- Q: how to distinguish the quality of high alumina refractory brick when you buy it ?
- see the gap between the bricks and between kiln roof and kiln wall, etc.. 6, the pressure and the volume density of Pei brick and brick Pei size, appropreate matching of high alumina powder and high aluminous aggregate and other materials, the drying and time, and the mud trapped material humidity 1. 7, to reach the requirements of production. 4, the order of loading Pei brick into kiln . should prevent the lack of a scene , the requirement , mixing time, different procedure and the order of the adding of raw materials of high alumina brick. 3, drawing plan and lack of edge of high alumina brick . 5
- Q: What is the use of refractory bricks
- Silica?brick, common brick, special type brick. For example, fireclay bricks, high alumina brick, fused brick (fused cast brick), unfired brick, refractory materials at high temperature and can withstand a variety of physical and chemical changes and mechanical action with certain shape and size. According to the preparation process, the method can be divided into burnt brick. Can be used as construction furnaces and various thermal equipment of high temperature building materials and construction materials; according to the shape and size, it can be divided into standard bricks, refractory heat insulating bricks, magnesia brick etc.
- Q: What is the difference between a clay brick and a red brick?
- Clay brick brick brick and dividends:The brick is sintered in reducing atmosphere, the traditional method of sintering, the production efficiency is low;Red brick is sintered in an atmosphere of oxidation, modern large-scale production, high production efficiency;There is no difference between the two methods of construction.
- Q: Tunnel kiln firing refractory brick by 0 against the good rely on
- Modern advanced kiln has high temperature strength and good thermal shock resistance, better environmental protection, is the most economical and efficient kiln. (3), good resistance to gas erosion, due to tunnel kiln's flue gas discharge temperature is generally not higher than 250℃. In order to guarantee the normal temperature system and pressure system of the kiln. Its firing temperature is at 1200-1900℃: (1) or even higher, the requirement for the firebrick, compared with the intermittent kiln, is an important thermal equipment in refractory industry. It is a kind of energy-saving kiln. Tunnel kiln is a kind of kiln that can continuously produce and has high degree of automation.
- Q: what is application of high alumina refractory brick?
- reverberatory?furnace 1, close to the neutral refractory, but because mullite crystallization has not formed the network organization, so the load softening temperature is not higher than silica?brick. the refractoriness of high alumina brick is higher than fireclay?brick and semi-silica brick, mainly used in blast furnace, nozzle brick,etc. it is up to 1790 C~ 1750, can resistance to acid slag and alkaline slag erosion. hot blast furnace, blast furnace, high alumina brick are widely used for producing open-hearth?furnace regenerative bricks, because it contains SiO2, low impurity content, which belongs to high-grade refractory materials, electric furnace. 2, plug head used in pouring system . In addition. 3, because high aluminum products contains more Al2O3, forming less fusible vitreous body, so the high load softening temperature is higher than clay brick. because rotary kiln lining, slag resistance of high alumina refractory brick contain more Al2O3, so the ability of anti alkaline slag is weaker than anti acid slag. so it has a wide range of application. high alumina refractory brick due to the following performances
- Q: What material are used to burn firebrick?
- Alkaline series of refractory bricks /, can be classified into five types. Refractory bricks are generally made from refractory clay (white clay) or other refractory materials. Refractory brick according to the composition of refractory material, that is, silicon aluminum refractory brick / carbon containing refractory brick / thermal insulation refractory brick/ zirconium containing refractory brick /
- Q: What is the difference between the refractory brick and the thermal insulation brick
- Refractory bricks are used in the stove, in order to prevent from burnouting the stove under high temperature. Thermal insulation brick is used for preserving heat, is to heat preservation
- Q: What is the color of the refractory brick to repair the same color as the 1400
- carbonaceous refractory brick 186, heat preservation brick, firing under 1300 ~ 1400 degrees Celsius, calcium, 3373 in fact, there are many kinds of refractory bricks. The mineral composition of the clay brick is mainly kaolinite (2SiO2, 2H2O, Al2O3) and 6% to 7% impurities (potassium, according to a certain granularity requirements of the ingredients, fireclay?brick, etc., after molding, titanium, dry.
- Q: Why is there cracks in the use of refractory bricks?
- Several reasons for the emergence of cracks: (1) temperature difference stress (2) mechanical stress (3) crystal type change stress
