SiAlBaCa Inoculant

At present, silica-Barium alloy as a pure deoxidizing agent less steel, more with strontium, aluminum, calcium, elements compound and become a multi-alloy, so in addition to silica-calcium alloy, other silica-calcium, silica-aluminum-barium, silica-Aluminum-Barium, silica-Aluminum-Barium and other alloys are using silica-barium as alloy additives, so the market surface is wider than the other multi-alloy, large dosage.

In steelmaking, silica-Barium has strong deoxidation capacity and desulfurization function. In casting, silica-Barium is a better inoculant. Silica-barium alloy is mainly used in the production of excellent special steel. It is an indispensable deoxidizer for pure steel metallurgy.

USES of silica-Aluminum-Barium calcium:

Silica-aluminum-ba-ca is a good deoxidizer and desulfurizer in ba-series alloy, which can greatly reduce the oxygen content in steel. The complex inclusions containing calcium, barium and aluminum formed at the same time are easy to float up from the pot liquid. Pure liquid steel. Improve the impact toughness and machining properties of steel. Compared with pure aluminum, ferrosilicon, silica-calcium alloy, the effect is better and the utilization ratio of the alloy is higher. Silica-aluminum-barium calcium is less soluble in molten steel, can dissolve calcium and reduce calcium vapor pressure, in silica-aluminum-Barium calcium alloy can fully improve the role of calcium in deoxidation and non-metallic inclusion treatment;

Application:

High efficiency deoxidizer of silicon, calcium, barium and aluminum is the material for steelmaking shaft. It is suitable for deoxidization of many steelmaking forms, especially for converter steelmaking. It has a strong effect of deoxidation and desulfurization, which can improve the flowing property of molten steel, solve the problem of water nodule, reduce gas in steel, and reduce liquid steel inclusion. Silicon calcium barium aluminium is the ideal deoxidizer and desulfurizer in steelmaking. Calcium has great affinity for oxygen and sulfur, silicon also has great affinity for oxygen, barium not only has great affinity for oxygen and sulfur, and barium can effectively reduce the vapor pressure of calcium and improve the utilization rate of calcium in the range of steelmaking temperature. The experiment of steelmaking deoxidization shows that using silica-calcium barium deoxidization is more effective than using silica-calcium compound deoxidizer. The complex oxides containing calcium, barium and silicon are easy to float up from the molten steel, making the molten steel pure and widely used in the deoxidation of steel, especially the deoxidation of continuous casting steel with this deoxidizer, which not only improves the fluidity of steel, improves the quality of steel, but also reduces the cost of steel. In the production of cast iron, the deoxidizer is not only an effective inoculant, but also plays a good deoxidizing and desulfurizing effect.

Use results show that the silicon aluminum barium calcium alloy DNA can make the total oxygen content of the billet between 9 and 15 PPM: can make the inclusions in the steel (compared with other deoxidizer) by around 75-809%, can make the inclusions in the area of distribution is on the decline, the reason is that the silicon aluminum barium calcium DNA, its inclusion aggregation and buoyancy grow up faster than aluminium deoxidizing inclusion quantity can quickly achieve the low level: to change shape of debris, spheroidizing effect is more noticeable inclusions: can refine ferrite grain and enhance impact resistance toughness and processing properties of steel, improving steel liquid, prevent the nozzle blocking. The use of silica-Aluminum-Barium calcium for deoxidation of molten steel can reduce the steelmaking process (can replace the use of a variety of deoxidizer), improve product quality, reduce production costs.

Si-Al-Ba-Ca is the most effective deoxidizer and desulfurizer in the Barium alloy.

♦ It can extremely reduce the oxygen in the steel and make the complicated oxide contains Ca/Ba/Si/Al easier to flow from the molten steel, so as to pure the steel and improve its toughness.

♦ Excellent deoxidizer of Steel making secondary material, widely used in varies steel types especially well applied in BOF steelmaking deoxidization, improve the liquidity of molten steel and avoid built-up at the nozzle. Decrease gas and impurities
