EAF Refractories

High Alumina Brick High alumina brick is a kind of neutral refractories. It is manufactured from bauxite or other refractory raw materials within high alumina formed by molding and calcination. High aluminum refractory bricks has high refractoriness, high load softening temperature, thermal shock stability, good slag resistance, acid, alkali, peeling resistance, erosion resistance and so on. High alumina brick is mainly used for electric furnace top, blast furnace, hot air stove, ladle, cement kiln, glass kiln and other thermal furnace lining. High alumina brick is widely used in iron, steel, chemicals, cement and other industries.

Silica Ramming Mass Silica ramming mass also known as acidic ramming mass.The raw material of silica ramming mass is high quality quartz, mixed with high quality boric acid. Silica content of its raw material is more than 99%. Generally we will add 1 % to 1.5 % to premix with quartz, but it can be changed as per customers’ requirements. Silica ramming mass is one of the most popular products in our company. Plays a crucial role in induction furnaces during melting of steel. This substance is used to line induction furnaces and its quality decides smooth working and more efficient output from the furnace. Our monthly production capacity is 10,000MT/month. Advantages of Silica ramming mass: High erosion resistance. High bonding strength. Free engineering services to guarantee service life. Does not expand or shrink with temperature changes Article source: http://www.ruizhirefractory.com/en/product/silica-ramming-mass.html Email: sales@ruizhirefractory.com

Optimize the furnace campaign The magnesia carbon brick at the door of the furnace is the weak point of the closed-loop masonry of the furnace wall. Magnesia carbon bricks will have a large thermal expansion after undergoing smelting high temperature, and will be released in the doorway area to make the magnesia carbon bricks arch. For this reason, when adding magnesia carbon bricks at the door of the furnace, by adding special materials, a 1-2mm brick joint is reserved to meet the expansion space between the magnesia carbon bricks and eliminate the thermal expansion effect. The furnace door electrode is used to fix the furnace door brick, which is convenient for slag cleaning. The graphite electrode is used in traditional masonry. Because of its short burning life, it is replaced by steel water-cooled analog electrode, which solves this problem and saves the service life. Can reach more than 2000 furnaces.

Neutral Ramming Mass Neutral ramming mass is able to resist penetration & protrusion of cracks & pores into the refraction lining, thus providing safety from penetration of molten steel towards the heat sensitive crucible & neutral ramming mass also ensures easy removal while replacing the lining. With a specific ability of sintering only on the surface, that is in contact with the molten steel. Neutral ramming mass has a series of advantages such as erosion resistance, strong stability, non-cracking, strong operability and high fire resistance.

Magnesia chrome brick is made of some preliminary synthesis high purity raw materials. The high purity raw refractories should be high pressure formed, ultra high temperature fired and then go through some other post-treatment process and system, finally made the magnesite chrome brick. Magnesia chrome brick has high room temperature compressive strength, low porosity, strong erosion resistance and scouring resistance, etc. Usually it is used for bottom part of VOD.
