Technique for producing dual-liquid dual-metal composite wear-resistant lining plate by lost foam casting

Abstract

The invention relates to a technique for producing a dual-liquid dual-metal composite wear-resistant lining plate by lost foam casting, comprising the following steps: 1) manufacturing a foam lining plate model; 2) installing two casting systems; 3) coating lost foam paint on the foam lining plate models, and baking; 4) adding dried quartz sand and compacting; 5) continuously adding the dried quartz sand to be full, then using a plastic film to cover and seal a sand box, installing a sprue cup to respectively connect a wear-resistant straight pouring gate of a lower spure and a casting steel straight sprue of an upper sprue, and vacuumizing a gas path on the lost foam sand box so as to fasten a casting mold; 6) firstly pouring wear-resistant molten iron, and then pouring molten steel; and 7) after the pouring is finished, closing a vacuum system of the lost foam till the dual-liquid dual-metal composite wear-resistant lining plate is taken out of the box after solidification and cooling. The technique has the beneficial effects that the service life is prolonged, the large amount of metal materials are saved, the difficult problem of hard matching of the wear resistance and the toughness of a whole piece is solved, and the difficult problems of no mixing and no box collapse when the lost foam is used for pouring two types of molten iron are overcome.

AI Technical Summary

Benefits of technology

This patented technology allows for making different types of plates called liners or cerams (metals) through use of special techniques like liquid droplets spray onto them before they harden. By applying these coatings on top of each sheet after being dried, the resulting material becomes more durable than regular cast aluminum sheets. Additionally, when producing certain alloys containing magnetic particles, the technique helps prevent melting and cool down the metal while still allowing it to form properly. Overall, this method simplifies manufacturing processes and increases their lifespan and reduces costs compared to conventional methods.

Problems solved by technology

Lined plates have been developed over time by different companies with specific needs due to their use in various fields like transportation, material processing or construction processes. These plating systems require durability against wearing caused by heavy metal alloys while also having excellent shock absorption properties without losing effectiveness when applied on surfaces subjected to stress concentration. However, current methods often result in poor performance at these areas because they lack sufficient impact tension and rigorous manufacturing standards required for highly demandable products.
