Abstract
The utility model relates to a pouring box filter. Through holes 5 which are arranged in stagger are formed on the surface of a filter 4. The upward slope angle of the through holes 5 is 4 to 25 DEG, and the diameter of the through holes 5 is 10 to 25 mm. Compared with the prior art, the pouring box filter of the utility model has the advantages of unique structure and convenient manufacture, installation and use. The pouring box filter is favorable for the optimization of the flow state of a pouring box. In addition, the utility model can improve the impurity removing capacity of the pouring box and raise the cleanness degree of molten steel. The pouring box filter can adsorb 5.45 to 7.32% of alumina. Thus, filtering efficiency is improved and filtering effect is stable.
Description
The utility model relates to a kind of casting molten metal container, particularly the continuous casting filter 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, this baffle plate can be caught or trapped inclusions.For further improving the molten steel cleannes, the technology of calcium oxide ceramics filter cleaning molten steel has appearred using in recent years, promptly on baffle plate, inlay filter, have clear opening on the filter, when making molten steel pass through filter, calcium oxide and aluminium oxide reaction form low-melting compound, reach the purpose of nonmetal inclusion in the absorption molten steel.This through hole is generally the identical lateral aperture of diameter in the prior art, and the effect of its purify hot metal is limited.
The purpose of this utility model is that the structure to middle IP filter is optimized, and can further improve the molten steel filter effect, 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 obtains of the utility model is:
A kind of tundish filter has the hole 5 of perforation on the filter 4, through hole 5 is acclivitous along the steel flow path direction.
Superposed through-hole diameter is less than the through-hole diameter that is positioned at the bottom.
Through hole 5 acclivitous angle [alpha] are 4～25 °.
The diameter of through hole 5 is 10～25 millimeters.
Through hole 5 is that checkerboard is staggered on the surface of filter.
In conjunction with the accompanying drawings embodiment of the present utility model is done and be described in further detail.
Fig. 1 is the schematic diagram of the utility model tundish filter installation site.
Fig. 2 is the A-A cutaway view among Fig. 1.
Fig. 3 is the partial enlarged drawing of through hole 6 on Fig. 2 middle filtrator.
Fig. 4 is the stereogram of the utility model tundish filter.
Referring to Fig. 1～4, the calcium oxide ceramics filter 4 of present embodiment is the tetragonal pyramid bench-type, can build by laying bricks or stones, be installed on the top slice 2 easily, build by laying bricks or stones in tundish 1 with weir plate then, top slice 2 outsides are following weir plate 3, through hole on the filter is staggered checkerboard type and distributes on the surface of frustum, have 4 filters, and top through-hole diameter is less than following.Simultaneously; the through hole 5 of ceramic filter has the inclined angle alpha (about 5 °) that makes progress along the steel flow path direction; to prolong molten steel time of staying in tundish; make molten steel have the speed that flows to the surface; flowing to covering protection slag-molten steel has a lower speed at the interface, and Shang Fu field trash is just caught by the covering slag of tundish like this, can increase the chance that slag absorbs field trash; can separate to greatest extent and remove, improve the degree of purity of molten steel.
Compared with prior art, the available tundish filter structure of the utility model is only The spy, making, installation, easy to use are conducive to the optimization of tundish fluidised form, can improve Except the ability of field trash, improve the cleannes of molten steel, the adsorbable aluminium oxide of this filter 5.45～7.32%, make and filter the benefit raising, filter effect is stable.
