[0020] In this embodiment of the invention, the frame provides the necessary structural support for the entire artificial burn-through device of the industrial silicon submerged arc furnace, ensuring its stability and durability. The copper busbar design optimizes the current transmission path, improving conductivity and thermal efficiency. Compared to the traditional method of using graphite sleeves to hold the electrodes, this embodiment uses conductive steel pipes instead. The conductive steel pipes have superior conductivity, strength, and cost compared to graphite sleeves, significantly improving the conductivity of the artificial burn-through device.

The conductive steel tube includes a fixing component and a clamping assembly. The detachable connection between the clamping assembly and the fixing component makes the replacement of the clamping assembly more convenient and quick, improving operational flexibility and response speed. The walls of the first receiving hole on the clamping assembly and the second receiving hole on the fixing component are tightly fitted to the outer wall of the electrode, which not only increases the contact area with the electrode and ensures that the electrode can be accurately and stably clamped, but also avoids deformation caused by loose contact between the conductive steel tube and the electrode, thus helping to extend the service life of the artificial burn-through device for industrial silicon submerged arc furnaces. This invention utilizes conductive steel pipes to clamp the electrodes. The conductivity and strength of the conductive steel pipes are superior to those of graphite sleeves, significantly improving the conductivity of the manual burn-through device for industrial silicon submerged arc furnaces. It also effectively prevents deformation of the electrode rod conductive clamps due to poor contact with the electrodes or heat exposure at high temperatures, solving the problem of short service life in previous manual burn-through devices for industrial silicon submerged arc furnaces. This ensures long-term stable operation of the burn-through device, reducing the replacement cycle of the electrode rod conductive clamps from 3-5 days to 15-22 days, greatly reducing the number of replacements required by employees. It also reduces material consumption and eliminates the cost of frequent graphite sleeve replacements, demonstrating high practical value. Furthermore, since the working area for replacing the electrode rod conductive clamps is a high-temperature zone, reducing the number of replacements significantly lowers the probability of risk, thereby improving operational safety. The manual operation of the industrial silicon submerged arc furnace burn-through device by employees for burning the furnace eye is highly flexible, allowing for timely adjustments to the angle and direction. This solves the problem of automatic burn-through devices being unable to penetrate deeply into the burning eye, making furnace eye burning operations easier. Attached Figure Description
