System for preparing steel slag sintered bricks
The invention discloses a system for preparing steel slag sintered bricks. The system is characterized in that: pretreating steel slag through a first ball milling mechanism, grinding the steel slag into steel slag powder with a particle size of smaller than or equal to 0.045 mm, and subjecting the ground steel slag powder to ageing treatment and moisture drying; putting into a placing chamber; and grinding ferric oxide powder in the first ingredient through a second ball milling mechanism, mixing the ground ferric oxide powder and steel slag powder in a first mixing chamber, and then adding silicon powder and argillaceous aggregate. The perfection of ferrite crystallization is further promoted in that the melting point and the dynamic temperature of the mixture are reduced, so that the mass transfer and heat transfer conditions of a liquid phase are improved, the crystallization of minerals such as ferrite and the like can be promoted,the realization of low-temperature sintering of steel slag bricks is facilitated, quicklime is added while the steel slag bricks are mixed and put into a third mixing chamber, and hydration and hardening are promoted to improve the compact strength of brick structure. After the mixture in the third mixing chamber is subjected to blank making and standing for a period of time, the mixture is fed into a calcining kiln to be sintered, and the produced steel slag sintered bricks have the characteristics of high strength and good air permeability.
本发明公开了一种制备钢渣烧结砖的系统,通过第一球磨机构对钢渣进行预处理,将所述钢渣研磨≤0.045mm的钢渣粉末,将研磨后的钢渣粉末进行蒸化处理,烘干水分;放入到放置室;通过第二球磨机构对配料一中的氧化铁粉进行研磨,将研磨好的氧化铁粉与钢渣粉末在第一混合室混合,然后加入硅粉和粘土质骨料,进一步促进铁酸盐结晶完善在一定程度上是由于降低了混合料熔点和动温度使液相增加传质传热条件改善,能促进铁酸盐等矿物结晶完善有助于钢渣砖低温烧结的实现,在混合放入到第三混合室同时加入生石灰,有利于水化硬化提高砖结构密实强度,将第三混合室中混合物进行制坯,静置一段时间后,送入的到焙烧窑中进行烧结,产生钢渣烧结砖具有强度高,透气性好的特点。
