Abstract

This utility model discloses a copper tile electrode preheating device for an industrial silicon furnace, comprising four protective shells, each housing an electrode assembly with electrodes mounted thereon. The four electrodes are arranged in a cross shape, with each pair corresponding to the other. A slider is fixed to one side of two of the protective shells, and two guide rails are provided on one side of each slider. A slider on one side engages with the two guide rails on the same side, and the slider is threaded onto the guide rails using two studs. This copper tile electrode preheating device not only allows for customization to different furnace layouts, enhancing its adaptability, but also enables flexible selection and placement based on actual conditions. This significantly improves the adequacy of the electrode layout, ensuring thorough and comprehensive heating during preheating, greatly shortening preheating time, increasing processing efficiency, improving processing quality, and enhancing practicality and stability.
