Problems solved by technology

Chinese patent 02223021.1 discloses a crusher roller tooth plate, which is composed of an arc-shaped plate body, fan-shaped teeth on the arc-shaped plate body, and a dovetail tenon on the bottom surface of the arc-shaped plate body. Several tooth plates are mounted on the roller body. On the top, it constitutes the crusher roller. The tooth plate is cast with a single metal. The tooth plate cast with carbon steel has low hardness and poor wear resistance. The tooth plate cast with high chromium cast iron has poor toughness and the teeth are particularly easy break off

Embodiment Construction

[0013] The present invention will be further described below in conjunction with embodiment (accompanying drawing). refer to figure 1 As shown, the tooth-shaped partition is composed of a partition body 2 and teeth 1, the number of the teeth 1 is the same as the tooth cavity in the mold cavity, and the shape matches. Establish garden-shaped hole 3 on the tooth-shaped dividing plate, and this tooth-shaped dividing plate casts or punches with low carbon steel or medium carbon steel and makes. The method of pouring the composite tooth plate is to design the mold cavity. One side of the mold cavity has a tooth cavity and the other side has a dovetail cavity. In the tooth cavity of the mold cavity, the space between the tooth 1 and the tooth cavity is the poured high chromium alloy cast iron layer. At the same time, high-chromium alloy cast iron solution and carbon steel solution are respectively injected into the two cavities separated by the tooth-shaped partition. At the same ...

Abstract

The present invention discloses casting process and structure of composite toothed plate for crusher. The present invention has altered casting partition structure and thus altered distribution of high-chromium alloy cast iron layer and carbon steel in the work surface, raised inherent tooth toughness, increased coupling force of two kinds of alloy and obtained composite toothed plate with work surface of high-chromium alloy cast iron layer and processing surface of carbon steel layer. The composite toothed plate has dove tail tenon, lower part of the arced plate and inner layer of the teeth made of carbon steel, and upper part of the arced plate and the outer layer of the teeth made of alloy cast iron layer, and is suitable for production.

Description

[0001] Field [0002] The invention relates to a method for pouring a composite tooth plate of a crusher. [0003] The invention also relates to a composite tooth plate of a crusher. Background technique [0004] Chinese patent 88104776.7 discloses a method for pouring a composite liner of a ball mill. Its main feature is that the treated low-carbon steel plate is used as a partition between the high-chromium alloy cast iron and carbon steel, and double runners are used to feed the partition at the same time. Molten steel and molten iron are injected into the cavity formed by the plate and the cavity mold, and the molten steel and molten iron partially melt the partition, so that the molten steel, partition and molten iron are dissolved into one, and a ball mill with a high-chromium alloy cast iron layer on the surface and a carbon steel layer on the bottom layer is obtained. Composite lining. Chinese patent 02223021.1 discloses a crusher roller tooth plate, which is compose...
