Solidification Curve Analysis of Cylindrical Casting by FEM
Abstract: In casting process, molten metal is solidified in mould cavity. Solidification process majorly classify into three different sections: (i) liquefaction (ii) solidify (iii) after solidification. In all three processes, one parameter which is called 'IHTC' (Intermediate Heat Transfer Coefficient), is varies with time. IHTC coefficient depends on shape, size, type of casting etc., so, it is continuously varies with all dependent functions. So, establishment of IHTC value is a very …
