以难熔耐火材料为主要材料,以可溶性盐作粘结剂的制芯混合料,是国外近年来发展很快的新型混合料,可用于铝、镁、铜、铸铁、铸钢、不锈钢和钛合金的铸造。 可溶芯比一般砂芯强度高,耐热性、导热性好,不发气,可降低铸件的夹砂、气孔等缺陷。对铸铝合金还有激冷效果,铸件冶金质量好,无疏松、针孔。型芯容易清除,无粉尘、噪音,不污染环境。清理时不 Refractory materials as the main refractory materials, soluble salt as a binder system of the core mixture, is the rapid development in recent years abroad, a new type of mixture can be used for aluminum, magnesium, copper, cast iron, cast steel, stainless steel and titanium Alloy casting. Soluble core than the average sand core strength, heat resistance, thermal conductivity, no gas, can reduce the sand casting, porosity and other defects. There are chilling effect on the cast aluminum alloy, casting metallurgy, good quality, no loose, pinhole. Core easy to remove, no dust, noise, do not pollute the environment. Not clean up
