Abstract
The utility model discloses an immersed nozzle heating device relates to the continuous casting production field, provide one kind need not to dismantle immersion nozzle under the mouth of a river also can be to its immersed nozzle heating device who goes on toasting. Immersed nozzle heating device includes mouth of a river pipe and breathing pipe, and mouth of a river pipe one end is mouth of a river entry, and the other end seals, and mouth of a river intraduct space holds chamber, breathing pipe and mouth of a river union coupling for the mouth of a river. The method that adopts this device to toast the mouth of a river does: install immersed nozzle heating device in the position of toasting of centre package, mouth of a river pipe box is adorned down outside the mouth of a river to use thermal -insulated cotton with mouth of a river pipe with down between the mouth of a river space locate to seal up. The breathing pipe is connected with air extraction equipment and is connected. Bao xiaohuo toasts about 30 minutes backs in the middle of treating, opens air extraction equipment. Air extraction equipment is with the mouth of a river under flame and the hot gas flow suction of toasting in the centre package to the realization is toasted the lower mouth of a river.
Description
Technical field
The utility model relates to even casts production field, particularly relates to a kind of immersed nozzle heating device.
Background technology
Tundish molding casting applies the most general pouring type in modern even casting, and when adopting split type submerged nozzle, under usual submerged nozzle, mouth of a river baking to be toasted in Special Baking tank, need dismantle the lower mouth of a river. Before centre is unwrapped and is watered, under installing submerged nozzle, the mouth of a river is to tundish bottom, increase and open the setup time before watering, setup time is excessively grown and causes mouth of a river temperature cooling decline, can affect and hold normally carrying out of watering, cause dead stream even to open time serious to water unsuccessfully, thus even casting open water before further shortening open water before setup time be necessary.
Practical novel content
The technical problems to be solved in the utility model is: provide a kind of without the need to dismantling the immersed nozzle heating device that it also can be toasted by the mouth of a river under submerged nozzle.
The technical scheme adopted for solving the problem is: immersed nozzle heating device comprises pouring spout and air suction pipe, and pouring spout one end is nozzle inlet, and the other end is closed, and pouring spout internal space is mouth of a river cavity volume, and air suction pipe is connected with pouring spout.
Further: pouring spout quantity is at least two pieces, air suction pipe comprises the inspiratory limbs and an extraction equipment pipe connecting that an air-breathing is responsible for, quantity is identical with pouring spout quantity, inspiratory limbs and extraction equipment pipe connecting are all connected with air-breathing supervisor, and an inspiratory limbs is connected with a pouring spout.
Further: extraction equipment pipe connecting is provided with valve.
Further: pouring spout, inspiratory limbs, air-breathing supervisor and extraction equipment pipe connecting are made by steel pipe, and pouring spout internal diameter is 200mm, and inspiratory limbs internal diameter is 50mm, air-breathing supervisor's internal diameter is 100mm, and extraction equipment pipe connecting internal diameter is 30mm.
The beneficial effects of the utility model are: the online baking that 1, can realize split type submerged nozzle, save open water before install under time at the mouth of a river, shorten and open and water front setup time, reduce tundish temperature loss and mouth of a river temperature loss, ensure and open carrying out smoothly of watering.
2, reduce the duration of service of mouth of a river Special Baking tank, save combustion gas. Reduce costs.
Accompanying drawing explanation
Fig. 1 is immersed nozzle heating device vertical view;
Fig. 2 is immersed nozzle heating device side-view;
Fig. 3 is immersed nozzle heating device using state figure;
Figure is labeled as: pouring spout 1, nozzle inlet 1-1, mouth of a river cavity volume 1-2, air suction pipe 2, inspiratory limbs 2-1, air-breathing supervisor 2-2, extraction equipment pipe connecting 2-3, valve 3, tundish 4, the lower mouth of a river 5.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is illustrated further.
As depicted in figs. 1 and 2, immersed nozzle heating device comprises pouring spout 1 and air suction pipe 2, and pouring spout 1 one end is nozzle inlet 1-1, and the other end is closed, and pouring spout 1 internal space is mouth of a river cavity volume 1-2, and air suction pipe 2 is connected with pouring spout 1.
The method adopting this device to toast the mouth of a river is: the baking position that immersed nozzle heating device is arranged on tundish 4, and pouring spout 1 cover installs to outside the lower mouth of a river 5, and uses heat insulation foam by gap good seal between pouring spout 1 and the lower mouth of a river 5. Air suction pipe 2 is connected with extraction equipment and is connected. After about 30 minutes, extraction equipment is opened until the little fire baking of tundish. Extraction equipment is by the baking flame in tundish 4 and the mouth of a river 5 under hot gas flow suction, thus realizes the baking to the lower mouth of a river 5, and tundish 4 baking turns off extraction equipment after terminating, and rises tundish 4, opens to cast position, falls tundish 4, can open and water after centering.
In aforesaid method, it is necessary to lifting tundish 4, therefore this device is applicable to the occasion that tundish flatcar has liftable function.
The lower mouth of a river 5 has multiple, in order to make multiple lower mouth of a river 5 toast simultaneously, can adopt multiple devices during baking. Also can by as follows for this device specific design: pouring spout 1 quantity is at least two pieces, inspiratory limbs 2-1 and the extraction equipment pipe connecting 2-3 that air suction pipe 2 comprises an air-breathing supervisor 2-2, quantity is identical with pouring spout 1 quantity, inspiratory limbs 2-1 and extraction equipment pipe connecting 2-3 is all responsible for 2-2 with air-breathing and is connected, and an inspiratory limbs 2-1 is connected with a pouring spout 1. Arranging multiple pouring spout 1 can enable this device toast multiple lower mouth of a river 5 simultaneously.
In order to convenient control air-flow break-make, the extraction equipment that when avoiding toasting, frequent operating distance is far away, extraction equipment pipe connecting 2-3 is provided with valve 3. Obvious valve 3 is relatively near apart from tundish, is convenient to switch to control beginning and the termination of baking.
Pouring spout 1, inspiratory limbs 2-1, air-breathing supervisor 2-2 and extraction equipment pipe connecting 2-3 recommends to make by steel pipe. Size according to the common lower mouth of a river, show that the concrete size of each pipe is recommended as follows: pouring spout 1 internal diameter is 200mm, and inspiratory limbs 2-1 internal diameter is 50mm, and air-breathing supervisor's 2-2 internal diameter is 100mm, and extraction equipment pipe connecting 2-3 internal diameter is 30mm.
