Abstract
The utility model relates to a fire-proof electrode seal ring for a zirconia electric arc furnace, which comprises three fire-proof seal rings (2), wherein, the three fire-proof seal rings (2) forming a group are uniformly distributed on an electric arc furnace lid (1); each fire-proof seal ring made of a fire-proof material adopts a solid ring-shaped structure; zirconium corundum can be used as the fire-proof material and can be processed through compression moulding; and each fire-proof seal ring (2) is fixed on the electric arc furnace lid (1) by a group of pressure plates (3) through bolts (4). An electrode (5) penetrates through electrode holes formed in the centers of the fire-proof seal rings (2), so that the risks of electric leakage and arc strike caused by the breakage of insulating material can be avoided effectively; in addition, the structure of components is simple, and the disassembly is convenient.
Description
Technical field:
The utility model relates to the arc furnace electrode protector, specifically is a kind of electrocast refractories electrode sealing-ring that is used for the zirconium white melting.
Background technology:
The a large amount of volatilization loss heats of flue gas when preventing arc melting are installed a metal water cold electrode circle in the electrode hole upper end usually, and internal diameter is more smaller than electrode hole, is welded into ring sleeve with steel plate, interior logical water coolant, the effect that can prolong electrode collar and bell life-span.But in actual applications, still have some drawbacks, long-time use can cause insulation layer resistance to descend, in case take place to beat the arc phenomenon, water cooling tube can be punctured, and causes leaking, and greatly influence is produced.In addition, in hot environment, especially the zirconium white smelting temperature is up to more than 2800 degrees centigrade, and can produce a large amount of high-temperature flue gas during melting, and most flue gases are overflowed from electrode hole, electrode sealing-ring to metal material produces the intensive erosion action, the part that comes off can be polluted zirconium liquid, so cause electrode collar frequently to be changed, not only shortens equipment life, and delaying man-hour, influence is produced.
The utility model content:
The utility model purpose is exactly to beat the arc seepy question for what solve that the water-cooling metal electrode sealing-ring exists, and the fire-resistant sealing-ring of a kind of zirconium white arc furnace electrode that provides is fixed on the bell by follower bolt, and contact surface need not to fill up insulating material.
Effective effect of the present utility model is:
Effectively eliminated the hidden danger of leaking that the water cooled electrode circle exists, good in addition heat-insulating property can protect heat to scatter and disappear, and avoids the water-cooled process to take away a large amount of heats, plays the effect of economize on electricity.Refractory material itself also can bear high temperature erosion, and loading and unloading are simple, are convenient for changing maintenance, improve operating rate.
Description of drawings:
Fig. 1 is electric furnace electrode sealing-ring mounting plane figure;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment:
As shown in Figure 1, the fire-resistant sealing-ring of a kind of zirconium white arc furnace electrode that the utility model provides, comprise uniform one group of three fire-resistant sealing-ring 2 that is arranged on the electric arc furnace bell 1, each fire-resistant sealing-ring is made solid ring texture by refractory materials, refractory materials can be selected zircon corundum compression moulding for use, and each fire-resistant sealing-ring 2 is fixed on the electric arc furnace bell 1 by one group of four pressing plate 3.
As shown in Figure 2, pressing plate 3 usefulness bolts 4 are fixed on the bell, and electrode 5 passes from the electrode hole at fire-resistant sealing-ring 2 centers, can effectively avoid beating because of the electric leakage that the insulating material breakage causes the risk of arc, and this block construction is simple, convenient disassembly.
Claims (1)
1. the fire-resistant sealing-ring of zirconium white arc furnace electrode, comprise the one group of fire-resistant sealing-ring (2) that is arranged on the electric arc furnace bell (1), it is characterized in that: each fire-resistant sealing-ring is made solid ring texture by refractory materials, each fire-resistant sealing-ring (2) is fixed on the electric arc furnace bell (1) by bolt (4) by one group of pressing plate (3), and electrode (5) passes from the electrode hole at fire-resistant sealing-ring (2) center.
