The invention relates to a production process of an impact-resistant wear-resistant cast stone part. The cast stone part consists of a cast stone matrix, a high-temperature-resistant fiber reinforcement and a high-temperature-resistant fiber gridding cloth reinforcement. The process comprises the following steps: A, blending: uniformly mixing a cast stone powder raw material with high-temperature-resistant fibers, adding water, and performing stirring until the mixture is uniform; B, die filling: according to the thickness and the shape of the cast stone part, filling the stirred raw materialinto a graphite mold in an alternate manner of one layer of raw material and one layer of high-temperature-resistant fiber gridding cloth for molding; C, heating: putting the molded prefabricated partand the graphite mold into a heating furnace, and performing heating until the cast stone powder raw material is completely molten; D, crystallizing and annealing: crystallizing the cast stone part together with the graphite mold at 1000 DEG C, and then performing annealing and cooling to room temperature; and E, demoulding. The impact strength of the cast stone part prepared by the process is 40times higher than that of a pure cast stone part, and the bending strength is 5-12 times higher than that of the pure cast stone part.
一种抗冲击耐磨铸石件生产工艺，由铸石基体,耐高温纤维增强体、耐高温纤维网格布增强体构成，包括以下步骤：A.配料：将铸石粉原料与耐高温纤维均匀混合，加水同时搅拌至均匀。B、装模：根据铸石件的厚度及形状，将搅拌好的原料按一层原料一层耐高温纤维网格布的方式装入石墨模具成型。C、加热：将成型的预制件连同石墨模具放入加热炉里进行加热至铸石粉原料彻底熔融。D、晶化和退火：将铸石件连同石墨模具在1000℃下进行晶化处理再退火冷却至室温。E、脱模。采用本发明的工艺制备的铸石件抗冲击强度比纯铸石件大40倍，抗弯强度大5至12倍。
