DEGASSING LAUNDER
A degassing launder having a plurality of partition plates configured to block a flow of molten aluminum and including a plurality of domes. Two adjacent partition plates and two side walls of the launder form a degassing chamber. A lower portion of the partition plates is provided with a passage through which the molten aluminum flows into a next degassing chamber. The domes are arranged on the bottom of the launder.
Process for the Commercial Production of High-Quality Catalyst Material
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 catalysts 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.
Vertical batch furnace assembly comprising a cooling gas supply
A vertical batch furnace assembly, comprising a core tube, an outer casing, a cooling chamber bounded and enclosed by the outer casing and the core tube, and at least one cooling gas supply emanating in the cooling chamber. The core tube has an elongated circumferential wall extending in a longitudinal direction, and is configured to accommodate wafers for processing in the vertical batch furnace. The outer casing extends around the core tube and comprises a heating element for applying a thermal treatment to wafers accommodated in the core tube. The at least one cooling gas supply comprises at least one cooling gas supply opening which is arranged such that the cooling gas enters the cooling chamber with a flow direction which is substantially tangent to the circumferential wall.
FURNACE, FLUID FEED COMPONENT, FLUID REFORMING SYSTEM AND METHOD OF REFORMING A FLUID
There is disclosed a furnace (10), a fluid feed component, a fluid reforming system, and a method of reforming a fluid (20). The furnace (10) comprises a vessel (12) that defines a chamber (14) for holding a body of liquid (16). A fluid inlet (18) is provided for introducing a fluid (20) into the chamber (14) below a level (22) of the body of liquid (16) to cause the fluid (20) to interact with the liquid (16) and to migrate therethrough towards an outlet (24) for discharging a product (26) of the interaction from the chamber (14). A liquid circulation passage (28) is implemented, having a weir (30) which is operatively located near the level of the body of liquid (16), and a port (34) which is located remote from the weir (30) and in fluid (20) communication with the fluid inlet (18) so as to enable the liquid (16) to flow over the weir (30) through the liquid circulation passage (28) and through the port (34).

Gas injection system, furnace provided with such a system and use thereof
A gas injection system includes a tubular wall 3 capable of being thermally stressed and having a proximal extremity and a distal extremity 11, at the distal extremity, at least one extremity opening through which at least one gas is projected. A cooling is system located in the tubular wall including axial channels 12 which extend axially towards the distal extremity and in which a cooling fluid is circulated. Connecting channels 13 circumferentially join the axial channels to each other at the distal extremity of the tubular wall. The connecting channels, which circumferentially join the axial channels at the distal extremity of the tubular wall, have a rounded shape in the direction of the distal extremity.
METHOD FOR PRODUCTION OF A NITRIDED PACKAGING STEEL
A method for producing a nitrided packaging steel from a hot-rolled steel product with a carbon content of 400 to 1200 ppm, utilizing a cold-rolling of the steel product to a flat steel product, subsequent recrystallization annealing of the cold-rolled flat steel product in an annealing furnace, in particular a continuous annealing furnace. A nitrogen-containing gas is supplied into the annealing furnace and is directed at the flat steel product to introduce unbonded nitrogen into the flat steel product in an amount corresponding to a concentration of more than 100 ppm, or to increase the amount of unbonded nitrogen in the flat steel product to a concentration of more than 100 ppm, and subsequent cooling of the recrystallized annealed flat steel product at a cooling rate of at least 100 K/s directly after the recrystallization annealing. Using this method, cold-rolled flat steel products may be produced for packaging purposes with a tensile strength of more than 650 MPa and in particular between 700 and 850 MPa.
APPARATUS FOR REFINING MOLTEN ALUMINUM ALLOYS
Disclosed is a flux injector assembly and method for refining a molten material, wherein at least a portion of the material is aluminum, as it flows through a trough. A dispensing rod having a hollow body and a dispensing rim is configured to allow a flux and/or inert gas to travel through the hollow body and be injected into the molten material through the dispensing rim as the molten material flows through the trough. A baffle plate is configured to be positioned within the molten material in the associated trough to allow the molten material to flow passed the baffle plate. The elongated dispensing rod is positioned at a downstream location relative to the baffle plate. The rate of flow of molten material is increased as it passes the dispensing rim of the elongated dispensing rod to inject and mix the flux within the molten aluminum alloy.
LANCE AND METHOD FOR DETERMINING REACTION DATA OF THE COURSE OF A REACTION
A lance and a method determine reaction data of the course of a reaction, in which a reaction gas is top-blown by at least one lance onto a metallic melt in a metallurgical vessel and measured data are determined in this way, reaction data for the course of the reaction are determined as a function of these, where the lance for determining measured data blows out a gas which is conveyed separately from the reaction gas through at least one outlet opening of at least one measuring conduit. The lance for determining measured data blows out the gas which is conveyed separately from the reaction gas laterally through at least one outlet opening of at least one measuring conduit and the internal pressure of at least one gas bubble of this gas formed at this outlet opening of the respective measuring conduit is measured.
