Abstract
The utility model discloses a filter residue board is described to bars of guaranteeing serviceability in middle of continuous casting, which comprises a plate body, the plate body is trapezoidally, the interval is setting up two lugs on the plate body top surface, set up the molten steel ostium by last to the average cloth interval of launching on one side face of plate body, set up molten steel outflow hole by last to the average cloth interval of launching on the opposite side face of plate body, molten steel ostium and molten steel outflow kong jun are rectangle, the position of molten steel ostium is higher than the position in molten steel outflow hole, passageway through vertical layout between molten steel ostium and the molten steel outflow hole is linked together, the width of molten steel ostium is 40mm, the width in molten steel outflow hole is 20mm. But the aluminium oxide inclusion in the molten steel is got rid of in the existing water conservancy diversion of this bars form filter residue board effect effective filtration again, improves the cleanliness factor of molten steel, solves the technological problem of mouth of a river dross.
Description
Technical field
The utility model relates to a kind of continuous casting production palisade filter residue plate.
Background technology
Continuous casting production is the bridge and the cistern that connect large bag and crystallizer.The molten steel of large bag injects tundish by large bag long nozzle, then injects crystallizer through tundish.The flow velocity that large water-coating port injects tundish is 3.2m/s, belongs to high turbulence.Tundish turbulent flow can cause much harm, and such as, bag liquid fluctuating is large, slag and be involved in gas, the time that the short field trash of molten steel flow process does not float.For solving the turbulent flow of tundish, common way arranges baffle plate in tundish, baffle plate opened some holes.After the turbulent flow in the tundish beam district hole on slag trap flows out, make turbulent flow become laminar flow, eliminate the harm of tundish turbulent flow.Such baffle plate only has the effect of current stabilization and water conservancy diversion, effectively can not remove the field trash in molten steel.The particularly deoxidation products of Al2O3 and so on, as can not be effectively removed, the easy dross of water-coating port in during cast.
Summary of the invention
The purpose of this utility model is to provide a kind of continuous casting production palisade filter residue plate, and the existing guide functions of this palisade filter residue plate effectively can filter again the aluminate removed in molten steel, improves the cleanliness factor of molten steel, solves the technical barrier of nozzle clogging.
The purpose of this utility model realizes like this, a kind of continuous casting production palisade filter residue plate, comprise plate body, plate body is inverted trapezoidal, on plate body end face, interval arranges two hangers, on the side plate face of plate body, the uniform interval of level arranges steel flow hand-hole from top to bottom, in another lateral plates of plate body, level uniform interval arranges steel flow and portals from top to bottom, steel flow hand-hole and steel flow are portalled and are all rectangle, the position portalled higher than steel flow in the position of steel flow hand-hole, be connected by the vertical passage arranged between steel flow hand-hole portals with steel flow, the width of steel flow hand-hole is 40mm, the width that steel flow is portalled is 20mm.
During use, large Baogang water is injected near cast central point through large bag long nozzle.Molten steel in tundish enters middle water containing opening district by pouring into a mould impact zone through palisade filter residue plate, and steel stream now becomes laminar condition from the turbulence state of impact zone.When molten steel is by filter residue plate, be introduced into the steel flow hand-hole of top, then sink, portalling via steel flow enters into the mouth of a river district of bag.Because the proportion of the field trash in molten steel is lighter than molten steel far away, when the field trash in molten steel is via wide grid, floating, to assemble, be attached on steel flow hand-hole upper surface.The field trash of Al2O3 causing nozzle clogging and so on easy especially agglomeration in molten steel in molten steel, and be easily attached on the surface of refractory material.Therefore, the filtration result of palisade filter residue plate to Al2O3 is particularly evident.The existing guide functions of this palisade filter residue plate effectively can filter again the aluminate removed in molten steel, improves the cleanliness factor of molten steel, solves the technical barrier of nozzle clogging.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is side elevational cross-section structural representation of the present utility model.
Detailed description of the invention
A kind of continuous casting production palisade filter residue plate, as Fig. 1, shown in Fig. 2, comprise plate body 2, plate body 2 is in inverted trapezoidal, on plate body 2 end face, interval arranges two hangers 1, on the side plate face of plate body 2, the uniform interval of level arranges steel flow hand-hole 3 from top to bottom, in another lateral plates of plate body, level uniform interval arranges steel flow and portals 4 from top to bottom, steel flow hand-hole 3 and steel flow are portalled and 4 to be all rectangle, the position of steel flow hand-hole 3 portal higher than steel flow 4 position, steel flow hand-hole 3 and steel flow are portalled between 4 and are connected by the passage vertically arranged, the width of steel flow hand-hole 3 is 40mm, steel flow portal 4 width be 20mm.
Claims (1)
