摘要
本文进行了年产200吨YG类硬质合金烧结车间的设计,介绍了WC-Co硬质合金的力学性能、应用、发展前景和常规制备方法等。根据设计任务书的要求和相关粉末冶金车间设计规则制定了WC-Co硬质合金的工艺流程。另外,主要针对球磨、压制和烧结三大工序进行了物料衡算,查阅资料对当前国内的相关设备进行了搜集整理,根据物料衡算和设备参数对球磨机、成型压力机、真空烧结炉等基本设备进行了选型和台数的合理选取,并进行了工作制度的合理性制定、设备的合理化布置及车间平面和厂区平面的布置。最后,根据国家相关制图标准绘制了WC-Co硬质合金生产的工艺流程图、厂区平面布置图、烧结车间平面布置图和烧结车间的剖面图。

Abstract
The sintering workshop in where WC-Co hard alloys are produced for 200 tons per year has been designed in this mechanical properties of WC-Co hard alloy’s, its applications and prospects for development and the conventional preparation method were introduced. According to the design assignment and the correlative powder metallurgy workshop design practice, the WC-Co hard alloy technical process was developed. In addition, mainly for ball milling, pressing and sintering processes three primary working procedures were calculated material balance. Accessing to information on the current domestic related equipment were collected more, the ball mill, molding presses, vacuum sintering furnace and other basic equipment for the selection of a reasonable selection and number of units were carried out. The rationality of the working system formulated, equipments rationalization arrangement and workshop plane and factory plane layout were also carried out. Finally, the author has drawn the chart of the WC-Co hard alloy production flow, the floor-plans of the factory area and the sintering workshop, and the Sintering workshop sectional drawing according to the interrelated national charting standard.
Key words: WC-Co hard alloy; material balance; equipment selection; workshop design; Sintering
