Properties of Kalin Ceremic Sand (Compared with other special Sand)
Origin of kailin ceramic sand
About the origin and the marketing of kailin ceramic sand,Mr. Liu Mandui,the general manager, once told a story as follows.
"Early in 1997, I engaged in the production and research work of resin coated sand. One day, a few friends and I walked into a ceramic sand production plant which product electricity-melting bauxite sand, and found a special artificial sand. It has very good round appearance and smooth surface. Oh my God! Isn't that the optimal sand which foundry men looked for? When we left the plant, I caught some sand sample for further testing.
"Two years later, in August 1999, we found a company, Luoyang Kalin Foundry Material Ltd., to manufacture and market those molten bauxite sand---kailin ceramic sand. At that time we made ceramic sand by calcining the bauxite ore. Soon we found that this kind of sand were not suitable for foundry use due to it's lower refractoriness. Not long after that, we started to use melting and blowing process to produce ceramic sand.
"So, here comes a question. What's the primary difference between the oil field using ceramic sand and the foundry using sand ? In my opinion, for oilfield ceramic sand, we mainly concern it's crush strength, but for foundry use ceramic sand, refractoriness maybe is the first consideration. For it's good Eucharistic for molding and core making, it's a real treasure in foundry, we called it "ceramic sand"in Chinese. Soon, there appeared the word "ceramic sand"in china foundry trade circle .
"In 2000, Luoyang Kalin Foundry Material Ltd. Issued it's first ceramic sand ad as "ceramic sand " on the famous monthly named "foundry"sponsored by the CFA. From then, we have kept this ad on it for about 15 years. At the same time, we have marketed the ceramic sand from north to south, from china to abroad. and in 2005 we registered a trade mark as "ceramic sand"in China and declared a patent (patent number: 20,051,001,799.6)
"Along with the marketing and application of the ceramic sand, more and more foundries have taken the advantages of lower casting costs, less foundry waste emission and higher casting quality contributed by using kailin ceramic sand. Today, the kailin ceramic sand, for its superior performance, expand its application quickly, such as use in resin bonded sand, sodium-silicate sand, green sand, lost foam, vacuum molding process, etc.. We would like it to contribute to the progress of foundry forever."
Advantage of ceramic foundry sand:
1, Perfectly round shape with higher fluidity improves fill-in efficiency while reducing the resin leve
2, Smooth surface of spherical shape greatly improves collapsibility after pouring
3, Very low thermal expansion ensures fewer or no casting defects such as veining and deformation
4, Excellent thermal conductivity and heat absorption capacity close to that of Zircon
5, Superior refractory equivalent to Zircon and Chromites
Packing: 1 MT big bag or 25kg paper bag *40 bags on one pallet ;As per customer's requirement
Remark: specification and size can be optimized by per customer' requirement
Application of Ceramic Sand
1.Widely used in foundry technique like resin-bonded sand, sodium silicate sand, and clay- bonded sand for sand core and casting mould making.
2.Replace chromite sand and widely used in sand core making like jacket core, oil duct core, tappet core of engine.
3.Replace chromite sand for steel casting facing sand and sub-layer of molding sand (backing sand). 4.Widely used as dry sand and sand box for EPC process and V method of casting processes. 5.Widely used as the main raw materials of advanced refractory products (Ladle drainage sand,gravity casting material, casting coating, etc.).
6.Widely used as cleaning sand for copper and aluminum alloy castings.
