Crushing device for thrown cast sheets

Abstract

The invention discloses a crushing device for thrown cast sheets. The crushing device comprises a driving wheel disc, a collecting bin and a crushing bin; the driving wheel disc is fixed to the side surface of a roll wheel, is coaxial with the roll wheel and is driven to rotate by a copper roll motor, and first transmission teeth are arranged on the outer edge of the driving wheel disc; the collecting bin is located at the lower side of the roll wheel and is used for collecting the thrown cast sheets; the crushing bin is located at the lower side of the collecting bin and is provided with crushing teeth and crushing hoppers meshed with the crushing teeth, bearing supports are arranged at one ends of the crushing teeth and one ends of the crushing hoppers, and first driven wheel discs and second driven wheel discs meshed with the first driven wheel discs are arranged at the other ends of the crushing teeth and at the other ends of the crushing hoppers respectively; the first driven wheel discs are driven by the driving wheel disc to rotate through a transmission chain and drive the crushing teeth and the crushing hoppers to rotate axially and reversely. According to the invention, the cast sheets can be uniformly crushed, and the work efficiency of crushing the thrown cast sheets can be greatly improved.

Description

Technical field [0001] The invention relates to the field of vacuum quick-setting furnaces, in particular to a crushing device for strip casting slabs. Background technique [0002] The vacuum quick-solidifying furnace adopts the method of vacuum induction smelting. It uses the principle of electromagnetic induction to melt the metal raw materials in the crucible, and is cast through the tilting furnace system. The tundish is rapidly solidified by the condenser, and is separated from the condenser under the action of centrifugal force and thrown to water cooling. The inside of the pan is mechanically crushed and cooled by wind to form a scaly alloy cast piece. [0003] The cast slices just thrown out of the condenser are large in size. The existing vacuum induction melting furnaces in China generally use a motor-driven stirring mechanism. Through the relative movement between the stirring shovel and the water-cooled plate, the large cast pieces in the water-cooled plate are process...

AI Technical Summary

Problems solved by technology

However, the number and quality of the cast sheets used to accumulate in the water cooling plate are large, and the crushing effect is not ideal: the crushing is uneven, and the phenomenon of excessive crushing occurs, and a certain amount of broken powder is produced.

Due to the strong activity of the crushed powder, it is easy to oxidize in the subsequent transfer and dumping links, which will affect the quality of the product. Therefore, it is necessary to additionally screen out the crushed powder in the casting discharge link, which directly increases the production cost of the product and also affects the quality of the product. cast yield
