Patent number: 10801082Abstract: A molten metal treatment lance includes a refractory having at least one channel extending through the refractory. A first tubular member having two open ends is located in the channel of the refractory. The first tubular member has a side wall having an inner surface and an outer surface. A second tubular member having an open end and a closed end is positioned in the first tubular member. The second tubular member has a side wall having an inner surface, an outer surface and at least one opening extending from the inner surface of the side wall of the second tubular member to the outer surface of the side wall of the second tubular member. The second tubular member is positioned in the first tubular member so as to form a space between the inner surface of the side wall of the first tubular member and the outer surface of the side wall of the second tubular member.Type: GrantFiled: November 3, 2015Date of Patent: October 13, 2020Assignee: J.W.

Patent number: 8783528Abstract: A slide gate includes first and second frame members, first and second nozzles, first and second plates, a biasing member, a hinge and an actuator. The first plate is connected to the first frame member. A passageway in the first nozzle is aligned with an opening in the first plate. The second plate is connected to the second frame member. A passageway in the second nozzle is aligned with an opening in the second plate. The biasing member includes a channel having a shaft extending through a spring located in the first frame member. The spring biases a retainer and the channel toward the first frame member. The second frame member includes a portion that rides in the channel. The actuator moves the second frame member along the channel to align the nozzle passageways to allow material to flow through the slide gate.Type: GrantFiled: August 29, 2011Date of Patent: July 22, 2014Assignee: J.W.

Patent number: 4887748Abstract: An apparatus and method for attaching the submerged nozzle to the lower plate of a sliding gate valve mechanism in a system in which such an assembly is replaceable during a continuous casting operation is disclosed in which the coupling of the lower plate to the submerged nozzle is achieved by way of a bayonet-type attachment between a lower plate container and a submerged nozzle retainer that is uniformly adjustable during operation. The assembly is first tightened snugly in a pre-operative condition, then loaded into an operative position where, after thermal and mechanical forces have acted on the assembly, it is adjusted into a fully tightened operational condition. At all times when the assembly is in (1) the pre-operative snug condition, (2) the operating fully tightened position, and (3) the full range of positions in between, handles are positioned wholely under the lower plate container, whereby unobstructed replacement and adjustment can take place.Type: GrantFiled: December 29, 1986Date of Patent: December 19, 1989Assignee: J.
