Problems solved by technology

[0004] The manufacturing method of high-performance ductile iron drums includes at least the processes of material casting, brushing, and pouring. In the current casting process of iron drums, the production cost of finished castings is too high, and the investment in processing equipment is too large. Not only the casting process is more , affecting production capacity, and the accuracy of castings cannot be effectively guaranteed, resulting in a high scrap rate

Abstract

The invention discloses a manufacturing method for a high-performance ductile iron drum and mainly solves the problem of one-step cast molding. Through researches on high-performance ductile iron, a casting material, a coating and casting processes, the manufacturing process of the drum is simplified, the utilization ratio of the material is increased, energy conservation and consumption reduction are achieved, and the production cost is obviously reduced on the premise of obviously improving the mechanical properties and using performance of the drum, and meeting the requirement on the geometric dimension of a drum rope groove. Therefore, by adopting the manufacturing method disclosed by the invention, processing equipment investment and the production cost are reduced, great economic benefits are achieved, energy conservation and consumption reduction are achieved, and social benefits are significant. The manufacturing method is mainly suitable for casting of crane drums.

Description

[0001] technical field [0002] The invention belongs to the technical field of casting, and in particular relates to a method for manufacturing a high-performance nodular iron reel. [0003] Background technique [0004] The manufacturing method of high-performance ductile iron drums includes at least the processes of material casting, brushing, and pouring. In the current casting process of iron drums, the production cost of finished castings is too high, and the investment in processing equipment is too large. Not only the casting process is more , affecting production capacity, while the accuracy of castings cannot be effectively guaranteed, and the scrap rate is high. [0005] Contents of the invention [0006] In order to overcome the above-mentioned technical problems existing in the prior art field, the object of the present invention is to provide a high-performance nodular iron reel manufacturing method, which can directly cast a high-performance nodular ...
