Embodiment Construction

[0038] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0039] Such as figure 1 As shown, a hot billet corner crack online cleaning device according to the present invention is arranged between the segment of the continuous casting machine and the torch cutter, and includes inner arc cleaning guns 1, 2, outer arc cleaning guns 3, 4, Side slag treatment water guns 5, 6, inner arc water curtains 7, 8; outer arc water curtains 13; clamps 9, 10, trolleys 11, 12 and cart 14; cart 14 spans above the slab conveying roller table, The two trolleys 11 and 12 are respectively arranged on both sides of the cart 14 and can reciprocate along the direction perpendicular to the conveying direction of the slab 15; Billet 15, clamps 9, 10 clamp the billet 15 and drive the cart 14 to follow the billet 15; 2 sets of inner arc cleaning guns 1, 2, 2 sets of outer arc cleaning guns 3, 4 and 2 sets of side slag treatment On...

Abstract

The invention relates to an online cleaning device and method for cracks at the corners of hot billets. An online cleaning device for cracks at the corners of hot billets is added between the sector section of the continuous casting machine and the torch cutter; after preheating preparation, preheating positioning, and preheating , cleaning, flue gas capture and slag treatment process, it can clean the corners of the four corners of the slab at the same time to make a smooth transition, effectively avoiding the shortcomings of too large "corner re-cleaning" area and high loss of steel materials; through automatic The positioning meets the cleaning requirements of billets with different cross-section sizes, the burner can be adjusted to meet the requirements of different cleaning depths, and the energy and medium parameters can be adjusted to adapt to the change of casting speed; and it can realize the "one-button" operation to start the automatic cleaning program, and the online cleaning does not affect 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...
