用途：

适用于工模具、高速钢、不锈钢等材料的无氧化回火。 It is suitable for non oxidation tempering of tools and dies, high speed steel, stainless steel and other material

特点：

（对比井式：无需挖坑，同时适合同样温度回火的工件从真空炉出来无需转换料框，可节约人工） 1 安全性高（压力达到设定值自动排放，同时减少人工操作的风险隐患） 2 炉温均匀性好（普遍控制在±2度） 3 稳定性好（配件均采用可靠稳定供应商，同时加装水路检测，减少了风机以及密封条的受热损坏问题） 4 节能（采用优质耐火材料，同时加厚了保温层） 5 手动/自动控制（PLC自动化控制） (contrast well type: no need to dig a pit, and it is suitable for the workpiece tempered at the same temperature to come out of the vacuum furnace without changing  the material frame, which can save manpower) 1. High safety (automatic discharge when the pressure reaches the set value and reduces the risk of manual operation) 2 furnace temperature uniformity is good (generally controlled within ± 2 degrees) 3. Good stability (all accessories are supplied by reliable and stable suppliers. At the same time, waterway detection is added to reduce the thermal damage of fans  ａnd sealing strips) 4 energy saving (using high quality refractory material and thickening the insulation layer) 5 manual / automatic control (PLC automatic control)
