Description: Das Projekt "Bogie hearth Annealing Furnace" wird vom Umweltbundesamt gefördert und von STAMA Hahne Stahl- und Maschinenbaugesellschaft GmbH durchgeführt. Objective: The steel processing industry necessitates a thermical treatment of constructions in form of welded constructions, cast steel constructions or a combination of both. The applied heat treatments are stress relieving, tempering, solution heat treatment and normalizing just to mention the most important ones. All procedures have in common the annealing of the construction to a certain temperature, holding the temperature for a certain amount of time and the subsequent cooling to room temperature. The energy hereby used is mostly natural gas or mineral oil transformed into heat which in a later stage is lost to the atmosphere. This is where the following project comes in: Our aim was to considerably reduce the amount of energy used by the help of novel isolation material, optimized gas burners and a precise temperature regulating system. The theoretical reflections had shown that energy could be saved up to an amount of 50 per cent compared with conventional installations. General Information: The furnace designed by STAMA is a boogie furnace. This means that the load to be annealed is placed on a trolley which is then pushed into the interior of the furnace. A door in the front shuts the furnace completely. The heating up is supplied by burners which are installed inside the furnace. The switching on/off of the burners initiated by the computerized control system guarantees a regular flow of the temperature. The necessary information for the control system is supplied by thermo elements arranged in the interior of the furnace. The carrier of the furnace consists of a steel construction with profiles. Rolled steel plates cover the construction at the surface of the furnace. Moving now to the inside of the furnace: Along both sides of the steel construction starting at the height of the edge of the trolley up to approx. half of the height of the construction recesses from the chambers for the burners. In the ceiling of these chambers the burners are vertically arranged. The door of the furnace is fitted at the front and consists of two parts, namely two frames formed by hot rolled channels with rounded edges and covered by rolled steel plates on the front. The inside walls, the ceiling/the inside of the door is isolated by multi-layer ceramic fibres. The trolley forms the ground of the furnace. It consists of a frame construction with seven axels with two wheels each. The axels are the same as the ones used by the railway. The top of the trolley consists of fire-proof cement resistent to high pressure. Opposite the interior of the furnace the lower side of the trolley is isolated by a labyrinth filled with sand. In the ceiling of the furnace there are six chimneys. They serve as a valve during the process of firing and remain open during the process of cooling. With the help of pneumatic positioning the control system regulates the opening/closure of the chimney flaps. The control system consists of eight regulators...
