The influencing factors of vacuum furnace temperature to transfer

1, the strength of the vacuum furnace heating element, in the design, mainly in the form of heat. Internal heat source heating, temperature, from inside to outside, the strength size directly affect the temperature distribution in the furnace. When the inner court, the higher, the higher the temperature of the a fixed-point, at the same time must be the bigger the temperature difference distribution area. So, in the actual production process, can control the surface of the furnace core through the load or furnace core power control furnace temperature distribution.
2, reaction material from the core of distance, when furnace core power must have, namely the strength of the internal heating element must have, the farther distance furnace core of reaction, the lower the temperature, may not be able to achieve the required temperature reaction, the closer distance furnace core, the higher the temperature, the reaction.
3, burden the better performance of radiator cooling performance of the furnace charge, internal heat loss, the faster the outward heat loss in the reaction of material very easily, cause a fixed temperature decrease. But if the cooling performance of the reaction is not good, is needed for the convergence of heat, allows heat to pass time lengthen, conducive to the material to absorb heat and reaction, raise the temperature of a fixed point. Reaction under the condition of high vacuum (pa) 4 ~ 13, reaction temperature 1200 ℃, temperature of furnace core will soon be able to achieve the required value, so the reaction time of depending on the thickness of the material, the reaction furnace core periphery thought furnace insulation layer in the distance. Can through the design of furnace size control power supply time.
