摘要： A method for the continuous production of steel using metal charge material that is preheated in an upper part of a melting vessel, is then melted in a lower part of the melting vessel with fossil fuels and the molten material is continuously discharged into a treatment vessel in which the desired steel quality is adjusted while gases are introduced into the melting vessel from the exterior to afterburn the melting exhaust gases. The process gases are step-wise afterburned when ascending in the melting vessel by introducing the afterburn gases into the interior of the charge material column by way of an interior shaft that projects into the material column and in whose walls inlet openings for the gases are disposed and form afterburn planes arranged one on top of the other.

摘要： When aluminium products are preheated in a preheating furnace up to about 500° C. before they are brazed with a flux in a heating furnace, a nitrogen atmosphere in the preheating furnace is made convectional by fans for improving heating efficiencies and also for having the oxygen which is brought into the preheating furnace as a disturbance thereof and scattered about in the nitrogen atmosphere, contacted to furnace inner walls of the preheating furnace which are made from carbonaceous materials, and reacted therewith so as to be changed to CO, resulting in keeping the oxygen concentration of nitrogen atmosphere low, whereby when the aluminium products are brazed by heating them in a continuous atmosphere furnace including said preheating furnace and said heating furnace, heating time thereof is shorten and the brazing is made more economically than before.

摘要： The present invention relates to thermal reactions performed at rapid transient temperatures, and a furnace (1) able to perform such reactions. The method and the furnace may suitably be applied to perform reactions between reactants where significant losses normally occur at certain transient temperatures or temperature ranges. One practical application of the present invention relates to a carbothermic method for producing Refractory Hard Metal powders, such as borides, nitrides and carbides, and a furnace designed for the performance of the method. In accordance with this method Refractory Hard Metal powders, such as boride powders can be produced with reduced loss of reactants such as C and B2O3. This can be achieved by rapid heating of the mixture containing the reactants in a critical temperature range. For the performance of this particular embodiment a two-step furnace has been applied, where the temperature in each individual temperature zone (37, 38) Is respectively below and above critical temperatures of the reaction. In accordance with one embodiment of the present invention high purified boride, carbide and nitride powders with a fine grain size can be produced in a simple and cost effective manner.

摘要： The present invention provides a method and apparatus for controlling the fluid flow bias of continuous, multiple zone processes having gas or vapor comprising atmospheres that are in immediate access to each other. Active control of the fluid flow bias in at least one process zone or control of the overall process fluid flow bias is achieved by applying force to at least one of the zones of the process in a manner which enables such control. A physical or chemical property or a change thereof in at least one process atmosphere is monitored and an appropriate amount of force is applied in response to the monitored property. The monitored property is related to the furnace flow bias by an algorithm, so that the flow bias can be controlled by controlling the at least one chemical or physical property monitored.
