Abstract
The utility model belongs to the field of vacuum circulating refining furnaces, and particularly relates to a vacuum circulating refining furnace with three dip pipes. The three dip pipes are adopted at the lower part of a vacuum chamber, wherein one dip pipe is used for enabling molten steel to ascend by utilizing the principle of a bubble pump, the other two dip pipes are used for enabling the molten steel to descend and changing the speed of the molten steel by increasing the amount of the dip pipes, thus the corrosion for the dip pipes is reduced; meanwhile, by utilizing angles among the three dip pipes, the stirring effect of the molten steel is improved, and the circulation of the molten steel is improved. According to the method disclosed by the utility model, the problem that the dip pipe for enabling the molten steel to descend is short in service life can be effectively solved, and the problem that the circulation of the molten steel is non-uniform at the later period of using the dip pipes is solved through the circulating angles of the molten steel.
Description
Technical field
The utility model belongs to vacuum cycle refining furnace field, specifically a kind of three soaking tub vacuum cycle refining furnaces.
Background technology
RH(vacuum cycle refining furnace) be a kind of conventional refining unit, along with the requirement to Molten Steel Cleanliness is more and more higher, RH has born the responsibility of dark desulfurization, and add sweetening agent very large to the infringement of soaking tub, particularly large to the damage of the soaking tub declining for molten steel, in the use latter stage of dipping, can cause molten steel circulation inhomogeneous.
Summary of the invention
Technical problem to be solved in the utility model is: how to reduce molten steel circulation ununiformity, effectively reduce the erosion of molten steel to soaking tub, promote soaking tub work-ing life.
The technical scheme that the utility model adopts is: a kind of three soaking tub vacuum cycle refining furnaces, comprise cylindric vacuum chamber, the first soaking tub, the second soaking tub, the 3rd soaking tub, described vacuum chamber is cylindric, inner hollow, bottom is communicated with respectively with described the first soaking tub, described the second soaking tub, described the 3rd soaking tub.
As a kind of optimal way: the line of the horizontal section of the axis of described the first soaking tub, described the second soaking tub, described the 3rd soaking tub forms the equilateral triangle of a center of gravity on vacuum chamber axis extended line, and the length of side of described equilateral triangle and vacuum chamber diameter ratio are 0.4 ~ 0.55.
As a kind of optimal way: the diameter of described the first soaking tub is the 20%-30% of vacuum chamber diameter, the equal diameters of described the second soaking tub and described the 3rd soaking tub, described the first soaking tub diameter and described the second soaking tub diameter ratio are 1 ~ 1.4.
The beneficial effects of the utility model are: by using the utility model, can increase the life-span of vacuum chamber and soaking tub, improve molten steel circulating effect.
Accompanying drawing explanation
Fig. 1 is front view schematic diagram of the present utility model;
Fig. 2 is vertical view schematic diagram of the present utility model;
Fig. 3 is left view schematic diagram of the present utility model.
Wherein, the 1, first soaking tub, the 2, second soaking tub, the 3, the 3rd soaking tub, 4, valve tube.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model mainly comprises the first soaking tub 1, the second soaking tub 2, the 3rd soaking tub 3, valve tube 4, and wherein the first soaking tub 1 is used for making molten steel rises, and the second soaking tub 2, the 3rd soaking tub 3 decline for molten steel.
The line of the horizontal section of the axis of described the first soaking tub 1, described the second soaking tub 2, described the 3rd soaking tub 3 forms the equilateral triangle of a center of gravity on vacuum chamber 4 axis extended lines as shown in Figure 2, the length of side of equilateral triangle is 1/2 of vacuum chamber 4 diameters, the diameter of the first soaking tub 1 is that 0.25, the first soaking tub diameter 1, the second soaking tub diameter 2, the 3rd soaking tub 3 of vacuum chamber diameter 4 equates.
The present embodiment is only preferred embodiment of the present utility model; not the utility model is done to any pro forma restriction; those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in protection domain of the present utility model.
