Exothermic Heating of Cross Gates in Lost Foam Casting

Abstract

There have been developed three methods of manufacturing exothermic sleeves using a consumable pattern as a supporting structure. The methods include the use of hydrocarbon materials without additional pollution molding sand mixture kept at Lost Foam casting for multiple use. Calculation of production costs developed exothermic inserts by selecting optimal raw materials available in the domestic market, confirmed the effectiveness of their application. The concept of computer modeling of geometrical forms of the cross gate at Lost Foam Casting has been proposed.
