摘要
提出一种包内快速预测铁水石墨形态的新方法及新装置．新方法的核心是以气泡幅频参数所形成的当量张力来表征铁水石墨形态，故称幅频当量法．应用该方法可在１０ｓ 内完成全部测试过程．以气泡幅频当量法为基础而研制的微机化测试新装置主要由快换探头、微型气路系统、高精度单片机数据采集系统等组成，具有操作简便。
In the paper, a new method and a device for fast evaluating the graphite shape in liquid cast iron are advanced. The new method is named amplitude and frequency equivalent of bubbles and its foundation is to take the pressure in the bubble and the frequency of blowing bubbles as the characteristics to obtain the equivalent by which the graphite shape in liquid cast iron can be known before casting. The testing process will take only 10 seconds. The new device based on the new method consists of a heat resistant and replaceable detector and a microcomputer acquisition system. The new method and the device have advantages of convenient operation, high resolution ratio and high anti jamming ability.
