Abstract
The utility model discloses a middle packing is put with streamlined lateral wall. The device includes the long mouth of a river of the long mouth of a river of pouring into the molten steel into, middle package and outflow molten steel, and characterized by the device sets up streamlined lateral wall in the package of centre, and streamlined lateral wall radius is 2 -5m. The utility model discloses a change the shape of lateral wall for the molten steel that flows in centre package weakens the scouring force of barricade, weakens the erosion of resistant material, has improved the pure degree of molten steel, has increased the life of resistant material, and then the life of package in the middle of improving, has reduced middle package and has changed the number of times, and increased and even water the stove number, has improved the quality of wrapping the molten steel in the middle of flowing out simultaneously.
Description
Technical field
The utility model relates to single flow channel formula eddy-current heating tundish device, particularly a kind of tundish device with streamlined sidewall in iron and steel production.
Background technology
Tundish metallurgy is the outer metallurgical technology of a special stove, is from the melting of steel and is refined to and makes guarantee this production procedure of solid-state continuous casting billet and obtain the key link of excellent steel.In order to ensure that continuous casting carries out and sequence casting smoothly, molten steel must have enough cleanliness factors, and molten steel component will as far as possible accurately control, and molten steel temperature will keep stable within the sufficiently long time.Therefore as last refractory container in the smelting process of steel, the metallurgy action of tundish receives increasing concern.
Channel-type eddy-current heating tundish effectively can compensate the temperature drop of tundish molten steel and make its homogeneous temperature, effectively can improve molten steel cleannes in tundish simultaneously, reduces non-metallic inclusion.There is homogeneous heating, efficiency be high, equipment is simple, reduced investment, safe and reliable to operation, convenient operating maintenance there is the advantages such as metallurgical effect is good.In recent years, expand a large amount of academic research about channel-type eddy-current heating tundish metallurgy, a lot of achievement in research has been converted into the technical measures of practical application in production, as: tundish structure designs; Refractory material and covering slag control; Flow control technique; Suppress secondary oxidation etc.This illustrates that metallurgical boundary is own through receiving channel-type eddy-current heating tundish metallurgy concept, and becomes the technology in practical operation.
Single flow channel formula eddy-current heating tundish is subject to the restriction of heater and inner chamber size, cause channel outlet distance sidewall very near, the molten steel flow velocity of flow pass again quickly, the resistance to material of oppose side wall washes away and corrodes seriously, use streamlined sidewall instead and can reduce molten steel washing away tundish sidewall, reduce molten steel and the degree of purity that effectively can improve molten steel is washed away to barricade.Streamlined sidewall can reduce the scope in dead band simultaneously, and then promotes the removal of molten steel temperature, uniform composition and field trash, and then improves slab quality.
Patent announcement CN104249149A, discloses a kind of channel-type eddy-current heating tundish and casting method thereof, and this device and method can effective removal of inclusions and even molten steel temperature.But because its sidewall is linear pattern sidewall, comparatively near apart from passage delivery port, so molten steel washes away very large to the sidewall watering steel chamber, be unfavorable for the service time of tundish.
Patent announcement CN104249148A, discloses a kind of channel-type tundish and differential pre-heating mean, and the method makes passage and the mouth of a river reach good pre-heat effect.But it is not high to the opposing of molten steel scouring capability that this device is linear pattern sidewall, the resistance to material of sidewall is easily etched, dead band is comparatively large simultaneously, can not better ensure the degree of purity of molten steel.
Patent announcement CN203917885U, discloses a kind of tundish device with streamlined barricade, and this device can make the scouring force of molten steel to barricade flowed weaken by changing barricade shape, and the erosion of molten steel to resistance to material is weakened.But this device adopts streamlined barricade to weaken washing away of molten steel, do not adopt streamlined sidewall, and single current tundish does not have barricade, can not adopt this device.
Summary of the invention
The utility model provides a kind of tundish device with streamlined sidewall.
A kind of tundish device with streamlined sidewall that the utility model provides comprises: the long nozzle injecting the long nozzle of molten steel, tundish and outflow molten steel, it is characterized in that this device arranges streamlined sidewall in tundish, streamlined sidewall radius is 2-5m.
The utility model is compared with existing same device, its beneficial effect is embodied in: by changing the shape of sidewall, the scouring force of molten steel to barricade flowed in tundish is weakened, the erosion of resistance to material is weakened, improves the degree of purity of molten steel, add the service life of resistance to material, and then improve the service life of tundish, decrease tundish and change number of times, and add casting sequence, improve the quality flowing out tundish molten steel simultaneously.
