    摘要： Purposes of the present invention are to provide a dry coated sand having a high degree of fluidity at the room temperature, a method of advantageously producing the coated sand, and a method of producing a casting mold having excellent properties, by using the coated sand. The dry coated sand is obtained by mixing an aqueous solution of a water glass used as a binder, with a heated refractory aggregate, whereby water in the aqueous solution is evaporated, and a coating layer of the binder is formed on surfaces of the refractory aggregate. A moisture percentage in the thus obtained dry coated sand is controlled so as to be not more than 0.5% by mass. The intended casting mold is obtained by filling a molding cavity of a forming mold, with the dry coated sand, and passing a steam through the coated sand, to solidify or cure the coated sand.

    摘要： A method and a device for rapidly drying ware shell and a ware shell are provide, and it pertains to the field of precision casting technology. It is designed to solve the problem that the ware shell drying process fails to ensure high quality of a ware shell and rapid drying simultaneously when the ware shell has a complex structure. The method includes following steps: a. putting a ware shell to be dried in a sealed chamber; b. vacuuming the sealed chamber under the premise condition of controlling the ware shell in a constant temperature state, and cooling the gas in the sealed chamber in a predetermined time period to condensate the moisture in the sealed chamber; c. vacuum injecting gas to the sealed vacuum chamber to make the chamber return to normal atmosphere pressure; D. determining whether the ware shell is dry. If result is YES, then end, otherwise back to step b.
