3. 裝爐量大、加工成本低

The charging capacity is large and the processing cost is low.
采用真空脈沖變壓技術，在低真空和變壓的環境下完成滲氮（氮化）工藝過程，新鮮氣氛可滲透到爐罐內任一角落，所以工件可以密裝，使裝爐量大大增加，同時，該爐密封性，保溫性能好，從而顯著降低處理成本

Vacuum pulse pressure conversion technology is used to complete nitriding (nitriding) process in low vacuum and pressure changing environment. The fresh atmosphere can penetrate into any corner of the furnace tank, so the workpiece can be packed closely, which greatly increases the charging capacity. At the same time, the furnace has good sealing and heat preservation performance, thus significantly reducing the treatment cost.
