Calcium silicon alloy is an ideal deoxidizer and desulfurizer currently used in the production process of high-quality steel, special steel and special alloys. It is also used as an inoculant for cast iron and an additive in the production of ductile iron. Both calcium and silicon have strong affinity with oxygen. Calcium, in particular, has a strong affinity not only with oxygen, but also with sulfur and nitrogen. Calcium silicon alloy not only has strong deoxidizing ability, and the deoxidation products are easy to float and be discharged, but also can improve the properties of steel and improve the toughness, impact toughness and fluidity of steel.   The role of calcium silicate blocks in steel smelting is mainly reflected in the following aspects:  1.Desulfurization: The silicon and calcium in the calcium silicate block have strong reducing properties and can react with the oxides in the molten steel to generate volatile gas hydrogen sulfide (H2S), thereby reducing and volatilizing the sulfur in the molten steel. Go out to achieve the purpose of desulfurization and improve the quality of steel.  2.Deoxidation: The calcium in the calcium silicate block reacts with the oxides in the molten steel to form calcium oxide, and participates in the formation of the oxide envelope of the steel, thereby reducing the oxygen content in the molten steel, thereby improving the purity and purity of the steel. strength.  3. Alloy adjustment effect: Silicon and calcium in calcium silicate blocks are both reducing agents and alloy elements. Adding calcium silicate blocks to molten steel can adjust the non-metal content in the molten steel and cause changes in the alloying elements in the steel. For example, calcium silicate blocks with higher silicon content can be used to increase the silicon content and increase the content of the alloying element silicon, thereby improving the properties of steel and adapting to different application requirements. Calcium silicon electric furnace production process: The production of calcium silicon alloy is relatively complex. The main raw materials in the production process are quartz (Si02,), limestone (CaCO3,) and reducing agent mixture (mainly coke and bituminous coal).  Calcium silicon alloy is produced by reducing silicon dioxide and calcium oxide using a carbonaceous reducing agent in a reduction electric furnace. The conventional production methods of calcium silicon alloy can be divided into three types, namely: mixed feeding method, layered feeding method and two-step method. Mixed feeding method, also known as one-step method. Use a carbonaceous reducing agent to simultaneously reduce silica and calcium oxide, that is, mix all the raw materials evenly and add them into the furnace in small batches. The mixing and feeding method is simple to operate and easy to control.

 

철강 제련에서 규산칼슘 블록의 역할은 주로 다음 측면에 반영됩니다.

 

1. 탈황: 규산칼슘 블록의 규소와 칼슘은 환원성이 강하고 용강의 산화물과 반응하여 휘발성 가스인 황화수소(H2S)를 생성하여 용강의 황을 환원 및 휘발시킬 수 있습니다. 탈황의 목적을 달성하고 철강의 품질을 향상시키기 위해 나가십시오.

 

2. 탈산 : 규산칼슘 블록의 칼슘이 용강 중의 산화물과 반응하여 산화칼슘을 형성하고, 강의 산화물 외피 형성에 참여하여 용강 중의 산소 함량을 감소시켜 용강의 성능을 향상시킨다. 강철의 순도와 순도. 힘.

 

3. 합금 조정 효과: 규산칼슘 블록의 실리콘과 칼슘은 모두 환원제이자 합금 원소입니다. 용강에 규산칼슘 블록을 첨가하면 용강의 비금속 함량을 조정하고 강철의 합금 원소를 변화시킬 수 있습니다. 예를 들어, 규소 함량이 높은 규산칼슘 블록을 사용하면 규소 함량을 높이고 합금 원소 규소의 함량을 높일 수 있으므로 강철의 특성을 개선하고 다양한 응용 요구 사항에 적응할 수 있습니다. 칼슘 실리콘 전기로 생산 공정: 칼슘 실리콘 합금의 생산은 상대적으로 복잡합니다. 생산 공정의 주요 원료는 석영(SiO2,), 석회석(CaCO3,) 및 환원제 혼합물(주로 코크스 및 역청탄)입니다.
