Abstract: In order to enhance greatly the strength of steel wires used for suspension bridge, stayed-cable bridge and tyre cord,a new method combining continuous unidirec-tional solidification process with low temperature (under recrystallization temperature) large deformation plastic working is presented for producing super high strength steel wires. The cast iron and stainless steel continuous cast ingots with unidirectional columnar crys-tals have been fabricated successfully. It is confirmed that the continuous unidirectional solidification process can be used for the forming of iron and steel materials.
