Casting Sand made of olivine, with its sintering point at 1450 �ºC and melting point above 1760 �ºC, provides excellent
performance in iron castings (grey cast iron, nodular cast iron, tempered cast iron) and also performs well in non-
ferrous castings. Using olivine as casting sand, it contributes significantly to casting companies both financially and in
terms of quality. Especially in Mn castings, olivine is the definitive solution in these castings where surface roughness
is important. In addition, molds made of Olivine are preferred in problematic situations between the metal materials
poured during casting and the mold. Silica-containing sands react with the metal during casting, while the olivine
mold does not allow the metal to enter into its body. As Olivine's high magnesium content olivine sand, when used
with clays, increases its binding properties and significantly reduces the need for bentonite. Olivine's basic nature
makes it an ideal choice for manganese steel production. In contrast to silica sand, olivine sand does not interact
with manganese steels, keeping surface grinding costs to a minimum and giving high cleanliness casting results. Fine
grain olivine sand is also commonly used in brass, bronze and aluminum castings. This is relatively due to the
moisture-free properties of the material and the angularity of the particles. This property provides consistency and
low permeability, resulting in castings with very good surface treatment. The angular particles of olivine sand, even
when thoroughly crushed, ensure that it is still gas permeable after forging, which plays a very important role in the
escape of steam in castings. Olivine has a much higher return rate than silica sand. This is due to less upheaval and
less distortion in thermal shocks.
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.
