Tunnel Kiln Produce Refractory materials High Fireproof Fire Clay Brick With Factory Price
Raw Material Selection
To ensure the quality of our raw materials, we only purchase our raw materials from our long-term trusted suppliers. With every purchase, the raw material must be passed 2 times inspection, 1 time at our supplier's site. a second inspection on the batch after the material arrived to our factory. Each time raw materials enter our facility, they are inspected again prior to being accepted.

Rotary kiln refractory brick, also called kiln brick, is a layer of refractory material filled inside the kiln cylinder. Its main functions are:
1. Reduce the chemical corrosion and mechanical wear of the high temperature gas and materials on the cylinder and protect the kiln shell.
2. Acting as a heat transfer medium The kiln brick can absorb a part of the heat from the gas and transmit it to the material in different conduction and radiation ways.
3. Kiln bricks can also be insulated and heat-reduced to reduce heat loss in the kiln.
So The refractory brick is a critical component in ensuring process efficiency and prolonging the life of a rotary kiln.
Product Advantages
1). Water permeability
ZJT brick has super high permeability function, more than 20mm/s which is two times of the standards of similar foreign products. It can handle 60mm/s rainfall. The road and squares paved with it can make rainwater quickly penetrate down to prevent the occurrence of city flood.
2). Water retention
It can be used to reduce the temperature of the environment, restore natural water storage capacity, prevent the depletion of groundwater, and improve the living environment of vegetation.
3). Skid Resistance
Rainwater infiltrates into the ground timely. There is no water. Keep the ground clean. Walking on it brings no danger. Used in public or family kitchen and bathroom floor, it exerts excellent anti-skid effect.
4). Noise Reduction
Porous structure can absorb the vehicle noise, and create a quiet and comfortable environment. It have been widely used in foreign countries in airports, subway and other places.
5). Repeated use
Because of the characteristics of product in the design, it can be used repeatedly, reducing waste in construction of city and the waste of various resources, and produce good economic benefit and social benefit.
6). Compression-resistant, Cold-resistant, weathering-resistant
Made by large tonnage press and high temperature firing. The compressive strength is ≥ 50MPa, suitable for use in the parking lots, common lanes. Its frost resistance value is -25º C.
7). Low carbon emission and environmental protection
Long product life and weathering resistance can bring infinite times repeated recycling.
Lightweight insulating brick properties & advantages :
1. Low levels of iron and other impurities;
2. High mechanical intensity;
3. High refractoriness, can contact with the flame directly, suitable for various atmosphere;
4. High porosity, low volume density, low thermal conductivity;
5. Good heat insulating performance and energy-efficient;
6. Low creep rare at high temperature,good thermal shock stability;
7. Chemical corrosion resistance;
8. Long service life.
Application of Lightweight insulating brick:
Mullite insulation bricks can be in direct contact with the flame.
Mullite insulation bricks can be used as linings or as thermal preservation layers in various industrial furnaces and kilns in metallurgical industry, ceramic industry, chemical industry, machinery industry, such as blast furnace, hot blast stoves ,electric arc furnace, cement kiln,melting furnace, ignition furnace, flue, refining equipment, heating equipment and piping, regeneration device, gas furnace, soaking furnace, annealing furnace, heat reaction chamber and other thermal industrial equipment.
