Three details that are easy to ignore when using a box type resistance furnace 1. When using a box-type resistance furnace to heat the workpiece, no setter plate is added: the box-type resistance furnace manufacturer has equipped a corresponding size setter plate for each box-type resistance furnace. All heating workpieces, including the container for the workpiece, should be placed Heat on the setter plate. Try to avoid placing the ceramic fiberboard directly at the bottom of the furnace, which will cause uneven stress on the fiberboard or high local temperature, which will damage the bottom of the box-type resistance furnace.HORIZONTAL MITRE BAND SAW MACHINE BS-215G 2. Want the box-type resistance furnace to cool down quickly, and open the furnace door when the temperature is high: Because the box-type resistance furnace has a very good insulation effect, the energy consumption during insulation is very low, and the temperature drops very slowly after the power supply is stopped.HORIZONTAL MITRE BAND SAW MACHINE BS-260G Some customers hope that the next experiment can be carried out immediately after one experiment is completed, so they open the furnace door at high temperature to obtain a high cooling rate, but this will cause great damage to the furnace chamber of the box-type resistance furnace, and it is easy to cause a cold and a hot. The furnace is cracked, and the heating element of the box-type resistance furnace cannot withstand such a thermal shock.Heat treatment process of gear vacuum carburizing and quenching We generally recommend that the box-type resistance furnace is at least cooled to 600 ℃ before carefully opening the furnace door a little. If high temperature pick and place parts are indeed required, consideration should be given to whether a silicon carbide furnace can be used. 3. Do not bake the oven when it is used after a long shutdown: This is also a detail that is easy to ignore. Basically, all customers can do the oven when the box-type resistance furnace muffle furnace is used for the first time, but many customers will Forget the oven when it is used again after a shutdown of more than a week.
