Abstract
A kind of trapezoidal bottom of steel ladle structure, comprise high-order district, low level district, two bottom blowing gas ports, a sprue gate, low level district refractory brick height 260mm, it is characterized in that: be also provided with meta district, meta district is linked up by rectangle region, oblique angle district and forms, rectangle region is in fourth quadrant, one border is on 0 degree of line, gap is possessed at another border and sprue gate, oblique angle district prolongs alignment both sides centered by the angular bisector of third quadrant expansion two S shape oblique angle lines, and the surface area in oblique angle district is 1-1.1 times of rectangle region surface area; Surround in meta district the 3rd, the bottom wall area of fourth quadrant is low level district, and the rest interval of diapire is high-order district; Meta district is higher than low level district 40mm, and high-order district is higher than meta district 50mm.Advantage is: the meta district of the transition that expands high-order district, reduces low level district, sets up, makes molten steel enter sprue gate comparatively concentrated, and strengthen position drop simultaneously and promote diapire residual molten steel amount of flow, reduce molten steel residual quantity, every Bao Cike multithread goes out 0.2 ton, molten steel.
Description
Technical field
The utility model relates to ladle structure, particularly a kind of trapezoidal bottom of steel ladle structure.
Background technology
After pneumatic steelmaking, molten steel injects large bag, then transfers rear centering by driving and wrap and inject, and middle bag injects slab mould and crystallizes into base.Be fire-resistant inwall, diapire in the hangers that large pack arrangement comprises inclusion, inclusion outer wall is arranged, inclusion, diapire is provided with two bottom blowing gas ports, a sprue gate.Inwall, diapire are all built into by refractory brick, and first and second quadrant of diapire is respectively equipped with bottom blowing gas port, and fourth quadrant is provided with sprue gate.Be middle section in bag between two bottom blowing gas ports, a sprue gate, middle section is built into the refractory brick that 280mm is high, and the refractory brick that the outer peripheral areas 260mm of middle section is high is built into, and forms central high district and periphery low level district.Its object is to make central high district molten steel can be discharged to periphery low level district completely, because the mobility of molten steel is more very different than light water, if diapire is whole contour as conventional vessel, then after pour steel, diapire can deposition fraction steel flow not walked, so diapire sets up high-low position district.Diapire low level block reservation certain altitude molten steel to be controlled, bag during the slag preventing molten steel upper surface from floating flows into during pour steel.We find in operation, though central high district does not have molten steel to deposit, but periphery low level district still deposits many molten steel, and low level district area to be greater than high-order district too much, this is irrational, especially the back zone deposition of two bottom blowing gas ports is comparatively large, and deposition can form cold steel bulk, outwells wastage also not little during cleaning.
Summary of the invention
The utility model object, for overcoming above-mentioned defect, provides a kind of trapezoidal bottom of steel ladle structure.
The utility model scheme is: comprise high-order district, low level district, two bottom blowing gas ports, a sprue gate, low level district refractory brick height 260mm, it is characterized in that: be also provided with meta district, meta district is linked up by rectangle region, oblique angle district and forms, rectangle region is in fourth quadrant, one border is on 0 degree of line, gap is possessed at another border and sprue gate, oblique angle district prolongs alignment both sides centered by the angular bisector of third quadrant expansion two S shape oblique angle lines, and the surface area in oblique angle district is 1-1.1 times of rectangle region surface area; Surround in meta district the 3rd, the bottom wall area of fourth quadrant is low level district, and all the other regions of diapire are high-order district; Meta district is higher than low level district 40mm, and high-order district is higher than meta district 50mm.
The utility model has the advantage of: two Bottom Blowing hypostomal areas are increased, expand high-order district, reduce low level district, set up the meta district of transition, molten steel is made to enter sprue gate comparatively concentrated, strengthen the position discrepancy in elevation simultaneously and promote diapire residual molten steel flowing velocity, amount of flow, every Bao Cike multithread goes out 0.2 ton, molten steel.

detailed description of the invention
The utility model structure comprises high-order district, low level district, two bottom blowing gas ports, 3, sprue gate 4, low level district refractory brick height 260mm, it is characterized in that: be also provided with meta district 6, meta district 6 is linked up by rectangle region, oblique angle district and forms, rectangle region is in fourth quadrant, one border is on 0 degree of line, gap is possessed at another border and sprue gate 4, oblique angle district prolongs alignment both sides centered by the angular bisector of third quadrant expansion two S shape oblique angle lines, and the surface area in oblique angle district is 1-1.1 times of rectangle region surface area; Surround in meta district 6 the 3rd, the bottom wall area of fourth quadrant is low level district 7, and all the other regions of diapire are high-order district 5; Meta district 6 is higher than low level district 40mm, and high-order district 5 is higher than meta district 50mm.
High-order district 5, meta district 6, low level district drop strengthen, and are beneficial to residual molten steel flowing, strengthen diapire residual flow amount.
Low level district 7 area reduces interface near sprue gate 4, more much smaller than former low level district, and high-order district 7 enlarged areas is more much bigger than former high-order district, and meta district 6 is as overcurrent district.In inclusion 1, be placed in the low level district 7 of the technology of the present invention if remain gauge with former low level district molten steel, then the molten steel water surface is much higher, and hydraulic pressure usury is in MOLTEN STEEL FLOW.Diapire low level district 7 retains same certain altitude anti-slag stream molten steel, reduces molten steel residual quantity, the many discharges of every Bao Cike 0.2 ton of molten steel, and the molten steel amount of many bags time is then considerable, improves output.
