Description

Technical Field

[0001] This utility model relates to the field of hot-rolled strip processing technology, and in particular to a long-distance hot material coating device for slab production. Background Technology

[0002] During the steel loading process on the hot rolling production line, due to limitations in the structure and technical conditions of the steelmaking marking machine, the markings on the incoming slabs from the billet yard are often illegible. Before the slabs are photographed, the heating operation requires repeated manual verification to ensure that the markings on the screen match the actual slabs. If the markings cannot be identified on the screen, the continuous casting personnel must be contacted immediately to repaint the slabs.

[0003] Due to the increased hot charging rate on the rolling line, the temperature of incoming slabs often exceeds 500℃, making it impossible for continuous casting workers to approach the slabs. This poses a risk of burns during the repainting of slab numbers, creating a harsh working environment. Furthermore, when the incoming slab number is unclear and the slab temperature is too high, there is a risk of slab misalignment, posing a hidden danger to subsequent stable rolling. The current solution is to remove the slabs, which affects the steel loading rate and reduces production efficiency.

[0004] To address this problem, an easy-to-operate manual marking device is proposed, which can spray hot material with blurred slab markings from a distance. This not only avoids the possibility of burns during the work process but also reduces the risk of errors in slab marking. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a long-distance hot material coating device for slab production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A long-distance hot material coating device for slab production includes a trumpet-shaped sleeve. An inner heat insulation layer is bonded to the inner wall of the trumpet-shaped sleeve, and an outer heat insulation layer is bonded to the outer wall. The bottom outer wall of the outer heat insulation layer is annularly welded with evenly distributed fixing brackets. A through-slot is formed on one side of the inner wall of the trumpet-shaped sleeve, and a ball rod is installed on one side of the through-slot. A hemispherical shell is provided on the outer wall of the ball rod. A hemispherical cover plate is screwed to the top of the hemispherical shell, and an annular support is welded to the bottom of the hemispherical shell. A steel rod is inserted into the inner wall of the annular support, and a circular top plate is welded to the top outer wall of the steel rod. A positioning groove is formed at the top axis of the circular top plate, and evenly distributed elastic clamping plates are welded around the top perimeter of the circular top plate. A marking pen is inserted between the elastic clamping plates.

[0008] As a further improvement of this utility model: the bottom of each of the three fixed brackets is fixed with a foot brake caster by bolts, and a reinforcing crossbar is welded between adjacent fixed brackets.

[0009] As a further embodiment of this utility model: the inner wall dimensions of the hemispherical shell and the hemispherical cover plate are adapted to the outer wall dimensions of the cue stick, and the hemispherical shell and the hemispherical cover plate form an interference fit with the cue stick.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] A remote hot material coating device for slab production, in this embodiment, such as... Figure 1-4 As shown, the device includes a flared sleeve 1, with an inner heat insulation layer 2 bonded to the inner wall of the flared sleeve 1 and an outer heat insulation layer 3 bonded to the outer wall of the flared sleeve 1. The bottom outer wall of the outer heat insulation layer 3 is annularly welded with equally spaced fixing brackets 4. A through groove 7 is opened through one side of the inner wall of the flared sleeve 1. A ball rod 8 is installed on one side of the inner wall of the through groove 7. The outer wall of the ball rod 8 is provided with a hemispherical shell 9. A hemispherical cover plate 10 is screwed to the top of the hemispherical shell 9. An annular support 11 is welded to the bottom of the hemispherical shell 9. A steel rod 12 is inserted into the inner wall of the annular support 11. A circular top plate 15 is welded to the top outer wall of the steel rod 12. A positioning groove 16 is opened at the top axis of the circular top plate 15. Elastic clamping plates 17 are equally spaced welded around the top of the circular top plate 15. A marking pen 18 is inserted between the elastic clamping plates 17.

[0026] By installing the marking pen 18 at the end of the steel rod 12 and utilizing the long distance of the steel rod 12 in conjunction with the adjustment action of the adjusting pin 14, it is possible to mark the hot material with blurred slab numbers from a distance, thereby improving the working environment of the workers and avoiding the risk of burns.

[0027] The bottom of each of the three fixed brackets 4 is fixed with a foot brake caster 5 by bolts, and a reinforcing crossbar 6 is welded between adjacent fixed brackets 4. The inner wall dimensions of the hemispherical shell 9 and the hemispherical cover plate 10 are adapted to the outer wall dimensions of the cue stick 8, and the hemispherical shell 9 and the hemispherical cover plate 10 form an interference fit with the cue stick 8.
