the maintenance and replacement are frequent, resulting in environmental pollution and reduced economic benefits of the enterprise.

The upper structure of the integral protection plate body of the present invention is characterized in that: the inner lower protection surface is made of vermicular graphite cast iron to form an arch structure, which is connected with the coke oven head, and the refractory castable is poured at the connection gap to seal; The protective surface has a polygonal structure and is connected with the coke oven head, and the connection gap is poured with refractory castables for sealing; the outer protective surface is in a polygonal structure, and the beam is pressed against the outer protective surface; the sealing surface is in a polygonal polyline structure.

The invention has the characteristics of reasonable design, beautiful appearance, simple and compact structure, good sealing effect, easy installation and the like. It overcomes the problems of the current metallurgical industry heat recovery coke oven protective plate body: poor sealing effect, deformation of the protective plate and furnace door due to high temperature combustion, serious burning loss, frequent maintenance and replacement, resulting in environmental pollution and reduced economic benefits of enterprises.

Detailed ways

The upper structure of the integral protective plate body of the present invention is an improvement to the design of the heat recovery coke oven protective plate body.

1 to 3, the upper structure of the integral protective plate body of the present invention is made of vermicular graphite cast iron to make the inner lower protective surface 1 in an arched structure, which is connected with the coke oven head, and the refractory castable is poured at the connection gap. Sealing; the inner upper protective surface 2 has a polygonal structure, which is connected to the coke oven head, and the connection gap is poured with refractory castable to seal; the outer protective surface 3 adopts a polygonal structure, and the beam is pressed on the outer protective surface; the sealing surface 4 adopts a polygonal polyline structure , The surface roughness is obtained by removing the material, and the spring knife edge of the furnace door is directly pressed on the sealing surface, and the sealing is tight and the sealing effect is good.

The upper structure of the integral protective plate body of the present invention has the characteristics of reasonable design, beautiful appearance, simple and compact structure, good sealing effect, easy installation and the like. Overcome the current metallurgical industry heat recovery coke oven protective plate body, there are: poor sealing effect, the outside air enters from the contact between the furnace door and the protective plate, and the coal cake at the coke oven head burns, and the protective plate and the furnace door are damaged due to high temperature combustion. Deformation, serious burn damage, frequent maintenance and replacement, resulting in environmental pollution and reduced economic benefits of enterprises and other problems.
