Abstract
The invented protecting slag base material is made up by using limestone, quartz stone and lithium salt as raw material through the processes of mixing, stirring uniformly, feeding them into cupola, regulating temp. of cupola to 1200-1700 deg.C, melting raw material in the cupola and discharging slag.
Description
The present invention relates to soaring prescription and the manufacturing process thereof of being jealous of the protective-dregs base-material of artificial wollastonite of refining slag of a kind of usefulness, it belongs to the fusion product, can be used for 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; about 1400 ℃; calcium in the natural in addition wollastonite; the silicon composition is comparatively fixing; and impurity instability; in the ore hand sorting process; select the wollastonite difficulty comparatively that is suitable for smelting industry, and natural wollastonite is owing to contain crystal water, the temperature that in use needs is higher; waste energy; applicant oneself has developed a kind of protective-dregs base-material of artificial wollastonite and has been applicable to general smelting steel, is not suitable for the especially stainless smelting of special steel, and the covering slag in existing special steel such as the stainless smelting process all is that physical method mixes; need whipping device; also mix inequality, the easy moisture absorption, thus cause caking.
The purpose of this invention is to provide a kind of melt temperature low, can artificially adjust chemical ingredients, guarantee silicon, calcium, lithium component as required, and do not have a crystal water be applicable to the special steel especially protective-dregs base-material of artificial wollastonite and the manufacture craft thereof of stainless steel smelting.
The object of the present invention is achieved like this: protective-dregs base-material of artificial wollastonite; it is as follows that its prescription is formed weight ratio: lithium salts: (Wingdale+quartzite)=(0.93-14.8) %: 1; and Wingdale wherein: quartzite=1: (0.2-1); calcium oxide content is more than 40% in the above-mentioned Wingdale; the content of silicon-dioxide is more than 50% in the quartzite, and lithium salt content is more than 98%.
The manufacturing process of above-mentioned protective-dregs base-material of artificial wollastonite is passed through following step successively:
1. the back material loading of Wingdale and quartzite being prepared burden according to the above ratio enters cupola furnace,
2. lithium salts is also sent in the cupola furnace by the weight of above-mentioned and Wingdale and quartzite and proportioning and is stirred,
3. the temperature of adjusting cupola furnace is between 1200-1700 ℃, and raw material is slagged tap after melting in cupola furnace.
Compare with prior art; former dose of source of artificial tabular spar is abundant; in addition because this fusion product of artificial tabular spar does not contain crystal water; so melt temperature is low; nonhygroscopic; save the energy; can artificially adjust Chemical Composition in addition; guarantee silicon as required; calcium; the lithium component; covering slag base-material of the present invention can add other composition and make the covering slag of pre-molten covering slag as special steel especially stainless steel smelting; melting type product of the present invention is compared with the covering slag of present mixed type, and qualitative leap has been arranged, and its quality is even; need not whipping device, manufacture craft is simple.
Be described in detail technical solution of the present invention below.
Embodiment 1:
Protective-dregs base-material of artificial wollastonite, it is as follows that its prescription is formed weight ratio:
Lithium salts: (Wingdale+quartzite)=0.93%: 1, and wherein the weight ratio of Wingdale and quartzite is 1: 0.2,
Lithium salts is a Quilonum Retard.
The manufacturing process of above-mentioned protective-dregs base-material of artificial wollastonite is passed through following step successively:
1. the back material loading of Wingdale and quartzite being prepared burden according to the above ratio enters cupola furnace,
2. lithium salts is also sent in the cupola furnace by the weight of above-mentioned and Wingdale and quartzite and proportioning and is stirred,
3. the temperature of adjusting cupola furnace is between 1200-1700 ℃, and raw material is slagged tap after melting in cupola furnace.
Embodiment 2:
Protective-dregs base-material of artificial wollastonite, it is as follows that its prescription is formed weight ratio:
Lithium salts: (Wingdale+quartzite)=5%: 1, and wherein the weight ratio of Wingdale and quartzite is 1: 1,
Lithium salts is a Quilonum Retard.
This routine manufacturing process is with embodiment 1.
Embodiment 3:
Protective-dregs base-material of artificial wollastonite, it is as follows that its prescription is formed weight ratio:
Lithium salts: (Wingdale+quartzite)=14.8%: 1, and wherein the weight ratio of Wingdale and quartzite is 1: 0.6,
Lithium salts is a Quilonum Retard.
This routine manufacturing process is with embodiment 1.
Lithium salts also can be tetrahydrochysene and closes lithium aluminate Li[AlH among above-mentioned three embodiment
4].
