There are many types of high alumina bricks, including special grade, first grade high alumina brick, second grade high alumina brick, and third grade high alumina brick. Of course, the price of special high-alumina bricks is the best, and the aluminum content is the most. Today, I will introduce the production process of the next special high-alumina bricks: the production process of high-alumina bricks and multi-clinker clay bricks are similar, but the difference lies in the clinker in the ingredients. The proportion is relatively high, which can be as high as 90-95%. The clinker needs to be sorted and sieved to remove iron before crushing. The firing temperature is relatively high. For example, when high alumina bricks such as I and II are fired in a tunnel kiln, they are generally 1500~1600 degré .
Pratique ya production na Chine e prouvé que avant crushing, clinker ya aluminium ya likolo ezala strictement classé mpe classifié, mpe ebombami na ba niveaux. usage ya bauxite clinker na méthode ya grilles fine ya mabele ya lima ekoki ko améliorer qualité ya produit.
Propriétés mpe bosaleli ba briques ya alumine ya likolo ezali na refractoriness ya likolo, résistance makasi na érosion ya acide mpe alcaline ya ba slags, mpe makasi ya mécanique ya température makasi, yango wana esalelamaka mingi na industrie métallurgique mpe na ba fours mosusu.
Densité ya ba briques ya alumine ya likolo ezuami engebene na ntalo. densité générale ezali kati na 2.3-2.5g/cm3. soki densité ezali likolo, ntalo ekozala ntalo mingi. ba briques ya alumine ya likolo ya grade ya liboso mingi mingi esengaka koleka 2.4 na industrie, mpe ekoki.
Ba briques ya alumine ya likolo ekabolami na ba grades minei engebene na contenus ya aluminium. Contenu ya aluminium ya ba briques ya aluminina ya likolo ya niveau ya misato ezali na se ya 55% te, ba briques ya alumina ya likolo ya niveau ya mibale ezali na se te na 65, mpe ba briques ya niveau ya liboso ya alumina ya liboso ezali na se te. na 75 ya likolo ya likolo ya 75. Ba briques, en plus ya ba briques standard ya alumine ya likolo, ezali pe na ba briques ya alumine ya likolo ya générale, oyo babengaka pe ba briques ya alumine ya likolo oyo ezali na forme spéciale. soki forme ezali très irregulière, mbala mingi babengaka yango ba briques spéciales ya alumine ya likolo{14}} na mokuse, selon usage spécifique ya fulu ya kosala commande{15}}
