Definitions

the invention relates to a refractory spout for a metallurgical vessel, in particular for Melting steel, with a through opening having an upper and a lower end and an inner wall enclosing the passage opening on the side.
Such spouts are widely known in metallurgy (DE 195 26 970 A1, DE 196 18 605 A1, DE 196 51 533 A1, DE 196 51 534 A1, EP 379 647 A2).
a problem with these spouts it is that when the hot molten metal comes in, thermal stresses can be destroyed or that metal on the inner wall of the spouts is deposited.
the spouts are usually preheated. Gas burners or induction heaters are used for this. For example with gas burners it is necessary that the preheating phase before the melt flows into the Spout is stopped to remove the burner from the flow area in time can. During this time, however, the spout cools down, so that the mentioned Problems cannot be completely eliminated.
the invention is based, to improve the known spouts and the task To design preheating in such a way that destruction due to thermal tension or freezing metal melt on the inner wall of the spout can be largely avoided.
thermal insulating material cardboard or a material with a melting point below the Melting point of steel is. Such material may cause it to freeze Metal melt after dissolving or melting the material with the melt flow the spout is rinsed out and does not clog it.
thermal insulating material is fibrous or formed by spraying.
the heater is expediently made of steel. Even metals with a lower one Melting point as steel may be suitable. When the spout is used for molten steel the heater dissolves as it passes through the melt, so that can flow freely through the spout. Possibly freezing on the heater first Material is dissolved again and rinsed out of the spout.
the heating and / or the thermally insulating material by at least two extending in the longitudinal direction of the passage opening, side by side in the circumferential direction arranged parts is formed, since such an arrangement is easier can be made. It makes sense that the two parts are designed to be uniform to simplify manufacturing. The parts should touch each other or mechanical (or electrical) contact with each other.
a heater 2 is arranged in the passage opening 1 of the spout.
the heater has one two-part (see Fig. 2) meandering structure. It is in the spout by means of holding elements 3 hung. These holding elements 3 lie on the upper edge of the spout.
the stoker 2 is made of steel. The preheating phase can extend in time due to its arrangement until the molten metal runs through the spout. When using the spout for molten steel, the heater 2 can be opened and flushed out of the spout.
the heater has 2 electrical contacts 4, of which in only one is shown for the sake of simplicity.
the second contact makes sense arranged at the corresponding end of the second part of the heater 2.
the division into two the heater 2 can be seen in Fig. 2.
the two parts of the heater 2 are at the contact point 5 mechanically and electrically connected to each other.
the inner wall 6 of the spout is formed from zirconium dioxide.
the electrodes 7 are called electrical Contacts 9 led to the outside.
the spout has an outer housing 10 made of steel on the at its upper end of a sintered ring 11 made of ceramic material is limited.
This insulating material 12 and the sintered ring 11 are formed from zirconium dioxide mullite.
