What are the main measures to improve the vacuum of vacuum furnaces?

      There are two ways to increase the system temperature difference during the evaporation of the vacuum furnace: one is to increase the heating steam pressure, and the other is to increase the final vacuum. However, the pressure of the heating steam will increase the temperature of the subsequent effect, and the increase in production capacity is not obvious. On the contrary, it can lead to problems such as scaling, shortened operating cycles, and increased equipment corrosion. Therefore, increasing the vacuum is a better choice to increase the total temperature difference of the system.

      In recent years, manufacturers of high-temperature vacuum furnaces have adopted a new type of atmospheric cooler to replace the traditional cooler, and achieved good results. In fact, the new cooler uses nozzles instead of spray plates. The cooling water forms water mist through nozzles distributed in the cooler, which greatly increases the vapor-liquid contact area between the cooling water and the secondary steam, improves the utilization efficiency of the cooling water, and achieves a higher vacuum in the vacuum furnace. Experiments show that the vacuum formed by the condenser is more than 2000 Pa higher than that of the traditional water jet plate cooler.

       The vacuum sintering furnace is a furnace used for protective sintering of heated objects in a vacuum environment. There are many heating methods, such as resistance heating, microwave heating, induction heating and so on. Vacuum induction furnace is a kind of furnace that uses induction heating to protect heated articles. It can be divided into power frequency, intermediate frequency, high frequency and other types, and can be divided into sub-categories of vacuum sintering furnace.

       The vacuum sintering furnace can meet the process requirements of rapid heating. The temperature control switch is controlled by an imported multi-level intelligent program Celsius controller. The stability and repeatability of the Celsius controller is very reliable. Frequency conversion stepless speed regulation, stainless steel mesh belt transmission and brand-new appearance design concept ensure the smooth transportation of products.

       The vacuum sintering furnace uses the principle of intermediate frequency induction heating to make the tungsten crucible in the coil generate high temperature, which is conducted to the workpiece through thermal radiation. Suitable for powder forming and sintering of refractory alloys such as tungsten, molybdenum and their alloys by scientific research and military units
