Description
Technical field
Casting field is the utility model is related to, 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.
Utility model content
The utility model is in view of the shortcomings of the prior art, there is provided one kind can effectively be filtered to scum silica frost, and be reduced
Impact of the molten steel to screen pack, improve the purification of molten steel filter of the degree of purity of molten steel.
To realize the utility model purpose, there is provided following technical scheme：A kind of purification of molten steel filter, including fire resisting
Brick rectangular 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
Three pieces of dividing plates are disposed with casing from left to right, casing is separated into four chambers, first partition bottom and casing successively
Bottom end seal is connected, and top forms overfall with casing top interval, and second partition top is connected with casing top, bottom and case
Body bottom, which is arranged at intervals, forms communication port, is provided with the first screen pack in communication port, is provided between first partition and second partition
Ceramic filtering body, ceramic filter body section to be up big and down small trapezoidal, ceramic filtering body both sides and first partition, second partition it
Between gap form sluice way, the 3rd dividing plate bottom be connected with casing bottom, and top and casing top composition overfall, molten steel enter
Mouth is located at first chamber, and molten steel outlet is located at the 4th chamber, 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 5 × 5mm, it is 4 × 4mm most to descend aperture.
Preferably, the second screen pack is ceramic material.
The utility model beneficial effect：The utility model sets Multi-channel filtering, and substantially reduces flow velocity by overflow, subtracts
Few molten steel impacts and sets ceramic filtering body to carry out initial absorption and filtering to molten steel scum silica frost, greatly improves the purity of molten steel, carries
The quality of high casting.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
