Abstract
A housing assembly of a sliding closure unit for controlling the discharge of molten metal from a metallurgical vessel includes a housing member mounted on the metallurgical vessel adjacent an outlet thereof, and a cover member mounted on the housing member by joints to enable the cover member to pivot with respect to the housing member and to be removable therefrom. The joints include joint bases on at least four sides of each of the housing and cover members and including, for each of the housing and cover members, first and second oppositely spaced sides with the joint bases thereof defining parallel first and second joint axes, respectively, and third and fourth oppositely spaced sides with the joint bases thereof defining parallel third and fourth axes, respectively. The joint bases on each side of the cover member face joint bases of a respective side of the housing member. The joints include attachment structure for selective attachment to the joint bases of the first and second sides of the housing and cover members or to the third and fourth sides of the housing and cover members, thereby to pivotally and removably connect the cover member to the housing member.
