Problems solved by technology

The disadvantages of ordinary sand mold risers are: (1) the heat loss of the riser is fast, the volume of the riser is large, and the yield of the casting process is low; (2) the root of the riser is difficult to cut, especially the manganese steel casting riser, which is easy to cut When cracks occur, certain technological measures need to be taken, and at the same time, it is difficult to grind the remaining head of the riser cutting

Abstract

The invention discloses a manufacturing method of heating / heat-insulated washburn risers on inner / outer metal mold sand casting manganese steel crushing wall or rolling mortar wall, which comprises the following steps: (1) calculating the effective feeding distances of risers based on the fact that a crushing wall or a rolling mortar wall is the structural characteristic of a uniform-wall thickness annular closed casting and is the main thermal center, and determining the quantity, the shapes, the sizes and the positions of the risers; (2) respectively designing and manufacturing components of the heating / heat-insulated risers; (3) assembling components of heating / heat-insulated riser sleeves; assembling an outer metal mold with spread molding sand and an inner metal mold with spread molding sand and a tapered neck riser seat sleeve on a casting bottom plate, fastening the outer metal mold and the inner metal mold, covering a top box provided with the upper halves of the heating / heat-insulated riser sleeves, fastening with the outer metal mold and the inner metal mold into a whole casting mold, casting, and knocking off the risers after uncovering. By using the method to produce the manganese steel casting risers, the invention achieves obvious feeding effect, increases the production rate of the casting process, reduces the riser cutting cost and increases the economic benefits.

Description

technical field [0001] The invention relates to a casting method for a manganese steel crushing wall or a rolling mortar wall of a cone crusher, in particular to a method for manufacturing a manganese steel crushing wall or a rolling mortar wall of a cone crusher using inner and outer metal molds covered with sand to cast a heat-preserving and easy-to-cut riser. Background technique [0002] Cone crusher is a crushing equipment widely used in metallurgy, mining, building materials, refractory materials, energy and other industrial industries. The crushing wall and the rolling wall are the main wear parts of the cone crusher. Their quality directly affects the crushing efficiency and quality of raw materials, and also directly affects the output and technical and economic indicators of the product. [0003] At present, the wear-resistant parts of the crushing wall and rolling mortar wall used in the cone crusher are still mainly made of high-manganese steel ZGMn13, or trace a...
