Description
Technical field
The present invention relates to a kind of steel smelting equipment, specially a kind of regenerative gas fire coal scrap melting stove.
Background technology
With the development of Chinese national economy, equipment made of great deal of steel has gradually arrived the superseded time limit, especially scraps
The steel scrap that automobile and mechanical equipment and mechanical processing industry generate is more and more.Such as various used facilities, steel construction piece,
Locomotive, vehicle, rail, automobile, ship, tool, the apparatus of " scrapping " etc..Annual steel scrap yield can be accounted in industrially developed country
To the 25~30% of steel total output.Make full use of steel scrap be also reduce pollution, reduce steel ore smelting amount important channel it
One.Fully to efficiently use steel scrap, development mini-mill steelmaking is the inexorable trend of all advanced industrial countries.But normal steel mill
Converter is limited using the ability of steel scrap, of high cost using electric furnace steel, and investment is big.Common coal-fired, combustion gas cupola furnace can not melt
Steel scrap can only change iron.Because the fusing point of iron only has 1230 DEG C, 1520 DEG C of the fusing point of steel.I.e. enabled melt portions steel scrap, also because
Carbon containing height, and become molten iron, increase the cost of steelmaking oxygen blowing decarburization.
Invention content
The present invention provides a kind of regenerative gas fire coal scrap melting stove to solve the problems, such as smelting scrap steel.
The technical scheme is that a kind of regenerative gas fire coal scrap melting stove, including pedestal, furnace body, charging are logical
Road, the pedestal are located at below furnace body, and loading channel is set to above furnace body, and loading channel is connected to furnace body, and furnace body has
Tapping hole, furnace body side are equipped with heating device, and heating device is connected to by burner spout with furnace body, are arranged before burner spout high
Press electronic ignition device.
Heating device is externally provided with and sets heat storage in the regenerative chamber of burner spout connection, regenerative chamber, and accumulation of heat is set in regenerative chamber
Room cover plate, regenerative chamber have blast main, smoke explorer, blast main and connect air flue gas switching valve with smoke explorer, empty
Gas flue gas switching valve is connected to regenerative chamber by expansion joint.
Operation principle：By positioned at furnace body side heat device in stove and the steel scrap of loading channel lower end heats,
Make its fusing.The burner of combustion medium can individually use combustion gas, fire coal or joint fuel.When individually coal-fired, it is less than in furnace temperature
Before 800 DEG C, it should which companion combusts gas, or first with gas heating to 800 DEG C or more, and coal dust smooth ignition is facilitated to burn.When furnace lifting,
It is lighted a fire using high-pressure electronic burning torch, after furnace temperature is higher than 800 DEG C, burning torch is extracted, to extend the burning torch service life.After 800 DEG C, spray
The Pulverized Coal entered can be with spontaneous combustion, without igniting.The intermittent addition steel scrap of system, laser heating fusing, it is intermittent go out molten steel.This
Invention can inexpensive melting waste steel, than directly using electric furnace 400 ~ 500 yuan/ton low.
