Формирование тепловых граничных условий, связанных с излучением, при прессовании заготовок из меди и латуни

Abstract

On the basis of settlement and experience the conclusion about a big difference in formation of the thermal boundary conditions characterizing process of extrusion is made. It is revealed that speed of cooling of a article surface at the expense of radiation depends on degree of an material oxidation. By preparation transfer on a extrusion axis the oxidized surface of an ingot of the industrial sizes from copper or a copper alloy at the expense of radiation can cool down on 25 … 30оС.
