Embodiment Construction

[0044] 1) Invention No. 1 and Invention No. 5

[0045] An example of an embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is an explanatory diagram for explaining an example of an embodiment of the present invention, that is, a method of heating a ladle, Figure 4 It is an explanatory diagram for explaining the method of rapidly heating the ladle on the molten steel trolley when it is on standby in the tapping area with a regenerative burner, Figure 5 yes Figure 4 top view of Image 6 It is a schematic diagram for explaining the operation of the regenerative burner.

[0046] (1) Rapid heating method

[0047] Referring to Fig. 1, the ladle 1 used in converter operation is moved to the slag discharge area B2 by a crane 2 after continuous casting, and the ladle 1 is tilted in the slag discharge area B2 to discharge the steel slag remaining inside. Then, move to the maintenance inspection area (not shown), and after cleaning ...

Abstract

A method of heating the ladle before receiving molten steel. After continuous casting and slag removal, the ladle is placed on the molten steel trolley, and then transported by the molten steel trolley to the tapping area of ​​the converter, and then placed on the molten steel trolley 1. Stand by in the tapping area for a specified time to form a standby state. After the standby, the molten steel flowing out from the converter is immediately received, and the ladle is heated before receiving the molten steel. In the tapping area of ​​the converter, it is in a standby state. The ladle is heated rapidly within a specified time. This rapid heating is carried out by means of a regenerative burner installed on the ladle cover covering the upper opening of the ladle.

Description

technical field [0001] The invention relates to a method of heating a ladle used in the operation of a converter for conveying molten steel of the converter. Background technique [0002] 1) Referring to Figure 3, the ladle 1 used in converter operation is moved to the slag discharge area B1 by a crane 2 after continuous casting, and the ladle 1 is tilted in the slag discharge area B1, so that the slag remaining inside discharge. Then, it moves to a maintenance inspection area (not shown), and after the slide nozzle is cleaned or replaced in this maintenance inspection area, it moves to a preheating area C1. In this preheating zone C1, the ladle 1 is heated by the burner 4 etc. in order to dry the ladle 1 and to compensate the temperature drop of the molten steel received from the converter 3. [0003] Next, the ladle 1 is placed on the molten steel trolley 5 by a crane 2 or the like, and transported to the tapping area D1 of the converter 3 in this ...
