Applicationstructure; horizontal / vertical box type; horizontal box type / vertical boxtype
主要供各种钢制机械零件、汽车配件，模具材料进行渗氮、氮化+后氧化，氮碳共渗、前氧化、后氧化、氧氮共渗等多种热处理工艺之用.
Itis mainly used for nitriding, nitriding post-oxidation, nitrocarburizing,pre-oxidation, post-oxidation, oxygen-nitriding and other heat treatmentprocesses for various steel mechanical parts,
auto parts and die materials.。
1. 特征 /characteristic
（NA-C）工艺是在低真空状态下进行炉内压力周期式变化，气氛保持新鲜、活性，氮势也呈周期式变化，氮化结束冲入水蒸气形成的氧化层，白亮层，扩散层的复合结构
(NA-C)the process is to carry on the pressure periodic change in the furnace underthe condition of low vacuum, the atmosphere keeps fresh, the activity, thenitrogen potential also shows the periodic
change, the nitriding ends to washinto the oxide layer formed by water vapor, the white layer, the diffusionlayer composite structure.
2. 工艺适应性广、设备先进 /wideprocess adaptability and advanced equipment
适用于高中低碳钢，合金钢，铸铁，球铁，灰铁，不锈钢表面强化处理，适用于耐腐蚀，耐磨环境（油田，化工，汽车，高铁工业环境与不粘锅等家用产品），经过处理耐腐蚀性能超过不锈钢，耐磨性超过普通氮化，经过后氧化处理的产品，盐雾试验达到360h以上,可替代镀锌，镀络，发黑，工艺环保无污染
Suitablefor high and medium carbon steel, alloy steel, cast iron, ductile iron, grayiron, stainless steel surface strengthening treatment, suitable for corrosionresistance, wear resistance environment
(oil field, chemical industry,automobile, high iron industrial environment and non-stick pot and otherhousehold products). After treatment, corrosion resistance exceeds stainlesssteel, wear resistance exceeds ordinary nitriding, salt spray test up to 360 h,can
replace galvanizing, complexing, blackening, Process environmentalprotection without pollution。
该设备适用于盲孔、长孔，夹缝等复杂形状，氮化炉真空脉冲变压技术使炉内气氛自动扩散到罐内各处，无死角。盲孔、毛孔及模具狭缝处工作面也能得到所需渗层
Theequipment is suitable for blind hole, long hole, crack and other complexshapes. The vacuum pulse pressure conversion technology of nitriding furnacemakes the atmosphere in the furnace automatically
spread to all parts of thetank without dead angle. The required seepage layer can also be obtained in theworking face at the blind hole, pore and die slit.
3. 装炉量大、加工成本低
Thecharging capacity is large and the processing cost is low.
采用真空脉冲变压技术，在低真空和变压的环境下完成渗氮（氮化）工艺过程，新鲜气氛可渗透到炉罐内任一角落，所以工件可以密装，使装炉量大大增加，同时，该炉密封性，保温性能好，从而显著降低处理成本
Vacuum pulse pressureconversion technology is used to complete nitriding (nitriding) process in lowvacuum and pressure changing environment. The fresh atmosphere can penetrateinto any corner of the
furnace tank, so the workpiece can be packed closely,which greatly increases the charging capacity. At the same time, the furnacehas good sealing and heat preservation performance, thus significantly reducingthe treatment cost.
