The oxidation and decarburization of the workpiece surface during the heating process are completely eliminated, and a clean surface without a metamorphic layer can be obtained. This is a great improvement in cutting performance for those tools that only grind one side during sharpening (such as twist drills that expose the decarburized layer on the groove surface directly to the cutting edge after grinding).
get solutionEquipment for heating in a vacuum environment. In the furnace chamber sealed by metal casing or quartz glass casing, it is connected with the high vacuum pump system by pipeline. The vacuum degree of the furnace can reach 133×(10-2~10-4)Pa. The heating system in the furnace can be directly heated by electric resistance furnace wire (such as tungsten wire), or can be heated by high frequency induction.
get solutionThe energy consumption is significantly lower than that of a salt bath furnace. The modern advanced vacuum furnace heating chamber adopts thermal insulation walls and barriers made of high-quality thermal insulation materials, which can highly concentrate the electric heating energy in the heating chamber, and the energy saving effect is remarkable.
get solutionIn a vacuum state, a group of welding parts are heated to a temperature above the melting point of the filler metal, but lower than the melting point of the base metal, and a welding process is formed by means of the wetting and flow of the filler metal to the base metal (brazing temperature due to materials vary).
get solutionHigh degree of mechatronics. On the basis of improving the accuracy of temperature measurement and control, workpiece movement, air pressure adjustment, power adjustment, etc. can be programmed in advance, and quenching and tempering can be implemented in steps
get solutionIn order to prevent the deformation of the furnace shell and the deterioration of the sealing material after heating, the furnace shell is generally cooled by water or air. The furnace is located in a sealed furnace shell. According to the purpose of the furnace, different types of heating elements are installed inside the furnace, such as resistance, induction coil, electrode and electron gun, etc.
