Method for manufacturing crushing wall or rolling mortar wall pouring system of cone crusher during sand-coated casting of inner/outer metal molds

Abstract

The invention discloses a method for manufacturing a crushing wall or rolling mortar wall pouring system of a cone crusher during the sand-coated casting of inner / outer metal molds, comprising the following steps of: (1) respectively designing and manufacturing units of the pouring system according to the different specifications of the crushing walls or the rolling mortar walls: a, sprue tube casting bricks, b, lane center bricks, c, cross gate runner bricks, d, in-gate elbow reducing bricks, and e, out-gate funnel bricks; (2) designing and manufacturing a pouring bottom plate; (3) orderly assembling the units of the pouring system on the pouring bottom plate; (4) assembling the outer and the inner metal molds coated with molding sand on the pouring bottom plate and closing a covering box; and (5) pouring with molten manganese steel, preserving the temperature and cooling. When the method is used for pouring the molds, the molten steel can stably and rapidly fulfill the casting molds; the units of the pouring system are clean and have strong scouring resistance; and the molten steel is poured in the molds without splashing and scouring the mold walls, thereby the high-quality castings with smooth surfaces and clear outlines can be obtained.

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 design and manufacture method for casting a casting system of a cone crusher crushing wall or a rolling mortar wall using inner and outer metal molds covered with sand. 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 alloy elements are added to the m...

AI Technical Summary

Problems solved by technology

The disadvantages are: the molding method is extensive, the efficiency is low, the dimensional accuracy of the casting is low, the surface roughness is poor, especially the thickness of the sand barrier layer of the sand barrier outer chiller is difficult to control, and the quality of the casting is unstable; sticky sand, sand holes, and burrs fly Casting defects such as edges are unavoidable; moreover, it is difficult to clean the water glass sand castings, and the follow-up process is labor-intensive and costly

At the same time, it is also difficult to reuse the old sand of sodium silicate sand. The ratio of iron to sand is generally 1:3~5, the load of old sand regeneration is heavy, and the investment of old sand recycling equipment is large.
