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.

Like wax candles, Rouseki (Pyrophyllite) is white and semi-transparent, and has a waxy texture when touched. It is very brittle, and tends to crack largely along the stone joints. Up close, this stone looks grayish white, but may look blue from a distance. The ore looks so similar to pottery stone ore that they cannot be distinguished. But there is a difference in their texture, color, and how they crack, and with experience, their differences become more visible. They not only look and feel different, but their applications and properties also differ significantly. It's used as Firebricks, crucibles, glazes, fire-resistant powders, etc.

We offer high quality Gray sandstone blocks and slabs which are useful in multiple building and construction structures. The product is available in the form of tiles, slabs, bocks in natural sawn as well as polished surface. The product is also known as Sagar Gray in the global market.

Quicklime (or calcium oxide or burnt lime) is obtained by calcining pure limestone at temperature above 9000C. This highly reactive product is essential to many industrial processes. Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term lime connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate. Application: Steel Making, FGD, Construction, Masonry & Mortars, Water Treatment, Chemical Processes, Mining Industry, sugar industry, Paper, Pulp and PCC, Remediation of Sludges and Wastes and Glass Manufacturing. Packing: 1000kg Jumbo bag. Item Specification CaO: 92.5% ± 2 Loss on Ignition at 1000 °C: 4% ±2 Grain Size: 10- 60 mm Reactivity: High
