Embodiment Construction

[0017] If certain words are used to refer to specific components in the description and claims, those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component, and the description and claims do not rely on the difference in names As a way to distinguish components, but the difference in function of components is used as a criterion for distinction. For example, "comprising" mentioned in the entire specification and claims is an open term, so it should be interpreted as "comprising But not limited to", "approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. However, the description is for the purpose of explaining the general principles of the present invention, and is not intended to limit the scope of the present invention. The scope of protection of the present invention should be ...

Abstract

The invention discloses a centrifugal pouring processing method of a papermaking dryer. The method comprises the following steps: preparing a pouring die; preheating the pouring die; mounting the preheated pouring die on a supporting wheel of a centrifugal machine; driving the pouring die to rotate through the supporting wheel of the centrifugal machine; pouring a first layer of molten iron into the pouring die, and forming a sleeve of the papermaking dryer under the centrifugal effect; after the first layer of molten iron is cooled, pouring a second layer of molten iron into the pouring die to form a boss of the papermaking dryer; after the first layer of molten water and the second layer of molten water are cooled, stopping the rotating of the centrifugal machine; removing the formed papermaking dryer; and annealing. The method has the characteristics that the papermaking dryer workpiece is formed by pouring twice under the centrifugal effect, so that the strength of the papermaking dryer is increased based on the centrifugal density; the overall quality is greatly improved; few wastes are produced; quality problems such as air pores and sand holes are avoided; the working intensity is reduced; the production period is reduced; the raw materials are saved; and the production cost is decreased.

Description

technical field [0001] The invention relates to the field of papermaking machinery, in particular to a centrifugal pouring processing method for a papermaking drying cylinder. Background technique [0002] The traditional papermaking dryer adopts sand casting, which is labor-intensive, requires many raw materials, long cycle, many waste products, many pores and sand holes, and poor environmental protection conditions. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned disadvantages and provide a processing method for centrifugal pouring of paper-making dryers. [0004] The technical solution adopted by the present invention to achieve the above object is: a papermaking drying cylinder centrifugal pouring processing method, comprising the following steps: [0005] a. Prepare the pouring mold: the pouring mold includes a cold form, a cover, and a baffle. A cover is installed at both ends of the hollow cylindrical cold f...
