High Alumina Bricks for general uses are made from bauxite of super quality, bonding chamotte and additives. It is noted for good erosion resistance high refractorinessthermal shock resistance and accurate dimension. They were widely accepted in various kilns ,thermal equipment of metallurgy, petroleum, chemical industrysuch as high aluminum bricks for blast furnaces steel ladle and electrical furnace and so on .
1. Low bulk density, low thermal conductivity, good thermal insulation performance.
2. Refractory category allow direct contact of fire, suitable ofr various atmosphere
3. Good integrity with furnace lining, long service life, easy operation, could be shaped freely
4. Can be used in various kilns because of its cheapness and general tray package.
Applications
1. Furnaces of metallurgy industry, heat treatment furnace
2. Furnaces of chemical industry and construction industry.
3. Furnace of incineration of garbage, recirculating fluidized bed furnace

Cement Brick
Mmw cement brick & block machine model cbm300 is a automatic operations machine ( use man only for loading of raw materials and unloading of finished bricks / blocks / pavers ). It is hydraulically operated and uses vibration & hydraulic compaction to form cement bricks, hollow blocks and pavers. It is completed with sand hoppers, belt conveyors, mixer, automatic wooden plank loader, touch screen controller, chain conveyor and gantry cranes. Moulds of various designs and dimensions can be fabricated according to customersf+ specifications and requirements.
Magnesia carbon brick isprepared by using high grade fused magnesia and big crystal flake graphite as raw materials,adding compound high efficiency antioxidant and additives,after appropriate grading, moulding and heat treatment process.They are characterized by good oxidation resistance,slagresistance and thermal shock resistance.
It can be applied in different parts of steel making equipment,such as converter, electric furnace, refining frnace and ladle.
1) Super-strong steel structure made of extensive imported original parts, ensuring more stability and reliability for the main machine body.
2) The whole process uses a PLC aptitude control and dialogue system of human-machine interface, easy to analyze the chance signal, ensure the best operation effect.
3) High-efficient and super-strong vibration system, computer-control flow pressure of the hydraulic system, realize vertically synchronous vibration, frequency conversion, and braking, with synthetic output compounded with double vibration sources, thus greatly increase product compactness and mold-box service life.
4) The cloth system adopts semi-closed screen reticular rotational feeding unit to feed materials forcedly, with evenness and even speed, ensuring product intensity.
5) Fitted with special hydraulic loading unit, readily realize mass and automatic production, saving a great deal of human power, maintenance field, and circulating fund investment.
