Pouring structure for tank edge of molten steel tank

Abstract

The invention discloses a pouring structure for the tank edge of a molten steel tank. The pouring structure comprises a steel structure layer on the outermost layer, a castable permanent layer, anchoring parts, an anchoring rib plate, a tank edge castable layer and a working layer corundum brick. The anchoring parts, the anchoring rib plate and the tank edge castable layer are located in the middle, and the working layer corundum brick is located on the innermost side. The anchoring parts are of anchoring plate platy structures, the whole circle of anchoring rib plate is welded to the portion,in the middle of the tank edge, of the steel structure layer, the anchoring rib plate, anchoring plates and the steel structure layer are welded into a whole, the welding amount and the welding strength are greatly improved, and damage to the anchoring parts in the using and detaching processes is effectively reduced. The V type anchoring parts are additionally welded to the anchoring plates, thedensity of the anchoring parts is improved, and the anchoring effect on castable is enhanced. The structural design is novel, by improving the structures of the anchoring parts, the welding amount and the welding strength are greatly improved, damage to the anchoring parts in the using and detaching processes is effectively reduced, the strength of the castable on the tank edge is enhanced, and the phenomenon of steel permeation caused by a large circular seam of the tank wall is reduced.

Description

【Technical field】 [0001] The invention relates to the field of building and laying of molten steel tanks for steelmaking, in particular to a pouring structure along the molten steel tank. 【Background technique】 [0002] Existing steel ladle tank rim structures are, for example figure 1 As shown, the tank edge structure of the original molten steel tank includes steel structure layer 01, tank edge plate 02, castable permanent layer 03, D-shaped anchor piece 04, tank edge castable layer 05 and corundum brick working layer 06, as shown in figure 2 As shown, the former steel ladle tank includes a steel structure layer 07, a ding-shaped anchor 08 and a corundum brick working layer 09 along the anchor. The defective along the structure of this molten steel tank is that the anchor is welded in the middle, and the anchor is nail-shaped, and the welding amount of the welded part is small, and the firmness is insufficient. [0003] During the operation and use of the molten steel t...

AI Technical Summary

Problems solved by technology

[0005] The welding amount of the anchorage parts along the tank is small, and the firmness is insufficient. The pouring material along the tank is severely damaged during use, and the working layer of the molten steel tank cannot be compacted, resulting in a large circular seam in the working layer, resulting in the phenomenon of steel seepage in the circular seam and back seam

During the maintenance and removal process of the tank, the anchors fall off, and the anchors must be welded for each intermediate maintenance, which is cumbersome and time-consuming

The pouring material along the tank is very easy to collapse and fall off during the anchoring process, resulting in waste of refractory materials and unplanned off-line, affecting the normal operation of the molten steel tank
