炉内低压载气脱蜡的收蜡系统

在硬质合金真空烧结过程中，必须建立一套完整的收蜡系统，以防止石蜡对真空系统的损害．本文对石蜡在低压载气脱蜡过程中的行为，收蜡装置应该满足的基本要求，和实现良好收蜡的可能方法进行了较详细的讨论．

THE PARAFFIN COLLECTING SYSTEM FOR THE SWEEP SELUBING UNDER ATMOSPHERE IN VACUUM FURNACE

The sweep delubing vnder atmosphrer in Vacuum furnace is a important way during carbide is sintered in uacuum furmace. For getting the full advantage of the sweep delubing under atmosphere,there, there must be a set of the best paraffin collecting system to prevent the contamination of vacuum system from paraffin. In this paper,we have detailed tbe feature ofparaffin in the sweep delubing under atmosphere,and condition of the paraffin collecting systen which must be satisfied,andthe more idear way for constructing the paraffine collecting system. This paper may be referenced for designer and operator.
