本文介绍了梅河口车辆段提高轴瓦白合金粘结质量采取的两条措施:一条是控制浇注炉、预热炉、胎膜、瓦体及挂瓦室室内温度;另一条是采用观察轴瓦内弧面白合金镀层面积的方法来控制轴瓦白合金粘结质量。并介绍了提高轴瓦内弧面白合金镀层面积的具体措施和判断助焊剂成分之一——氯化锌质量好坏的方法。
This paper introduces two measures taken to improve the bonding quality of the aluminum alloy pad at Meihekou Depot: one is to control the indoor temperature of the pouring furnace, preheating furnace, fetal membranes, tile body and hanging wall; the other is to observe the inner arc of the bearing bush Surface white alloy coating area method to control the bearing tile white metal bonding quality. And introduced the specific measures to improve the surface area of the arc shell white alloy coating and determine the method of one of the flux components - zinc chloride quality is good or bad.
