AI Technical Summary

Technical Problem

The existing water-cooled furnace cover is prone to short circuits between the electrode rod and the water pipe due to splashing slag during the smelting process, which can cause the water pipe to burn through and leak water, resulting in an accident.

Method used

In the design of the water-cooled furnace cover, the lower part of the refractory furnace cover is fixed with a furnace cover seat, which is welded to the upper end face of the hole on the furnace cover. Electrode holes are provided on the refractory furnace cover, and electrode rods are inserted into the electrode holes to prevent steel slag from directly adhering to the lower end face of the refractory furnace cover.

Benefits of technology

This effectively avoids electrical short circuits between the electrode rod and the water pipe, prevents the water pipe from burning through, avoids water leakage from the furnace cover, extends the service life of the furnace cover, improves the continuity and stability of production, and reduces equipment maintenance costs.

Abstract

A water-cooled furnace cover, including furnace cover body, the furnace wall of furnace cover body is welded with water pipe, the top of which is provided with furnace cover upper hole, the top of furnace cover upper hole is fixed with refractory furnace cover, specifically: the lower part of refractory furnace cover is fixed with furnace cover seat, and the furnace cover seat is fixed on the upper end surface of furnace cover upper hole, three electrode holes are arranged on the refractory furnace cover, and one electrode rod is fixed in each electrode hole.The lower part of refractory furnace cover is welded with furnace cover seat, and the furnace cover seat is welded on the upper end surface of furnace cover upper hole.Compared with the prior art, the technical effect of the utility model is that the refractory furnace cover is arranged above the furnace cover upper hole, so that the steel slag originally adhered to the lower end surface of the refractory furnace cover is adhered to the electrode rod, the connection of electricity can be avoided, the water pipe cannot be burned through, and the furnace cover is prevented from leaking water.
