用碳素铸钢(如ZG35)制造腭式破碎机的箱架和动腭等构件,对于只有铸铁件生产能力的中小工厂来说,具有困难。本文介绍用我们铸态混合基体球墨铸铁代替铸钢在生产腭式破碎机构件方面所做的工作。 所研制的铸态铁素体珠光体混合基体球墨铸铁,既有高于ZG35碳素钢的强度,又有接近于碳素钢的延伸率,其性能达到和超过 It is difficult for small and medium sized factories that only have the capacity of producing cast iron parts to manufacture pavilions, such as box racks and moving paws, of carbon steel castings (such as ZG35). This article describes the work done with our cast-in-place ductile cast iron instead of steel for the production of palate crusher components. The developed as-cast ferrite pearlite matrix ductile iron, both higher than the strength of ZG35 carbon steel, but also close to the elongation of carbon steel, its performance to meet and exceed
