Description
Technical field
The present invention relates to metallurgical technology field, particularly relate to the heat accumulating type vacuum chamber baking system of a kind of suitable for reading and lower mouth baking from vacuum chamber.
Background technology
In the last few years, along with terminal user is more and more higher to the requirement of steel product quality, the ratio of molten steel vacuum refining was more and more higher. Vacuum metling has good kinetic character, and metallurgical effect is given prominence to, and becomes basically universal in Ge great steel mill in recent years.
High Temperature Air Combustion, also known as regenerative combustion technology, can greatly improve the organic efficiency of fuel availability and fume afterheat, and energy consumption is reduced greatly, use commonplace in steel mill at present. CN200810048112.9 discloses a kind of single heat storage type ladle baking facility.
In prior art, vacuum chamber baking adopts baking gun or non-heat-storage ladle roaster to toast usually. There are no the report of RH heat-storage ladle roaster. Compared with the metallurgical tank such as ladle, Tie Bao, tundish, vacuum chamber total length is longer, for the vacuum chamber that 11m is big like this, needs to ensure that the vacuum chamber upper and lower storing temperature of resistance to material is evenly consistent simultaneously, adopts heat-accumulating baking device to need to overcome this difficult point.
Summary of the invention
Technical problem to be solved by this invention is just technical deficiency to above-mentioned existence, there is provided a kind of for large-scale vacuum room, upper and lower storing temperature can be realized consistent, improve cured effect, improve baking quality, and the heat accumulating type vacuum chamber baking system of the suitable for reading and lower mouth from vacuum chamber of save energy baking.
The technical solution adopted for the present invention to solve the technical problems is:
From vacuum chamber, a heat accumulating type vacuum chamber baking system for suitable for reading and lower mouth baking, includes vacuum chamber body, it is characterised in that: the upper and lower two ends of described vacuum chamber body, are provided with baking system; Vacuum chamber body upper end is provided with baking lid, in baking lid, multiple regenerator is installed, heat storage is installed in regenerator, regenerator top is connected with air-blast system by the first commutation control valve, exhausting system and combustion gas, regenerator bottom is connected heat-accumulating burner, and heat-accumulating burner extends in vacuum chamber body; The lower end of described vacuum chamber body is provided with vacuum chamber tubular stinger, vacuum chamber tubular stinger is outside equipped with frame, multiple regenerator is installed in frame, heat storage is installed in regenerator, regenerator bottom is connected with air-blast system by the 2nd commutation control valve, exhausting system and combustion gas, regenerator top is connected heat-accumulating burner, and heat-accumulating burner extends in vacuum chamber body.
In such scheme, for being tightly connected between described baking lid and vacuum chamber body, and junction is provided with insulating refractory.
In such scheme, for being tightly connected between described frame and vacuum chamber body, and junction is provided with insulating refractory.
In such scheme, the heat-accumulating burner number that the regenerator in described frame connects is identical with the number of valve tube tubular stinger, and each heat-accumulating burner correspondence is through a valve tube tubular stinger.
In such scheme, the first described commutation control valve and the 2nd commutation control valve are the setting that works at times, and both intersections open and close in turn, it is achieved vacuum chamber body top and the bottom Baking out in turn.
The innovative point of the present invention is:
1, upper and lower opening toasts simultaneously, is applicable to the large-tonnage vacuum chamber of length more than 11m.
2, adopting accumulation of heat nozzle to replace conventional spout, utilize regenerator to be heated by air, utilize regenerative combustion technology, first heat air, then toasts vacuum chamber.
3, installing baking nozzle at lower vacuum tubular stinger, it is possible to utilize the principle that hot gas rises naturally, bottom heating can toast whole vacuum chamber.
4, when upper and lower ends is different, baking, works at times, it is possible to when identical amount of consumed gas, plays better cured effect, effectively saved the energy.
The useful effect of the present invention: upper and lower storing temperature can be realized consistent, improve cured effect, it is to increase baking quality, and shorten drying and the baking time of vacuum chamber, improve working efficiency, also extend the work-ing life of vacuum chamber, play the effect of energy-saving and emission-reduction simultaneously.
