Method employed in the continuous casting of steel melted in a manner which gives a low hydrogen content

摘要

The invention relates to a method employed in the continuous casting of steel melted in a manner which gives a low hydrogen content. In this method, the hydrogen content of contact substances, such as refractory materials and casting powders, with which the molten steel comes into contact on its way from the casting ladle to the mould, is reduced before contact with the molten steel by a high-temperature vacuum treatment before casting on and a rise in the hydrogen content of the steel during casting is avoided.
