High Alumina EPS insulating Firebrick
Introduction:
This series of products are sintered mainly with supper-fine bauxite chamotte, and proper additive by a method of EPS ignition loss, Their main advantages include high intensity, low thermal conductivity, excellent thermal stability, very small reheat linear change, outstands erosion and corrosion resistance etc.
Advantages:
1. High strength
2. Optimum performance
3. Dimensional stability
4. Low thermal conductivity
Application:
They are an ideal kind of energy-conserning products which can be widely used as lining or insulating layers of various industrial furnaces and kilns in metallurgical industry, machine building industry, ceramic industry, chemical industry, etc. Recommended service temperature: Less than 1400C.
Clients can avail from us a wide variety of Fire Bricks, which is widely demanded for their high strength. The offered bricks are manufactured using high-grade material and advanced techniques, thus complying with the international industry standards. Our array of bricks is extensively used as lining in fireplaces, fireboxes, furnaces and kilns.

Characteristics of lightweight mullite bricks
Lightweight mullite brick Features:
1. Low thermal conductivity, low heat capacity.
2. High purity, impurity content less.
3. High temperature, direct contact with the flame.
4. High strength, and has excellent thermal shock resistance. Applicable to metallurgy, petrochemical, building materials, ceramics, machinery and other industries of various industrial furnace hot surface lining and backing. Heat treatment furnace, resistance furnace, tunnel kiln, roller kiln, bell kiln, glass tank kiln and so on. The Refractory company products are widely used in many industries, such as: cracking furnace, reformer, heating device, refining device, regenerating device, hot air furnace.
Features:
Higher refractoriness, up to 1790 ℃ or more. The softening start temperature of the load is 1600 to 1700 ° C. Room temperature compressive strength of 70 ~ 260MPa. Thermal shock resistance is good. There are sintered mullite bricks and fused Mullite Insulating Firebrick. Sintered mullite brick to bauxite clinker as the main raw material, adding a small amount of clay or bauxite as binder, by molding, firing and made. Fused mullite refractory brick to high bauxite, industrial alumina and fireclay refractories as raw materials, by adding charcoal or coke fine particles as reducing agent, forming after the use of reduced melting method to manufacture. The fused mullite is more crystalline than the sintered mullite and has a better thermal shock resistance than the sintered product. Their high temperature properties depend mainly on the alumina content and the homogeneity of the mullite phase with the glass distribution.
