Abstract

The invention relates to an online hot blank corner crack clearing device and method. An online hot blank corner crack clearing device is additionally arranged between the sector section of a continuous casting machine and a torch cutter. Through the process of preheating preparation, preheating locating, preheating, clearing, smoke collection and slag treatment, clearing can be conducted on the corner portions on the four corners of a cast blank at the same time, the corner portions can be in smooth transition, and the defects that a corner re-clearing area is excessively large, and the lossof a steel material is high are effectively overcome; through automatic locating, the requirement for clearing cast blanks of different section dimensions is met, through adjustment of a burner, the requirement for different clearing depths is met, and through adjustment of energy medium parameters, the online hot blank corner crack clearing device is adapted to the change of a drawing speed; theautomatic clearing procedure can be started through one-button type operation, and online clearing does not influence the continuous casting production rhythm.

Description

technical field [0001] The invention relates to the technical field of continuous casting production, in particular to an on-line cleaning device and method for cracks at corners of hot billets, which are suitable for online cleaning of cracks at four corners of hot billets. Background technique [0002] Restricted by the current level of continuous casting technology, the slabs produced by continuous casting machines, such as pipeline steel, usually have cracks at the corners, and the products cannot meet the requirements of hot delivery. It restricts production efficiency, loses a lot of heat energy and increases carbon emissions. [0003] The Chinese patent with the application number 201410816308.3 discloses "A Device and Method for Cleaning Bad Corners of Slabs". The cleaning device is installed between the outlet of the second cold room of the continuous casting machine and the torch cutter, including nozzles, burners, and media boxes. , traversing equipment, synchron...
