Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal casting of rolls, and particularly relates to an auxiliary material adding device for centrifugal casting of rolls. Background Art

[0002] Centrifugal casting is a casting process that uses centrifugal force to manufacture metal parts. In this process, molten metal is poured into one or more rotating molds. Under the action of centrifugal force, the metal liquid is pushed towards the mold wall and solidifies into the required shape. This method can produce castings with high density, fine grain structure and good mechanical properties. Currently, in the production of alloy roll centrifugal casting, auxiliary materials need to be added. Most of the existing auxiliary material adding devices use long-handled spoons for addition, which is inconvenient to operate and not easy to control the addition amount of auxiliary materials.

[0003] In the technical solution disclosed in the patent with the patent publication number CN214768794U and the patent name of an auxiliary material adding device for centrifugal casting of rolls, a certain amount of auxiliary materials are pre-weighed and placed in the hopper as needed. By hinging the valve on the bracket, the hopper and the guide pipe can be rotated by rotating the valve, which is convenient for emptying the auxiliary materials in the hopper. Through the setting of the flatbed truck, the transportation of the auxiliary materials is convenient. A counterweight block is placed at the rear end of the flatbed truck to play a balancing role, but it increases the transportation weight additionally. After each pouring of the outer wall is completed, it is necessary to return to the auxiliary material storage position to pick up materials, which is rather cumbersome. Content of the Utility Model
