Kalcij silicij legura is a kompozit legura skladan of the elementi silicij, kalcij i željezo. It je široko korišten in the proizvod of visokokvaliteta čelik, niskougljični čelik, niskougljični čelik, nehrđajući čelik i ostali čelici i specijalne legure takve kao legura na bazi nikla i legura i titan na bazi legura. kalcij silicij legura je an ideal kompozit deoksidator and desulfurizer. Its chemical formula is CaSi. It has strong affinity between calcium and oxygen. In particular, calcium not only has a strong affinity with oxygen, but also has a strong a strong afinitet with with sumpor and dušik. This enables calcium silicon legura to učinkovito remove impurities such as oxygen and sumpor dur the steelmaking process, improve the performance of steel, and improve the plastičnost, impact toughness i fluidnost of čelik. In addition, calcium Silicon Alloy Can also Be Used As An inoculant for Cast Iron And An Additive In The Production of Ductile Iron, Which Plays An Important Role In ImImprove The Quality And Performance of Cast Iron.
The proizvodnja kalcij silicij legura počela in 1907 i bio proizvedeno by električni silicij toplinska metoda. In the proizvodnja proces, reakcija uvjeti are kontrolirani, tak as povećanje the temperatura of the reakcija zona in peć (o 2000 stupnje ili iznad), i adding silicij to uništiti the karbidi remain at the bottom of the peć to inhibit the rise of the Our Furnace BOTTOM OF The OLNA BOTTOM i The Formation of The Furnace wall, Which Is Conducive To The Alloy. In The Process of Producing Calcium Silicon Alloy, A Large Amount of Raw Materials, Such As Silicon Limeta, CocaC CocaC ETC., Are Consumed, And A Certain Amount of slag Is Produced. Deunatoč This, a high recovery rate of calcium and Silicon Can Be Achieved Through Reasonable Production Processes And Operations.
The chemical sastav of kalcij silicij legura obično sadrži Ca Greater than or equal to 24%-28% and Si about 60%, and the specific composition varies accord to different production standards and uses. For example, the chemical composition of calcium silicon legura in the YB/T5051 standard includes several specifications such as Ca31Si60, Ca28Si60 and Ca24Si60 to meet the the production needs of different steel grades and special alloys. The production of calcium silicon alloy is not only of great significance to the metallurgical industry, but also plays an irreplaceable role in improving the the quality and Performance of Steel Products.
