Product Description Product DescriptionCoated sand. The surface of the sand particles is covered with a layer of solid resin film molding sand or core sand before molding. There are two coating processes: cold method and hot method: the cold method uses ethanol to dissolve the resin, and urotropine is added during the sand mixing process to coat the two on the surface of the sand grains, and the ethanol volatilizes to obtain the coated sand; The method preheats the sand to a certain temperature, adds resin to melt, stirs to coat the surface of the sand particles, adds urotropine water solution and lubricant, cools, breaks, and sieving to obtain coated sand. Used for steel castings and iron castings.Coated sand is a kind of resin coated sand with high quality and selected natural sand as sand base, through special performance resin coating system and ideal process technology. According to the technical requirements of different users, it strives to perfect the combination of room temperature performance, high temperature performance, collapsibility, fluidity, casting surface roughness and so on. It is widely used in automobile engines, diesel engines, hydraulic parts, steel castings, iron castings, etc Copper casting and aluminum casting and other industries.Product name: Coated sandMain raw materials: Natural quartz sandFeatures: High strength, high temperature resistance and low expansionSpecifications: 20-40mesh 40-70mesh 50-100mesh 70-140mesh 140-200meshScope of applications: Steel casting, iron casting, copper casting and aluminum casting, etcPrroduct Specification Slag Remover For Foundry NameChemical Composition(%)SiO265~80%Moisture≤0.5Al2O310~18%SolubilitySoluble in high concentration of hot alkaliCaO2.0~5.0.%PHneutralFe2O31.5~2.5%Packing density800~1200Kg/M3K2O1.5~4.0%Weightlessness3.0±2MgO1.0~2.0%Softening point1100oC~1300oCNa2O2.0~4.0%Melting point1200oC~1550oCTiO20.01~0.03%Proportion1.0~2.5g/ml Applications 1. Ordinary coated sand is composed of quartz sand, novolak resin, urotropine and calcium stearate, without any additives. Suitable for the production of general iron castings.2. High-strength, low-gas-generating coated sand is an updated product of ordinary coated sand. It is formulated by adding relevant additives and using new technology. Its strength is more than 30 higher than ordinary coated sand, and the amount of gas generated is also significantly reduced. Suitable for the production of complex precision iron castings.3. High-temperature coated sand has the characteristics of high strength and long heat resistance under high temperature, and is suitable for the production of complex thin-walled iron castings such as automobile engine cylinder blocks, cylinder heads, and container corners. 4. Easily collapsible coated sand has good strength and excellent low temperature collapsibility performance, suitable for the production of non-ferrous metal castings. 5. Other special requirements coated sand: Centrifugal casting coated sand, chilled coated sand, wet coated sand, anti-sticky sand, anti-veining, anti-orange peel coated sand, etc. Cast Steel Cast aluminumThe coated sand can be divided into cast iron, gray iron, cast copper, aluminum and steel according to the casting metal material. Cast Iron Cast Copper Why choose us Complete range We are specialized in producing all kinds of coated sand for casting, including cast steel, cast iron, cast copper, cast stainless steel, cast aluminum etc. Sophisticated technology It has advanced full-automatic coated sand production line, all kinds of testing equipment are complete. Worry free after saleProfessional after-sales service worry free shopping Product Advantage 1. Vibration cleaning sand, high strength, low gas, low expansion;2. Good dispersion and high surface finish of castings;3. The shell type has no layer, good thermal stability, good thermal conductivity, good fluidity, and the surface of the casting is flat;4. High strength, high temperature resistance, low expansion, good mold release, good sand resistance;5. The shell layer is uniform and does not peel off, and the curing speed is fast;Slag remover is a material used to remove impurities in molten iron or molten steel from ladle in steelmaking or casting industry. Its main components are SiO2, Al2O3 and some other chemicals. The general deslagging agent also has the function of heat preservation by covering the metal liquid.
