摘要:
Method and apparatus for removing bubbles from a molten substrate. The molten substrate from a furnace passes through a downtube to reach additional manufacturing tools, such as an extrusion bushing. One or more ultrasonic sensors are arranged along the downtube. The ultrasonic sensor(s) transmit ultrasonic energy into the molten substrate and measure a characteristic of the ultrasonic energy, such as a propagation time for the ultrasonic energy to be reflected back to the ultrasonic sensor(s). A bubble is detected when a change in the characteristic of the ultrasonic energy is detected. When a bubble is detected, flow through the downtube is diverted to a duct to remove a slug of molten substrate that includes the bubble.

从熔融基材除去气泡的方法和装置。 来自熔炉的熔融基材通过下管,以达到额外的制造工具,例如挤出套管。 沿着下管布置一个或多个超声波传感器。 超声波传感器将超声波能量传递到熔融基底中,并测量超声能量的特性,例如超声能量被反射回超声波传感器的传播时间。 当检测到超声能量的特性的变化时,检测到气泡。 当检测到气泡时,通过下管的流动被转移到管道以移除包括气泡的熔融基底的块状物。
