The working principle of the vacuum tube type experimental electric furnace is: the use of quartz or corundum tube as a sealed container, the choice of stainless steel sealing flange, so that the quartz or corundum tube to meet the conditions of sealing, at the same time can be very convenient to take the experimental materials.
When using the vacuum tube type experimental furnace, simply put the experimental material into the quartz tube or corundum tube, seal the quartz tube or corundum tube through the stainless steel flange, through the vacuum pump or flange on the reserved air inlet, extract the quartz tube or corundum tube gas or pass into the specific atmosphere, in the quartz tube or corundum tube heating to meet the requirements of the experiment.
Vacuum tube type experimental furnace in the atmosphere, it is recommended that the first pre-pumping vacuum, and then into the corresponding atmosphere, such as conditions allow, it is best to repeat several times, so that in the experiment, high temperature furnace tube atmosphere will be higher purity.
ndustrial furnaces are used globally for a wide range of applications. As the selection of applications grew, different types of furnaces were developed to keep up with demands.
Ashing furnaces are used to determine the amount of ash that forms after a sample is burned. Typical materials used as samples in ashing furnaces are petroleum products, lubricating oils, and coal.
