Sei Stainless Simbi zvinhu zvakaoma kugadzirisa?

Simbi isina simbi,   pakutanga yainzi rustless simbi, chero yeboka remaferrous alloys ane hushoma hunosvika 11% chromium, chimiro chinodzivirira simbi kubva kuita ngura uye zvakare inopa inodzivirira kupisa.

Kuenzaniswa nesimbi "yakapfava" yakaita sealuminium, simbi isina tsvina yakaoma kwazvo muchina. Izvi zvinodaro nekuti simbi isina simbi isimbi ine alloy ine simba guru uye purasitiki yakanaka. Munguva yekugadzira michina, zvinhu zvinova zvakaoma uye zvinogadzira kupisa kwakawanda. Izvi zvinotungamirira kukurumidza kucheka maturusi kupfeka. Heano pfupiso 6 zvikonzero zvikuru:

1. High tembiricha simba uye basa kuomesa tsika

Kana ichienzaniswa nesimbi yakajairika, simbi isina tsvina ine simba repakati nekuoma. Nekudaro, ine huwandu hukuru hwezvinhu zvakaita seCr, Ni, uye Mn, uye ine yakanaka plasticity uye kuoma, kusimba kwekushisa kwepamusoro, uye basa rakakwirira kuomesa maitiro izvo zvinokonzeresa mukutema mutoro. Mukuwedzera, mu austenitic simbi isina tsvina panguva yekucheka, imwe carbide inonaya mukati, iyo inowedzera kukwenya mhedzisiro pane cutter.

2.Simba guru rekucheka rinodiwa

Simbi isina tsvina ine hombe yepurasitiki deformation panguva yekucheka, kunyanya austenitic simbi isina tsvina (iyo elongation inodarika 1.5 nguva ye45 simbi), iyo inowedzera simba rekucheka.

3.Chip uye tool bonding phenomenon inowanzoitika

Zviri nyore kuumba mupendero wakavakirwa panguva yekucheka, iyo inokanganisa kushata kwepamusoro kwechigadzirwa chemichina uye nyore kukonzeresa pamusoro pechishandiso kuti chibvise.

4. Chipi chiri nyore kupeta uye kuputsa

Kune akavharwa uye semi-akavharwa chip cutters, chip clogging iri nyore kuitika, zvichikonzera kuwedzera kwepamusoro roughness uye tool chipping.

5. Iyo yakakura coefficient yekuwedzera kwemutsara

Inenge nguva imwe nehafu yemutsara wekuwedzera coefficient yecarbon steel. Pasi pechiito chekucheka tembiricha, iyo workpiece inotarisana nekupisa deformation uye inokanganisa dimensional kurongeka.

6. Diki thermal conductivity

Kazhinji, inenge 1/4 ~ 1/2 yekupisa kwekushisa kwepakati kabhoni simbi. Iyo tembiricha yekucheka yakakwira uye chishandiso chinopfeka nekukurumidza.

Nzira yekugadzira Stainless simbi?

Zvichienderana nemaitiro uye ruzivo rwedu, tinotenda kuti nhungamiro dzinotevera dzinofanirwa kutevedzwa pakugadzira simbi isina tsvina:

1.Kurapwa kwekupisa kusati kwagadzira, Maitirwo ekupisa anogona kushandura kuoma kwesimbi isina tsvina, zvichiita kuti muchina zvive nyore.

2.Kuzora kwakanaka, Mafuta anotonhodza ekuzora anogona kubvisa kupisa kwakawanda ozora pamusoro pechigadzirwa panguva imwe chete. Isu tinowanzo shandisa mafuta akasanganiswa anoumbwa nenitrogen tetrafluoride neoiri yeinjini. Kudzidzira kwakaratidza kuti lubricant iyi yakanyatsokodzera kugadzira simbi isina tsvina ine nzvimbo dzakatsetseka.

3.Shandisa zvemhando yepamusoro midziyo yekucheka kuti uwane nzvimbo dzakatsetseka uye zvidiki zvinoshivirira uku uchideredza nguva yekuchinja maturusi.

4.Lower kutema kukurumidza. Kusarudza yakaderera yekucheka kumhanya kunogona kuderedza kupisa chizvarwa uye kufambisa chip kutyoka.

Mhedziso

Zvese mune zvese, Stainless simbi ndechimwe chezvinhu zvakanyanya kuoma kumichina. Kana muchina chitoro ichikwanisa muchina aruminiyamu, mhangura, uye kabhoni simbi chaizvo, izvi hazvirevi kuti vanogona zvakare muchina Stainless simbi zvakanaka kwazvo.
