Abstract
The invention provides a ferronickel casting device, which is used for casting molten iron obtained by smelting into iron blocks and comprises a pig casting machine, wherein the upward inclination angle of the pig casting machine is 8 degrees. The ferronickel cast iron device has the advantages of improving the casting efficiency and reducing the splashing of molten iron.
Description
Technical Field
The invention belongs to the field of steel casting equipment, and particularly relates to a ferronickel cast iron device.
Background
The iron casting machine is arranged for continuously casting molten iron obtained by smelting into iron blocks, the molten iron is conveyed to the iron casting machine through the molten iron tank, lifted and inclined by the lifting hook, so that the molten iron in the tank is slowly injected into the iron runner, and then flows into the iron casting mold through the iron runner. Design requirements for pig machines include: 1) the splashing loss of the molten iron and the loss of the molten iron removed from the cast iron mold are reduced as much as possible in the casting process, and the quality of the cast iron blocks is ensured while the yield of the molten iron is improved. The original angle of inclination of the pig casting machine in our factory is 6 degrees, and the flatness is large, so that the following problems exist in the using process: 1) the dip angle is small, the flow speed of molten iron is low, and the casting speed is low; 2) the splashing loss of the molten iron is serious, about 10 kg/ton, and the splashed molten iron is solidified into iron slag which is difficult to clean.
In order to solve the problems, improve the casting efficiency and reduce the splashing of molten iron, an ideal technical solution is always sought.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, and provides a ferronickel cast iron device which can improve the casting speed and reduce the splashing of molten iron.
A ferronickel iron casting device comprises an iron casting machine, wherein the upward inclination angle of the iron casting machine is 8 degrees.
Based on the above, the device also comprises a chute and a buffer bag corresponding to the outlet of the chute, wherein the outer side of the buffer bag is provided with a diversion trench, and the diversion trench is arranged corresponding to the pig machine.
On the basis, the tail end of the diversion trench is provided with a rectifying part, the inner wall of the rectifying part is arc-shaped, and a drainage port is formed in the lower middle side of the rectifying part.
Based on the above, the rectification part further comprises a groove-shaped protection end on the rear side of the rectification part, the protection end is communicated with the inner cavity of the rectification part through the drainage port, and a discharge port is formed in the bottom of the protection end.
Based on the above, the outlet of the buffer packet corresponding to the diversion trench is located at the lower part of the buffer packet.
Compared with the prior art, the invention has outstanding substantive characteristics and remarkable progress, and particularly, the angle of inclination of the pig casting machine is 8 degrees, and the angle of inclination is not increased excessively to ensure that molten iron can effectively fill a casting mold due to the limitation of the length of the pig casting machine. Because the inclination angle is increased, the flowing of the molten iron on the pig casting machine is accelerated, the rebound angle of the molten iron after the molten iron collides with the pig casting machine is increased, the casting efficiency of the pig casting machine is increased, the loss caused by the rebound splashing of the molten iron is reduced, the splashing loss of the molten iron is reduced to about 0.5 kg/ton from about 10 kg/ton, and the effect is remarkable.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Fig. 2 is a partially enlarged schematic view of fig. 1.
Fig. 3 is a partially enlarged schematic view of fig. 2.
In the figure, the device comprises a chute 1, a buffer bag 2, a discharge opening 3, a diversion trench 4, an iron casting machine 5, a rectifying part 6, a protection end 7 and a drainage opening 8.
Detailed Description
The technical solution of the present invention is further described in detail by the following embodiments.
As shown in fig. 1, 2 and 3, a ferronickel iron casting plant comprises a casting machine 5, which is inclined at an upward angle of 8 °. The invention also comprises a chute 1 and a buffer bag 2 corresponding to the outlet of the chute 1, wherein the outer side of the buffer bag is provided with a diversion trench 4, and the diversion trench 4 is arranged corresponding to the pig casting machine 5. The inlet end of the chute 1 corresponds to the electric furnace, the refined molten iron directly enters the chute 1 from the electric furnace, then flows into the buffer bag 2 through the chute 1, and is cast after passing through the diversion trench 4. Continuous operation from tapping to casting avoids the transfer of molten iron from a molten iron tank, improves the casting efficiency and reduces the production cost.
The end of guiding gutter 4 is provided with rectification portion 6, the inner wall of rectification portion 6 is the arc, and the arc inner wall can guide the molten iron to form the vortex, drainage mouth 8 has been seted up to the well downside of rectification portion 6, and the molten iron that forms the vortex is followed drainage mouth 8 flows out. The invention utilizes the shearing and wrapping effect of vortex in fluid mechanics to reduce the splashing of loose liquid drops at the edge of the fluid and reduce the splashing in the process that molten iron flows to the pig casting machine 5.
In order to prevent the molten iron from splashing after the molten iron comes out from the drainage port 8, the rectifying part 6 further comprises a groove-shaped protection end 7 on the rear side of the rectifying part, the protection end 7 is communicated with an inner cavity of the rectifying part 6 through the drainage port 8, a discharge port 3 is formed in the bottom of the protection end 7, and the molten iron flows out of the drainage port 8 and then flows into the pig casting machine 5 through the discharge port 3.
In order to intercept slag in the molten iron, the outlet of the buffer ladle 2 corresponding to the diversion trench 4 is positioned at the middle lower part of the buffer ladle 2 because most of the slag floats on the liquid level of the molten iron. The arrangement reduces slag in molten iron from entering the cast iron mold, increases the smoothness of the surface of the cast iron block, and improves the quality of the cast iron block.
Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present invention and not to limit the same; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
