Ceramic Foundry Sand Silica Replacement

With smooth surface and perfect shape ceramic sand has smallest superficial area making the volume added to adhesive and curing agent much less average 40 50 less.

Ceramic foundry sand silica replacement.

Green diamond foundry sand is available in ferrous and non ferrous foundry grade sands and is the ideal silica free replacement for olivine and silica sands for molding and coremaking. This ceramic sand is made from a bauxite based material which produces hard particles that last longer than other ceramic medias on the market. Supersand is a spherically shaped bauxite sand manufactured by melting bauxite in an electric arc furnace followed by a proprietary spraying process. Due to ceramic sand s unique physical and chemical properties it can be used in a wide variety of foundry processes.

Foundry sand is high quality silica sand with uniform physical characteristics. It is an artificial foundry sand that is regarded as the right substitute for chromite sand ziron sand and fused silica sand. It reduces the occurrence of casting defects such as veining penetration and burn on resulting in lower cleaning cost. The shape of ceramic foundry sand is spherical and the angle factor is less than or equal to 1 1.

Ceramic sand can serve as a replacement for silica sand and substitute for both chromite and zircon sands in many applications. It is produced from ferrous and nonferrous metal casting industries where sand has been used for centuries as a moulding material because of its thermal conductivity. Sphereox ceramic foundry sand versus silica sand has a lower thermal expansion resulting in higher precision and accuracy of castings while also leading to lower scrap cost and cost to correct inaccuracies. The company developed kailin ceramic foundry sand in 1999 and gained over 20 patents in foundry industry area.

Supersand is a ceramic sand. Replacing silica sand with carbo ceramic casting media is the most cost effective way for a foundry to meet osha requirements for silica dust exposure. Unlike silica sand carbo ceramic casting media produces no respirable silica dust so it easily complies with osha 1926 1153 silica dust permissible exposure limits pel. Ceramic ball bauxite china foundry sand perfect replacement for silica sand qingdao duoyuan new materials co ltd.

It is well regarded as a revolutionary new foundry sand. Indian foundries produce approximately 1 71 million tons of waste foundry sand each year metal. Us 480 00 520 00 metric ton. Supersand beaded foundry sand provides a unique combination of spherical shape grain chemistry and physical properties that result in.
