Problems solved by technology

[0002] The traditional submerged arc furnace uses forged copper tiles to transmit electricity to the electrodes. Due to the poor cooling effect of the copper tiles, the resistance is relatively large, and the power loss is large during the transmission process.
Also because the copper tile is in direct contact with the furnace fire, the copper tile is easy to burn out, and because the copper tile is in direct contact with the electrode, it is easy to puncture the fire when the electrode is lowered, and burn the copper tile. It is a vulnerable part that is often replaced in the submerged arc furnace.
On the one hand, the electric efficiency is low, and on the other hand, the submerged arc furnace is thermally cut off due to the replacement of copper tiles; resulting in loss of furnace shutdown, low production efficiency and high production costs

Embodiment Construction

[0013] Such as figure 1 and figure 2 Shown: an improved submerged arc furnace electrode feeder; including electrodes 3, graphite lining 9, a circulating cooling water jacket 6 with a conductive plate 5 on the inner ring and a holding device; the outer side of the lower part of the inner ring of the circulating cooling water jacket 6 A support base 10 is fixedly connected with a stud 8, and a graphite lining 9 is installed above the support base 10.

[0014] Compared with the technology of the patent No. 200720153032.0 described in the background technology, the support seat at the lower end of the circulating cooling water jacket is changed to a detachable single body. After the submerged arc furnace runs to a certain period, due to the continuous oxidation of graphite lining 9, When the volume is deformed and cannot be in close contact with the electrode 3, it needs to be replaced. For the convenience of replacement, the supporting base 10 is removed, and after a new grap...

Abstract

The invention relates to a submerged arc furnace for smelting products such as silicon metal, yellow phosphorus, nickel and various iron alloys, specifically an improved submerged arc furnace electrode feed device. The device comprises electrodes, graphite linings, circulating cooling water jackets of which inner rings are equipped with conductive boards, and enclasping devices. Support bases are fixedly connected at outer sides of the inner rings of the circulating cooling water jackets. The graphite linings are mounted on the support bases. The enclasping devices are pressure rings. The pressure rings are sleeved at peripheries of the circulating cooling water jackets. Two magnetism isolation plates are mounted on the pressure rings. According to the device, the technical problems that graphite lining replacing operations are high in difficulty and are inconvenient are solved. The pressure rings are equipped with the magnetism isolation plates made of stainless steel, therefore, the magnetic field generated in operation process of the submerged arc furnace is isolated, the electrical efficiency is improved, and moreover, the thermal efficiency of the submerged arc furnace is improved.

Description

technical field [0001] The invention relates to a submerged arc furnace for smelting metal silicon, yellow phosphorus, nickel and various ferroalloys, especially an improved submerged arc furnace electrode feeder. Background technique [0002] The traditional submerged arc furnace uses forged copper tiles to transmit electricity to the electrodes. The copper tiles have a poor cooling effect, so the resistance is relatively large, and the power loss is large during the transmission process. Also because the copper tile is in direct contact with the furnace fire, the copper tile is easy to burn out, and because the copper tile is in direct contact with the electrode, it is easy to puncture the fire when the electrode is lowered, and burn out the copper tile. It is a vulnerable part that must be replaced frequently in the submerged arc furnace. On the one hand, the electric efficiency is low, and on the other hand, the submerged arc furnace is thermally cut off due to the repla...
