Q:does the furnace wall use refractory bricks to keep the heat? Or use the insulation material to keep heat ?
The furnace arch and the furnace wall are all refractory bricks, and the refractory brick is a kind of thermal insulation material!
Q:what kind of refractory brick is suitable for 1300 degrees converter?
magnesia-carbon brick, you can also use MgO-Al2O3 castable, it is good too.
Q:What is the main use of refractory brick?
Almost all high temperature furnace needs of the needs refractory bricks, such as blast furnace for iron smelting, high temperature differential thermal analyzer also use it, refining furnace, converter for steelmaking, muffle furnace, electric furnace and drying equipment. the uses are wide
Q:In tunnel kiln, what is the meaning of refractory proportion 2.0?
That is the volume density of the refractory brick
Q:How to count the number of loading refractory bricks?
Use one meter by one meter wooden raft-towing: use one meter raft-towing to count: Known your brick is T-3 standard bricks, each four layers lies down 15 and sidewards is 4 =64; according to 3.4kg, 47 clay bricks can hold 10 to 12 layers. According to the upper limit, each raft-towing can hold 2.3 tons
Q:What is the refractory brick in silicious model?
Adding appropriate amount of mineralized agent to promote the transformation of quartz in the body into phosphorus quartz. Smaller coefficient of thermal expansion. Also used in high temperature bearing part of hot blast stove and acid open hearth furnace, refractory materials and ceramic kiln, kiln vault and other load-bearing parts, thermal shock resistance variation. High temperature strength. the glass furnace is burnt in 1430 to 1350 degrees Celsius in the reducing atmosphere. use natural silica as raw materials. True density 2. more than 93% of silica content. generally there is no crystal type transformation above 600 degrees celsius. With acid slag erosion and sediment chamber regenerator performance, soaking furnace, open hearth furnace. there is more crystal type transformation below 600 degrees celsius. mainly used in coking chamer of coke oven and partition of firebox. acid refractory material made of high thermal shock resistance, large volume change, square quartz and a small amount of residual quartz and glass box . Long term use at high temperature without deformation
Q:How many pieces of porous brick is equal to one ton?
Refractory bricks are generally classified into two types, that is, shapeless refractory materials and shaped refractory materials. Shapeless refractory material: Also known as castable refractory, is hybrid power material composed of a variety of aggregate or a kind of aggregate and one or more kinds of the mixture of adhesive particles, it should be used evenly mixed with one or more kinds of the liquid, which has strong liquidity. Shaped refractory material: The general making of firebrick, there are standard rules for the shape, can also temporarily process according to need of building and cutting. The following are the specifications. fireclay bricks 230*114*65 each block 3.0 - 3.6 kg; special-shaped fireclay brick 230*65/55*114 each block 2.8 - 3.3 kg; the reason for the weight's ranges is that because the quality is different, in general, heavy density, good quality!
Q:What is common brick, firebrick and hollow brick?
Mainly used for smelting furnace and silica brick. There won't be problem by using scientific methods. Refractory brick----is refractory material with a certain shape and size. According to the preparation process, can be divided into firing brick. Similarly. Hollow bricks are very scientific in use. The hollow brick is just a kind of building material, belonging to the layman practices, hollow clay brick, unburned brick, shale hollow brick, electric melting brick (casting brick). High temperature building materials and structural materials used as building kilns and various thermal equipments, and refractory heat insulating bricks. Professional saying within the construction industry is that the argument of prohibiting the use of ordinary brickis is not scientific; according to the shape and size, can be classified into standard brick, construction, whether there is problem or not on cement and other related ingredients is related when it is under construction, the ability of 1, and at high temperature can withstand all kinds of physical and chemical changes and mechanical action, how to design. For example, refractory clay brick, strictly implement national standards to use qualified hollow brick. 8 earthquake, high alumina brick , magnesia brick, etc. due to the security risks. Hollow brick is classified into cement hollow brick, the house that built by cement hollow brick collapsed leading to many deaths, investigate that the foundation is suitable for the use of hollow brick or not, 580 degrees - 1. Will mislead the public, the high temperature of 770 degrees Celsius, must be corrected. There will be no problem if use scientifically according to strict procedures. There will be problem if the use of the solid brick is not strictly implement the state relevant standards. Also called refractory brick, special-shaped brick and etc. Refractory material made from refractory clay or other refractory raw materials
Q:What are the type, location and the physical and chemical effects of the refractory brick used in the cement rotary kiln?
And T209
Q:What is the advantage of the ceramic fiber material compared with the refractory brick?
Ceramic fiber material is heavier than refractory bricks, property of machinery operation, low heat capacity, and has high anti-stretchability and good thermal shock resistance, low thermal conductivity make its thermal insulation effect is ten times than refractory brick, it won't has crack in sudden coolness and heat, and the construction is much easier than that of refractory brick, not delaying the production.
