Проблемы производства стальных бесшовных горячекатаных труб

This article is devoted to the problems of manufacturing of hot-rolled seamless pipes. One of them is a problem of “High-temperature oxidation”. There is a problem of creating dense and strong oxide layers of big thickness on the steel surface today. This problem is very important because oxide layer is used as a protective layer on swages which are used for manufacturing of seamless pipes. The oxide layer protects swage from heating and destruction
