Abstract
The artificial wallastonite is made up of lime stone and quartzite through smelting in cupola furnace and features low melting temp., regulatable chemical components and no crystal water, so not absorbing moisture.
Description
The present invention relates to a kind of prescription and technology of refining the artificial tabular spar of slag with cupola furnace, it belongs to the fusion product, can be widely used in smelting industry.
In the prior art, do not find the technology of producing artificial tabular spar, and natural wollastonite melt temperature in smelting process is higher, and about 1400 ℃, the calcium of natural wollastonite, silicon composition are comparatively fixing in addition, and the impurity instability, in the ore hand sorting process, it is comparatively difficult to select the wollastonite that is suitable for smelting industry, and natural wollastonite is owing to contain crystal water, the temperature height that in use needs wastes energy.
The purpose of this invention is to provide that a kind of raw material sources are abundant, melt temperature is low, can artificially adjust Chemical Composition, guarantee the component of silicon, calcium, aluminium, iron as required, the dawn does not have the prescription and the technology of the artificial tabular spar of crystal water.
The object of the present invention is achieved like this: the prescription of artificial tabular spar is: the ratio of Wingdale and two kinds of components of quartzite is (0.2-1.5): (1.0-3.0), wherein the content of calcium oxide is more than 40% in the Wingdale, and the content of silicon-dioxide is more than 50% in the quartzite.
The technology of artificial tabular spar is that Wingdale and the quartzite back material loading of preparing burden is in proportion entered cupola furnace, and the temperature of adjusting cupola furnace is between 1200-1700 ℃, and raw material is slagged tap after melting in cupola furnace.
Implementing the equipment of above-mentioned artificial tabular spar technology, is to use cupola furnace, and this cupola furnace has removed conventional furnace lining.
Also can include fluorite in the prescription of artificial tabular spar, Wingdale: quartzite: fluorite=(0.2-1.5): (1.0-3.0): (0.15-0.4), wherein in the fluorite content of fluorine more than 70%, the content of calcium oxide is more than 40% in the Wingdale, and the content of silicon-dioxide is more than 50% in the quartzite.
Compare with prior art; the artificial tabular spar raw material sources are abundant; in addition because this fusion product of artificial tabular spar does not contain crystal water; so melt temperature is low; nonhygroscopic; make this product the time as smelting covering slag base-material; can make the pre-molten covering slag by other composition of disposable adding; and natural wollastonite needs fusion as covering slag the time; after the technologies such as compensation burning; add other composition again; make covering slag; above-mentioned advantage also makes artificial tabular spar as the welding rod auxiliary material time; improve the usability of electrode energy effectively, improve the viscosity of slag, make slag that good wetting property and good slag detachability be arranged; make the sloping moulding densification of weldering attractive in appearance, and the stainless steel electrode made from artificial tabular spar is anti-rubescent; do not ftracture.The melt temperature of artificial tabular spar is low, generally about 1100 ℃, so can save the energy.The Chemical Composition of artificial tabular spar can be adjusted as required, guarantees the component of silicon, calcium, iron, aluminium, is suitable for the application on the different condition different field.
