Description

TECHNICAL FIELD

[0001] The utility model relates to the whole casting technology field of blast furnace taphole clay pot, concretely is a kind of construction structure of blast furnace taphole clay pot whole casting. BACKGROUND

[0002] Blast furnace smelting is to reduce the iron ore into liquid molten iron (not dissolved in the part of molten iron becomes slag) using coke (partly replaced by coal powder, natural gas, etc.), and the generated molten iron and slag are discharged through the iron hole channel, which is located at the lower edge of the hearth, mostly circular straight hole, mainly composed of iron hole frame, protection plate, iron hole protection brick, clay pot, iron flow channel and mud bag. The service performance and maintenance of the iron flow channel directly determine the service life of the blast furnace due to the scouring and chemical erosion of the slag and iron. In recent years, the investigation of the damage of the blast furnace hearth at home and abroad also shows that almost all the damage is around the taphole and its lower part, mainly due to the more severe working conditions and more susceptible to erosion around the taphole than other parts of the hearth. The taphole clay pot is the joint surface of the corresponding plugging equipment - mud gun, and the clay pot of the blast furnace is inclined downward by 16.2°. The fired refractory clay forms a mud bag in the iron hole to protect the inner lining of the blast furnace hearth, and bears a mud pressure of 60MPa when plugging, which is an important process for the long service life of the blast furnace. Therefore, the clay pot is an important part of the long service life of the blast furnace. It is made of refractory material, and the outer layer is a protection brick, which mainly prevents the scouring of slag and iron on the iron hole, and ensures the sealing of the mud gun and the mud pot surface when plugging to prolong the service life of the iron hole.

[0003] The existing construction structure of the whole casting of the blast furnace taphole clay pot is not convenient for fixing the clay pot, which causes the clay pot to fall off during construction, is not convenient to use, and the existing construction structure of the whole casting of the blast furnace taphole clay pot is not convenient for limiting, which causes the clay pot to loosen under its own gravity, and has poor practicability.
