Little knowledge of vacuum sintering furnace

Vacuum sintering furnace in the furnace chamber within a particular space using vacuum system (by the vacuum pump, vacuum measuring device and vacuum valve components such as carefully) substances out of furnace cavity part, making furnace chamber pressure is less than a standard atmospheric pressure, so as to realize a vacuum furnace cavity space, that is the vacuum sintering furnace.
1) completely eliminates the oxidation and decarburization on the surface of the workpiece during the process of heating, clean surface without metamorphic layer can be obtained. That only when grinding mill side of cutting tools (such as twist drill grinding after make direct exposure to edge) of the decarburization layer of the grooved surface cutting performance greatly improved relations.
2) on the environment pollution-free, "three wastes" treatment is not required.
3) obviously improve the temperature measurement, the monitoring precision. Indicated value of thermocouple temperature and furnace temperature reached plus or minus 1.5 ° c. But in different parts of a large number of artifacts in the furnace temperature difference is bigger, if USES the rarefied gas forced circulation, can still be controlled within + / - 5 ° c temperature difference.
4) high degree of mechanical and electrical integration. Increase in the temperature measurement and control accuracy, on the basis of the workpiece moving, pressure adjustment, power adjustment, etc all can set programming in advance, according to the steps to implement the quenching and tempering. 5) energy consumption significantly below the salt bath furnace. Modern advanced vacuum furnace heating chamber is made of high quality insulation material of insulation walls and barriers, electric energy can be highly focused on indoor heating, energy saving effect is remarkable.
