Abstract
The utility model relates to a water-cooled electrode seal ring for a zirconium oxide electric arc furnace. A set of water-cooled electrode seal rings (2) are arranged on a furnace cover (1), a metal casing (5) is welded on each water-cooled electrode seal ring (2), each metal casing (5) is provided with a small asbestos gasket (7), large asbestos gaskets (9) are arranged below the water-cooled electrode seal rings (2) and the metal casings (5), a mica insulation sleeve (8) is arranged inside each metal casing, and a bolt (6) passes through the small asbestos gaskets (7), the mica insulation sleeves (8) and the large asbestos gaskets (9) to be fixed on the furnace cover. The positions of the electrode seal rings and the furnace cover are relatively fixed without movement space within the periphery, so as to effectively prevent an electrode (4) from driving the electrode seal rings to move when the electrode moves, avoid arc strike and greatly prolong the service life of the furnace cover and the electrode seal rings.
Description
Technical field:
The utility model relates to the zirconic electric arc furnaces of a kind of melting, particularly the water cooled electrode sealing ring on the electric arc furnaces bell.
Background technology:
The zirconic electric arc furnaces bell of melting is generally brick formula, all adopts refractory brick to build by laying and forms, and temperature is very high near the bell electrode, and refractory brick easily weathers and comes off, and influences product purity in the electric arc furnaces thereby enter.
In order to overcome the above problems, can select the making electric arc furnaces bell of metal material for use, usual way is that one group of electrode hole is set on bell, each electrode hole embeds installs a coreless armature sealing ring, interior water flowing is cold, electrode sealing ring effectively control electrode does not contact with bell, has good position-limiting action.But bell is approaching with electrode, the easy generation beaten the arc phenomenon when contacting, so arc furnace electrode must be isolated with bell.For playing insulation effect, between electrode sealing ring and bell, increase one deck asbestos washer.But the electrode sealing ring of this structure is loosening when vertical direction moves up and down with electrode easily, and then forms the space between electrode sealing ring and bell, and insulating properties descends, and forms easily and beats the arc phenomenon, very easily will be with waterstop ring to punch, and causes and leaks, and influence is produced.
The utility model content:
The purpose of this utility model is exactly the shortcoming that the electrode sealing ring is loosening easily, arc is beaten in generation that exists in the prior art in order to solve, and a kind of energy that provides is eliminated the zirconia electric arc furnaces water cooled electrode sealing ring of beating arc.
To achieve these goals, the utility model has adopted following technical scheme:
Zirconia electric arc furnaces water cooled electrode sealing ring, comprise the electric arc furnaces bell, uniform on the bell one group of water cooled electrode sealing ring is set, it is characterized in that: connect 3-6 metal sleeve on each water cooled electrode sealing ring, each is respectively equipped with the asbestos small washer above the metal sleeve, below water cooled electrode sealing ring and metal sleeve, be provided with the asbestos large washer, be provided with the mica insulation cover in the metal sleeve, be provided with in each metal sleeve and be fixed on the bell after a bolt passes asbestos small washer, mica insulation cover and asbestos large washer.
Advantage of the present utility model is: adopt insulation system, by bolt the water cooled electrode sealing ring is fixed on the bell, the crack of not boxing out can effectively completely cut off contacting of electrode and bell, thereby avoid beating the arc phenomenon, has prolonged the service life of electric arc furnaces.In addition, this fixture structure is simple, and convenient disassembly is convenient to check that maintenance can effectively be enhanced productivity.
Description of drawings:
Fig. 1 is a vertical view of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
As shown in Figure 1, a kind of zirconia electric arc furnaces water cooled electrode sealing ring that the utility model provides comprises electric arc furnaces bell 1, uniform on the bell three water cooled electrode sealing rings 2 is set, and provides the turnover cooling water by cold water pipe 3 to it.Four metal sleeves 5 of welding on each water cooled electrode sealing ring 2.
As shown in Figure 2, each is respectively equipped with asbestos small washer 7 above the metal sleeve 5, below water cooled electrode sealing ring 2 and metal sleeve 5, be provided with asbestos large washer 9, be provided with mica insulation cover 8 in the metal sleeve, be provided with in each metal sleeve 5 and be fixed on the bell after a bolt 6 passes asbestos small washer 7, mica insulation cover 8 and asbestos large washer 9.
After the bolted, electrode sealing ring and bell position relative fixed all do not have activity space up and down, prevent from effectively to drive the activity of electrode sealing ring when electrode 4 from moving, and avoid occurring beating the arc phenomenon, have greatly prolonged the life-span of bell and electrode sealing ring.
