可控氣氛氣體氮化爐+后氧化爐

應(yīng)用結(jié)構(gòu)；臥式箱式/立式箱式

Application structure; horizontal / vertical box type; horizontal box type / vertical box type

主要供各種鋼制機械零件、汽車配件，模具材料進行滲氮、氮化+后氧化，氮碳共滲、前氧化、后氧化、氧氮共滲等多種熱處理工藝之用.

It is mainly used for nitriding, nitriding post-oxidation, nitrocarburizing, pre-oxidation, post-oxidation, oxygen-nitriding and other heat treatment processes for various steel mechanical parts, auto parts and die materials.。

1. 特征 /characteristic
（NA-C）工藝是在低真空狀態(tài)下進行爐內(nèi)壓力周期式變化，氣氛保持新鮮、活性，氮勢也呈周期式變化，氮化結(jié)束沖入水蒸氣形成的氧化層，白亮層，擴散層的復(fù)合結(jié)構(gòu)

(NA-C) the process is to carry on the pressure periodic change in the furnace under the condition of low vacuum, the atmosphere keeps fresh, the activity, the nitrogen potential also shows the periodic change, the nitriding ends to wash into the oxide layer formed by water vapor, the white layer, the diffusion layer composite structure.
2. 工藝適應(yīng)性廣、設(shè)備先進 /wide process adaptability and advanced equipment
適用于高中低碳鋼，合金鋼，鑄鐵，球鐵，灰鐵，不銹鋼表面強化處理，適用于耐腐蝕，耐磨環(huán)境（油田，化工，汽車，高鐵工業(yè)環(huán)境與不粘鍋等家用產(chǎn)品），經(jīng)過處理耐腐蝕性能超過不銹鋼，耐磨性超過普通氮化，經(jīng)過后氧化處理的產(chǎn)品，鹽霧試驗達到360h以上,可替代鍍鋅，鍍絡(luò)，發(fā)黑，工藝環(huán)保無污染

Suitable for high and medium carbon steel, alloy steel, cast iron, ductile iron, gray iron, stainless steel surface strengthening treatment, suitable for corrosion resistance, wear resistance environment (oil field, chemical industry, automobile, high iron industrial environment and non-stick pot and other household products). After treatment, corrosion resistance exceeds stainless steel, wear resistance exceeds ordinary nitriding, salt spray test up to 360 h, can replace galvanizing, complexing, blackening, Process environmental protection without pollution。

該設(shè)備適用于盲孔、長孔，夾縫等復(fù)雜形狀，氮化爐真空脈沖變壓技術(shù)使?fàn)t內(nèi)氣氛自動擴散到罐內(nèi)各處，無死角。盲孔、毛孔及模具狹縫處工作面也能得到所需滲層

The equipment is suitable for blind hole, long hole, crack and other complex shapes. The vacuum pulse pressure conversion technology of nitriding furnace makes the atmosphere in the furnace automatically spread to all parts of the tank without dead angle. The required seepage layer can also be obtained in the working face at the blind hole, pore and die slit.
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(shù)，在低真空和變壓的環(huán)境下完成滲氮（氮化）工藝過程，新鮮氣氛可滲透到爐罐內(nèi)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.
