Q:What are the application of used refractory brick pieces?
It can be produced into refractory bricks again, as long as the quality is good. It is much more cost-effective than buying Bayerite.
Q:can castable refractory replace refractory bricks in rotary kiln?
depend on where you use, rotary kiln is not a good place to use it. it can repair the kiln.
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:Can refractory bricks be used to pave roads or build a wall?
Refractory bricks are used to build a house, no problem
Q:What is refractory brick? What is refractory clay? ?
Fire clay refers to the light pouring material, raw materials adopt light porous clinker, bauxite, cenosphere, silicon dioxide ultrafine powder and alumina micropowder. Use calcium aluminate cement CA-80 as binder. Refractory brick is burned from stone powder and clay put in 1300 degrees' kiln
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:The making process of clay brick
Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks. In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.
Q:Can refractory be used to sharpen knife?
Many factories build a smelting furnace by using this kind of bricks. A special knife grinder can be used to sharpen knife, can on 1. They are sizing and non-sizing refractory bricks respectively. Refractory brick is now a lot of fields and industry will introduce one of the raw materials. Products are divided into two different types, refractory brick as a high temperature resistance of the raw materials. In simple terms, working temperature is 770 DEG C, 580 C and 1, of course, refractory bricks also can be used to sharpen knife, use smooth brick to sharpen, need to choose high hardness
Q:can the red brick be used as refractory brick?
Can not replace! The high temperature will make it burst. Coefficient of thermal expansion is not enough
Q:is it correct that the higher the refractoriness is, the better refractory bricks are?
Does not necessarily, it has a great relationship with the compression and bending and corrosion resistance.
