Kubva pakuumbwa kusvika kune chimiro, huwandu hwezvinhu zvinokanganisa maitiro ezvigadzirwa zvesimbi isina tsvina.Imwe yezvinonyanya kukosha ndeye giredhi resimbi yekushandisa.Izvi zvinosarudza huwandu hwehunhu uye, pakupedzisira, zvese mutengo uye hupenyu hwezvigadzirwa zvako zvesimbi isina tsvina.
Saka unoziva sei pekutangira?
Kunyange chishandiso chega chega chakasarudzika, iyi mibvunzo minomwe inosimbisa kufunga kwakakosha kuti ikubatsire kudzikisa sarudzo dzako uye kuwana mamakisi anonyatsokodzera zvaunoda kana mashandisiro ako.
1. NDERUPI RUDZIDZO RWOKUPIRWA INODA simbi yangu?
Paunofunga nezvesimbi isina tsvina, zvinhu zvekutanga zvinouya mupfungwa zvinogona kuramba kune acids nema chlorides-seaya anowanikwa mumaindasitiri ekushandisa kana nharaunda dzemugungwa.Zvisinei, kuramba tembiricha chinhu chinokosha kufunga zvakare.
Kana iwe uchida kusagadzikana kwekuora, iwe unoda kudzivisa ferritic uye martensitic steels.Yakanaka Stainless simbi mamakisi enzvimbo dzinoparadza anosanganisira austenitic kana duplex alloys akadai mamakisi 304, 304L, 316, 316L, 2205, uye 904L.
Kune nzvimbo dzepamusoro-tembiricha, austenitic mamakisi anowanzo akanakisa.Kuwana giredhi rine high chromium, silicon, nitrogen, uye zvisingawanzo zvinhu zvepasi zvichawedzera kushandura kugona kwesimbi kushingirira tembiricha yakakwira.Magiredhi akajairwa enzvimbo dzepamusoro-tembiricha anosanganisira 310, S30815, uye 446.
Austenitic simbi mamakisi zvakare akanakira yakaderera-tembiricha kana cryogenic nharaunda.Kuti uwedzere kuramba, unogona kutarisa yakaderera kabhoni kana yakakwirira nitrogen mamakisi.Magiredhi akajairwa enzvimbo dzakaderera-tembiricha anosanganisira 304, 304LN, 310, 316, uye 904L.
2. SIMBA YANGU INOFANIRA KUUMBIKA HERE?
Simbi isina kuumbwa zvakanaka inogomara kana ikashandwa zvakanyanya uye ichipa kuita kwakaderera.Muzviitiko zvakawanda, martensitic steels hazvikurudzirwi.Uyezve, simbi ine yakaderera kuumbwa inogona kusachengeta chimiro chayo kana yakaoma kana yakaoma kuumba ichidikanwa.
Paunenge uchisarudza giredhi resimbi, iwe uchada kufunga nezve fomu yaungade kuti iunzwe.Kunyangwe iwe uchida tsvimbo, slabs, mabara kana mashiti zvinomisa sarudzo dzako.Semuenzaniso, ferritic steels dzinowanzotengeswa mumashizha, martensitic steels anowanzotengeswa mumabhawa kana slabs, uye austentic steels inowanikwa mumhando yakawanda yemafomu.Mamwe mamakisi esimbi anowanikwa mune akasiyana mafomu anosanganisira 304, 316, 430, 2205, uye 3CR12.
3. SIMBA YANGU INODA KUCHENGA HERE?
Machining harisi dambudziko.Zvisinei, kuomesa basa kunogona kuunza migumisiro isingatarisirwi.Kuwedzerwa kwesarufa kunogona kuvandudza machinability asi kunoderedza kuumbwa, weldability uye kusagadzikana kwekuora.
