Q: What is fireproof concrete?: Silicate fireproof heat-resistant concrete using temperature can reach 700 DEG ~800 DEG, the main mechanism of its heat is dehydrated calcium hydroxide silicate hydrates series of cement clinker under high temperature, the calcium oxide and slag and mixing activated silica material in the three and two aluminum oxide and the reaction of anhydrous calcium silicate and anhydrous aluminum acid calcium has strong heat resistance, the fire resistance of concrete is a certain. Such as the use of high alumina bauxite and broken bricks, magnesia brick and magnesia for fireproof heat-resistant concrete materials with the highest using temperature can reach 1100 DEG C.

Q: What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?: The brick Pei boring and time. 6, Pei brick kiln installed between the brick and the brick Pei order, Pei and kiln top, kiln wall gap etc.. 7, high alumina brick kiln plan, and the lack of edges and corners of the scene should be avoided.

Q: What are the common thermal insulation materials for thermal conductivity?: Aerogels are known to be the lightest solid materials in the world. It is made of nanometer silica aerogel as main material and is compounded by special process. The utility model has the advantages of high temperature resistance, low thermal conductivity, small density, high strength, green environment protection, waterproof and non inflammable performance. At the same time, with excellent sound insulation and shock absorption performance, it is now widely used in metallurgy, chemical, national defense, aerospace and other fields, is an indispensable high-performance insulation materials.

Q: What is the density of a super high alumina brick and what is the price?: Of course, the transaction price, please choose refractory brick manufacturer is better.

Q: Difference between low creep high alumina brick and ordinary high alumina brick: The emphasis is on the physical and chemical indexes of low creep and high alumina bricks. The physical and chemical indexes of the high alumina bricks are different, too. They are DRL-1550And LZ-75 perform GB GB/T2988-2012

Q: What are the characteristics of high alumina bricks?: A neutral refractory with an alumina content of more than 48%. Made from alumina or other raw materials of high alumina content; formed and calcined.

Q: What's the weight of the refractory bricks?: Fireclay refractory bricks: 3.4kg-3.8kg - according to the quality of raw materials, prices ranging from 1 yuan to 2.7 yuan, high alumina refractory brick: three, high aluminum in 3.9kg or so. Ordinary T-3 firebrick weight calculation method: 230*114*65*2.2/2.1.

Q: What is the difference between high alumina brick and clay brick?: Light clay brick, refractory material is a kind of high porosity, low density, low thermal conductivity of refractory material, refractory materials called lightweight refractories, it includes insulating refractory products, refractory fiber and refractory fiber products. Heat insulation refractory material is characterized by high porosity, general 40%-85%, low volume density, lower than 1.5g/cm3, low thermal conductivity, generally lower than 1.0W (m.K). The utility model has the function of heat insulation of an industrial furnace, and can reduce the heat dissipation loss of the kiln, save energy, and can reduce the quality of the thermal engineering equipment. The mechanical strength, wear resistance and slag resistance of insulating refractory material are poor, and it is not suitable for the load-bearing structure of kiln and direct contact with slag, burden, molten metal and other parts.

Q: What is the apparent porosity of high alumina brick?: In the production of high alumina bricks in addition to the entity, there are many different sizes and shapes of different pores, pores can be divided into three categories: one side closed the other side and the outside world is called open pores, closed in the product not communicated with the outside is called closed pores, penetrating through pores called the few products.

Q: What is the difference between fireclay bricks and high alumina refractory bricks?: High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3.
