Abstract
The present invention relates to a quartz sand application technology for lining of induction furnace. It is characterized by that said application technology is composed of building furnace, drying furnace, burning furnace, protecting furnace and repairing furnace. The adoption of said invented furnace lining can greatly prolong the service life of the induction furnace, reduce cost, raise working efficiency, and the furnace life can be prolonged by more than 45 days, and the furnace time can be raised to above 300-500 furnace times.
Description
The present invention relates to make furnace lining on a kind of steel-making electric induction furnace and use technology with quartz sand.
The electric induction furnace temperature-resistant material adopts refractory brick mostly in the prior art, but the furnace wall is thicker, cumbersome and heatproof weak effect on the technology, and the use cost height, the life cycle of stove is very short.The someone adopts quartz sand to make electric induction furnace furnace lining temperature-resistant material at present, but owing to use inappropriate technology, furnace life is also very short, is easy to generate to wear the stove phenomenon.
Purpose of the present invention aims to provide a kind of furnace lining sand that can prolong electric induction furnace furnace life and uses technology.
Technical scheme of the present invention adopts the following step to finish:
(1) brickwork → (2) baker → (3) are burnt stove, are protected stove and fettling
The course of work of the present invention is described in detail in detail below:
One, furnace building process:
1, furnace lining sand humidity allotment: moisture content 2%～3% is advisable.
2, water mixing is sprayed and is evenly stirred, if moisture inhomogeneous, has indiscoverable shrinkage crack phenomenon after the body of heater oven dry, and this can cause wears stove.
3, brickwork must the branch multilayer be built tightly, bed thickness 3～5cm, and more then heat insulation effect is better.
Two, roast technic:
1, furnace drying time: the high and low used asynchronism(-nization) of baker stove water-containing rate, baker moisture content height is directly proportional with furnace drying time.
2, baker is a standard with stove dry sand moisture content, and the not dried heat of baker moisture content uses just few.
Three, burn stove, guarantor's stove and fettling technology:
1, body of heater oven dry dry after, enter add the steel blow-on before, should add an amount of sheet glass according to the size of stove, notice that burning first stove does not use the bloom that gets rusty, and notes protecting body of heater when reinforced.
2, protect stove: every stove adds an amount of sheet glass, and sheet glass can protect body of heater durable, also can clear up waste steel slag.
3, fettling: when the furnace wall burns can not re-use soon the time, in time take the fettling measure, the furnace wall can be repaired continuously.
The present invention can improve the service life of electric induction furnace, and furnace life was prolonged more than 45 days, more than heat 300～500 heats, can save cost, improves work efficiency.
Claims (1)
1, a kind of electric induction furnace furnace lining quartz sand uses technology, it is characterized in that:
A, furnace building process: furnace lining quartz sand moisture content is 2%～3% and evenly stirs back branch multilayer and build tightly bed thickness 3～5cm.
B, roast technic: stove water-containing rate height is directly proportional with furnace drying time.
C, burning stove, guarantor's stove and fettling technology: add an amount of glass before adding the steel blow-on in the stove.
