Abstract
The utility model discloses a kind of electric induction furnace structure, its be installed with the top of body of heater by high temperature resistant, high intensity, high tenacity magnesium iron made of pressing plate, the pressing plate internal diameter is consistent with the internal diameter of furnace lining material, and external diameter is consistent with body of heater external diameter；Rectangle tooth-like recesses are uniformly arranged at the inner ring of pressing plate.Described electric induction furnace structure, restraining force is provided by pressing plate, a certain degree of can suppress expanding with heat and contract with cold for burner hearth and furnace lining, so as to be effectively protected body of heater and furnace lining, extend the service life of electric furnace liner material, improve its security.
Description
Technical field:
It the utility model is related to the structure of electric induction furnace.
Background technology：
Electric induction furnace is at present and the environment-friendly type sensing of low-loss and energy-saving to metal material efficiency of heating surface highest, fastest
Firing equipment, it is used widely in Castiron Melting production.
Existing electric induction furnace, its usual furnace lining material are acid quartz sand, the furnace lining material during baker with
The increase of temperature, its expansion can change therewith, and especially it can be changed at 870 DEG C from α quartz to α phosphorus quartz ppolymorphism,
Very big Volume Changes can occur.During molten iron high melt, in the presence of without external force, furnace lining material expands with heat and contract with cold
Effect easily allows electric induction furnace burner hearth to be formed and pulls damage, and furnace lining material is easily formed crackle simultaneously, so as to influence to sense
Electric furnace and lining durability, or even cause to wear stove accident.
Utility model content：
The defects of the utility model is intended to overcome above-mentioned prior art, provide a kind of burner hearth and furnace lining material be hardly damaged,
Use safer, the particularly longer electric induction furnace structure of furnace lining material service life.
Electric induction furnace structure described in the utility model, including body of heater and furnace lining, its be installed with body of heater top by
High temperature resistant, high intensity, high tenacity magnesium iron made of pressing plate, the pressing plate opening is in " eight " font, with electric induction furnace converter nose phase
Matching, internal diameter is consistent with the internal diameter of furnace lining material, and external diameter is consistent with body of heater external diameter；Rectangle is uniformly arranged at the inner ring of pressing plate
Tooth-like recesses.
High slight, high tenacity is installed with the top of electric induction furnace structure described in the utility model, its body of heater and furnace lining
Pressing plate, during the burner hearth thermal expansion that works at high temperature, pressing plate can provide the power of limitation burner hearth thermal expansion, when burner hearth cools, pressing plate
The power for suppressing burner hearth shrinkage can be provided again, thus it can a certain degree of generation for suppressing rising-heat contracting-cold.In addition it is equal at inner ring
Even to set rectangular tooth-like recesses, it alsos for expanding with heat and contract with cold for furnace lining and provides enough spaces, so that can effectively keep away
Exempt from the generation of furnace lining material cracking.The effective service life for extending burner hearth and furnace lining.
Brief description of the drawings：
The structural representation of Fig. 1 electric induction furnaces；
The structural representation of Fig. 2 pressing plates；
The side view of Fig. 3 pressing plates.
Embodiment：
A kind of electric induction furnace structure, such as Fig. 1, including burner hearth 1 and furnace lining 2, roof of the furnace be installed with by high temperature resistant,
High intensity, high tenacity magnesium iron made of pressing plate 3, affiliated pressing plate, such as Fig. 2, Fig. 3, opening is in " eight " font, with electric induction furnace stove
Mouth matches, and internal diameter is consistent with the internal diameter of furnace lining material, and external diameter is consistent with electric induction furnace external diameter；Uniformly set at the inner ring of pressing plate
Put rectangle tooth-like recesses 4.
The pressing plate needs to bear high temperature at work, is preferred with the ductile iron material for having some strength, can select
The QT500-10 trades mark produced the magnesium iron of high temperature resistance and high strength high tenacity by the solution strengthening effect of silicon just now.
The thickness of compressive plate is preferred with 40-50mm.
Pressing plate is tightened at the top of body of heater by the settable fastening ear 5 in the cylindrical place of pressing plate, bolt by hole through fixed ear
Top.
Fastening ear through may be configured as the structure of counterbore 6 at bolt, bolt head can hide with counterbore.
Fastening ear is preferred with three in the angle distribution of 120 degree of interval.
Can be set anti-skid bulge on the surface of pressing plate, anti-skid bulge 7 can be point-like, linear, polyline shaped, curve-like or its
Its shape.By setting anti-skid bulge to prevent blanking personnel pin from sliding, security performance is more preferably.
