Description

да защитного газа круговое пространство дополнительно промываетс  защитным газом, так что нри применении защитного газа, свободного от водорода, создаетс  даже возможность удал ть водород из системы. Защитный газ удал етс  или через нижний край крыщки 8 или через отводной штуцер, который снабжен вентилем или сифонным затвором , так что в кольцевом пространстве остаетс  небольшой подпор защитного газа. При установлении определенного состава защитного газа, например аргона, с незначительным содержанием кислорода, становитс  возможным использовать обычно желательпые металлургические свойства шлака, например способность обессеривани .Yes, the protective gas is additionally flushed with protective gas, so that when using a protective gas that is free from hydrogen, it is even possible to remove the hydrogen from the system. The shielding gas is removed either through the lower edge of the lid 8 or through the outlet nipple, which is provided with a valve or a siphon valve, so that a small backing of the shielding gas remains in the annulus. When determining a specific composition of a protective gas, for example argon, with a low oxygen content, it becomes possible to use the usually desirable metallurgical properties of slag, for example, the desulfurization ability.

Предмет изобретени Subject invention

Крышка кристаллизатора электрошлаковой печи, имеюща  форму воронки и встроенный в нее патрубок подвода защитного газа, отличающа с  тем, что, с целью повышени  герметичности кристаллизатора, крышка своим нижним краем, образующим проходное отверстие дл  электрода, погружена в плавильное пространство кристаллизатора, а патрубок подвода газа вмонтирован п полость между кристаллизатором и крышкой.The cover of the electroslag furnace crystallizer, having a funnel shape and a protective gas supply nozzle embedded in it, is characterized in that the cover with its lower edge forming the through hole for the electrode is immersed in the melting space of the crystallizer and the gas supply nozzle A cavity is mounted between the mold and the cover.
