* 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.

Magnesia Bricks Description Magnesia Bricks are alkaline refractory materials. These products have over 90% magnesium oxide content and adopt periclase as the principal crystalline phase. Magnesia Bricks can be divided into two categories of Burnt Magnesia Bricks and Chemical Bonded Magnesite Brick. They have excellent performance of superior high temperature mechanical strength and volume stability. Magnesia Bricks can service in the high temperature of 1750.. They are ideal products for glass furnace application. Magnesia Bricks Features: It is a kind of alkaline refractory product with periclase as main phase magnesite-alumina spinel clinker as basic material. the product has such characteristics as good temperature vibration, good strength and volume stability in high temperature. Magnesia Bricks Application Basic open-hearth furnace for steelmaking Electric furnace bottom and wall Permanent lining of oxygen converter Non-ferrous metal metallurgy furnace Hyperthermia tunnel kiln Lining of rotary cement kiln Heating furnace bottom and wall Regenerative chamber of glass furnace Magnesia Bricks Properties High Refractoriness Good alkaline slag erosion resistance High apparent initial softening temperature Good thermal conductivity High thermal expansion Magnesia Bricks Manufacturing Process Burnt Magnesia Bricks are manufactured with magnesite clinker as the raw material and fired in the high temperature of 1550~1600 after smashing, burdening, mulling and molding. High-purity products can be fired in the temperature that over 1750. Chemical bonded magnesite brick is produced with certain chemical bonding through mixing, molding and drying.

Ramming mass is commonly used in metallurgy, building materials, non-ferrous metal smelting, chemical, machinery and other manufacturing industries. Ramming mass is widely used in non-core intermediate frequency furnace and core induction furnace. As an intermediate frequency furnace ramming material, refractory ramming is applied to melt gray cast iron, nodular cast iron, malleable cast iron, vermicular cast iron, and cast alloy steel; to melt carbon steel, alloy steel, high manganese steel, tool steel, heat resistant steel, stainless steel, molten aluminum and its alloys; to melt red copper, brass, white brass, bronze and its alloys, etc. Induction furnaces are used for melting cast iron, mild steel and various alloy steels in foundries and making of steel in mini steel plants using sponge iron The refined high silicon, low iron quartz sand and quartz powder are selected and the fused quartz sand is added as the refractory material., with no slag, no crack, damp proof, convenience of repair, and the corrosion resistance, thus greatly improving the furnace service life span and the economic benefit.. Silica ramming mass can safely be used up to an operating temperature of 1600 deg C. Since it expands very little, it is superior to both alumina and magnesia refractories to resist thermal shocks Acid ramming material is the premixed ramming mass of the lining material. The acid ramming mass is used to smelt a series of metal materials such as ordinary steel and carbon steel. The lining practice best suited to a particular furnace depends upon the capacity and design of the furnace, operation practice adopted during making of a heat, and furnace output.
