VALVE PLATE AND GATE VALVE IN OUTLET OPENING OF VESSEL FOR MELT METAL

摘要

FIELD: metallurgy. SUBSTANCE: valve plate includes refractory plate embracing its metallic envelope and centering unit. The last is formed by two bearing surfaces mutually spaced by predetermined distance. Said surfaces are arranged almost vertically in direction to plate support. Height of bearing surfaces is equal approximately to thickness of metallic envelope. After mounting and centering plate said bearing surfaces engage with bearing surfaces of metallic framework. EFFECT: enhanced accuracy of plate centering, low cost and simplicity for making them. 12 cl, 12 dwg
