Mullite insulation brick is made of high-alumina bauxite clinker as the main material, plus a small amount of clay or raw bauxite as a binder, and then shaped and sintered at high temperatures.

Lightweight clay insulation bricks are high-quality insulation materials. It can be used in the kiln to achieve rapid heating and cooling, reduce the weight of the furnace body, save fuel, and reduce production costs.

High alumina refractory brick is a silicic acid refractory material, the softening temperature under load is 1420-1550°C, and the load temperature will increase with the increase of the ratio of aluminum to silicon.

Magnesia carbon brick is made of magnesia and carbon materials, and various non-oxide additives are added. Magnesia carbon brick is a kind of basic refractory material. As a composite refractory material, magnesia carbon brick effectively utilizes the slag erosion resistance of magnesia and the high thermal conductivity and low expansion of carbon.

High-alumina castable is an amorphous refractory material composed of bauxite clinker (aggregate), binder, and admixture. It can be used directly after adding water and stirring and is formed by vibration casting. High-aluminum castables need a certain amount of time for setting and hardening after construction, so they need to be cured for a certain period before they can be de-molded after casting.

Low and ultra-low Cement Castables have the characteristics of small pore size, large density, good volume stability, high strength, and a small amount of water. They overcome the characteristics that the strength of ordinary castables decreases significantly at 800~1200 ?, increases with the increase of temperature, and have excellent thermal shock resistance, slag resistance, and corrosion resistance.

Refractory mortar is made into new type inorganic binder materials by choosing the same powder materials, adding inorganic binder, according to request of construction materials. There are four grades as below NT-1300,NT-1400,NT-1500,NT-1600,each material is divided into light weight and heavy weight,we can choose relevant refractory mortar according to different request of construction material.
