Olivine is used as sandblasting material for blasting operations. As the hardness of the sand is 6, 5-7 (Mohs) and the characteristics such as its angular shape, make this material attractive in sandblasting market. As it doesn’t contain chloride, you will never experience corrosion and cohesion problems. As the iron in its content is Fe2O4 it never gets into chemical reaction with the oxygen in air and water. That’s why there will not be any oxidation which will allow for more long-lived paintings. As it doesn’t contain any free silica, it is never a cause for silicosis disease. The usage of materials containing free silica such as quartz sand is prohibited in many countries (Turkey, England, Netherland, Sweden, and Norway)

Olivine is also widely used as backing material between wall and coating layers of tundishes. Olivine protects the walls of tundishes on account of its high melting point (1760-1800 Cº). In between the Chalmette bricks and magnetite plates olivine serves your Tundishtappings in a perfect way and provides 12-14 tapping’s (application life of magnetite). Olivine helps you to protect the outer liner of tundishes and decreases the maintenance and repair expenses to the minimum. Also, Olivine helps the users to save from time and labour by the help of its water holding level under %2 present

Olivine, with over %98 free opening success rate, high magnesium and low LOI value we offer you one less thing to worry about EAF tapping’s. Any kind of size choice and grain size distribution is available in order to supply the best possible service. Having a free opening success rate above %98. With the high MgO content, the product is durable to the  1760 Cº (3200 Fº) With the production techniques special to us, grain shape is not angular but round which provides Olivine EBT sand the fluidity and help the sinter free, tap hole openings. High quality olivine sand helps the user saving from time and labour. Every single sizing for EBT applications, percentages of distribution is engineered in accordance with long years of experimental acquisitions. There happens no gap between the grains in order to avoid any kind of molten steel leakage from the tap hole which is also a cause of the sintering of the grains and decreases the free opening rates. Olivine EBT sand the routine quality controls start from the mine deposit which prevents the unqualified material delivered to the plant. Also, the chemical controls of the products areconstantly made during the production and at the ports.

Olivine casting sand with its sintering point 1450 Co (2642 Fo) and melting point over 1760 Co (3200 Fo) performs excellent for the ferrous castings (grey cast iron, nodular cast iron, malleable cast iron) and performs very well for thenonferrous castings. Especially for the Manganese (MN) castings where the surface smoothness is important Olivine is the absolute solution. Because of its alkaline characteristic, it performs excellent, especially for manganese castings. As olivine doesn’t react with steel, provides smoother surfaces. The re-usage rate is higher than silica sand. Environment-friendly. Because of its silica content is combined, it doesn’t cause silicosis. Resistant to thermal shocks. Low thermal expansion. More economical in compassion to Zircon and Chromite Sand.
