Small batch, high qualitythe best choice for solution treatment of aluminum!! Three performance guarantee parameters:  Furnace temperature uniformity: ±3 Temperature control precision: ±1  Workpiece transfer time: 6-15s  Equipment Features A patented self-locking mechanism is adopted for the furnace door, ensuring that the furnace door will not descend by itself under any circumstances.  There is a flexible sealing connection between the furnace door and the furnace body; the furnace door is pneumatically compacted, ensuring the synchronous sealing performance of the whole sealing surface.  Each mechanical action is equipped with a perfect self-locking function, ensuring operation reliability and safety. Especially, there is a well-designed logical relation and reliable hardware-software logic interlocking circuit among the heating system, fan operation system, furnace door switch system, charging basket lifting system, water tank movement system and mixing system. They can keep the equipment and thermal treatment device safe in case a sequence error is caused by manual operation or a failure occurs in an action process during automatic operations.  High furnace temperature uniformity. A large-flow and high-air-pressure heat-resisting fan is adopted, able to generate enough recirculating air quantity and pressure; the super-large furnace consists of multiple temperature control zones including one main zone, ensuring that temperature rises synchronously in all of the temperature control zones; the all-fiber furnace lining minimizes heat loss, ensuring that the furnace chamber temperature gradient is within a certain range. High furnace temperature control accuracy. Multiplex control maximally ensures that the furnace chamber does not overheat, thus protecting workpieces from being softened and over-burnt.

Guar gum is a fiber from the seed of the guar plant. Guar gum is used as a laxative. It is also used for treating diarrhea, irritable bowel syndrome (IBS), obesity, and diabetes; for reducing cholesterol; and for preventing “hardening of the arteries” (atherosclerosis). In foods and beverages, guar gum is used as a thickening, stabilizing, suspending, and binding agent. In manufacturing, guar gum is used as a binding agent in tablets, and as a thickening agent in lotions and creams. How does it work? Guar gum is a fiber that normalizes the moisture content of the stool, absorbing excess liquid in diarrhea, and softening the stool in constipation. It also might help decrease the amount of cholesterol and glucose that is absorbed in the stomach and intestines. There is some interest in using guar gum for weight loss because it expands in the intestine, causing a sense of fullness. This may decrease appetite. USES: Diarrhea. Adding guar gum to the tube feeding formula given to critical care patients may shorten episodes of diarrhea from about 30 days to about 8 days. High cholesterol. Taking guar gum seems to lower cholesterol levels in people with high cholesterol. Guar gum and pectin, taken with small amounts of insoluble fiber, also lower total and “bad” low-density lipoprotein (LDL) cholesterol, but don't affect “good” high-density lipoprotein (HDL) cholesterol or other blood fats called triglycerides. Diabetes. Taking guar gum with meals seems to lower blood sugar after meals in people with diabetes. By slowing stomach emptying, guar gum may also lessen after-meal drops in blood pressure that occur frequently in people with diabetes. Constipation. Irritable bowel syndrome (IBS).

Fly Ash: Fly Ash is by product generated during combustion of coal, and comprises the fine particles that rise with the flue gases. Ash which is collected from the bottom is termed bottom ash. Fly ash is collected by electrostatic precipitators or other particle filtration equipment before the flue gases reach the chimneys of coal-fired power plants and together with bottom ash removed from the bottom of the furnace is in this case jointly known as coal ash. Depending upon the type of coal being used, the specification of Fly Ash varies considerably, but Fly Ash contains substantial amounts of silicon dioxide and calcium oxide (CaO), both being endemic ingredients in many coal-bearing rock strata. We are a reputed Fly Ash Exporter based in India and are supplying Fly Ash different cement, ready mix concrete, steel, refractories and construction industries. The Major Utilization Areas Of Fly Ash : - Manufacture of Portland Pozzolanic Cement & Performance improver in Ordinary Portland cement (OPC). - Part replacement of OPC in cement concrete. - High volume Fly Ash concrete. - Roller Compacted Concrete used for dam & pavement construction. - Manufacture of ash bricks and other building products. - Construction of road embankments, structural fills, low lying area development. - As a soil amender in agriculture and wasteland development. Types of Fly Ash: - According to the type of coal used fly is classified into two types. Anthracite and bituminous coal produces Fly Ash classified as class F. Class C Fly Ash is produced by burning lignite or sub-bituminous coal. Class C Fly Ash has self-cementing properties. - Class F and Class C Fly Ash are products of the combustion of coal in large power plants. Fly Ash is collected in electrostatic precipitators or baghouses, and then transferred to large silos for shipment. When needed, Fly Ash is classified by precise particle size requirements, thus assuring a uniform, quality product. - Class F Fly Ash is available in the largest quantities. Class F is generally low in lime, usually under 15 percent, and contains a greater combination of silica, alumina and iron (greater than 70 percent) than Class C Fly Ash. - Class C Fly Ash normally comes from coals which may produce an ash with higher lime content generally more than 15 percent often as high as 30 percent. Elevated CaO may give Class C unique self-hardening characteristics. Minimum Order Quantity : 1 container

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.
