Abstract
The utility model relates to a triple weir for middle baskets. The utility model is arranged on the approximately parallel inner side of an upper weir plate 3. Steel discharge holes 6 are positioned on the lower parts of both sides of a triple weir plate 5, and are staggered with the steel discharge holes of a lower weir plate 2. The steel discharge hole 6 is split into one to two sections. The utility model forms three flow regions in the middle basket, the fluidal optimization of the middle basket is favorable, the steel provided with impurity is decreased, the cleanliness of the molten steel is improved, and the utility model creates conditions for smelting pure steel and super clean steel, and simultaneously decreases the remained steel quantity of the middle basket. The utility model has the advantages of unique structure, and convenient manufacture, installation and use.
Description
The utility model relates to the container that a kind of casting molten metal is used, particularly the continuous casting internal structure of tundish.
Be mingled with in order to reduce, cleaning molten steel improves steel quality, in the prior art in tundish horizontally set spaced arranged vertical baffle plate, molten steel is refluxed between baffle plate, baffle surface is smooth or coarse, is caught or trapped inclusions by baffle plate.General single baffle plate or the two baffle plate mode of adopting, removal is mingled with effect and is difficult to meet the demands, when particularly smelting clean steel, ultra-clean steel.Indivedual producers also have triple weir plates are set, but there is very big-difference slice posittion, structure with the tundish type.
The purpose of this utility model is that the structure to the triple weirs of tundish is optimized, and can reduce in a large number to be mingled with, and further improves the molten steel degree of purity, and is convenient to make and install and use.
For achieving the above object, the technical solution that the utility model proposes is:
The triple weirs of a kind of tundish, it is installed in the inboard parallel with top slice 3, and its steel discharging hole 6 is positioned at two side lower parts of triple weir plates.
Steel discharging hole 6 staggers with the steel discharging hole position on the following weir plate 2.
Steel discharging hole 6 is for being divided into one to two section.
In conjunction with the accompanying drawings the utility model is done and be described in further detail.
Fig. 1 is the schematic diagram of installation site, the triple weir of tundish of the present utility model.
Fig. 2 is the structural representation on the triple weirs 5 of tundish among Fig. 1.
Referring to Fig. 1,2, in tundish 1, top slice 3 is placed in the middle, and filter baffle plate 4 is installed on the top slice 3, is inserted into the tundish bottom, and its steel discharging hole is positioned in the middle of the base; The outside is following weir plate 2, and its steel discharging hole is positioned in the middle of the base, is inserted into the end; The inboard is triple weirs 5, and steel flow is mingled with by weir plate absorption when weir plate, and changes steel flow to impelling small field trash to assemble by baffle plate.Key of the present utility model is on the triple weirs 5 of top slice installed inside, makes molten steel flow be divided into three zones: between (1) big water-coating port and the triple weir 5, because the impact of big bag beam has formed the speed height, entrainmented serious zone; (2) between triple weirs 5 and the top slice 3, exist a stronger molten steel circulating reflux district; (3) down outside the weir plate 2, flow relatively placidity, of the molten steel of tundish both sides is not more entrainmented generation, in this zone, has flow through long distance near most of molten steel on liquid level top, and this helps inclusion floating and arrives liquid level.
Steel discharging hole 6 on triple weirs 5 is positioned at two side lower parts of weir plate, can be divided into two sections, but guarantees that steel discharging hole is as far as possible little under the prerequisite of remaining molten steel in the emptying tundish, and the steel discharging hole on multiple dam, weir is not on same straight line.
Compared with prior art, the pouring basket triple weir that the utility model obtains can be in the centre Form three flow regions in the bag, be conducive to the optimization of tundish fluidised form, be mingled with in the minimizing steel Content, the cleannes of raising molten steel have been created condition for smelting clean steel and ultra-clean steel; The structure uniqueness, fabrication and installation are easy to use.
