1. Ukubhaqwa kwemagnethi

Uthe intsimbi engenastainless yimagnethi, akunjalo! Kukwayinyaniso ukuba ayikho magnetic! Enyanisweni, zahlukile. Sonke siyazi ukuba insimbi engenasici yahlulwe yaba yintsimbi ye-austenitic kunye ne-ferritic stainless steel. I-Austenitic stainless steel ayiyo-magnetic, ngelixa i-ferritic stainless steel iyintsimbi eyomeleleyo enozibuthe. Ngothotho lweemvavanyo, kungqinwa ukuba i-austenitic stainless steel iya kuba nemagnethi efihlakeleyo phantsi kweemeko ezithile ezikhethekileyo, kodwa ayinamagnetic phantsi kweemeko eziqhelekileyo.

2. Yenza uvavanyo lwe-nitric acid point

Kwiimeko ezininzi, kunzima ukuhlukanisa uchungechunge lwama-200, uchungechunge lwe-300, uchungechunge lwe-400 kunye nezinye iintlobo zensimbi engenasici ngeso lenyama. Uvavanyo lwe-nitric acid point yeyona ndlela yokuvavanya enembileyo yokuvavanya ukuxhathisa kokutya kwe-substrate. Ngokuqhelekileyo, uchungechunge lwe-400 luya kutshatyalaliswa kancinci ngexesha lovavanyo, ngelixa uchungechunge lwe-200 yensimbi engenasici kunye neyona nto iphantsi yokumelana ne-corrosion iya kuba neempawu ezicacileyo zokubola.

3. Uvavanyo lokuqina

Ukuba i-austenitic stainless steel iya kubonisa i-magnetism ethile xa ibanda iqengqeleka phantsi koxinzelelo lwe-atmospheric, ngoko uvavanyo lokuqala lwemagnethi olukhankanywe alusebenzi; ngoko ke kufuneka sifudumeze intsimbi engatyiwayo malunga ne-1000-1100 ℃ kwaye emva koko siyicime ngamanzi ukuze kupheliswe imagnethi yentsimbi engenasici kunye nokuvavanya ubulukhuni. Ubunzima bentsimbi ye-austenitic stainless ngokuqhelekileyo bungaphantsi kwe-RB85

Ukwengeza

Ukuqina kwe-430, 430F kunye ne-466 yentsimbi ingaphantsi kwe-Rc 24

Ubunzima be-410, 414, 416 kunye ne-431 yi-Rc36 ~ 43

Ukuqina kwekhabhoni ephezulu 420, 420F, 440A, B, C kunye nentsimbi ye-F yiRc50 ~ 60

Ukuba ubunzima yiRc50 ~ 55, ingaba yintsimbi ye-420

Ubunzima beesampuli ze-440A kunye ne-B ezicinyiweyo yi-Rc55 ~ 60

Ixabiso le-Rc le-60 okanye ngaphezulu liyintsimbi ye-440C.

4. Ngokuhlola oomatshini

Ukuba insimbi engenasici ivavanywayo i-shaft-shaped, kucetyiswa ukuba uyithathe kwi-lathe eqhelekileyo okanye i-CNC lathe yokuhlola umatshini, kodwa kusekho imida. Le ndlela ifaneleka kuphela kwintsimbi elula yokusika kunye nentsimbi eqhelekileyo, njenge-303, 416, 420F, 430F, 440F. Uhlobo lwentsimbi luchongwa ngokubunjwa kwee-chips eziguqukayo. Olu hlobo lwentsimbi olulula ukusika luya kukhupha iphunga elingathandekiyo xa liguqulelwe kwimeko eyomileyo.

5. Ukufunyanwa kwe-asidi ye-phosphoric

Le yindlela yokufumanisa esiyisebenzisa rhoqo kubomi bemihla ngemihla. Le ndlela isetyenziselwa ukwahlula i-chromium-nickel yensimbi engenasici. Yongeza i-phosphoric acid egxininisiweyo kwi-0.5% yesisombululo se-sodium fluoride kwaye uyifudumeze ukuya kwi-60-66℃.

6. Ukufunyanwa ngendawo ye-copper sulfate

Le ndlela inokubhaqa intsimbi yekhabhoni eqhelekileyo kunye nentsimbi engenasici. Ukuxinwa kwesisombululo se-copper sulfate kufuneka kube phakathi kwe-5% kunye ne-10%. Xa uwiswe kwintsimbi ukuba ihlolwe, i-metallic copper iya kubumba phezu kwe-carbon steel eqhelekileyo kwimizuzwana embalwa, ngelixa i-stainless steel stainless iya kuhlala ingatshintshi.

