Description
Technical field
The invention belongs to smelting equipment technical field, i.e., a kind of mineral hot furnace open hearth lid.
Background technology
In the prior art, mineral hot furnace is also known as electric-arc furnace or resistance electric furnace.It is mainly used in reducing and smelting ore, carbonaceous
The raw material such as reducing agent and solvent.Mineral hot furnace is a kind of huge industrial furnace of power consumption.It is main by furnace shell, it is bell, furnace lining, short
Net, water-cooling system, smoke evacuation system, dust pelletizing system, electrode shell, Electrode Fluctuation and jacking system, loading and unloading system, holder burn
Wear device, hydraulic system, the composition such as ore heat furnace transformer and various electric equipments.
Traditional bell is very poor to CO recovering effects in sealed furnace, and bell is toasted by flare in stove for a long time, bell
Deformation, many coming off with bell refractory material, sealing is destroyed, the phenomenon such as leak.Cause bell sealing because bell is deformed
Destroyed, air enters in stove, is chemically reacted with flue gas, CO contents in its inner flue gas of the stove is drastically declined, furnace temperature liter
It is high.When more having the working of a furnace bad, inner flue gas of the stove is largely overflowed, and severe safety accident occurs, and loss is caused to enterprise.
Other furnace cover structures of in the market, to ensure bell non-deformability, bell design is complicated, and furnace inner space is larger, stove
CO sustained responses under furnace high-temperature environment generate CO2 in lid flue gas, increase the temperature in furnace, increase each part of bell
Pressure, reduces the CO rate of recovery.
The content of the invention
It is an object of the invention to provide a kind of mineral hot furnace open hearth lid, traditional bell defect, bell long lifespan, sealing are solved
It will not reliably fail, it is ensured that CO concentration in flue gas will not be because of structure and seal break-off generation consumption.
The technical scheme is that：A kind of mineral hot furnace open hearth lid, it is characterised in that including a central cover, it is multiple along circle
Weekly interval is connected in the girder inner end of radiation profiles with central cover, connection of being insulated between girder outer end and furnace shell；Below girder
Have on supporting plate, supporting plate to have to be covered with steel plate, steel plate on fire resisting material module, fire resisting material module and be fixedly connected with interval circular row
Multiple auxiliary beams of cloth, have certain space, shaft-like securing member are passed through between girder and each auxiliary beam between girder and auxiliary beam
Insulating suspension is connected.
In such scheme,
Main beam design is into arch-type structure.
Connection of being insulated between girder outer end and furnace shell is fastenedly connected using flanged plate and bolt, and between flanged plate,
Insulation board, felt pad are lined with nut pad.
Between girder and each auxiliary beam by the connection of shaft-like securing member insulating suspension be using girder upper flange plate with
Be bolted connection between shaft-like upper end backing plate, and between flanged plate, insulation board, felt pad are lined with nut pad.
Advantage of the present invention：
1. many girder load-carrying construction are used, i.e., by main beam design into arch-type structure.Auxiliary beam is hanging on girder, by refractory material
It is hanging on auxiliary beam, girder is not contacted with furnace high-temperature area, while multilayer hanging circular configuration reduces the conduction of in-furnace temperature, Du
Absolutely deformation is produced because girder is heated.
2. reducing stove internal upper part free space, the reduction of flue gas reserves greatly reduces in coal gas CO in furnace high-temperature environment
Lower sustained response generates CO2Possibility.Reclaimed for mineral heating furnace flue, carry out secondary utilize and create prerequisite, improve coal gas
The middle CO rate of recovery.
3. encapsulant selects light material.Heat-insulating capability is strong, good sealing effect, is applicable the complicated position of the hot stove of various stoves
Sealing.
4. tremie pipe enters the expects pipe that stove section employs resistance to heat treatment, shorten tremie pipe and enter furnace length, extension expects pipe uses the longevity
Life.Reduce cost of manufacture.
5. new open hearth lid does not set water flowing, the accident of bell leak generation is prevented completely.In cost, energy-conservation, safety, ring
There is more significant breakthrough in terms of guarantor.
Embodiments of the present invention are described in further detail below in conjunction with accompanying drawing.
