Bauxite is a naturally occurring mineral comprising mainly of aluminium hydroxides (the trihydrate Gibbsite Al(OH)3and the AlOOH monohydrate polymorphs boehmite and diaspore), with other components in the mineral typically being silica, iron oxide, titania and aluminosilicates (clay etc). It’s a rock from Laterite soil and it is a primary Ore of Aluminium. Properties of Bauxite include low iron content; a high Polished Stone Value (PSV) for high friction surfacing applications; a high melting point and density. APPLICATIONS Gunning materials High friction surfacing Minerals for abrasion Refractory castables Mouldable and Ramming Mixes Refractory mineral blends CEMENTATION believes in supplying quality bauxite with consistency to its customers across the world, according to their needs.
* PHOSCAST Phoscast : Phosphate Bonded Castables * PURPOSE customers using FBC boilers (Particularly underbed feed FBC boilers) for the protection of inbed coils against erosion potential by applying highly abrasive resistant refractory on inbed coils above fuel feed system. BACKGROUND * Two of such actions are providing special alloy studs on inbed coils and applying highly abrasive resistant refractory on the outer bottom loops of inbed Coils which are above the fuel feed nozzles. * GANESHAS has taken number of approaches to identify the key factors affecting erosion rates with an objective to enhance the life of inbed tubes as well as implementing the corrective action to reduce the erosion rates. Phosphate coatings are often used to protect steel parts against rusting and other types of corrosion * Erosion of inbed coils in fluid bed combustor is unavoidable phenomenon however the rate of metal wastage and thus the life of tubes depends on various factors like ash & fuel properties, design of Combustor / feeding system, flue gas velocities operating conditions etc. It has been also observed that maximum erosion prone inbed coils are those which come above fuel feed nozzles and an area of approximately 1 to 1.5 mts around fuel feed systems are badly affected. APPLICATION Phoscast-90 XR can be applied by ramming with wooden mallet having adequately large head @" dia x 5" length x 10â?? Jong handle). The desired lining or repair thickness is built up in several courses while ramming the mass to uniform thickness. Phoscast refractory should never be trawled to obtain smooth surface; ramming only should finish surface. Any excess mass is to be sliced off with trowel edge and then finished by ramming again for bed coil. Tube application of AFBC boiler, the material pasty mass should be finger pressed into the studs of the tube with maximum force. Finish should be given by pressing the hand palm against material applied, using surgical type thin rubber hand gloves.

Mullite refractory castable general use of mullite aggregate to as raw materials and configuration of a kind of low temperature in the insulation refractories, it is commonly used in the petrochemical industry tube furnace, light diesel oil, ethane cracking furnace lining, atmospheric and vacuum furnace and sulfur recovery device and steam boiler, tortoiseshell net heat insulation layer, two barrel and pipe insulation monolayer, and other industrial furnace door, see the fire hole, observation hole door lining, etc. The advantage of mullite refractory castable is that its refractory temperature is higher than other thermal insulation castable, which can be directly in contact with the flame and used as the lining of the kiln. Another kind of refractory castable is corundum mullite castable, which is a refractory castable prepared with corundum as aggregate and powder plus some binder.It has higher mechanical strength and abrasion resistance than high alumina refractory and Mullite refractory, but less thermal shock resistance.
Steel fiber castable is widely used in high temperature vulnerable parts of metallurgy, building materials and circulating fluidized bed boilers.As follows: according to the classification of the material, it is suitable for planning the corundum quality before and after the steel fiber reinforced castable first used in large cement kiln kiln and other industrial kiln lining, high aluminum and corundum mullite stone steel fiber reinforced refractory castable first used in the cement kiln kiln mouth, wicket cover, before and after cooling machine in high temperature resistant parts and other industrial kiln liner.
Non-stick aluminum refractory castable or non-stick castable, the non-stick aluminum castable combines with the feature of inorganic binder, add a certain amount of insoluble in aluminium new composite refractory material, control the liquid aluminum erosion of refractory, non-stick aluminum castable with high volume density, high strength, not for the nature of the aluminum liquid wetting, can significantly reduce the corundum phase anomaly grew up and molten metal and permeability of materials.Suitable for the bottom of aluminum melting furnace, wall of furnace, slag-scraping slope, chute, aluminum water bag and degassing box, etc.
High alumina castable is a refractory castable made of high alumina raw material with binder and aggregate in traditional ratio.On the basis of the preparation of high strength and high aluminum castable, the granule gradation is adjusted, different admixtures are added, cement dosage is reduced, performance is improved, medium temperature strength and softening temperature under load are increased, thermal conductivity is reduced, and thermal stability is good.The furnace body structure integrity is strong, the air tightness is better than the brick furnace, extends the furnace life, saves the furnace repair cost, the economic benefit is remarkable as the high aluminum refractory castable characteristic.
