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:Is fireclay brick acidproof? Does clay brick anti corrosion when it's used to build chimney lining?
Refractory bricks anti acid and alkali after high-temperature calcination, and anti-corrosion won't be a problem
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: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
Q:Can thick steel plate be used instead of the furnace inside the refractory brick?
It depends on the temperature. The steel plate is a kind of heat conduction material which hasn't heat insulation, which should be based on the working environment.
Q:which kind of refractory bricks do coke oven and oxtongue brick belong to ( ) A, silica brick B, clay brick C, high alumina brick
General use clay bricks, but the silica brick is better, the price is expensive.
Q:what is consequence of high load and soft low of high alumina refractory brick ?
softening, if not up to the design requirements, may cause vicious incident like the collapse of the stove in use. the full name is softening temperature under a fixed load, as the name suggests, it is the softening temperature after adding the load.
Q:What is the meaning of the new type of dry rotary kiln refractory brick 620,320?
It should be the length of the turn. I'm not sure if it is right.
Q:Blend 12% fireclay and 88% refractory cement. Moderate water and mud are used to pile up firebricks?
If the temprature is below 1200 degrees, the clay castable refractory can be used at what temprature, or use lightweight clay thermal insulation bricks. Thus, the furnace body is not easy to crack. The service life will be long.
Q:What kind of refractory brick is used for industrial furnace?
High aluminum in cement plant. Mills use MgO-C, high aluminum ect; glass furnaces use Luo 8. different kiln and parts use different bricks.
