摘要： A casting mold which is molded by heating mulled sand including a mixture of refractory molding sand particles, an inorganic water soluble binder and water, wherein the inorganic water soluble binder is made of a combination of a sulfate compound such as magnesium sulfate heptahydrate and a borate compound such as sodium tetraborate decahydrate. The casting mold is formed by baking the mulled sand in such a manner that at least part of the sulfate compound retains water of crystallization therein and the borate compound is once fused and then cured.
摘要翻译： 一种铸造模具，其通过加热包括耐火型砂粒，无机水溶性粘合剂和水的混合物的砂光而成型，其中无机水溶性粘合剂由硫酸盐化合物如七水合硫酸镁和硼酸盐的组合 化合物如十水合四硼酸钠。 通过以至少部分硫酸盐化合物保留结晶水并使硼酸盐化合物一旦熔化然后固化的方式，将所研磨的砂子烘烤形成铸模。
