Selection of resistance furnace
According to the resistance furnace chamber material selection
1, the traditional furnace is brick structure, this furnace is better fire resistance performance, and the price is relatively appropriate;
2, ceramic fiber furnace structure, aluminum silicate ceramic fiber furnace is the traditional furnace upgrade products, with light weight, fast speed, energy saving, time-saving characteristics, can meet the requirements of various rapid sintering. And can be configured with 30 program temperature control instrument, is a relatively high cost performance.
According to the resistance furnace chamber temperature selection
According to the user's operating temperature to choose the appropriate resistance furnace, but to distinguish between the design temperature and operating temperature. If using temperature is 1000, for example, you can choose the design temperature for 1200 electric resistance furnace, because although there is a resistance furnace chamber of a stove or furnace design temperature for 1000, but its temperature does not reach 1000, so if choose the resistance furnace with 1000, cannot meet the use requirements, and can greatly reduce the service life of electric resistance furnace.
Select according to the furnace size of resistance furnace
Size selection is easier because the best size can be chosen to accommodate the object to be hardened.
According to the resistance furnace type structure to choose
1, integrated box type resistance furnace. This kind of resistance furnace is the temperature control instrument and furnace body design as a whole, easy to install and operate users;
2, split type resistance furnace. Split type resistance furnace is the temperature control instrument and furnace body separation, the need to install the temperature control instrument on the furnace body before the next step of installation and use, but the price of split type resistance furnace compared to the integrated resistance furnace is a lot cheaper, is the most advantageous price of a choice.
Of course, the selection of resistance furnace is in addition to these focus, should also be integrated with other factors to consider.
