Abstract
The present invention builds for a kind of castable with repairing ladle and builds electric induction furnace fire door to protect the mechanism of fire door.Directly toasted because being not easy by the molten iron melted the fire door part of electric induction furnace, the crystallization temperature of quartz sand lining material is lower than middle and lower part, in addition slagging-off charging is often subject to mechanical failure in use, after being built with castable and building converter mouth ring, castable, which is not required to high-temperature baking, to be solidified at normal temperatures, it can just fire door is increased the service life, energy normal use can be not necessary to repair during a furnace life.
Description
Technical field
Foundary industry melts the new material structure of molten iron electric induction furnace fire door.
Background technology
Foundary industry is mould will to be poured into after metal molten, cools down a kind of process of aftershaping.Fusing metal one
As be all to use furnace cupola or electric induction furnace, now using electric induction furnace it is commonplace.Electric induction furnace furnace chamber and induction coil it
Between have one layer of furnace lining, be that quartz sand mixing boric acid tamping in body of heater is solid, be then electrified to heat up, through quartz sand after a while
Furnace lining is heated, and gradually solidification puts into normal use for its crystallization change.And the induction coil of electric furnace be in the middle and lower part of furnace chamber, it is close
Fire door top is not easy to be dried refining by the high temperature of molten iron with regard to no coil on furnace chamber top, and quartz sand lining curing degree does not just have
Middle and lower part is high, the easy slagging in fire door position in addition, in the process that removes the gred and feed by mechanical damage also than more serious, so this position
Furnace lining be very easy to damage.Often to be built 4-5 times again in a furnace life, must have a power failure during build sky molten iron, then
It is re-energised fusing molten iron.
The content of the invention
The purpose of the present invention is the patching material brickwork close to the circle ladle of fire door part one in electric induction furnace, can be normal
Temperature is lower to be solidified, and can reach need not carry out blowing out repairing in a furnace life, only be changed simultaneously when building furnace lining again.
The technical scheme is that a kind of castable with repairing ladle, which is built, builds electric furnace fire door to protect the knot of fire door
Structure.At 200 height of the Induction Furnace liner top by fire door, include converter nose for one section in the cast of furnace lining position with bag castable is repaiied
New furnace lining.
The distinguishing feature of the present invention is that castable can solidify at normal temperatures, and slagging-off or charging in use will not cause to damage
Bad, in a furnace life need not carry out blowing out repaiies lining.
Described castable is KLJ-75A castables.
Brief description of the drawings
The burner hearth sectional view of Fig. 1 electric induction furnaces.
Brief description of the drawings：1st, quartz sand lining；2nd, castable fire door；3rd, converter nose；4th, furnace chamber；5th, induction coil；6th, insulation material
Material.
Embodiment
A kind of castable with repairing ladle, which is built, builds electric furnace fire door to protect the structure of fire door.In electric induction furnace quartz sand
Locate to include the new fire door of converter nose 3 with repairing bag castable and enclose in furnace lining position cast one by 200 height of fire door in the top of lining stove 1
2。
Claims (1)
1. a kind of castable with repairing ladle, which is built, builds electric furnace fire door to protect the structure of fire door, it is characterized in that：In induced electricity
The top of stove quartz sand lining is located to be enclosed with repairing bag castable and pour into a mould one in furnace lining position by 200 height of fire door, including converter nose
New fire door.
