A hoisting mechanism for raising a ladle filled with liquid steel from a transfer vehicle to immersion pipes of a vacuum treatment tank of an RH degasser. Two lifting arms are provided, one end of which can be brought into engagement with a support device formed on the ladle, and a bearing end of the arms is supported in a stationary saddle support comprised in such a way of a runway, disposed on the bearing ends of the lifting arms and having the shape of a circular arc, and of a path of rolling contact, adapted to axially fixedly guide the runway during pivoting of the lifting arms, that due to shifting of the point of load introduction in the saddle support occurring during a raising movement, reduction of a horizontal movement of the ladle occurs.

Hoisting mechanism for steel processing ladles in RH degassers

The invention relates to a process vessel for vacuum processing liquid steel, comprising a lower part, a middle part and an upper part, and submersible pipes located on the lower part, whereby the process vessel is provided with a heating apparatus, a feed device, and a waste gas connection arranged at a right angle to the central axis of the vessel, and whereby the process vessel has an outer metal jacket and a refractory lining arranged at least in part in the interior of the vessel, according to which the metal jacket ( ) of the upper part ( ) of the vessel, including the waste gas connection ( ), is provided with a water-cooling device ( ) and is exposed directly on the interior side to the process conditions prevailing in the interior of the vessel ( ).

Water cooled vessel for vacuum processing liquid steel

A lance is provided for processing molten metal baths located in metallurgical tanks, and for heating the tanks. A first lance body is displaceable in a second lance body. A mechanism is provided for displacing the first lance body relative to the second lance body such that in a raised burner position of the first lance body, burner nozzles disposed in the second lance body are uncovered by the first lance body and are axially spaced from the lance mouth of the first lance body to receive gas discharge from the lance mouth and to allow burner operation. In a lowered blower position of the first lance body, the burner nozzles are covered thereby. The mechanism for displacing the lance bodies relative to one another permits infinitely variable spacing of the burner nozzles from the lance mouth that is provided for the discharge of gas.

Vacuum tight reaction vessel for steel processing with a packing gland

Slide closure for melting pots

A vessel for processing steel under vacuum is provided and includes a vessel body, a cover placed thereupon in a vacuum-tight manner, and a connection for a vacuum pump. To heat the vessel a heating mechanism is provided that comprises a graphite rod that extends diametrically through the vessel, with contact studs being provided at the ends of the graphite rod for the transfer of electrical power. To increase the service life of the graphite rods, the rod with its contact studs is fixably held in position on the vessel wall at one end, and at the opposite end the rod is displaceably disposed relative to the vessel wall. To compensate the force originating from the vacuum that prevails in the vessel, a compensating mechanism that is acted upon by the vacuum of the vessel is provided for supporting the moveable mounting of the graphite rod.

Steel-processing vessel having a graphite rod heating means

With an airtight reaction vessel having a lining of refractory material for immersion in steel-processing ladles, especially for processing steel pursuant to the vacuum circulation process, including an upper vessel part, a lower vessel part, and immersion pipes, whereby these parts are interconnected via flange rings and clamping mechanisms that hold them together, the seal between the vessel parts is to be improved in every operating state. For this purpose, it is proposed that the respectively upper main flange (17) of the associated respectively lower vessel part (11, 13, 15) have a separate upper flange ring (19) that is placed upon the resilient end of an interposed compensator ring (20) and that in the unstressed state of the flange (17, 19) extends slightly beyond the upper rim of the vessel part (11, 13, 15).

an electric arc heating system for use with a vacuum metallurgic unit, which includes at least one graphite electrode that is composed of two or more interconnected graphite electrode sections and is adapted selectively to be lifted and lowered by lifting and lowering means from which it can easily be disconnected, while the electrode or electrodes is or are surrounded by a tubular mantle and the latter is surrounded by jacket means in a vacuum-tight manner which jacket means has that end thereof which is remote from the metallurgic unit provided with closure means for tightly closing an opening at the last mentioned end.
