摘要： A smelting ladle and a method for improving use efficiency thereof. The smelting ladle includes a housing, a working layer, and a permanent layer. The method includes: 1) rebuilding the working layer to have an outer layer and an inner layer, the inner layer being a consumable working layer which contacts with molten steel and steel slag, and the outer layer being a circulating working layer which contacts with the permanent layer or directly contacts with the housing; 2) allowing the smelting ladle to work, when the thickness of the consumable working layer is reduced to be between 0 and 20 mm, removing a residue of the consumable working layer and masoning a new consumable working layer for the smelting ladle; and 3) repeating 2) until the circulating working layer reaches a designed service life thereof, and casting a new circulating working layer for the smelting ladle.

摘要： Method and geometrical arrangement of refractories within a high temperature vessel. A protuberance near the periphery of the vessel opening is formed on an inner surface and a ring of trapezoidally-shaped refractory brick is positioned such that a sloping surface of each of the trapezoidally-shaped brick is preferably initially in contact with an adjacent surface of the protuberance. When the interior of the vessel is heated and the brick expand, they tend to ride upwardly, with the sloping surfaces urging the brick inwardly thereby increasing lateral friction therebetween, thereby holding them in place and preventing them from moving even when the vessel is tilted or turned upside down.

摘要： A tuckstone assembly (14) for an industrial type furnace (10) fills a space between a wall of the furnace and a supporting member (19) that supports the furnace superstructure. The tuckstone assembly (14) has a support block (26) having a sloped upper surface (27) and a nose block (37) having a mating sloped lower surface (38). The longitudinal profile of the tuckstone is reduced for insertion in the space of the furnace wall by sliding the nose block forwardly, and the enlarged nose portion (42) is made to cover the support plate (19) by sliding the nose block (37) back to where the ends of the support block and the nose block substantially coincide.

摘要： The device mounted at the end of an operating arm comprises one or more suckers for supporting objects, for example refractory bricks for the brick-lining of a metallurgical converter, means for linear and angular displacement of the suckers, sensors for monitoring and controlling automatically the means of displacement in order to grip and position the objects in a predetermined location, after immobilization of the operating arm. The suckers are provided on a sucker-carrying plate which in its turn is supported by a pair of blocks which can slide in transverse slide bars of a carriage which comprises a pair of longitudinal slide bars, perpendicular to the transverse slide bars and housed in sliding fashion in a central support attached to the end of the operating arm with a degree of angular freedom and a degree of linear freedom orthogonal to the axes of the longitudinal and transverse slide bars.
