Abstract
A tundish base baker nozzle comprises a phi50 seamless steel tube 1, a phi30 seamless steel tube 2, a D40 inner-thread connector 3 and a D25 inner-thread connector 4. The D25 inner-thread connector 4 is parallelly welded to one end of the phi30 seamless steel tube 2. The D40 inner-thread connector 3 is vertically welded to the lateral opening at one end of the phi50 seamless steel tube 1. The phi30 seamless steel tube 2 is welded in the middle of the phi50 seamless steel tube 1. The end, welded with the D40 inner-thread connector 3, of the phi50 seamless steel tube 1 and the end, welded with the phi30 seamless steel tube 2, of the D40 inner-thread connector 3 are identical in direction. The tundish base baker nozzle is simple in process, length-adjustable, economical, good in stability and convenient to use and mount, the flame point of the nozzle is away from the upper steel plate and the lower steel plate of the tundish base, the thermal stress of the steel plates is not destructed, the service life of the tundish base is prolonged, the nozzle is welded be seamless steel plates and less prone to loosening and falling in vibration work environments, and frequent maintenance is avoided.
Description
Technical field
The utility model relates to a kind of burner, a kind of tundish bag of specific design tire roaster burner.
Background technology
What current various liner in dundish bag tire roaster burner great majority adopted is the cast iron burner of casting, this kind of burner complex manufacturing technology, short and thick, heavy, price.Because burner is short, the tight-lipped steel plate above by tundish bag tire roaster of burner, during heating, the flame of burner is on top, cause top and the bottom temperature uneven, upper temp is too high, extremely cold very hot, thermal stress to steel plate is destroyed, aggravate the deformation velocity of steel plate above, temperature of lower is low, unfavorable to the baking of working lining.Burner is that ironcasting assembles, and under long-term vibration working environment, burner is easily loosening, and ironcasting can not be welded to connect again simultaneously, often need to keep in repair, and uses inconvenient.
Therefore, produce a kind of simple in structure, long service life, repair and maintenance is convenient, the tundish bag tire roaster burner that operating efficiency is high, has wide market prospects.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of simple in structure, long service life, repair and maintenance is convenient, operating efficiency is high tundish bag tire roaster burner.
The technical solution of the utility model is achieved in that a kind of tundish bag tire roaster burner, comprise Threaded Connector Coupling and the interior Threaded Connector Coupling of D25 in φ 50 seamless steel pipes, φ 30 seamless steel pipes, D40, in described D25, Threaded Connector Coupling is welded on one end of φ 30 seamless steel pipes in parallel, in D40, Threaded Connector Coupling is vertically welded in the lateral opening hole place of one end of φ 50 seamless steel pipes, described φ 30 seamless steel pipes are welded on φ 50 seamless steel pipe middles, and one end of one end of the interior Threaded Connector Coupling of φ 50 seamless steel pipe welding D40 and the interior Threaded Connector Coupling of φ 30 seamless steel pipes welding D25 is in same direction.
The length that φ 50 seamless steel pipes are stretched out in one end of the described interior Threaded Connector Coupling of φ 30 seamless steel pipe welding D25 is 100mm, and the length that other end φ 30 seamless steel pipes stretch out φ 50 seamless steel pipes is 50mm.
The utlity model has following good effect: this Product Process is simple, length is adjustable, economical and practical.Because burner length is adjustable, burner length can be made according to tundish bag tire height, general burner flame point position is in wrapping tire height 1/3-2/3 place for well, during ventilating coal gas igniting heating, the flame of burner directly enters bag tire lower housing portion, flame has bottom upwards anti-, top and the bottom temperature is even like this, evenly favourable to the baking of working lining, burner flame point is away from bag tire top and bottom steel plate simultaneously, do not destroy the thermal stress of steel plate, and then also can extend the service life of bag tire, burner is to form with seamless Plate Welding, good stability, under vibration working environment, burner is difficult for loose or dislocation, do not need often to keep in repair, and easy to install and use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A kind of tundish bag tire roaster burner as shown in Figure 1, comprise Threaded Connector Coupling 3 and the interior Threaded Connector Coupling 4 of D25 in φ 50 seamless steel pipes 1, φ 30 seamless steel pipes 2, D40, it is characterized in that: in described D25, Threaded Connector Coupling 4 is welded on one end of φ 30 seamless steel pipes 2 in parallel, in D40, Threaded Connector Coupling 3 is vertically welded in the lateral opening hole place of one end of φ 50 seamless steel pipes 1, described φ 30 seamless steel pipes 2 are welded on φ 50 seamless steel pipe 1 middles, and one end of one end of the interior Threaded Connector Coupling 3 of φ 50 seamless steel pipe 1 welding D40 and the interior Threaded Connector Coupling 4 of φ 30 seamless steel pipes 2 welding D25 is in same direction.
The length that φ 50 seamless steel pipes 1 are stretched out in one end of the described interior Threaded Connector Coupling 4 of φ 30 seamless steel pipe 2 welding D25 is 100mm, and the length that other end φ 30 seamless steel pipes 2 stretch out φ 50 seamless steel pipes 1 is 50mm.
The utlity model has following good effect: this Product Process is simple, length is adjustable, economical and practical.Because burner length is adjustable, burner length can be made according to tundish bag tire height, general burner flame point position is in wrapping tire height 1/3-2/3 place for well, during ventilating coal gas igniting heating, the flame of burner directly enters bag tire lower housing portion, flame has bottom upwards anti-, top and the bottom temperature is even like this, evenly favourable to the baking of working lining, burner flame point is away from bag tire top and bottom steel plate simultaneously, do not destroy the thermal stress of steel plate, and then also can extend the service life of bag tire, burner is to form with seamless Plate Welding, good stability, under vibration working environment, burner is difficult for loose or dislocation, do not need often to keep in repair, and easy to install and use.
