辅料称重和将其加入型砂中的方式,对湿型砂的性能影响至关重要。一般情况,各种辅料是分别称重,然后按先后顺序加入混砂机中的。现在有一种新的辅料添加装备,它不使用体积定量法,而可准确地称量四种辅料,并预混合后再一起加入混砂机中,利用该装置添加辅料的工艺流程如图1所示。 The way the excipients are weighed and added to the sand is crucial to the performance of the wet sand. Under normal circumstances, all kinds of excipients were weighed separately, and then added to the sand mixer in the order of priority. There is now a new excipient adding equipment, which does not use the volumetric method, but accurately weighed four excipients, and then mixed with pre-mixed sand mixer, using the device to add excipients process shown in Figure 1 Show.
