Counterweight iron sand.
The counterweight iron is a kind of iron ore raw materials in weight, its role is to balance. For example, the counterweight engineering machinery in sporting goods in weight.
For weight or pressure reuse of iron ore, iron ore, the proportion of general counterweight iron for 4.2 - 7.2 (bulk density of 2.5 - 4.8) between, customers are in terms of the drainage density (true specific gravity drainage density [1]). The product weight different needs of different proportion of the iron weight.
Counterweight iron sand density
The proportion of general counterweight iron for 4.2 - 7.2 (bulk density of 2.5 - 4.8) between, specifications: 0.2-2.0mm, customers often to drainage density (specific gravity), as the purchase of indicators. The product weight different needs of different proportion of the iron weight.
A small proportion of iron weight: 6.2-6.5 tons / m3 4.1-4.3 tons / m3 reactor
A large proportion of iron weight: 6.8-7.2 tons / m3 4.8-5.2 tons / m3 reactor

Iron sand is made from broken heat-treated iron shot. It is of high hardness with sharp angles, which make suitable for high-speed spray etching and scraping. It is especially useful in metal surface treatments, which have higher etching and scraping requirements. It is also used for surface treatment works of outdoor sandblasting operations.

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.
