Hold-down gear of submerged arc furnace electrode holder and submerged arc furnace electrode holder

Abstract

The present invention belongs to the metallurgical device technology field, and concretely relates to a hold-down gear of a submerged arc furnace electrode holder and a submerged arc furnace electrode holder. The device comprises a flange cover, an extension element, an elastic corrugated pipe, a cooling pipe and a copper content element extrusion part. Two ends of the elastic corrugated pipe are respectively in seal connection with the extension element and the flange cover to form a holding cavity among the flange cover, the extension element and the elastic corrugated pipe, the cooling pipe is arranged in the holding cavity, the copper content element extrusion part is connected with the end portion, far away from the elastic corrugated pipe, of the extension element, the flange cover is provided with an oil hole, an inlet opening and an outlet opening, the oil hole is connected with the holding cavity, and the inlet opening and the outlet opening are respectively connected with two ends of the cooling pipe. The hold-down gear can transmit the heat of the high-temperature hydraulic oil in the elastic corrugated pipe to the outside to prevent the high-temperature hydraulic oil from deterioration in the elastic corrugated pipe and from the corrosion of the elastic corrugated pipe.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to a pressing device for an electrode holder of a submerged arc furnace and an electrode holder for a submerged arc furnace. Background technique [0002] The electrode holder is the core component of the submerged arc furnace for producing materials such as ferroalloy, industrial silicon, calcium carbide and yellow phosphorus. It is not only affected by the conduction heat of high-temperature gas, radiant heat of arc, and conduction heat of copper tiles, but also the strong magnetic field or eddy current generated by the electrode current also affects the normal operation of the controller. [0003] The function of the electrode holder for submerged arc furnace is to firmly press the copper tile on the electrode, transmit the external strong current to the electrode and cooperate with the pressing and lifting operation of the electrode, so as to realize ...

AI Technical Summary

Problems solved by technology

In the electrode holder for submerged arc furnaces, the bellows-type pressing device for pressing the copper tile and coordinating with the electrode pressing operation, because of long-term work in a high-temperature environment, the high-temperature hydraulic oil retained in the bellows often deteriorates and then corrodes The problem of oil leakage caused by the bellows leads to a short service life of the pressing device, a heavy workload for inspection and maintenance, and an increase in the cost of use
