大型薄壁铸钢件的湿型铸造,在国内来说还是一项比较新的工艺方法.根据工厂生产实践,铸钢件采用湿型铸造,它的优越性很大,有推广和发展的前途. 我厂在铸钢件的湿型铸造工艺上,经历了由小到大、由少到多、由简单到复杂的发展过程,从简单的前后从板、闸瓦托、拱架柱逐渐发展到车辆上最大的配件——摇枕、整体构架上来应用. 铸钢件采用湿型铸造并不是在任何情况下,任何一种配件都可以采用,而是要根据铸件的技术条件、形状与工艺要求等来选择.现以整体构架这一大型薄壁铸钢件为例,介绍湿型铸造中的问题.
Large-scale thin-walled castings of wet-type casting, in the country is still a relatively new process method. According to factory production practices, castings using wet casting, it has great advantages, promotion and development of the future. Casting plant in wet casting process, has experienced from small to large, from as few as possible, from simple to complex development process, from simple before and after the plate, brake watts, arch column gradually developed into vehicles On the largest parts - bolster, the overall framework up applications. Casting steel with wet casting is not under any circumstances, any kind of accessories can be used, but according to the casting of the technical conditions, shape and process requirements To select the whole structure is now a large thin-walled castings, for example, describes the problems in wet casting.
