Parameter is：Electric current declines 10000 ~ 15000A on the basis of rated current, and voltage improves 10 on the basis of rated voltage ~
20V, makes the Current Voltage of mineral hot furnace than dropping to 380 by specified 440.
The method that focal sphere is produced, step are added in described mineral hot furnace（5）Described in come out of the stove the time and mode is
Go out a stove within 80 minutes, it is ensured that the duration of heat of each stove is more than 40 minutes, while each stove eye must assure that when continuously coming out of the stove
Between more than 10 days, liquid in stove is formed fixed flow channel, be easy in stove that impurity is as product is excluded in time, so as to protect
Card furnace bottom does not have impurity deposition, extends mineral hot furnace usage cycles.
Beneficial effect：
Compared with prior art, the invention has the advantages that：
1. the present invention is not required to increase any burden of enterprise or input；
2. solid waste of the present invention is utilized, it is ensured that manufacturing enterprise's environment is not secondary polluted；
3. the present invention can reduce by 200 ~ 700 yuan/ton of the production cost of manufacturer.
Embodiment
With reference to embodiment, the present invention is furture elucidated, it should be understood that following embodiments are only used for
The bright present invention rather than limitation the scope of the present invention.
Embodiment 1：
The method that focal sphere is produced is added in mineral hot furnace, this method comprises the following steps：
（1）Ensure that focal sphere and main raw material of wood-charcoal mix ratio by belt conveyer scale stable；According to daily focal sphere output and mineral hot furnace charcoal
The usage amount of material, determines that focal sphere mixes ratio between 30 ~ 50%, while to ensure master during feeding by the metering of charging belt scale
Raw material of wood-charcoal（Coke, semi-coke）It is synchronous with focal sphere, i.e.,：It is main raw material of wood-charcoal below belt, is focal sphere above.Again by transhipment building and proportioning station
Multiple mixing, to ensure uniformity of the focal sphere in furnace charge.Focal sphere described in the present embodiment uses coke powder and accounts for coke powder
Adhesive of the weight than 3%-3.5% is thoroughly mixed, and is then a granulated into 30-50mm, and finally drying is formed, and described is viscous
Mixture by weight include 30-50 parts of cornstarch, 3-5 parts of yellow starch gum, 8-13 parts of pre-gelatinized starch, 15-25 parts of piece alkali,
15-25 parts of PVC, 1-3 parts of cement, 2-6 parts of coal tar.
（2）Adjust charge composition scope；Make the adjustment within 0.5 ~ 1% on the basis of former charge composition；Because focal sphere adds
2 ~ 3% extraordinary binders are added, its main component is organic matter, it is therefore desirable to according to product quality（Calcium carbide, steel, ferrosilicon）'s
Variation tendency, in former charge composition（58~61%）On the basis of make 0.5 ~ 1% within adjustment.
（3）Because mineral hot furnace can produce substantial amounts of high-temperature gas and melt liquid during electric energy is converted into heat energy,
Charge level temperature can also enter stove chamber inner combustion because of air in addition to the sensible heat in stove and raise and cause charge level hardened and serious shadow
The gas permeability of the bed of material is rung, therefore strictly to control furnace pressure in process of production in 5 ~ 20P of malleation, in case air enters in burner hearth,
Furnace surface temperature is controlled between 600 ~ 700 degree.To pay close attention to the blanking situation of 15 expects pipes often in addition, such as find which phase electrode has
The not smooth phenomenon of blanking, it is necessary to which adjustment electrode position and stokehold plug for outlet are come out of the stove in time, it is ensured that all expects pipe blankings are balanced.
（4）Ensure the stability of load by adjusting the operation electric parameter of mineral hot furnace；The operation electric current of mineral hot furnace, electricity
The electric parameters such as pressure, resistance directly influence the links such as produce load, product quality, material consumption energy consumption, when mixing focal sphere production
To consider comprehensively the particle diameter of focal sphere, activity, calorific intensity, integration and with the factor, operation electricity such as the surface area contact ratio of lime
Stream declines 10000 ~ 15000A on the basis of rated current, and voltage improves 10 ~ 20V on the basis of rated voltage, makes ore deposit heat
The Current Voltage of stove by specified 440 than dropping to 380.To ensure that charge level in stove reaches the effect of bulk settling by expanding molten bath
Really.
（5）Ensure that product quality is unaffected by changing time of coming out of the stove and mode.
In mineral hot furnace production process, it is to be ensured that product quality is unaffected, its duration of heat is to ensure.Therefore to change with
It is to go out a stove in 80 minutes toward a stove is gone out within 60 minutes, it is ensured that the duration of heat of each stove is more than 40 minutes.While three stoves of coming out of the stove
Eye accomplishes out that two is standby as far as possible, i.e., each stove eye, which must assure that, continuously comes out of the stove the time more than 10 days, liquid in stove is formed solid
Fixed flow channel, is easy to impurity in stove as product is excluded in time, so as to ensure that furnace bottom does not have impurity deposition, to extend mineral hot furnace
Usage cycles.
