Sponge Iron: Direct Reduced Iron, obtained by heating iron ore with coal & dolomite in rotary kilns used for steel making.

Iron ore in its solid condition is directly reduced to make sponge iron, a metallic product. The goal of manufacturing sponge iron is to take the oxygen out of iron ore. It is the first stage of making steel. Steel is mostly made using sponge iron in electric furnaces.

Quartz Sand or Quartz Powder is manufactured by crushing crystalline quartz lumps to various sizes and is also known as white silica sand. Quartz Sand has very high silica content as compared to river sand and has negligible or no natural impurities. Quartz Sand is highly resistant to both mechanical and chemical weathering and makes an excellent filter media. When quartz lumps are grounded to the size of 2-3 mm stones, they are colloquially known as silex.

Description: Live sand, a term used in aquarism, is natural reef coral sand populated with millions of beneficial bacteria and organisms which aid in the dissolving of organic wastes like ammonia, nitrites and nitrates produced by larger organisms in saltwater aquariums.It is sand of particles originating in tropical and sub-tropical marine environments from bioerosion of limestone skeletal material of marine organisms. One example of this process is that of parrot fishes which bite off pieces of coral, digest the living tissue, and excrete theinorganic component as silt and sand. However, the term "coral" in coral sand is used loosely in this sense to mean limestone of recent biological origin; corals are not the dominant contributors of sand particles to most such deposits. Rather, remnant skeletal fragments of foraminifera, calcareous algae, molluscs, and crustaceans can predominate. Because it is composed of limestone, coral sand is acid-soluble. Live Sand is most important for a strong biological system - Live Sand is used to provide a strong biological system to any saltwater aquarium. Full of beneficial bacteria that break down nitrogen-based waste that is produced by marine life. This waste if not elliminated is what would cause severe harmful chemistry spikes in the aquarium water. Live Sand is equally as nescessary to fish only aquarium tanks that incorporate external filtration. Beneficial Sand Dwellers provide a natural food source - There are many beneficial types of worms and crustaceans found in the live sand. These dwellers are used by many fish as a natural food source. The grain size of ranges from fine (sugar size) to a medium grade. Live Sand acts as an immediate PH Buffering System to the saltwater aquarium.The natural components to live sand act as a buffering agent to the saltwater aquarium system. By keeping PH from fluctuating, it provides a natural means of keeping the stress levels of your marine fish to a very low level. What IS the correct amount of Live Sand to add to an aquarium? The recommended amount is 1 to 1-1/2 pounds per gallon, for a sand layer of up to 2 inches. If you wish to have a 4 inch layer, which is widely used, provide 2 to 3 pounds per gallon. What additioinal critters should be purchased to go in Live Sand? We recommend incorporating sand-sifting invertebrates such as sand stars, horse shoe crabs or sea cucumbers and serpant stars and/or brittle stars along with your fish to aquariums that contain live sand. These animals will maintain the proper oxygen content in the top layer of the sand, and stir up detritus so that it can be removed from the aquarium by the mechanical filter. When do I add the Live Sand to my aquarium system? Live Sand needs to be added right from the begining, as it is beneficial in the entire cycling process of the new aquarium

We offer china clay, one of the purest of the clays, is a hydrated aluminum silicate. It is composed chiefly of the mineral kaolinite usually formed when granite is changed by hydrothermal metamorphism available in lumps & powder form, in off – white / snow – white / super snow – white color and in a fineness of up to 700 mesh ( max 0.5 % retention on sieve ) used in paints, foundry, detergent cake.

Sponge iron is a metallic product produced through direct reduction of iron ore in the solid state. It is a substitute for scrap and is mainly used in making steel through the secondary route. Sponge iron is an iron source relatively uniform in composition, and virtually free from tramp elements. It is used increasingly in Electric Arc and Induction furnaces to dilute the contaminants present in the scrap used in these processes. It has an associated energy value in the form of combined carbon, which has a tendency to increase furnace efficiency. For captive DRI production facilities, there is an added advantage that the delivery of hot DRI to the furnace can reduce energy consumption to 16 - 20%. With India being the largest producer of Sponge Iron, Saraf Trexim Limited aims to supply the best quality of Sponge Iron to our various renowned buyers.

Sponge Iron is produced through direct reduction of iron ore in the Solid State. It is mainly used in making steel through the induction furnace route. The process of sponge Iron making aims to remove the oxygen from Iron ore.

We work in close coordination with the team members and packaging professionals; they ensure that the products are packed sternly using the finest quality packaging materials. In order to ensure complete satisfaction of the customers, we deliver the orders on the scheduled time. Preparation Procedure Quartz Grains & Powder (Quartz Grains, 0-5 MM*) is for high performance at high temperature during melting in coreless induction furnace, with an added advantage of reducing slag deposit. While preheating it to a temperature of 100-150o C for removal of moisture particles, it is imperative to ascertain that there are no impurities during this process. At the next step after procuring the material by our valued clients this requires to be mixed with Boric Acid once the mass is cooled below 40o C. The percentage of which varies from 0.8-1.4%, depending upon the operating temperature. Quartz is used in small capacity induction furnace, as its low resistance to high temperature thus minimizing the cost of production, while maintaining the productivity and quality of product. Moreover, Gajanan Group ensures that the composition of the Quartz Grains & Powder (Quartz Grains, 0-5 MM*) is optimized on the basis of the furnace capacity to achieve better bulk density. At Gajanan, the processing unit is completely automated, no man-power, so that question of an error is negated. The unit is further furnished with heavy-duty magnets of 12,000 gauss, so that the final product contains no free iron in it which gets generated during the process, as iron content causes immense damage to the furnace.
