Description

Use the silicomanganese production method of rotary kiln sintered powder and hot charging ore-smelting furnace
Technical field
The present invention relates to a kind of silicomanganese production method of using rotary kiln sintered powder and hot charging ore-smelting furnace, it belongs to a kind of production method of manganese alloy smelting.
Background technology
The method that iron alloy production at present adopts ore-smelting furnace directly to smelt ore is produced, the production stage of this method is: at first with the fine ore in the ore with after coke powder mixes, adopt sinter machine to sinter mineral into, agglomerating mineral cold conditions after fragmentation, screening adds ore-smelting furnace smelts, and taps a blast furnace to adopt mobile hot metal ladle separation slag, iron.Because aforesaid method uses sinter machine to sinter mineral into, its flue gas environmental pollution is serious; Particularly the flue gas of ore-smelting furnace could discharge because its temperature height needs to enter the sack cleaner dedusting after the air-cooler cooling, so air-cooler not only consumes heat energy but also form thermal pollution.For solving this difficult problem, many people attempt utilizing the flue gas of ore-smelting furnace to carry out cogeneration, but because the fluctuation of all the other heats is very big, make power generation system be difficult to steady running.Therefore, existing iron alloy production method exists that power consumption is high, contaminate environment serious and can't utilize shortcoming such as waste heat.
Summary of the invention
The objective of the invention is to solve existing iron alloy production method exist that power consumption is high, contaminate environment is serious and can't utilize the technological difficulties of waste heat and provide a kind of consume energy low, contaminate environment is little, output is high and the rotary kiln sintered powder of use that can recycle heat energy and the silicomanganese production method of hot charging ore-smelting furnace.
The present invention for the technical scheme that solves above-mentioned technological difficulties and adopt is: use the silicomanganese production method of rotary kiln sintered powder and hot charging ore-smelting furnace, it may further comprise the steps:
A. batching: at first silica, manganese ore, rhombspar, rich manganese slag are become granularity less than the powder of 50mm and be respectively charged into receiver bin with the ferric manganese ore raw material crushing, then prepare burden and mix by the proportioning raw materials of calculating;
B. sintering powder: the kiln tail of mixed powder being sent into rotary kiln through metering, the material that sinters granularity through rotary kiln sintered district into and be 5~70mm is from the rotary kiln end discharging, the temperature in rotary kiln sintered district is 850 ℃-1300 ℃, and the time of material in rotary kiln is 50-70 minute;
C. hot charging ore-smelting furnace: the material that will sinter granularity into and be 5~70mm is packed into by dolly and tremie pipe in the ore-smelting furnace, and the charging temperature of material is 680 ℃-900 ℃, adds coke powder 180~240kg again by ore deposit per ton simultaneously;
D. smelt: material was smelted in ore-smelting furnace 6 hours, became silicomanganese slag iron mixing liquid to come out of the stove;
E. slag iron separates: silicomanganese slag iron mixing liquid is flowed in the fixing calm hot metal ladle, carry out slag iron and separate;
F. cast: the silicomanganese molten iron that removes slag is cast in the mould;
G. recovery waste heat: the high-temperature flue gas of ore-smelting furnace collected and deliver to rotary kiln end and coal dust spray combustion back formation high-temperature gas jointly through pipeline, heating rotary kiln inwall and material, make the temperature in rotary kiln sintered district reach 850 ℃-1300 ℃, drop to 600 ℃ to rotary kiln behind this high-temperature gas sintered material, and then enter the settling pocket of kiln tail, separate crude particle dust, flue gas after the separation enters the waste heat boiler that is located between rotary kiln and the chimney through pipeline, this flue gas heats to waste heat boiler, making waste heat boiler produce temperature is 450 ℃, pressure is the steam of 38.5Mpa, this steam and circular fluid bed live steam pipe and vapour co-generation of power are constant with the energy output that guarantees power generation system.
Because the present invention adopts preheating in rotary kiln, sintered material, and, saved power consumption, accelerated change material speed, made ore-smelting furnace improve output 20%-50% with the electrically heated mineral aggregate with the ore-smelting furnace of directly packing into of the heat material behind the sintering.Adopt fixing calm hot metal ladle to tap a blast furnace, improved the rate of recovery of finished product.Adopt the generating of waste heat boiler recovery waste heat, can reduce the discharging of dust and flue gas, reduce the waste gas Greenhouse effect that discharging causes to sky, alleviate pollution atmosphere and environment.Adopt the generating of waste heat boiler and circular fluid bed paired running, can guarantee that the energy output of power generation system is constant, generating set runs well, and reaches the stable purpose of utilizing waste heat.Therefore, compare with background technology, have that power consumption is low, contaminate environment is little, output is high and can recycle advantage such as heat energy.
