Problems solved by technology

[0008] The purpose of the present invention is to provide an energy-saving tundish in order to overcome the defects of the prior art that there are few roasting nozzles, large consumption of baking gas, rapid temperature drop of exposed roasting, and uneven baking temperature of the nozzles. Submerged nozzle baking oven and baking method, the baking oven can perform uniform and effective baking on multiple nozzles at the same time, and the required baking gas consumption is greatly reduced

Embodiment 1

[0139] An energy-saving medium-package immersion nozzle oven, such as figure 1 shown, it is baked as follows:

[0140] ①It is necessary to pass the submerged nozzle 12 of the middle bag to be baked through the nozzle placement hole 102 on the box cover 101, respectively put the nozzle 12 into the box 1, and keep the nozzle 12 vertical. At this time, the nozzle bowl 1201 will be stuck in The nozzle is placed above the hole 102 . The number of nozzle placement holes 102 is 6, and the number of nozzle placement holes 12 is also 6; the shortest distance between two adjacent nozzle placement holes 102 is 140mm, and the shortest distance between the nozzle placement holes 102 and the burner is 120mm, the hole diameter of the nozzle placement hole is 115mm. The inner cavity size of the box body 1 is 1200mm×1200mm×1200mm.

[0141] ②Confirm the ignition status, if there is no fire, press the ignition switch button on the control device 11 to confirm that the burner 3 is on fire.

...

Embodiment 2

[0149] According to Example 1, the difference is that the shortest distance between two adjacent nozzle placement holes 102 is 170 mm.

[0150] The preheating time of this embodiment is 20min, and the rapid baking time is 38min.

Embodiment 3

[0152] According to Example 1, the difference is that the size of the inner cavity of the box body 1 is 1600mm×1600mm×1600mm.

[0153] The preheating time of this embodiment is 26min, and the rapid baking time is 46min.

Abstract

The invention belongs to the technical field of tundish submersed nozzle baking, and particularly relates to an energy-saving tundish submersed nozzle baking oven and a baking method.The baking oven comprises an oven body, an inner cavity of the oven body is cylindrical, the oven body is provided with an oven cover, and a plurality of nozzle containing holes distributed at intervals in the circumferential direction are formed in the oven cover; the liftable water gap heat preservation cover is connected to the box body in a liftable mode and covers the upper portion of the box cover to seal the box body; the burner is located at the bottom in the box body and located below the circle center of the circumference where the water gap containing holes are located. And the gas supply assembly extends into the box body and is connected with the burner. The baking oven is uniform in baking temperature, fast in temperature rise, short in baking time, good in heat preservation effect and low in gas consumption.

Description

technical field [0001] The invention belongs to the technical field of middle-package immersion nozzle baking, in particular to an energy-saving middle-package immersion nozzle baking oven and a baking method. Background technique [0002] Before the continuous casting machine starts pouring, it is necessary to bake the tundish immersion nozzle to a certain temperature. The baking operation of the tundish immersion nozzle is a very important part in the continuous casting production. When the pouring is started, when the pouring steel flows through the inside of the nozzle, it is easy to form cold steel, resulting in the failure of the pouring. When the nozzle baking temperature is too high, the service life of the nozzle will be reduced. [0003] At this stage, the offline baking method of the immersion nozzle in the middle package is to use an offline baker to bake. The main disadvantages of this roaster are: [0004] 1. An offline roaster can only roast a single nozzle...
