Description
Technical field
The invention belongs to the technical field of inorganic materials technique.Specifically, the present invention relates to the volume control device produced for induction furnace operating mine slag wool, rock wool, devitrified glass, cast stone.
Background technology
At present, in domestic mineral wool, rock wool production process, most of producer uses furnace cupola as melting unit, and basalt, slag, dolomite etc. are made fiber with supply fiberising apparatus after coke fusing in furnace cupola.The raw materials such as fusing ore can cause a large amount of energy resource consumptions and more serious environmental pollution.
Furnace cupola leans on and controls composition into furnace charge amount, and reaction time is long; The control of melt temperature and quantity delivered, regulates by coke proportioning and air port, and temperature and quantity delivered exist to be contacted directly, and improves quantity delivered and all cannot realize, control inconvenience when reducing quantity delivered or cooling during intensification.Fiber forming apparatus produce the short time when interrupting in stove melt must flow to accident hole by chute, can not blowing out, otherwise after cool stove again former, the fuel of blow-on and time waste very big.Use furnace cupola to prepare melt, big for environment pollution, energy consumption is high, belongs to country and eliminates technique.
Some enterprises obtain hot slag from blast furnace, heat up, and supply fiberising apparatus after carrying out small size composition adjustment, produce mineral wool with electric arc furnaces (arc resistance furnace) to hot slag.Arc resistance furnace directly can utilize hot slag, uses high-precision hydraulic pressure, electric system to control smelting furnace constant speed and tumbles to control melt flow.But this type of equipment thermal efficiency is on the low side, and big current, short net impedance to cause electricity to damage large, electrical efficiency, power factor are lower, and energy loss is large.Simultaneously due to high-temperature electric arc scaling loss electrode, cause that consumption of electrode is large, residue contaminated melt.And electric arc can impel between the materials such as C, SiO2, CaO, MgO and reacts, generate the material such as silicate, carbide, part is mixed into slag liquid, part in furnace bottom deposition, contaminated melt, composition and poor temperature uniformity; Affect slag liquid quality and the working of a furnace.Plant maintenance amount is large, starts the material that must add conduction, slag liquid quality is changed when black furnace or melt crust.Larger to the impact of electrical network when the starting the arc, current interruption.
Due to above defect, the technique of arc resistance furnace heat hot slag fails to apply at home.
There is the method for the combustion gas tank furnace heat hot slag of the similar glass furnace of some enterprises, produce the mineral wool of Low acid coefficient, control melt flow with sideboard.But the method is limited to the intensification of tank furnace and modified ability, can only the poorest mineral wool of production quality, be not suitable for the mineral wool of acidity coefficient more than 1.2, rock wool produces.The necessary continuous setup of composition in combustion gas tank furnace stove, during the product that production different components requires, regulation time is long, efficiency is low, and waste is large, and melt intensification is difficult to more than 1500 DEG C, and in stove, melt cannot stir, and composition uniformity is poor.
Devitrified glass, cast stone generally use cupola melting ore, then melt transfer is incubated in combustion gas tank furnace in producing, and add Nucleating Agent and make its uniform ingredients by melt natural flow, then carrying out cast molding.This technique melt flow controls with combustion gas tank furnace operating mine slag wool similar.The necessary continuous setup of composition in stove, during the product that production different components requires, regulation time is long, efficiency is low, and waste is large.And melt intensification is difficult to more than 1500 DEG C, in stove, melt cannot stir, and composition uniformity is poor.The raw materials such as fusing ore can cause a large amount of energy resource consumptions and more serious environmental pollution equally.
