Abstract: front page image
(EN)A seal for a high temperature treatment vessel, particularly those common to the steel industry, has a primary purpose to prevent gases from escaping the treatment vessel.

L'obturation est assurée par un système de barrière constituée d'un rideau de gaz à pression positive, associé à une pluralité de joints mécaniques et à un moyen permettant d'aspirer les gaz qui s'échappent par les joints afin de les renvoyer dans la cuve.
