Abstract
The invention discloses a buffering splash-protection dovetail molten iron trough of a pig machine. The trough is designed into two sections of lap joint type dovetail structures and comprises a head buffering molten iron holding slot, a middle transition molten iron trough and a tail dovetail molten iron nozzle. The buffering splash-protection dovetail molten iron trough is integrally arranged between a molten iron tank of the pig machine and the upper chain belt of a driven wheel. Molten iron is cast to the head buffering molten iron holding slot through the molten iron tank and forms a molten bath, thereby relieving the impact of the molten iron. The middle transition molten iron trough buffers the flow of the molten iron twice, and the molten iron and the chain belt forms a 6-10 degree angle of inclination, and the even flow distribution of the molten iron enables the molten iron to evenly flow into a pig mold in a thin and wide waterfall shape. Compared with conventional integral molten iron troughs, the dovetail molten iron trough can reduce molten iron splashes, improve the yield of the molten iron, improve the working environment of operators, relieve the erosion to the pig mold and prolong the service life of the pig mold, and the surface quality of iron blocks is good. Moreover, transportation, installation and debugging are convenient, and meanwhile, the production and maintenance costs are reduced.
Description
Technical field
The present invention relates to the matching used buffering splash-protection dovetail molten iron trough of a kind of pig machine.
Background technology
Molten iron trough is the important corollary equipment of pig machine, can inject molten iron continuously by it to cooperate pig machine to finish the technical process of cast iron in the pig mold.At present pig machine is matching used is the monoblock type molten iron trough, and section is a rectangle, and molten iron stem bar and chain belt are in vertical direction.When hot-metal bottle was poured onto molten iron molten iron trough and flows in the pig mold again, molten iron splashed seriously, causes the recovery rate of molten iron lower, and the splash zone slag is serious.The spacing of stem bar bottom surface and pig mold can't be adjusted when mounted, causes molten iron to splash seriously equally, and the labour intensity during operative employee's scarfing cinder is big, work under bad environment.Molten iron stream is serious to the erosion of pig mold simultaneously, influences the service life of pig mold.
Summary of the invention
The present invention is intended to solve the problems referred to above that existing monoblock type molten iron trough in use exists, for pig machine provides a kind of safe, efficient, long-lived molten iron trough by improving structural design.Can significantly improve the result of use of pig machine, improve its production capacity and efficient, and increase the service life.
The present invention solves the problems of the technologies described above to have adopted following technical scheme:
This buffering splash-protection dovetail molten iron trough of pig machine, its structural design are two sections bridging type swallowtail-shaped structures.It comprises that the stem buffer-type connects molten iron tank, middle part transition molten iron trough and afterbody swallow-tail form molten iron stem bar.
This buffering splash-protection dovetail molten iron trough integral installation is between pig machine hot-metal bottle and driven pulley top chain belt.Molten iron is poured into the stem buffer-type by hot-metal bottle and connects molten iron tank and form the molten bath, thereby slows down the impact of molten iron.Middle part transition molten iron trough plays the middle part transitional function, the flowing of main purpose secondary buffer molten iron, and the length direction at stem and middle part can be adjusted simultaneously, adjusts the distance of pig mold and stem bar during more convenient the installation.Molten iron stem bar section is a swallow-tail form, and tap a blast furnace water nozzle and chain belt are 6 °～10 ° slanted angle, and the molten iron flow distribution is even, and the waterfall shape that can make molten iron be Bao Erkuan flows in the pig mold that slowly moves equably.
Compare with conventional monoblock type molten iron trough, can reduce splashing of molten iron, improve the recovery rate of molten iron, the iron block surface quality is good, operator's working environment is improved, slow down the erosion to pig mold, prolongs the service life of pig mold.And be convenient to transportation and Installation and Debugging, also reduced the production maintenance cost simultaneously.

The specific embodiment
Further introduce embodiments of the invention below in conjunction with accompanying drawing.
As shown in the figure, this buffering splash-protection dovetail molten iron trough of pig machine comprises that the stem buffer-type connects molten iron tank 3, middle part transition molten iron trough 4 and afterbody swallow-tail form molten iron stem bar 7, and their shell all is that low carbon steel plate is welded, groove inwall weldering anchor studs 8, and pouring fireproof material lining 6.
Ladle 1 snaps on the place ahead pillar 2, slowly tumble, the molten iron that ladle is 1 li flows into the stem buffer-type and connects molten iron tank 3, the stem buffer-type connects molten iron tank 3 and is installed between hot-metal bottle and the middle part transition molten iron trough 4, molten iron is cast in the stem buffer-type and connects molten iron tank formation molten bath, molten iron after the buffering flow to middle part transition molten iron trough 4, it is mounted in the stem buffer-type and connects between molten iron tank 3 and the swallow-tail form molten iron stem bar 7, the stem buffer-type connects molten iron tank 3 and overlaps up and down with middle part transition molten iron trough 4, by adjusting the lap of splice at stem and middle part, can adjust the distance of pig mold 5 and swallow-tail form molten iron stem bar 7.
Swallow-tail form molten iron stem bar 7 is installed in the rear of middle part transition molten iron trough 4, adopts bolt to connect, and is convenient to damage the back and in time changes.Tap a blast furnace water nozzle and chain belt is 8.5 ° slanted angle, and molten iron flows into pig mold 5 along 7 one-tenth waterfall shapes of swallow-tail form molten iron stem bar.
