Rotary casting mold chain and metallurgical molding machine with it

Abstract

The invention provides a rotational casting mold chain and a metallurgy casting machine with the rotational casting mold chain. Butt-joint faces between casting molds can be automatically cleaned, it is guaranteed that the butt-joint faces are in close fit, the service life of the casting molds is prolonged, and casting cost is reduced. The rotational casting mold chain is formed by connecting a plurality of casting molds in a chained mode. Each casting mold is provided with an arc butt-joint face. The portion, on one side of each casting mold, of the corresponding arc butt-joint face is of a downwards-recessed arc shape and the portion, on the other side of each casting mold, of the corresponding arc butt-joint face is a of a protruding arc shape. Every two adjacent casting molds are in butt joint in the mode that the corresponding protruding arc is located in the corresponding downwards-recessed arc. Each casting mold is provided with a chain shaft on one side and a fixing shaft on the other side. Every two casting molds are in chain connection through chain connection boards after being in butt joint. The casting molds and the chain connection boards are hinged on the chain shaft portions and fixed on the fixing shaft portions. The radian of the downwards-recessed arc and the radian of the corresponding protruding arc of each arc butt-joint face are identical. After every two casting molds are in butt joint and are in chain connection, the corresponding two casting molds are in sliding contact along the corresponding arc butt-joint faces so that the corresponding two casting molds can relatively rotate with the corresponding chain shaft serving as a circle center.

Description

technical field [0001] The invention relates to a rotary casting mold chain capable of continuously casting various metallurgical castings and a metallurgical casting machine with the same. Background technique [0002] Common in the field of continuous casting is the belt casting machine, which uses a channel casting mold with through grooves for continuous casting of various castings. The through groove of the groove casting mold of the belt molding machine is composed of a side stopper and a belt, and a setting mold composed of a belt and a convex device is arranged on the through groove, which can cast castings of various sizes product. However, since the belt itself is thin and long as a groove casting mold, and the side stopper and the belt are combined into a composite mold, the side stopper and the belt are deformed unevenly when casting high-temperature castings. Due to the different degrees of cold and heat deformation of the side block and the belt, when casting...

AI Technical Summary

Problems solved by technology

In the production process, mold sticking caused by casting burrs intruding into the gap often occurs, and there is slag inclusion in the process of opening and closing of the butt joint surface of the casting mold, resulting in seam warping

When mold sticking and slag inclusion problems occur, the chain-type metallurgical casting machine cannot self-clean and solve it, resulting in the need to stop midway to clean the casting mold, resulting in a decrease in production efficiency, and even condensation of high-temperature liquid in the casting tank

If the cleaning is not timely or thorough, starting the casting again will lead to problems such as missing molds and burning molds, resulting in damage to the machine and poor stability in continuous production

[0005] 2. Since the butt joint surfaces between the casting molds are at right angles, during the long-term high-temperature casting process, the high temperature difference between the side wall of the casting mold and the bottom of the casting mold will cause the casting mold to gradually bend and deform, and will gradually Create a gap between right-angled mating surfaces

This will also cause mold leakage and mold burning, resulting in the need to clean the mold or even replace the mold, which limits the service life of the mold

[0006] In short, because of the poor safety, stability and low life of the chain metallurgical casting machine, it has not been widely used in practice.

At present, nickel, chromium, manganese and other 20mm-70mm sections, blocks, and granules in the metallurgical industry are still produced by manpower crushing, machine crushing, and water quenching, which has high labor intensity, large dust particles, and high waste.
