摘要
油石是一种磨具,主要用于加工机械零部件,被誉为“工业的牙齿”,用量很大。普通的油石主要是由刚玉(Al2O3)做成的,硬度不够高,消耗太快,而β-SiC作为一种新材料,其做成的油石硬度较高,经久耐用,有望成为传统刚玉油石的替代品,因此本文主要研究β-SiC油石的制备及其性能。
本文从配方和工艺两个方面对β-SiC油石的物理性能进行了详细的研究,得出了在实验条件下的最佳配方和工艺。即:
最佳配方:当β-,,,,,,。
最佳工艺:陈腐时间为1d,成型压力为30MPa,烧结温度为900℃,竖放。

ABSTRACT
Oilstone is an abrasive tool, which is mainly used for processing the mechanical parts and pared to the “industrial tooth”. There is a great amount of its products in industry. The ordinary oilstone is mainly made of corundum (Al2O3) with lower hardness and easier to run out. However,β-SiC, as a new material, that can be used into the oilstone with higher hardness and better durability, is expected to e a substitute for the traditional corundum oilstone. As a result,this paper have been studied the preparation and properties of β-SiC oilstone .
In this paper, physical properties of β-SiC oilstone have been studied in detail from two aspects of formulation and process, and obtained the best formula and process under the experimental conditions. Namely:
The best formula: When the content of β-SiC is g, potassium feldspar is g, fine naphthalene for g, dextrin as g and g sugar water, B4C for g, kaolin as g.
The optimum process: Stale time is for 1 d, molding pressure for 30 MPa, sintering temperature of 900 ℃, and vertical put.
