PRE-MELTING EQUIPMENT FOR PRE-MELTING SILICON BEFORE FEEDING IT INTO THE MAIN METAL COIL AND METHODS FOR OPERATING THIS EQUIPMENT

Abstract

The invention relates to a pre-melting apparatus for pre-melting silicon before feeding it into the main melting crucible, capable of accurately measuring the amount of molten silicon introduced into the crucible for developing ingots, thereby effectively controlling the input amount, and a method for controlling this apparatus. According to one design of the invention, the invention relates to a pre-melting apparatus for pre-melting silicon before feeding it into the main melting crucible, comprising: a pre-melting crucible for feeding molten silicon into the main melting crucible in which ingots are developed after heating solid silicon material to become molten silicon;A module for moving the crucible if the pre-melting crucible is structured to tilt the crucible to one of the first positions where the crucible contains solid silicon or molten silicon, or a second position where molten silicon in the crucible flows into the main crucible; and a controller to control the crucible moving module.
