Abstract
The utility model belongs to the technical field of blast furnace maintenance and relates to a device capable of preventing gas leaking out of a cooling plate. The device capable of preventing gas leaking out of a cooling plate is a long round ring. An inner edge hole of the long round ring is composed of a rectangle which has the length of 480mm and the width of 120mm and two semi-rounds which have the radius of 60mm per semi-round. The outer edge of the long round ring is composed of a rectangle which has the length of 480mm and the width of 300mm and two semi-rounds which have the radius of 150mm per semi-round. The back of the long round ring is provided with a flange which has the height of 50mm and the width of 3mm. The device capable of preventing gas leaking out of the cooling plate is welded between a stove casing and a protective sheathe and can prevent the gas from leaking by seal.
Description
Technical field:
The utility model belongs to blast furnace maintenance field, is specifically related to a kind of leak device of coal gas of cooling plate that prevents.
Background technology:
4350m
3The bosh of blast furnace, furnace bosh and shaft middle and lower part are equipped with copper cooling plate, and copper cooling plate is connected with furnace shell through sheath, and copper cooling plate inside is built refractory materials by laying bricks or stones.
Blast furnace is after blow-on moves several years; The anti-material of blast furnace stack is wearing and tearing or damage mostly, causes the cooling apparatus of blast furnace and furnace shell to expose among coal gas of high temperature and furnace charge, along with the fluctuation of the working of a furnace; Cooling plate also can fluctuate; Cause the weld cracking between cooling plate sheath and furnace shell, coal gas leaks thereupon, brings difficulty for the safe and stable operation of blast furnace.
The way of handling the problems referred to above generally is to weld the leak position, but sees that from the situation at scene effect is undesirable.
Summary of the invention
The utility model provides and can either seal coal gas, prevents gas leak, can alleviate a kind of leak device of coal gas of cooling plate that prevents of expansible again.
The technical scheme of the utility model:
The utility model is formed by the Q235 steel; It is characterized in that it is a Long Circle ring; The interior marginal pore of Long Circle ring be that 480mm, width are that the rectangle of 120mm and semicircle that two radiuses are 60mm are formed by a length; Length of the outer cause of Long Circle ring is that 480mm, width are rectangle and two semicircle compositions that radius is 150mm of 300mm, and the back side of Long Circle ring is provided with a circle flange, and the height of flange is that 50mm, width are 3mm.
The utility model is welded between furnace shell and the sheath, can seal coal gas, anti-heads.
