Chengde Beiyan New Materials Technology Co., Ltd.–Casting[core]Sand Quality Expert

(Reprinted from: Metal Gang)

　　Chengde Beiyan New Materials Technology Co., Ltd.Founded inIn 1998,It is a high-tech enterprise that relies on the advantages of yard silica sand resources, integrating the research and development, production and sales of casting sand and fracturing quartz sand series products, supplemented by related casting materials.

The company has built production bases in Chengde, Hebei, Luoyang, Henan, Nanyang, Liaoning, Zhangwu, Shaanxi, Baoji, etc., and has formed a cast sand recycling industry chain that integrates the research on silica sand material technology, the deep processing of silica sand for casting to the recycling and recycling of casting waste sand.

　　Casting laminated sand series

　　This series of coated sand is heated through the thermal coating process, that is, the original sand is preheated to a certain temperature, and the resin is added to melt, so that the resin is coated on the surface of the sand particles, and is cooled and broken. Screening to obtain coated sand. The process is computer-controlled throughout the process, avoiding interference from human factors, so the product quality is more stable and the quality is higher.

　　Features:

　　1.Suitable strength, can be used for differentcasting(Cast iron, cast steel, non-ferrous metals, 3D printing)Suitable special coated sand is developed for the production of various complex casting cores.

　　2.High strength, low air generation, low expansion, and high temperature resistance can effectively solve casting defects such as casting sticking, pores, veins, deformation, sintering, etc., and reduce the casting waste rate.

　　3. Good fluidity, good surface quality of the sand core produced, and high surface finish of the casting

　　4. Good scattering properties, easy to clean castings

5. The shell type has good thermal conductivity, fast curing speed, no layering, and no shell removal.

　　Roasted sand series for casting

　　This product is based on scrubbing sandSand treated with high temperature phase change of 900℃. The reduction in amount is low, the surface is cleaner, and the phase change and expansion of the silicon sand is maximized, reducing various casting defects caused by the expansion of the castings due to the expansion of the silicon sand.

　　Features:Low reduction in burning amount (≤.01%) The surface is cleaner and the high temperature expansion rate is low (900℃ thermal expansion rate ≤1.6%)Anti-sticking sand significantly reduces the amount of resin added.

　　Disappeared sand series for casting

　　Disappearing molded sand 20-40 mesh

　　Disappeared molded sand is a kind of sand that has been treated with scrubbing, shaping, and special processes, with a round grain shape (Angle coefficient≤1.15), high concentration, high firmness, good fluidity, good breathability and good reusability, is a special silica sand product for the disappearing mold casting process.

　　Features:Good roundnessHigh concentrationHigh firmnessGood liquidityGood reusability.

　　Scrubbing sand series for casting

This product is a kind of sand that has been scrubbed, desilted and highly surface-treated. It has round grains, clean surface, no cracks, low micro powder content, low mud content and low moisture content. The maximum bonding strength can be obtained with very little adhesive.

　　Features:Low mud contentLow moisture contentLow acid consumption valueLow content of micro powderHigh roundnessGood liquiditySmall amount of resin added

　　Resin coated quartz sand

　　This product uses high-quality natural quartz sand and polymer materials as raw materials, and can replace ceramic particles as fracturing proppants under certain conditions. The coated proppant will not react with the groundwater of shale gas or tight oil and gas reservoirs, and can extend the fracturing life and improve yield. It is a high economic value proppant.

Product features: It has excellent compressive resistance, low crushing rate, and strong flow diversion ability.

　　The company has obtained“National-level specialized, specialized, specialized, and new small giant enterprise”, “China's silicon sand production base for casting”, “China's casting materials industry's leading sand industry”, “Hebei Province's quality and efficiency enterprise”, “Hebei Province's specialized, specialized, specialized, specialized, and new demonstration enterprise”, “Hebei Province's excellent enterprise in casting industry”, “Hebei Province's good standardization behavior AAA-level enterprise”, “Hebei Province's high-growth leading enterprise”, “Hebei City's quality benchmark enterprise”, etc.
