    Abstract: The procedure for manufacturing fireproof crucibles for steel-processing ladles, in which aluminum deoxidation is carried out for the total quenching of liquid steel, is such that a monolithically hardening fireproof mass with a proportion of silicon dioxide is placed between the inside wall of the ladle and a reusable plug that is installed therein. After the plug has been removed, the ladle is put into use again, at which time a layer that contains alumina builds up on the hot side of the fireproof crucible and a highly sintered layer of greater hardness forms behind this. It is intended that a procedure such as this should simplify the reestablishment of the fireproof lining when the limits of use are reached, in view of the use of a layer that contains alumina and the highly sintered layer located behind this on the inside wall of the crucible. To this end, after a number of charges have been processed, a second crucible is installed as an expendable crucible within the first crucible, which now forms a safety crucible, this being done with the help of an appropriately smaller plug; when this reaches its limits of use it is broken out and the layer is reinstalled.

    Abstract: An adjustable form used for forming or repairing a refractory lining includes an adjustable frame constructed from a plurality of intersecting beams, at least some of which are adjustable, and a form connected to the adjustable frame. The frame can be adjusted in at least one direction and, preferably, in more than one direction. By properly adjusting the frame, the adjustable form can be used to form a refractory lining in different metal containment devices varying in dimensions, and can also be used to repair existing refractory linings. The adjustable form is inserted into a metal containment device at a distance from the floor and walls of the metal containment device, and refractory material is poured into the space between the adjustable form and the metal containment device.

    Abstract: A fixture (30) adapted to permit the heated exchange of a liner (14) from an operating vertical furnace (10). The fixture is adapted to secure to the base of the liner (14) to both unlock and lower the heated liner, such as a silicon carbide liner, at an controlled rate. The fixture is also adapted to elevate a new liner into the operating vertical furnace at a controlled rate to control the rate of heating of the liner as it is inserted into the operating vertical furnace. The fixture includes an inner ring (34), a low-friction Teflonnull ring (36), and an outer ring (38) permitting the rotation of the inner ring within the outer ring. Advantageously, the low friction ring comprises a flanged portion and a vertical portion allowing rotation of the inner ring within the outer ring even when elevated at extreme temperatures exceeding 500null C.

    Abstract: A solidified residual iron within a blast furnace is suspended up by employing a shell suspending device fixed to a tuyere arranged in a lower end portion of an upper portion of a furnace body suspended by a lift jack and a solidified residual iron suspending band, thereafter is descended by employing the lift jack and is mounted on a horizontally moving table. Subsequently, the horizontally moving table mounting the solidified residual iron thereon is moved onto a furnace outer truck rail from a furnace inner truck rail so as to be taken out of the furnace by operating a center hole jack arranged near the furnace outer truck rail, whereby an operation of taking out the solidified residual iron within the blast furnace out of the furnace is economically performed for a short time.
