转炉大面修补新工艺,mgo-cao修补料

 

1400度左右混合料有液相出现,1500度液相量激增,混合料中,主要矿物包含:硅酸二钙,方钙石,方镁石,氧化亚铁,镁橄榄石,液相化学组成,caofeosio2 ,补炉炉温1300 -1500度,利用混合料与渣的充分接触,稠化,冷却炉渣,使炉渣包裹混合料,粘在大面上,起到保护作用,同时,矿物之间成分相互扩散形成整体,达到补炉效果。Mgo-cao混合料,成本优势明显,使用寿命接近正常镁碳质修补料,mgo-cao混合料,不与炉渣发生剧烈氧化反应,危险性低,材质接近炉衬砖氧化物成分,易于烧结,无有害成分,对品种钢的生产无影响。

 

BOF large surface repair new technology, mgo-cao repair material

At about 1400 degrees, the main minerals in the mixture include: calcium silicate, calcium calcite, brucite, ferrous oxide, magnesium olivine, liquid chemical composition, cao,feo,sio2, furnace temperature 1300-1500 degrees, using the mixture and slag full contact, thickening, cooling slag, so that slag wrapped mixture, adhere to the large surface, play a protective role, At the same time, the composition of minerals diffuses to form a whole, to achieve the effect of filling furnace. Mgo-cao mixture, the cost advantage is obvious, the service life is close to the normal magnesium carbon material repair material, the mgo-cao mixture, does not have the violent oxidation reaction with the slag, the danger is low, the material is close to the lining brick oxide composition, easy sintering, no harmful composition, No effect on the production of variety steel.