Izvi zvinoita kuti kuwana chiyero pakati pemachinability uye corrosion kuramba ikoshe kutarisisa kune akawanda mastage stainless stainless simbi yekugadzira maitiro.Zvichienderana nezvaunoda, mamakisi 303, 416, 430, uye 3CR12 anopa mwero wakanaka kubva paupfure sarudzo mberi.
4. NDOFANIRA KUSVIRWA HERE YANGU INOSINA?
Welding simbi isina tsvina inogona kutungamirira kumatambudziko-kusanganisira kupisa kunopisa, kushungurudzika kuora kwekuputika, uye intergranular corrosion-zvichienderana negiredhi resimbi inoshandiswa.Kana iwe ukaronga weld yako Stainless simbi, austenitic alloys akanaka.
Low kabhoni mamakisi anogona kuenderera mberi nekubatsira nekushivirira nepo zvinowedzerwa, senge niobium, zvinogona kudzikamisa alloys kudzivirira kushushikana kwekuora.Akakurumbira mamakisi eStainless simbi yewelding anosanganisira 304L, 316, 347, 430, 439 uye 3CR12.
5. ZVINODZORERA ZVINODA HERE?
Kana chikumbiro chako chichida kurapwa kwekupisa, unofanirwa kufunga kuti magiredhi akasiyana esimbi anopindura sei.Mamiriro ekupedzisira emamwe masimbi akasiyana zvakanyanya pamberi uye mushure mekupisa kurapwa.
Kazhinji, martensitic uye kunaya kwemvura inoomesa simbi, senge 440C kana 17-4 PH, inopa mashandiro epamusoro kana kupisa kwakarapwa.Mazhinji austenitic uye ferritic Stainless steels haaomese kana kupisa kwaitwa uye saka haisi yakanaka sarudzo.
6. NDEIPI SIMBA RESIMBA RINOKANIRA KUSHANDISA KWANGU?
Simba resimbi chinhu chakakosha kufunga kuti uwedzere kuchengeteka.Asi, kubhadharisa zvakanyanya kunogona kutungamirira kumutengo usingadikanwi, uremu, uye zvimwe zvinhu zvinopambadza.Simba hunhu hwakaiswa zvakasununguka nemhuri yesimbi ine mamwe misiyano inowanikwa mumagiredhi akasiyana.
7. CHII CHINOITWA UPFRONT COST AND LIFETIME COST YESTEEL IN MY SCENARIO?
Zvose zvakafungidzirwa zvakapfuura zvinodyisa mumubvunzo unonyanya kukosha pakusarudza giredhi resimbi isina tsvina-yeupenyu mari.Kufananidza mamakisi esimbi isina simbi kune yako yaunoda nharaunda, mashandisiro uye zvinodiwa, unogona kuve nechokwadi chekuita kwenguva refu uye kukosha kwakasarudzika.
Chenjerera kuongorora kuti simbi ichaita sei panguva yakatarwa yekushandiswa uye kuti ndezvipi zvinodhura zvingave zvakabatanidzwa mukugadzirisa kana kutsiva usati wasarudza.Kudzikamisa mitengo kumberi kunogona kukonzera kushandiswa kwakawanda pamusoro pehupenyu hweprojekiti yako, chigadzirwa, chimiro, kana imwe application.
Nehuwandu hwakawandisa hwemagiredhi esimbi isina simbi uye mafomu aripo, kuva nenyanzvi yekubatsira kuratidza sarudzo uye dzingangove makomba inzira yakanaka yekuona kuti uri kuwana kukosha kwakaringana kwekudyara kwesimbi isina simbi.Semutungamiri anotungamira wesimbi isina simbi kweanopfuura makore makumi maviri, Jindalai Steel Group inokwirisa ruzivo rwedu kuti ikubatsire kukutungamira munzira yekutenga.Wona yedu yakakura runyorwa rwezvigadzirwa zvisina tsvina pamhepo kana kufona kuti ukurukure zvaunoda nenhengo yechikwata chedu.
