Sintering refining slag

The premelting type refining slag (calcium aluminates, desulfurization agent) is a kind of compound deoxidization, desulfurization materials, is a steel enterprise steelmaking refining process will use additives. Fused calcium aluminates chemical components uniform, low melting point, melting speed, can shorten the smelting of time; Not containing fluorine, not erosion lining and ladle; The compact structure, easy for storage and transportation, absorbing the storehouse; Because object is stable, into slag fast, can reduce dust pollution of steel, overall stability refining process; Do not contain hydrogen, nitrogen, carbon impurity, to improve steel quality. In many similar products, and on the basis of my company combining domestic and foreign research and production technology, make the product revision in the past in refining process rely on high alkali materials, slag just mix out, the desulfurization of outside the furnace traditional process, so as to improve the quality of steel products internal use and performance.

The properties of product:

1, with effective deoxidization, desulfurization function, and can make the sulfide molten steel, the oxide reduced to the minimum degree, desulfurization, deoxidization ability strong, do not produce the sulfur back phenomenon, make steel products stable structure, so as to improve the quality of steel products.

 2, has the trinity function: desulfurization, deoxidization, submerged arc.

 3, have extremely strong heat preservation function, submerged arc can shorten the time after refining, improve efficacy.

 4, direct dosing use, no residual impurities, reduce labor intensity, improve efficiency.

 5, reduce the power consumption of the refining.

 6, non-absorbent, facilitate storage and transportation.

 7, reduce the increase smelting hydrogen.

 8 and slag washing effect now lives, adsorption inclusion obviously.

 9, not containing fluorine, and protect the ecological, not erosion lining, reduce the consumption of ladle refractory materials.

 Technical features:

 The premelting type refining slag, is in the refining technology with certain change before slag device will slagging material to get ahead of the product of molten combined. It is no longer the mixture of machinery, but the slag in the device in the complicated physical and chemical reaction by the formation of the complex compounds, and components uniform stability, no water, no into slag hydration, quickly, and is now widely used traditional solid synthesis slag has essential difference.

1, melt temperature was significantly lower than the mechanical slag mixed, and has a low melting point, high melting speed, sparkling performance good characteristic.

2, only the few energy can form quickly liquid slag, have good spread sex, covering the surface of steel, steel liquid and air insulation, reduce the molten steel absorb H2-O2-N2.

3, it allows GeChang according to the site conditions with lime accurately adjust the slag, in order to form the highly alkaline liquid lime saturated slag.

4, desulfurization effect is better than that of machinery in the residue of refining slag mixed, the desulfurization rate than mechanical mixing slag, at the same time, the lower sulfur in steel slag mechanical mixing, achieve the purpose of deep desulfurization.

5, avoid using fluorite (it on the environment and refractories are harmful)

6, surface tension, it absorbed the inclusion of steel, and can improve performance at high magnification (micro).

7, shorten the cycle of smelting slag and material consumption, meet energy efficient production effect.

8, because do not absorption of moisture, reduce the pollution of H2 steel danger.

Steel enterprise production because of the clean steel demand, our company developed a low ti low sulfur low silicon refining slag, this refining by X-ray diffraction content slag phase analysis results show the basic content in 12 CaO-7 Al2O3 type calcium aluminates, melting point in 1400 ℃ below, its content phase composition belong to the level of the slag, besides having the characteristics of variety single outside, and low content of impurities, especially SiO2, TiO2 Fe2O3, the content is low, it is in bauxite calcining aluminum acid calcium refining slag can achieve that.

Physical and chemical index:

Method of use:

 Join quantity can according to the decision process conditions, suggest 5-12 kg/tons advisable, also can be divided into two times to join, the steel is to join and finer add. The ladle bottom blowing argon mix, make steel gas drink impurity content fully rise, and make the liquid steel temperature and chemical components uniform, improve the grade of molten steel, obviously improve the quality of the just.

Packaging: plastic composite materials tons bag (1000 kg), (500 kg), also according to the client's demand.
