本发明公开一种电子束冷床熔炼炉铸锭质量控制装置和方法，该方法通过重力传感器对精炼冷床中溶体重量的变化进行实时监测，然后将监测数据实时发送到信号转换器，信号转换器根据当时熔炼金属液态时的密度和结晶器的尺寸将重量变化转化为拉锭速度发送至控制器，控制器向拉锭系统发送拉锭信号，从而达到拉锭速度与熔炼速度精确匹配、提升铸锭质量的目的。

 The invention discloses an electron beam cold bed smelting furnace ingot quality control device and method. According to the method, a gravity sensor monitors the weight change of a solution in a refining cold bed in real time, then monitoring data are sent to a signal converter in real time, the signal converter converts the weight change into the ingot pulling speed according to the current density of smelted metal in a liquid state and the size of a crystallizer, the ingot pulling speed is sent to a controller, and the controller sends an ingot pulling signal to an ingot pulling system, sothat the purposes of making the ingot pulling speed accurately matched with the smelting speed and improving the ingot casting quality are achieved.
