Fire/firecaly brick

 

Refractory brick is dense shaped refractory material. With high refractoriness and mechanical behavior under high temperature, refractory brick is the necessary material of high-temperature services, mainly used for industrial furnaces and kilns and thermal equipment.

 

Refractory brick has wide applications, mainly used in metallurgy, construction(cement and glass), petroleum, chemical industry, electric power and machine building.

 

Linquan series alumina bricks are high quality dry pressed alumina bricks, ranging from 35% to 95% in alumina content.

Q:What are the alloy wear resistance materials?
KNMn19Cr2 (patent) high manganese alloy (ZGMn13Cr2MoRe), super high manganese alloy (ZGMn18Cr2MoRe); two: anti-wear chromium cast iron series: such as high, medium and low chromium alloy cast iron (Cr15MOZCu); three: wear resistant alloy steel series: such as, low and high carbon multi metal combined steel (such as ZG40SiMnCrMO and ZG35Cr2MoNiRe); four: ADI (ADI) series; five: all kinds of composite or gradient material and hard alloy materials, nano KN alloy (patent product): such as chromium carbide composite (Cr2C3+Q235), high-energy ion osmosized tungsten carbide materials (WCSP), high toughness of cemented carbide (YK25.6), KN999 nano alloy (Beijing Naimo patent) etc.;
Q:What are the high aluminum bricks made of?
We specialize in the production of various LeiBao refractory refractory material, such as corundum, zirconia products, alumina hollow ball products, mullite products and so on.
Q:How much is the bending temperature aluminum silicon carbide brick for torpedo car
High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.
Q:What is the heat preservation material used in a laboratory furnace?
Silicon carbide (SiC) is made from quartz sand, petroleum coke (or coal tar), sawdust (green salt produced when adding green silicon carbide) and other raw materials by smelting with resistance furnace at high temperature. Silicon carbide also rare minerals in nature, Mo sangshi. Silicon carbide, also known as carbon silica. Silicon carbide is the most widely used and the most economical kind of refractory materials in C, N, B and other non oxide refractory materials. It can be called "carborundum sand" or "refractory sand".
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.
Q:Does the chimney have high acid resistance?
The acid resistant bricks used for chimney are usually made of custom-made trapezoidal acid proof bricks, and the physical and chemical indexes of acid resistant bricks need to be confirmed according to the chimney's actual emission. At this point, you can consult our kerei refractories.
Q:The difference between aluminium refractory and magnesia refractory
Magnesia refractory belongs to alkaline refractory materials refers to refractory products such as magnesia magnesia brick magnesium iron spinel magnesium aluminum spinel magnesia ramming materials and other products of raw materials is the main crystal phase is periclase magnesia products
Q:Corundum, high alumina and fireclay refractory difference is what
They differ in that the alumina content is different, and the content is in order: corundum > high alumina > clay.
Q:What are the categories of bricks?
Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels.
Q:How high can aluminum bricks expand at 80O degrees of heat?
The expansion of high alumina brick is not only related to temperature, but also related to its material composition. The refractory temperature of high alumina brick is above 1770 centigrade. The temperature of 800 DEG C has little influence on the expansion of high alumina brick.
