(1) the specimen in the porcelain boat should be leveled and the thickness of the sample should not be too large.High vacuum furnace used for brazing copper with better price
(2) when the ash could open the door, the heat board containing sample boat slowly advance the high temperature furnace box furnace, the samples in the boat slowly ashing smoke, no longer smoke to sample a few minutes later, the boat slowly into the hot part in high temperature furnace, close the door to the sample 815 + 15 burning. In the process of ashing, if the coal sample is burned and deflagrated, the coal sample must be reclaimed again.
(3) the furnace should have a chimney or ventilation hole to remove the combustion products and maintain the circulation of the air during the burning process.Energy saving Steel annealing electric furnace laboratory vacuum ovens
(4) the control system of the high temperature furnace must be instructed to be accurate. The temperature rise ability of a high temperature furnace must meet the requirement of ash determination.
(5) the ashing time should be able to ensure that the sample is completely ash at 815 + 15 temperature, but it is also unfavorable to prolong the ashing time at random.
