Abstract
The utility model provides a device for improving the calcium treatment effect of molten steel. The device comprises a bracket, wherein a wire feeder and a drive motor are arranged on the bracket; the drive motor is connected with a lifting component; the device is characterized in that one end of the wire feeder is connected with a silk thread; the silk thread is wrapped by a steel-structure conduit; an anti-scouring heat-resistant material is poured outside the steel-structure conduit; the length of the steel-structure conduit is greater than that of the anti-scouring heat-resistant material; a wire smoothing conduit is sleeved in the steel-structure conduit and outside the silk thread; one end of the wire smoothing conduit is connected with the wire feeder, and the other end extends to below the height of the anti-scouring heat-resistant material; a slider is fixed at one end of the steel-structure conduit and fixedly connected with a fixed wire conduit; and the other end of the fixed wire conduit is fixedly connected with the lifting component through the slider. The device provided by the utility model can obviously improve the Ca yield in a calcium wire, stabilize the [Ca]Tot content in molten steel and reduce secondary oxidation of the molten steel in wire feeding.
Description
Technical field
The utility model relates to a kind of steel-making ladle furnace secondary refining equipment, relates in particular to a kind of device that improves molten steel calcium treatment effect.
Background technology
In the metallurgy industry, be used for steel-making ladle secondary refining equipment, when producing Al deoxidization steel and high-grade pipe line steel, in order effectively to prevent stopper nozzle clogging in the casting cycle and the quality accidents such as pipe line steel inefficacy that caused by hydrogen induced cracking, must carry out denaturing treatment to sulfide in the molten steel and oxide compound, in molten steel, feed Ca-Si or Ca-Fe line usually to MnS and Al
2O
3Be mingled with and carry out denaturing treatment, LF, RH, VD(LF, RH, VD are the abbreviation of liquid steel refining mode) etc. the ladle refining furnace molten steel [Ca] that disposes
Tot([Ca]
TotBe the form of presentation of Ca content in the molten steel) control in 20-50 * 10
-6, with MnS and Al
2O
3Type impurity becomes spherical calcium-aluminate or CaO-CaS-Al
2O
3Be mingled with.But in actual production, because ladle slag crust, slag blanket are thicker, the influence of factor such as oxygen level height in the slag, silk thread often occurs to loop or oxidized property slag oxidation phenomenon at the slag layer, cause Ca recovery rate instability in the calcium line, in the molten steel [Ca]
TotOn the low side, can not realize the purpose of the complete sex change of nonmetal inclusion in the molten steel.
Summary of the invention
Technical problem to be solved in the utility model is exactly at the existing in prior technology deficiency, and a kind of Ca recovery rate in the calcium line that can significantly improve is provided, and stablizes [Ca] in the molten steel
TotThe device of the raising molten steel calcium treatment effect of secondary oxidation of steel when silk is fed in content and minimizing.
This programme is realized by following technical measures: the device that improves molten steel calcium treatment effect, comprise support, this support is provided with wire feeder and drive-motor, this drive-motor is connected with lift component, described wire feeder one end is connected with silk thread, this silk thread is wrapped with the steel construction conduit, this steel construction conduit is cast with the antiscour high temperature material outward, the length of described steel construction conduit is greater than the length of antiscour high temperature material, in the described steel construction conduit, silk thread is set with outward along wire conduit, should be connected with wire feeder along wire conduit one end, the other end extend into below the antiscour high temperature material height, described steel construction conduit one end fixedly has slide block, and this slide block is fixedly connected with the fixing cord pipe, and this fixing cord pipeline the other end is fixedlyed connected with lift component by slide block.
