Refractory Low Porosity Fireclay Brick for Glass Furnace
High alumina fireclay Brick for Heating Furnace is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory, which has such advantages as high porosity, small volume density, good insulation effect, high mechanical intensity, small thermal conductivity and long service life. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.
This series of High Alumina fireclay Brick for Heating Furnace are made of selected high alumina bauxite, kaolin caly, hollow microsphere as the mian material.By shaping at high pressure and sintering at high temperature.
Fireclay brick is shaped refractory product.It is made from flint clay clinker and binder , Through high heat sintering. The Al2O3 content range from 28% to 48%.The refractoriness range from 1580°C to 1750°C(SK-30.SK-32.SK-34.SK-35).
High alumina fireclay Brick are ideal for use in the below applications
Furnaces of metallurgy industry, heat treatment furnace
Furnaces of chemical industry and construction industry.
Furnace of incineration of garbage, recirculating fluidized bed furnace
Standard sizing: 230 x 114 x 65 mm others up to the client

Q1: How about your factory’s annual production capacity?
A1:CMAX annual production is about 310,000Tons.
Q2: How many production lines of your factory?
A2:CMAX has 26 production lines, including eight silicon bricks lines, and each one of mullite brick, high alumina brick, insulating brick and monolithics line.
Q3:How large the scale of your factory?
A3: CMAX covers almost 200,000 Square meters, including plant area of 180,000 square meters.
Q4: What’s your factory’s product scope?
A4:CMAX main products are: refractory for hot blast stove, refractory for coke oven, refractory for glass kiln, refractory for carbon calcining furnace, refractory for acid pickling line, refractory for cement kiln, refractory for blast furnace, refractory for nonferrous metal furnace, and basic refractory raw materials.
In this stage massive raw materials which have been stored, are ground and classified into proper sizes, making them easier to shape.
The prescribed size of ground raw material is weighed and mixed into a designated amount of water and forming agent.
The mixture is then poured into a mold to form shapes, and the pressure is high.
In this stage water is removed from the shaped bricks. This helps preventing the bricks from deforming or cracking which may result due to the rapid evaporation
This is the most crucial process in refractory manufacturing. The modeled bricks are fired at high temperature to complete their thermochemical reaction so that they do not deform.
The bricks' physical and chemical properties are inspected very carefully by rigid quality management procedures.
