 Analysis on the use stage of well furnace There are several stages in the operation of a well furnace: Furnace installation, exhaust and temperature rise: 1, after the well furnace to the temperature insulation 0.5~1h, make the temperature uniform, into the parts, hanging parts should be more than 10mm gap, to ensure that the gas unblocked. 2, the parts must be placed in the effective heating zone of the furnace tank, the upper end should not exceed the exhaust pipe, the lower end should keep a certain distance from the intake pipe, after installing the furnace exhaust time is about 20~60min. 3. The sample should be placed in three different positions: upper, middle and lower. 4, after the installation of the furnace, should immediately send infiltration agent exhaust (ethanol drops), when the temperature of the furnace to the specified temperature, in the outlet of the exhaust gas, such as the flame does not point, should increase the amount of infiltration agent or time
