Abstract:
Es wird ein Verfahren und eine Vorrichtung vorgeschlagen, mit dem ein Fertigungsweg beschritten werden kann, in dem zunächst alle anfallenden Magnetkerne im Durchlauf kristallisiert werden. Je nach dem ob die geforderten Hystereschleifen nun rund, flach oder rechteckig sein sollen, werden diese Magnetkerne anschliessend entweder sofort endverarbeitet, d.h. in Gehäuse gefasst, in einem magnetischen Längsfeld auf eine rechteckige Hystereschleife oder in einem magnetischen Querfeld auf eine flache Hystereschleife umgetempert und erst dann Endverarbeitet.
Abstract:
The invention relates to a device for simultaneously tempering and processing several process goods by means of electromagnetic radiation. The device is a batch-type furnace. The process goods and the energy sources are arranged adjacent to each other in such a way that a process good is situated between two energy sources and an energy source is situated between two process goods. The device is especially useful for tempering the process goods in the presence of a process gas. A variable heating and cooling profile having variable processing parameters (e.g. gas pressure, heating rate, cooling rate) can be obtained using the inventive device. It is especially possible to securely temper a process good in the form of a large-surface multilayer body comprising layers of different physical characteristics (thermal conductivity coefficient, temperature expansion coefficient, absorption and emission capacity, etc.). According to the inventive method and device, a toxic and/or corrosive process gas can be used for processing the process good. The device and the method are useful for producing thin film solar modules for instance.
Abstract:
A control system (100) for heat-treating parts in a furnace structure (102) is provided. A plurality of processing chambers (106, 110, 112, 122, 124, 126, 128), each having at least one part position, are adapted to simultaneously process a plurality of parts each for a respective predetermined processing time. A memory device (184) stores first records representing processing times associated with each of the parts within each processing chamber, second records representing a desired processing path associated with each part through at least one processing chamber, and third records representing the number and location of occupied part positions within each processing chamber. A computerized control center (180) calculates desired processing times associated with at least one processing chamber for a new part to be processed in the processing chamber. Additionally, the computerized control center (180) determines an entrance time for the new part to enter the furnace structure (102), in response to the first, second, and third records, and to the calculated desired processing times.
Abstract:
Automatic automated installation for processing parts, designed in particular for the engineering industry where processing modules are being used, for example preheating modules, thermochemical processing modules and hardening modules. Said installation is used in heating, temperature-holding and controlled-cooling processes in order to preserve or improve surface condition, dimensional stability and metallurgical structure as well as the mechanical properties of the processed parts.
Abstract:
Изобретение относится к способам изготовления различных видов бытовых и промышленных чугунных изделий, в частности производству кухонной чугунной посуды для приготовления пищи. Способ изготовления чугунной посуды и других чугунных изделий, включает литье серого чугуна в литейную форму для получения отливки, механическую обработку отливки, включающую удаление литников, заусенцев, обдирку, шлифование, пескоструйную обработку отливки, и формирование на отливке защитного покрытия из окисного слоя железа путем ее нагрева и погружения в масло после нагрева. При формировании на отливке защитного покрытия из окисного слоя железа выполняют двукратный-четырехкратный нагрев отливки до температуры 570-800°С, погружение ее в масло после каждого нагрева и мойку после каждого погружения в масло. Технический результат: повышение коррозионной стойкости к агрессивным средам и увеличение срока службы.
