A gripper guiding device

Abstract

The invention discloses a holder guide device which is mounted on an electrode of a submerged arc furnace and comprises a pressure ring, a plurality of guide mechanisms and a guide baffle; the guide mechanisms are installed on the pressure ring at equal-angle and interval manners and comprise fixing plates, insulating material layers and guide wheel seats, the fixing plates are fixedly installed at the upper end of the pressure ring, the insulating material layers are arranged on the outer sides of the fixing plates, the guide wheel seats are arranged on the outer sides of the insulating material layers, and guide wheels are installed on the guide wheel seats; the guide wheels protrude out of the surface of the outer side of the pressure ring by a safe distance; and guide baffles are trackplates extending upwards in the electrode movement direction and are installed on the periphery of an electrode insertion opening of a furnace lid in a manner of corresponding to the guide mechanisms, insulating layers are arranged between the bottoms of the guide baffles and the furnace lid, the inner side faces of the guide baffles are flush with the inner side wall of a motor opening of the furnace lid, and a reserved interval distance is reserved between the inner side face of each guide baffle and the corresponding guide wheel. The holder guide device has the advantages that arc strikingaccidents caused by electrode deviation can be effectively reduced, and the production safety and efficiency of the submerged arc furnace are improved.

Description

technical field [0001] The invention relates to an electrode-clamping technology of a submerged arc furnace, in particular to a guide device for a gripper. Background technique [0002] As an important component of the electrode holding system of the submerged arc furnace, the pressure ring is not only the main conductive part of the electrode holder of the submerged arc furnace, but also the key part of holding the electrode and the elastic electrode. Its function is to press the copper tile and hold the electrode tightly, so that the current passes through the copper tile evenly through the electrode and enters the furnace; to ensure that the pressure of the electrode is the same as that of each copper tile, and the copper tile is not easy to arc. The advantages and disadvantages of its structure and performance will directly affect the reliability and operation rate of submerged arc furnace operation. Because of the very harsh working environment, all components work und...

AI Technical Summary

Problems solved by technology

After the electrode is broken, the electrode paste leaks, and it needs to be re-roasted, resulting in a long-term power outage of the submerged arc furnace, which affects production

Corresponding point suspenders are also deformed due to high temperature environment, causing pressure rings and copper tiles to shift, resulting in uneven electrode current transmission

[0004] The electric furnace needs to be dismantled and replaced due to tripping and maintenance, the pressure ring, bellows, copper tiles and insulation components, etc. During this period, the temperature of the furnace cover is high, and there are many insulation points, which makes the repair task difficult and difficult.

Therefore, the electric furnace will be cut off for a long time, which will seriously affect the production efficiency.
