Abstract
The invention discloses a kind of discharging structure of furnace cupola, the run-off that it comprises out the stream stock mouth on cupola crucible and adopts carbon brick to surround, run-off has spill cavity, stream stock mouth is communicated with spill cavity, and be positioned at the top of spill cavity, have the overfall be positioned at above furnace cupola fixed chute in the bottom of run-off, this overfall is communicated with spill cavity.After using the present invention, stream plume speed is comparatively slow, avoids and causes greater impact to centrifuge, decrease the infringement of convection current stock mouth simultaneously.
Description
Technical field
The present invention relates to a kind of discharging structure of furnace cupola, belong to furnace cupola technical field.
Background technology
At present, the furnace cupola head piece that existing rock wool produces generally adopts direct head piece to flow out through fixed chute, again by movable chute to centrifuge, the head piece shortcoming of this pattern is that heat insulation effect is not good, flow stock when putting molten iron to solidify at every turn, need with the dredging of oxygen airduct, time-consuming length and the infringement of convection current stock mouth is larger.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming prior art, provides a kind of discharging structure of furnace cupola, and its stream plume speed is comparatively slow, avoids and causes greater impact to centrifuge, decrease the infringement of convection current stock mouth simultaneously.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of discharging structure of furnace cupola, the run-off that it comprises out the stream stock mouth on cupola crucible and adopts carbon brick to surround, run-off has spill cavity, stream stock mouth is communicated with spill cavity, and be positioned at the top of spill cavity, have the overfall be positioned at above furnace cupola fixed chute in the bottom of run-off, this overfall is communicated with spill cavity.
Further, described overfall becomes up big and down small " V " type structure.
After have employed technique scheme, after stream stock mouth stream stock out needs to be full of run-off, flow into fixed chute again, the setting of run-off, just make stream plume speed slower, avoid the greater impact to centrifuge, meanwhile, after putting molten iron, the slag fusing that stream stock can slowly will solidify in run-off, again flow, decrease the infringement of oxygen airduct convection current stock mouth.
Accompanying drawing explanation
Fig. 1 is the structural representation of the discharging structure of furnace cupola of the present invention.
Detailed description of the invention
In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation,
As shown in Figure 1, a kind of discharging structure of furnace cupola, it is characterized in that: the run-off 2 that it comprises out the stream stock mouth 1-1 on cupola crucible 1 and adopts carbon brick 2-1 to surround, run-off 2 has spill cavity 2-2, stream stock mouth 1-1 is communicated with spill cavity 2-2, and be positioned at the top of spill cavity 2-2, have the overfall 4 be positioned at above furnace cupola fixed chute 3 in the bottom of run-off 2, this overfall 4 is communicated with spill cavity 2-2.
" V " type structure that overfall 4 one-tenth is up big and down small.
Operation principle of the present invention is as follows:
When in stove, material temperature reaches 1450-1500 DEG C, melting sources becomes liquid state to drip gradually, and in cupola well 1, liquid level is slowly long-pending high, when liquid level reaches stream stock mouth 1-1, be full of run-off 2 gradually, then flow out fibroblast, after letting slip molten iron through run-off 2 " V " type mouth, stream stock liquid level raises again, gradually by the recrement fusing in run-off, fibroblast again, even if can not directly melt, as long as oxygen blast a little, can again go out to flow stock.
Above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (2)
