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 comprises a furnace cover body, the furnace wall of the furnace cover body is formed by welding water pipes, a furnace cover upper hole is formed in the upper portion of the furnace cover body, and a refractory furnace cover is fixed above the furnace cover upper hole, specifically, a furnace cover seat is fixed to the lower portion of the refractory furnace cover and fixed to the upper end face of the furnace cover upper hole, and three electrode holes are formed in the refractory furnace cover. And an electrode bar is fixed in each electrode hole in a penetrating manner. And a furnace cover seat is welded at the lower part of the fire-resistant furnace cover and is welded on the upper end surface of the furnace cover upper hole. Compared with the prior art, the fire-resistant furnace cover has the technical effects that the fire-resistant furnace cover is arranged above the furnace cover upper hole, so that steel slag which is originally adhered to the lower end surface of the fire-resistant furnace cover is adhered to the electrode bar, electricity connection can be avoided, a water pipe cannot be burnt through, and water leakage of the furnace cover is avoided.
