Abstract
The utility model relates to a continuous casting air-permeable upper nozzle with electric heating functions, which comprises an upper nozzle body and a heating device. Air-permeable materials are arranged at the top end of the upper nozzle body, a seal argon ring is arranged at the bottom end of the upper nozzle body, and the heating device is wrapped at the outer side of the upper nozzle body. The upper nozzle has reasonable structural design, is convenient to use, and can be widely used in the technical field of steel making.
Description
Technical field
The utility model relates to a kind of steelmaking equipment, particularly relates to a kind of continuous casting ventilating filling pipe end with electric heating function.
Background technology
The main material of making continous casting sprue is graphite and aluminium oxide, also contain a spot of silica and carborundum etc., actual measurement discovery continuous casting tundish upper nozzle temperature is having only after the baking about 750 ℃, its chief reason be the continuous casting tundish in bake process, the gas burner in the tundish can't reach tundish upper nozzle or its flame intensity of drawing is lower.In the process of continuous casting aluminum killed steel, the field trash alundum (Al in regular meeting's generation steel sticks to the phenomenon on the inwall of the mouth of a river, causes the continuous casting tundish upper nozzle to stop up, and causes the interruption of production process.Not only influence output, and if tamper peel off mouth of a river wall, sneak in the molten steel in the crystallizer, also can cause the deterioration of molten steel cleanliness factor, have potential risks for the quality of the inside of strand product.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, and is easy to use, the continuous casting ventilating filling pipe end with electric heating function of high insulating effect.
In order to address the above problem, the utility model by the following technical solutions:
A kind of continuous casting ventilating filling pipe end with electric heating function comprises filling pipe end body and heater, and filling pipe end body top is provided with gas permeable material, and filling pipe end body bottom is provided with sealing argon gas ring, and the filling pipe end body outside is enclosed with heater.
Described heater comprises electrode central layer, two-layer ceramic insulation board and lead, and the two-layer ceramic insulation board is enclosed in the filling pipe end body outside in the form of a ring, is provided with the electrode central layer between the two-layer ceramic insulation board, and the electrode central layer is connected with lead.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model mouth of a river is in continuous casting tundish bake process, adopt electrically heated mode that self is heated, its temperature is reached more than 1000 ℃, prevent from mouth of a river inwall the cold steel phenomenon of bonding to take place because temperature is crossed low, thereby avoided filling pipe end to stop up, the production of guarantee continuous casting is carried out smoothly.
2, the utility model adopts heated by electrodes, and it is accurate to add thermal target, and temperature is steady, and it is little to fluctuate; In the process that adopts heated by electrodes, still can add and use the coal gas of tundish baking to toast the temperature height of baking; After tundish stopped coal gas baking, it still can carry out electrical heating handled, and had overcome to stop the excessive defective of its temperature drop behind the coal gas baking tundish.

The specific embodiment
A kind of continuous casting ventilating filling pipe end with electric heating function, as shown in Figure 1 and Figure 2, comprise filling pipe end body 2 and heater, filling pipe end body 2 tops are provided with gas permeable material 1, filling pipe end body 2 bottoms are provided with sealing argon gas ring 5, and filling pipe end body 2 outsides are enclosed with heater.Heater comprises electrode central layer 3, two-layer ceramic insulation board 4 and lead 6, and two-layer ceramic insulation board 4 is enclosed in filling pipe end body 2 outsides in the form of a ring, is provided with electrode central layer 3 between the two-layer ceramic insulation board 4, and electrode central layer 3 is connected with lead 6.
In the continuous casting production scene, the continuous casting tundish adopts normal gas burner to carry out the routine baking, simultaneously, in filling pipe end, draw power lead 6 joints, the rate of heat addition and the heat time heating time of in the tundish bake process, adjusting tundish upper nozzle according to the effect and the heating rate of resistance heated.
