A non-ferrous metal casting technology using metal mould and wet sand core includes selection of sand, mixing with water, making wet sand core, heating metal mould, putting wet sand core into metal mould, pouring molten metal, demoulding and removing sand core, and features the time for each...
PROBLEM TO BE SOLVED: To obtain a hot-top type continuous casting method, with which a high quality hollow billet can stably be obtd.;SOLUTION: In the method for continuously casting molten metal 3 continuously supplied in a molten metal holding part 2 into the hollow billet 1 in a casting...
A metal article is cast in an elongated mould of high thermal conductivity by introducing molten metal through the bottom portion of the mould. Molten metal is flowed into the mould so as to form a solidifying casting shell which during casting occupies >=40% of the cross-sectional mould area...
In this casting process, the time until the resin core melts or softens with the heat of the molten metal, is extended and the molten metal temp. is lowered to the solidified temp. or lower of the molten metal before developing the melting or the softening. By this method, when the ...
Process for casting a component from a light metal having; (i) a casting core consisting of a matrix infiltrated with infiltration channels comprises a docking phase in which a liquid melt enters the intermediate space between the core and a shell surrounding the core; (ii) an infiltration phas...
