On straddle carrier 14；
9) bundled scrap transport, feeding, preheating, the unloading, guarantor in two preheating furnace workshops 24 are carried out by above-mentioned steps circulation
Temperature and enter furnace operation.
In addition, due to the bundled scrap of bundled scrap especially thin material compacting, it is internal inevitably to contain on a small quantity
Paint and various organic components, when using conventional combustion modes, preheating furnace low-temperature prewarming band 200-400 DEG C i.e. it is gasifiable or
It evaporates and is discharged into atmosphere with flue gas by air-introduced machine, cause atmosphere pollution and environmental issue due to burning because that cannot aoxidize.To understand
The problem of certainly part bundled scrap contains organic matter, scrap steel preheating furnace use two kinds of combustion modes, and one is for without organic
The bundled scrap of object uses conventional combustion low-temperature smoke extraction mode (200 DEG C of exhaust gas temperature or so)；One is for containing organic matter
The bundled scrap of thin material, using coal gas of converter, air high temperature Two-cuff Technique combustion mode.Preheating furnace is using coal gas, the double storages of air
Heat can make the organic matter oxygen for gasifying or evaporating by improving coefficient of excess air for hot arc (800-900 DEG C of furnace temperature) in its preheating
Change and burns totally.Therefore, in the present embodiment, the 1# in a kind of production-process systems of mating converter preheating scrap briquetting
Preheating furnace body in preheating furnace workshop uses conventional combustion low-temperature smoke extraction mode, and the preheating furnace body in 2# preheating furnace workshop uses
Coal gas, air Two-cuff Technique combustion mode may be implemented the preheating production of various bundled scraps, further increases the present embodiment preheating
Different sizes, the ability of different materials bundled scrap.
Place is not described in detail for the utility model, is the well-known technique of those skilled in the art of the present technique.
