Detailed Description

The technical solutions in the present embodiments will be clearly and completely described below with reference to the accompanying drawings in the present embodiments, which, however, should not be construed as limiting the present invention to specific embodiments, but are for explanation and understanding only:

as shown in fig. 1, fig. 2 and fig. 3, this embodiment provides a well package immersion nozzle off-line bakes out stove, immersion nozzle 5's inner chamber and the inner chamber intercommunication of well package upper nozzle, bake out the stove set up in well package lower nozzle department, bake out the stove and include furnace body 2, several strengthening rib 3 is installed to 2 inner walls of furnace body, 2 intussuseption of furnace body are filled with heat preservation 4, and heat preservation 4 covers strengthening rib 3 avoids strengthening rib 3 to expose and causes the damage to

immersion nozzle

5, 4 processing of heat preservation have the chamber of toasting that holds immersion nozzle 5.

Heat preservation 4 toasts the in-process at immersion nozzle 5 and plays thermal-insulated heat retaining effect, 3 specifically can form by the alloy preparation that has higher intensity and good heat resistance, 3 effect that the strengthening rib was equipped with the skeleton support in furnace body 2, promote the holding power of furnace body 2 to heat preservation 4, maintain heat preservation 4's shape, reduce the deformation of heat preservation 4 in the long-time use, the heat preservation effect that makes heat preservation 4 of different positions can not have great drop, help promoting furnace body 2's heat preservation effect, can promote the life of baking oven, and when processing preparation baking oven, strengthening rib 3 helps the shaping of heat preservation 4.

The detailed structure of the furnace body 2 is as follows:

the reinforcing ribs 3 are uniformly distributed along the inner wall of the furnace body 2 at intervals, so that the reinforcing ribs 3 have supporting force for the heat-insulating layers 4 at all positions, and the whole furnace body 2 is firm and stable.

The strengthening rib 3 includes first muscle section and second muscle section, the one end and the 2 inner wall fixed connection of furnace body of first muscle section, the other end of first muscle section to 2 inside extensions of furnace body play the effect of skeleton, first muscle section perpendicular to 2 inner walls of furnace body, when 2 lateral walls of furnace body are vertical promptly, 3 levels of strengthening rib can promote strengthening rib 3 to 4 holding power on the heat preservation, the one end and the first muscle section fixed connection of second muscle section, the other end of second muscle section is kept away from to the back the direction of first muscle section extends, second muscle section is hugged closely and is fixed on 2 inner walls of furnace body, and second muscle section is followed promptly 2 direction of height settings of furnace body, second muscle section one end and first muscle section fixed connection, first muscle section and second muscle section can adopt integrated into one piece to make to strengthen the supporting effect of strengthening rib 3.

The heat-insulating layer 4 is made of dry materials, the dry materials are filled in the furnace body 2, and the dry materials are resistant to corrosion of molten steel and molten slag in the using process, long in service life, not easy to sinter and convenient to remove slag. When the baking furnace is processed, the reinforcing ribs 3 have a better supporting effect on unformed dry materials, the solidification forming of the dry materials is facilitated, and after the dry materials are solidified, the reinforcing ribs 3 also have a supporting effect.

An inlet and a notch are arranged on the furnace body 2, a top plate is arranged at one end of the furnace body 2, and the inlet is arranged on the top plate; the other end of the furnace body 2 is provided with a bottom plate, the opening is arranged on the side wall of the furnace body 2, the opening extends from the inlet to the direction of the bottom plate, the baking cavity is communicated with the opening, and the submerged nozzle 5 can smoothly enter the baking cavity.

2 outer walls of furnace body are equipped with a pair of lug 1 relatively, and is a pair of lug 1 is located the both sides of entry, lug 1 conveniently remove furnace body 2 as adapting unit when furnace body 2 hoists, and lug 1 is located the top of furnace body 2, makes furnace body 2 when removing, and its focus is located the below of hoist and mount connecting piece, is favorable to improving the stability when furnace body 2 removes, further improves the security in the workshop when furnace body 2 removes.

The furnace body 2 is cubic, the outer wall of the furnace body 2 is hinged with a furnace door (not shown in the attached drawing) for sealing the upper part of the notch, and the furnace body 2 is cubic, so that the side wall of the furnace body is smooth, the furnace door has good sealing performance on the upper part of the furnace body 2, heat loss can be reduced, when the furnace body is used, the temperature in the baking cavity is quickly raised, the heat preservation effect is good, and further energy can be saved.

The entry with the opening all processes for the rectangle, the entry with the width of opening all is less than the diameter of 5 mouth of a river supports of immersion nozzle, the length of opening is greater than the length of immersion nozzle 5, the taking out of immersion nozzle 5 of being convenient for makes have the clearance between immersion nozzle 5 and heat preservation 4 and the bottom plate, is favorable to the heat transfer, promotes the effect of toasting.
