Description

Technical Field

[0001] The invention relates to the technical field of electrode processing for industrial silicon electric furnaces, in particular to an electrode core-cutting machine tool. Background Art

[0002] my country's industrial silicon production uses quartz ore (mainly silicon dioxide) as raw material and carbonaceous materials as reducing agents. The extraction principle is SiO2+2C → Si+2CO. The reducing agents were mainly charcoal, petroleum coke, and bituminous coal in the early days. At present, most of my country's industrial silicon furnaces use carbon electrodes (carbonaceous electrodes and graphite electrodes) as reducing and conductive materials. The existing graphite electrodes are made into electrode monomers with head ends and hole ends by turning the two ends of the electrode blank. At present, in the processing of the electrode monomer, the existing processing technology will produce a large amount of graphite powder and a small amount of graphite fragments. Since the market price of graphite fragments is much higher than the market price of graphite powder, and graphite fragments can be used again in the preparation of electrode blanks, and the demand for graphite powder in the preparation of electrode blanks is relatively small, the preparation of electrode blanks currently often requires the purchase of more graphite fragments, resulting in higher production costs. Affected by the existing processing technology of electrode monomers, not only is the processing efficiency low and the production of a single product takes a long time, but a large amount of graphite powder is also generated. Since these graphite powders are not fully used in the preparation of electrode blanks, they not only accumulate and occupy funds and storage space, leading to increased costs and idle resources, but are also easily scattered and pollute the surrounding environment, posing a greater risk of environmental pollution. Summary of the invention

[0003] The purpose of the present invention is to provide an electrode core-cutting machine tool, which overcomes the shortcomings of the above-mentioned prior art and can effectively solve the problems of low efficiency, long time consumption, large amount of graphite powder produced in the existing manufacturing process of graphite electrodes for industrial silicon electric furnaces, and easy backlog of graphite powder, which occupies funds and storage space and poses a risk of environmental pollution.
