The invention relates to a ceramic composite, in particular for use in secondary metallurgy, consisting of at least a first layer comprised of a carbon-containing, oxide refractory material, and a second layer comprised of a carbonless oxide refractory material bound with a binding agent.

Ceramic composite

A tubular refractory channel (,) that can be inserted as a flowthrough for liquid metal into a thermally insulating outer lining (,) and can be connected with the outer lining (,) by a refractory mortar layer (,). In order to prevent liquid metal from penetrating into the mortar layer (,), even if the mortar layer contracts, the outer lining (,) overlaps the metal inflow-side of a front face (,) of the channel (,).

Refractory channel with outer insulation and method for joint packing

An assembly includes a tapping device for flow therethrough of molten material and a cooled inductor to be connected to an electrical source and mounted with respect to the tapping device to be inductively coupled to one of the tapping device and the molten material flowing therethrough. The inductor includes an electrically conductive induction coil having therethrough at least one cooling passage. Each cooling passage has connected thereto at least one supply line for supply thereto of cooling fluid and at least one discharge line for discharge therefrom of the cooling fluids.

Assembly of a tapping device and a cooled inductor

In a process for splashing and/or teeming liquid metal, in particular steel, through a discharge in the wall or in the bottom of a metallurgical vessel, the discharge is electromagnetically coupled to the electromagnetic field of at least one fluid-cooled, in particular air-cooled, inductor. The inductor and the discharge are at least partially disposed in the wall or in the bottom of the metallurgical vessel. For teeming, the electromagnetic field of the inductor, or of the inductors, is coupled directly to the discharge and also the liquid metal. For this purpose, the frequency of the electromagnetic field or the electromagnetic fields, if appropriate, is adjusted correspondingly.

The invention pertains to a process and an apparatus for the discontinuous tapping of melts. An inductor surrounds a passage through which the melt is discharged from a vessel. The inductor applies radial electromagnetic energy to the passage to maintain the melt in a molten state. To stop flow of the melt through the passage, an outlet opening of the passage is closed and the inductor is electrically switched off while a cooling medium is flowed through the inductor. To begin flow of the melt, the outlet opening of the passage is opened and the inductor is electrically switched on.

A refractory guide member and a method for heating the refractory guide member by use of an inductor, where at least one collateral electromagnetic field located in a region spaced apart from the inductor is generated by the inductor. The mold part is made of an electrically conductive layer with several insulating interrupting slots for the controlled deflection of eddy currents from a main field generated by the inductor into a region spaced apart from the inductor.

In a method of operating an inductor of a tapping device of a melt vessel, the inductor couples inductively during a working phase with an electrically conductive shaped component and is cooled by means of a fluid. The inductor is electrically decoupled and cooled by means of a fluid in another working phase.

Assembly of tapping device and inductor therefor

A method and an apparatus for inductively heating a refractory shaped member provided with an internal space, particularly for a metallurgical vessel, enable as rapid, uniform heating of the shaped member as possible. An inner inductor is introduced into the internal space, the shaped member is heated from the interior by such inductor, and the inductor then is removed from the internal space.

This invention relates to a process for the manufacture of catalysts for the reduction of oxides of nitrogen from exhaust gases and in chemical air cleaning processes in which a catalytically active material containing iron ores, chromium ores and/or zeolite is placed in contact with a carrier means having a series of openings; e.g., wire mesh, expanded or perforated metal or any type of grid-like structure to form a catalytic member. The carrier means is etched with an acid etchant before forming the catalytic member or, instead, the catalytic member is etched with an acid etchant. The catalytic member is bonded by a thermal treatment; e.g., drying, tempering and/or fixing. This invention also relates to catalytic members or products produced by the process. This invention proposes the use of pressure bonding to obtain a catalytic member product which has significantly improved catalytic activity, greater mechanical strength and higher resistance to chipping.
