Abstract
The utility model provides a pouring basket absorber, and the pouring basket absorber comprises a plurality of strip columns. The strip columns arranged in staggered way, the space length is 10 to 20 mm, the diameter is 30 to 70 mm. The structure of the absorber is simple, the installation is convenient, the active surface area of the structure of the absorber the absorber and liquid steel contact is large, the sundries absorbing capacity is high, the utility model can reduce the content of oxide by 30 percent to 50 percent in the steel, and reduce the large granule by more than 50 percent in the steel.
Description
Technical field
The utility model relates to a kind of casting molten metal container, relates in particular to the absorber of continuous casting tundish.
Background technology
Tundish is being undertaken considerable role in continuous casting production, except that the effect of playing a buffer, also play and distribute molten steel and remove the effect of field trash in the molten steel in the tundish in crystallizer.Directly have influence on the quality of strand by the steel quality of tundish submersed nozzle inflow crystallizer.Along with more and more higher to the requirement of steel products quality, and the success aspect tundish metallurgy, people can not be used tundish again as a simple container, but striven in tundish, further removing field trash, and prevented the secondary pollution of molten steel.The molten steel field trash is mainly derived from the secondary oxidation thing of the deoxidation products of converter molten steel, big cinder inclusion, middle cinder inclusion, molten steel etc. in the tundish.Above-mentioned field trash to be removed in tundish as far as possible in the actual production.
Tundish has played very important effect as the main carrier in the metallurgical process to removing harmful field trash.Harmful field trash refers to nonmetal inclusion and gas is mingled with in the steel in general.Particularly oil well pipe, Ultra-low carbon deep punching steel, pressure vessel steel etc. all have comparatively strict requirement to size, quantity and the distribution of field trash.Is the most dangerous as oxide and sulphide inculsion to pressure vessel wall, and field trash can crack the source; The deep-drawing sheet that is used for automobile, field trash can influence the surperficial coating quality and the drawing quality of Automobile Plate.Be mingled with the purpose that cleans molten steel for reaching to remove, people have developed multinomial tundish metallurgy technology.As use big capacity tundish; Use barricade and dam, filter (perforated baffle); Tundish Argon technology; Tundish uses suitable coverture; Gathering of STEEL BY CENTRIFUGAL FLOW TUNDISH field trash and removal technology etc.All these technology all exist impurity to remove poor effect, especially oxide in the impurity and sulfide are removed poor effect.
Summary of the invention
The purpose of this utility model is to provide a kind of tundish absorber of high adsorption capacity.
Tundish absorber of the present utility model is made up of ordered series of numbers bar post, and this post is staggered and arranges.
The bar column diameter is 30-70mm, and the bar intercolumniation is 10-20mm.
The bar post of absorber of the present utility model is formed by calcium oxide, magnesia refractory material, adopts MgO, CaO fire resistant materials to Al
2O
3, SiO
2Has efficient adsorptivity Deng field trash.The bar rod structure has increased the contact active area of molten steel with MgO, CaO fire resistant materials simultaneously, easily catches field trash.The absorber of this structure is difficult for stopping up, and the continuous cast crystallizer number also can reach same adsorption effect in the middle of prolonging like this.Molten steel becomes piston flow after by bar pillar absorber, has reduced liquid fluctuating, has reduced the interference and the flow dead of turbulent flow, has improved molten steel flow state branch.The bar post is staggered and has prolonged molten steel time of staying in tundish, and the triple weirs of tundish can change double weir into, can reach same metallurgical effect.Also reduced the obstruction of tundish submersed nozzle in addition.
Because absorber of the present utility model can be controlled tundish molten steel flow field form, make and puncture the stream minimizing, piston flow and upwards flow tendency enhancing, reduce liquid fluctuating, reduce the interference and the flow dead of turbulent flow, increase molten steel mean residence time in tundish, make its adsorption effect more obvious field trash, can make the content of oxide in the steel reduce 30%-55%, bulky grain is mingled with minimizing more than 50% in the steel.Tundish adsorber structure of the present utility model is simple, easy for installation.

The specific embodiment
The structure of tundish absorber of the present utility model is, respectively at the side mounting bar pillar absorber 4 of dam 5 near submersed nozzle 6, bar pillar absorber 4 is installed between the bottom plate 8,9, upper mounted plate 8 is cubic halfpace type, dug 4 rows, 9 row apertures in upper mounted plate 8, aperture is staggered and arranges.Bottom plate 9 is a U word halfpace type, can be installed in easily in the tundish 2, digs the aperture with the aperture correspondence of upper mounted plate 8 in bottom plate 9.Bar post 10 is mixed and made into by magnesia, calcium oxide, and bar post 10 is installed in the bottom plate 9, is putting upper mounted plate 8 then, and formed post is staggered and arranges.The last bottom plate 8,9 of bar pillar absorber 4 is common pushing off the slag weir plate.The bar intercolumniation is 12mm, and the diameter of bar post is 50mm.
