Products and Introduction

Name of products Remark
Fireclay brick Alumina-silicate products containing 35~48% of Al2O3 and in a certain shape,is called fireclay brick, widely used in blast furnace, thermal storage comber, soaking pit, annealing furnace, ladle,etc.
High alumina brick Alumina-silicate products containing more than 48% of Al2O3 and in a certain shape,is called high alumina brick, widely used in blast furnace, thermal storage comber, soaking pit, annealing furnace, ladle,etc. High alumina brick containing more than or ever more 80% of Al2O3 is used in electric arc furnace roof and the special zone of other high temperature furnaces.
Magnesite brick Magnesite brick made from densely sintered magnesia clinkers at temperature, containing more than 87% of MgO with the main crystical phase of periclass, is sintered magnesia brick. Magnesite brick is strong basic and high grade product with a good resistance to basic slag corrosion and refractoriness over 2000°C. The product is mainly suited to steel open hearth furnaces, steel electric arc,torpedo, the basic zone of ferrous metal furnaces.
Magnesia -alumina brick Magnesite-alumina brick manufacture from a great number of MgO and the number of Al2O3 , it is basic refractory material. It has an advantage over general magnesite brick in high temperature strength, slag resistance, due to containing more highly fused mag-spinel in matrix and little impurity. Its thermal stability is better than general magnesite brick. So it is called thermal shock resistance magnesite brick. It is mainly used in steel open hearth roof, nonferrous metallurgical furnace, rotary kiln, high temperature tunnel kiln.
Magnesia -chrome brick The brick made from sintered magnesia clinkers and chrome ore,sintering at high temperature 1600°C is named sintered magnesia-chrome brick. It is usually called magnesia-chrome brick. The refractory, contains MgO 50-70%,Cr2O3   8-16%. It has good specifications in stability, high temperature constructure strength,resistance to basic slags, resistance to acid (better than magnesite brick) and refractoriness 2000°C .The brick is extensively applicated innonferrous furnane,steel electric arc, steel open hearh, converters, torpedo, vacuum treatment unit,burning zone of cement rotary kiln, thermal storage comber of glass kiln.
Direct bond magnesia -chrome products The brick made from sintered magnesia clinkers, chrome ore and fused magnesia-chrome ,sintering at high temperature 1800°C is named direct bond magnesia-chrome brick.The refractory, contains MgO 60-70%,Cr2O3   8-20%. It has good specifications in stability, high temperature constructure strength,resistance to basic slags,The brick is extensively applicated innonferrous furnane,steel electric arc, steel open hearh, converters, torpedo, vacuum treatment unit,burning zone of cement rotary kiln.
Magnesia -carbon  products The brick is made in presure from dead burned magnesia (or fused magnesia) and carbon material (full-crystal graphite) with the binder of pitch and resin. Magnesia-carbon brick at high temperature forms combination of carbon frame. Magnesia and carbon can't be fused each other. So it keeps their properties good . In addition, carbon has a better thermal conductivity. Both of high expansion and spring coefficients are low. It can effectly resist to thermal flaking,slag corrosion and constructure flaking. Carbon has no wettability to slay, so resistance to corrosion is good. The brick is widely applicated in steel electric arc, combined blowing converter, ladle, torpedo, refined ladle furnace, ect.
Alumina -magnesia -carbon  products
Unfired magnesite products
Unfired magnesia -chrome products
External plating unfired magnesia -chrome products The brick, made from mixture of magnesia and chrome ore by process of moulding directly, packed tightly with iron sheep is called external plating unfired magnesia-chrome brick.  Its size and chemical content can be regulated according to the needs of customers. The product is applicated in thermal spots of steel electric arc lining. burning zone of cement rotary kiln,etc.
Fused silica submerged nozzle The nozzle are made of fine fused silica raw material. They have a unique combination of advantages including low thermal conductivity high, mechanical strength, low thermal conductivity, excellent resistance to thermal shock and erosion.
