Description
Technical field
The present invention relates to casting field, more particularly to purification of molten steel filter is used in casting during casting.
Background technology
The cast of high temperature alloy is typically all first poured into refractory brick using molten steel, and one layer of filtering is laid on refractory brick
Net, molten steel are diverted in ingot mould by the screen pack on refractory brick.Due to when molten steel passes through refractory brick in casting process, in molten steel
Active element can be reacted with refractory brick, increase the scum silica frost in molten steel, in addition molten steel in casting process with temperature
Reduce, the field trash being dissolved in molten steel can separate out from steel, cause scum silica frost in molten steel to increase.Using common pouring type,
Screen pack riding position is forward so that molten steel can still be polluted by refractory brick after filtering, the filtering passed through additionally, due to molten steel
Net negligible amounts, usually 1-2 levels screen pack, the scum silica frost of molten steel surface can not fully float, part scum silica frost flows into aluminium alloy
Into ingot mould, the degree of purity of alloy pig is caused to decline.
Prior art typically uses foam ceramic filter, easily causes blocking during long-term use of, scum silica frost is difficult to clean off, and is had
It is to be modified.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides one kind can effectively be filtered to scum silica frost, and reduce molten steel
Impact to screen pack, improve the purification of molten steel filter of the degree of purity of molten steel.
To realize the object of the invention, there is provided following technical scheme：A kind of purification of molten steel filter, including refractory brick length
Square box, casing, which keeps left, holds top surface to offer molten steel import, and end bottom surface of keeping right offers molten steel outlet, it is characterised in that casing
Three pieces of dividing plates are inside disposed with from left to right, and casing is separated into four chambers, first partition bottom and casing bottom successively
It is tightly connected, top forms overfall with casing top interval, and second partition top is connected with casing top, bottom and casing bottom
End, which is arranged at intervals, forms communication port, is provided with the first screen pack in communication port, ceramics are provided between first partition and second partition
Filtering body, ceramic filter body section is up big and down small trapezoidal, between ceramic filtering body both sides and first partition, second partition
Gap forms sluice way, and the 3rd dividing plate bottom is connected with casing bottom, and top forms overfall, molten steel import position with casing top
In first chamber, molten steel outlet is located at the 4th chamber, and the second screen pack is provided with molten steel outlet.
Preferably, the second screen pack is up big and down small trapezoidal plate body including section, aperture is uniformly offered on plate body
The square opening tapered into.
Preferably, the 4th chamber top is provided with blast pipe.
Preferably, square opening maximum diameter of hole is 5X5mm, it is 4X4mm most to descend aperture.
Preferably, the second screen pack is ceramic material.
Beneficial effect of the present invention：The present invention sets Multi-channel filtering, and substantially reduces flow velocity by overflow, reduces molten steel punching
Hit and set ceramic filtering body to carry out initial absorption and filtering to molten steel scum silica frost, greatly improve the purity of molten steel, improve casting
Quality.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