7. Ukufumanisa isisombululo se-Sulfuric acid

Le ndlela inokwahlula i-302, i-304, i-316, kunye ne-317 yeentsimbi ezingenasici. Lungisa i-asidi ye-sulfuric kunye ne-concentration ye-20% ukuya kwi-30% kunye neqondo lokushisa malunga ne-70 ° C, kwaye ubeke intsimbi ukuba ihlolwe kwisisombululo. I-302 kunye ne-304 i-stainless steels iya kuvelisa inani elikhulu leebhubhu xa zidibana nesisombululo kwaye ziya kuba mnyama kwimizuzu embalwa;

Ngokuchasene noko, i-316 kunye ne-317 i-stainless steels ayiyi kubonisa ukusabela okukhulu kwisisombululo, kwaye ngokusisiseko ayiyi kuba mnyama ngaphakathi kwe-10 ukuya kwi-15 imizuzu.

8. Ukubona indawo ye-asidi ebandayo

Uhlobo olufanayo lwensimbi engenasici lunokwahlulwa ngokuvuza isisombululo se-asidi ye-sulfuric engama-20% kumphezulu wesampulu ephantsi, epholisiweyo, ecociweyo okanye epholileyo.

Lahla amathontsi ambalwa esisombululo seasidi kumphezulu wesampulu nganye. Ngaphantsi kwesenzo sesisombululo se-asidi, i-302 kunye ne-304 i-stainless steels i-corrod kakhulu kwaye ijika ibe mnyama, ibonisa i-brown-black okanye i-black, kwaye emva koko iikristale eziluhlaza zenziwe kwisisombululo;

I-316 intsimbi engatyiwayo idla ngokucotha kwaye ngokuthe ngcembe ijike ibe mdaka-mthubi, emva koko ijike ibe mdaka-mnyama, kwaye ekugqibeleni yenze iikristale ezimnyama ezikhanyayo kwisisombululo; Ukusabela okungasentla kwe-317 yensimbi engenasici kuhamba kancinci.

9. Ukuqwalasela ngeentlantsi

Uvavanyo lwe-spark lusetyenziselwa ukwahlula i-carbon steel, i-alloy ye-structural alloy steel kunye ne-steel yesixhobo, kodwa ayisebenzi kangako ekuhlukaniseni insimbi engenasici. Le ndlela yokuvavanya i-spark inokunceda abaqhubi abanamava ukuba bahlele isinyithi esingenasici kwiindidi ezine ezinkulu, kodwa akukho lula ukwahlula phakathi kwamanqanaba entsimbi ahlukeneyo.

Iimpawu ze-spark ezibonisa ezi ndidi zine zoomatshini bensimbi engenasici zimi ngolu hlobo lulandelayo:

Iklasi A: 302, 303, 316 intsimbi, ukuvelisa iintlantsi ezibomvu ezimfutshane kunye neefolokhwe ezininzi.

Iklasi B: 308, 309, 310 kunye ne-446 intsimbi, ivelisa iintlantsi ezimbalwa ezimfutshane ezibomvu ezimnyama ezinefolokhwe ezininzi.

I-Class C: 410, 414, 416, 430 kunye ne-431 yentsimbi, ivelisa iintlantsi ezimhlophe ezinde kunye neefolokhwe ezininzi.

Iklasi D: 420, 420F kunye ne-440A, B, C, F, ivelisa iintlantsi ezinombala omenyezelayo ezinokukhanya okucacileyo okanye iintlantsi ezinde ezimhlophe.

10. Ngokubona i-hydrochloric acid

Le ndlela yokufumanisa inokwahlula i-403, 410, 416, 420 insimbi engenasici enomxholo ophantsi wechromium ukusuka kwi-430, 431, 440, 446 insimbi engenasici enomxholo ophezulu we-chromium.

Dissolve iimali ezilinganayo zokusikwa kwesampula kwisisombululo se-hydrochloric acid kunye nomthamo we-volume ye-50% malunga nemizuzu emithathu, kwaye uthelekise ubunzulu bombala wesisombululo. Intsimbi enomxholo ophezulu wechromium inombala oluhlaza omnyama.
