Description
Technical field:
The present invention relates to a kind of bonding balling-up method of coke powder, specifically, the present invention relates to a kind of method with the coke powder bonding coking powdered carbon ball of generation in the metallurgical industry production, this coke sphere of powder is used for manganese system and chromium is the iron alloy production field, not only greatly reduce production cost, but also reduced the environmental pollution that causes because of the coke powder.
Background technology:
In many metallurgical industry industries, in productions such as iron alloy, yellow phosphorus, industrial silicon and Iron And Steel Industry, all need to use in a large number coke, according to the requirement on the Technology, all need coke is crushed to the use granularity that needs separately, when the coke crushing operation, can produce the coke powder of about 10-20% inevitably, and just be difficult to utilize again when usually the granularity of coke powder is less than 5 millimeters, when granularity almost just not have the value of directly utilization during less than 3 millimeters.Because the surface-area of coke powder is big, and density is little, need more stacking place in addition,, cause pollution air and environment in case sun drying will fly upward with the wind.
At present, the coke powder that produces during metallurgical industry is produced mainly is utilized by following two kinds of approach: 1) replace coal dust as the collocation material of producing agglomerate; 2) with behind water glass or the group's balls such as coal tar and pitch use.The former is restricted usage quantity, and uneconomical; Latter process's long flow path needs specific equipment such as rotary kiln to carry out hot consolidation and can use the cost height after with the physical strength that increases pelletizing.
Summary of the invention:
The present invention is intended to overcome above-mentioned defective, and a kind of method with coke powder bonding coking powdered carbon ball is provided.This method technical process is short, cost is low, efficient is high, can solve the problem that metallurgical industry coke powder can not be used effectively, and can curb environmental pollution again, and can also reduce the comprehensive cost that iron alloy is produced.
The present invention realizes the object of the invention by the following technical solutions.
A kind of bonding balling-up method of coke powder is characterized in that comprising following processing step:
A, batching and metering: the proportional meter content of starting materials of allocating binding agent 5-30 weight part and water 5-20 weight part by coke powder 100 weight parts into;
B, stir: the raw material after the steps A metering is poured into carried out stirring and evenly mixing in the stirrer and get compound;
C, compacting balling-up: the compound that step B is made adds in the ball press and is pressed into pelletizing;
D, fixed naturally: the pelletizing of step C compacting is stacked more than 4 days naturally, promptly got the product coke sphere of powder of the present invention after fixed.
It is 65-88% that described coke powder contains fixed carbon, and granularity is less than 5mm.
Described binding agent is a cement, or the mixture of one or any both or three in cement and wilkinite, yellow mud, the gypsum.
The specification of the product coke sphere of powder of the present invention is: granularity 10-50mm, chemical ingredients is: fixed carbon 55-82%, ash 15-40%, than resistance 8 ∽ 45 Ω .mm
2/ m.
The invention has the advantages that:
1, the present invention adopts the method with addition of binding agent form coke powdered carbon ball, though suitably reduced the fixed carbon content of the coke sphere of powder, increased ash, but use the coke sphere of powder for the production of slagprocess iron alloy, designed more rational ash chemical ingredients and than resistance value index, what help producing carries out smoothly, has reduced comprehensive production cost.
2, the present invention uses the metallurgical coke powder production iron alloy coke sphere of powder under the cheap sieve, can substitute the expensive qualified metallurgical coke of part fully, has reduced the iron alloy production cost of products.
3, the present invention has not only solved the problem that metallurgical industry coke powder can not be used effectively, but also has administered the pollution of coke powder to environment effectively.
4, the present invention has realized the comprehensive utilization of metallurgical industry coke powder resource.
5, technical process of the present invention is short, cost is low, efficient is high.

The analysis of coke sphere of powder performance:
In the manganese-silicon products production, the adjustment of slag slag type is extremely important, dual alkalinity in the slag and Al
2O
3Content is to reducing Mn content and raising SiO in the slag
2Utilization ratio play very crucial effect.
Dual alkalinity can play MnO activity in the raising slag by emphasis in the slag in suitable scope, strengthens the ability that is reduced of MnO, and reduces the effect of Mn content in the slag, improves SiO simultaneously
2Utilization ratio.Al in the slag
2O
3Content can play the raising slag temperature by emphasis in suitable scope, improve the furnace reduction speed of response, improves SiO
2The effect of utilization ratio, simultaneously, improve the dynamic conditions that MnO is reduced.
As the natural alkalinity (R in the raw material
Binary) and Al
2O
3Content is low, directly influences the adjustment of manganese-silicon metallurgical slag type, and the consequence of generation shows as MnO content height (10-15%), SiO in the slag
2Si is low in utilization ratio low (35-48%), the product.Dual alkalinity and Al in the coke sphere of powder ash
2O
3After content is improved, can reduces the auxiliary material (as rhombspar etc.) that residue adjustment is used in right amount, and reach identical slag type, help carrying out smoothly of manganese silicon smelting process.
Ratio resistance (12 ∽, the 45 Ω .mm that the coke sphere of powder is higher
2/ m), the dark of electrode inserted when helping smelting, and therefore helps the electric furnace oepration at full load, improves furnace temperature, improves the utilization ratio of manganese and silicon.
The carbon reduction capability analysis:
The coke sphere of powder is compared with metallurgical coke, and fixed carbon content is low, scaling loss is big, and under the equal in quality, coke sphere of powder reducing power is not as metallurgical coke.For improving this situation, we consider from granularity, increase the granularity of the coke sphere of powder, reduce its specific surface area, effectively reduce the scaling loss of the coke sphere of powder, have reached to make full use of carbon content in the coke sphere of powder, improve the comprehensive reducing power of the coke sphere of powder.
