The present invention describes an improved process for the commercial scale production of high-quality catalyst materials. These improved processes allow for production of catalysts that have very consistent batch to batch property and performance variations. In addition these improved processes allow for minimal production losses (by dramatically reducing the production of fines or small materials as part of the production process). The improved process involves multiple steps and uses calcining ovens that allow for precisely control temperature increases where the catalyst is homogenously heated. The calcining gas is released into a separate heating chamber, which contains the recirculation fan and the heat source. Catalysts that may be produced using this improved process include but are not limited to catlaysts that promote CO hydrogenation, reforming catalysts, Fischer Tropsch Catalysts, Greyrock GreyCat? catalysts, catalysts that homologate methanol, catalysts that promote hydrogenation of carbon compounds, and other catalysts used in industry.

A method for producing soft magnetic strip material for roll tape-wound cores with the following steps: preparing a band-shaped material, applying a heat-treatment temperature to the band-shaped material, and applying a tensile force to the temperature-applied band-shaped material in one longitudinal direction of the band-shaped material in order to produce a tensile stress in the band-shaped material, to produce the soft magnetic strip material from the band-shaped material, the method, moreover, comprising determining at least one magnetic measurement value of the soft magnetic strip material that has been produced and controlling the tensile force for setting the tensile stress in a reaction to the determined magnetic measurement value. Furthermore, a device for carrying out the method and a roll tape-wound core produced by means of the method are made available.

A shell (10) acts as a transporting shoe for steel ingots, which are pushed through a preferably tubular induction furnace for inductive heating for the purpose of producing seamless tubes by the extrusion process. The shell (10) is formed in such a way that it partially reaches around the contour of the steel ingot to be heated. The shell is provided at one end leading in the pushing-through direction or transporting direction, with a shoulder (12), which extends at an angle to the transporting direction, against which the steel ingot rests in such a way that the pushed-through steel ingot takes the shell (10) along with it. A method for inductively heating steel ingots uses a shell (10) as described.
