Abstract
The present invention relates to metallurgy sintering technology, particularly to a device for wrapping liquid state fuel agents by mixing materials of a sintering machine and liquid state fuel agents for the device. The device comprises a slurry storage tank for storing the liquid state fuel agents, wherein the slurry storage tank is connected with an atomizer arranged above a mixer batch layer by a slurry transmission pipeline, and a slurry transmission pump is arranged on the slurry transmission pipeline. The liquid state fuel agents is suspended liquid fluid, and are composed of raw material components of the following proportion by weight: 65 to 70% of solid washed head coal and 30 to 35% of water, and combustion improver, assistant thawing agents and adhesives which account for 0.5 to 1% of weight percentage of the solid washed head coal and stabilizing agents which accounts for 0.3 to 1% of weight percentage of the solid washed head coal are added in the liquid state fuel agents. Compared with the method for directly wrapping solid coal powder by mixing materials, the device and the liquid state fuel agents have the advantages of less equipment investment, simple operation technology and enough intensity and favorable reducibility for sintering ore, and the drum strength of finished sintering ore can be reduced to 3 to 5%. Owing to sintering temperature and fuel dossage is easy to control, burnup can be reduced by 10 to 30%, sintering ignition temperature can be reduced by 50 to 100 DEG C.
Description
Technical field:
The present invention relates to metallurgy sintered technology, particularly a kind of equipment for wrapping fuel agent in liquid state on mixing material for sinter machine fuel agent in liquid state.
Background technique:
The conventional sintering method is the sinter mixture that the iron-bearing minerals such as fuel (coke powder or anthracite), flux and mixing ore deposit that add some are formed, and after adding water mixing and granulation, cloth is lighted a fire then and carried out the burning of exhausting formula to sintering pallet.This fuel is directly mixed SINTERING PRODUCTION in the raw materials for sintering, need a large amount of fuel, the production of general sintering deposit per ton consumes about 55 kilograms of fuel, and the sintering ignition temperature is higher simultaneously.For addressing the above problem, adopt at present raw material is caused bead, wrap up in outward and also join part coal (Jiao) powder in coal (Jiao) powder or the bead, on the ordinary sinter machine, carry out the method for sintering then.Adopt this sintering method, need original SINTERING PRODUCTION technology is transformed completely, implementation procedure will increase technological processes such as defeated material, fragmentation, storage bin, bedding plant, invest bigger, even still be all to be to be difficult to bear from the occupied ground angle to newly founding the factory from investment.
Summary of the invention:
Purpose of the present invention is intended to solve the described deficiency of background technique, and a kind of equipment for wrapping fuel agent in liquid state on mixing material for sinter machine fuel agent in liquid state is provided, and to improve the quality of sintering deposit, reduces sintering energy consumption simultaneously, saves equipment investment.
The technological scheme that realizes the object of the invention is as follows:
A kind of equipment for wrapping fuel agent in liquid state on mixing material for sinter machine fuel agent in liquid state, described device comprises the slurry can of a storing liquid combustion agent, this slurry can is connected with the atomization spray cap that is arranged on mixing machine bed of material top by grout pipe line, on this grout pipe line liquid feeding pump is housed; Described device is the suspension fluid with its figure of fuel agent in liquid state, its material component and weight percentage thereof are solid clean fine coal 65～70%, water 30～35%, add in addition that to account for solid clean fine coal weight percentage respectively be 0.5～1% combustion improver, flux, binder and 0.3～1% stabilizer.
According to this equipment for wrapping fuel agent in liquid state on mixing material for sinter machine and the used fuel agent in liquid state of this device that this case provides, exhausting formula sintering process adopts in the suitable especially present Ferrous Metallurgy production, compares with background technique, has the following advantages:
1, little investment.
Use this device, only need set up slurry can, liquid feeding pump, atomization spray cap and grout pipe line, gross investment will be controlled at below 400,000 yuan.
2, technology is simple.
Use this device and special liquid thereof combustion agent, its technology controlling and process and former technological process do not clash, and the operator can operate by former technological process and get final product.
3, effect doubles.
Mixture is wrapped up in fuel agent in liquid state outward and wrap up in solid-state coal dust outside directly, the outer surface that is blended in raw material ball that more can be full and uniform, the low-temperature reinforcement composition that additive had in the fuel agent in liquid state is rolled in the outer surface that mixes pellet simultaneously uniformly, making the small structure of sintering deposit is the sintered balls structure, becoming the ore deposit is a plurality of pellet sinterings uniform botryoidalis together, make sintering deposit have enough intensity and good reducibility, the drum strength of finished product sintering deposit will reduce by 3～5%.Because sintering temperature and firing rate are controlled easily, so burnup can reduce by 10～30%, and the firing temperature of sintering will reduce by 50～100 ℃ simultaneously.
