Pouring flow inoculation feeding device

Abstract

A pouring stream inoculation charging device is provided with a casting ladle and a hopper storing an inoculation agent. A first supporting rod and a second supporting rod which share the same center line are fixed to the two sides of the hopper correspondingly. A charging opening is formed in the top of the hopper, and a plug is arranged in the charging opening. A discharging opening is formed in the bottom of the hopper. Supporting plates are fixed to the portion, on the two sides of the casting ladle, of the outer wall of the casting ladle correspondingly. A first fan-shaped trough plate and a second fan-shaped trough plate which are symmetrical in position are connected to the two supporting plates correspondingly. The first fan-shaped trough plate and the second fan-shaped trough plate are each provided with a plurality of radial grooves, the first supporting rod is placed in the corresponding radial grooves of the first fan-shaped trough plate, and the second supporting rod is placed in the corresponding radial grooves of the second fan-shaped trough plate. The first supporting rod is provided with insertion plates matched with the radial grooves of the first fan-shaped trough plate, and the insertion plates are inserted in the radial grooves of the first fan-shaped trough plate. By means of the pouring stream inoculation charging device, unintermittent manual operation is not needed in the pouring process, the angle of inclination of the hopper can be adjusted, and the inoculation treatment can be carried out on molten iron accurately and uniformly.

Description

technical field [0001] The invention relates to a non-hand-held pouring and flowing inoculation feeding device. Background technique [0002] In the production process of cast iron, the inoculation process is an indispensable process in the production process of modern cast iron. How to add less inoculant to the molten iron to change the solidification process of the molten iron, improve the as-cast structure, and improve the mechanical properties and processing performance , the inoculation process is very important. As far as ductile iron is concerned, inoculation can increase the tendency of graphite spheres to precipitate, and obtain evenly distributed, fine-grained graphite. Especially for the production of as-cast ductile iron, special attention should be paid to inoculation treatment. After selecting the inoculant variety, the addition method of the inoculant becomes the key. In the inoculation process, inoculation with flow is more difficult to control. At present...

AI Technical Summary

Problems solved by technology

Manually put a shelf on the sand box, and place a funnel containing a certain amount of inoculant on the shelf to incubate with the flow. This method requires special inoculation operators with flow, and the labor intensity of the operators is high.

There are also hanging funnels on the ladle nozzle for inoculation with the flow. Most of this method cannot ensure that the funnel can always be kept above the molten iron for inoculation during the process of different inclination angles of the ladle, and it is difficult to quantitatively and uniformly control the amount of addition, especially for the same product. Hand-held operation for a long time in the process of pouring in large quantities will cause a great test to the physical strength and energy of the incubating workers, and prolonging the pouring time will easily lead to spheroidization decline

The utility model with the Chinese patent application number 201020247336.5 discloses a flow inoculation device used on a hand-cast ladle, including a funnel assembly and a support frame assembly. However, when the ladle has a short spout or is not a teapot spout, the above utility model cannot keep the spout of the flow-following inoculation funnel above the cast iron flow. When the ladle is tilted to a certain angle, the inoculation funnel The inoculant will deviate from the molten iron flow
