Pfungwa, hunhu uye mwero wekugadzirwa kwe304 high-strength usahihi wesimbi isina tsvina

304Mutsetse wesimbi isina ngura wakasimba kwazvo chigadzirwa chakanyatsogadzirwa nemazvo, uye une mitemo yakasimba yekupenya, kuomarara, hunhu hwemakanika, kuomarara, kushivirira kwakarurama nezvimwe zviratidzo zvechiratidziro, saka chave mutungamiri mumitsetse yesimbi isina ngura.

1. Pfungwa yetambo yesimbi isina ngura yakanyatsogadzirwa

Kazhinji tinoti strip yesimbi isina ngura inoputirwa nechando ine ngura chaiyo ye600-2100N/mm2 uye ukobvu hwe0.03-1.5mm sestrip yesimbi ine ngura yakasimba. Kugadzira kwenguva kwakakosha zvikuru.

Pfungwa, hunhu uye mwero wekugadzirwa kwe304 high-strength usahihi wesimbi isina tsvina

2. Hunhu hwe304 tambo yesimbi isina ngura yakanyatsogadzirwa

Sezvo chigadzirwa ichi chiri chebasa rehunyanzvi, kuburikidza nematanho acho uye zviyero zvekugadzira, tinogona kunzwisisa hunhu hwacho mune zvinotevera:

1) Upamhi huri pasi pe600mm;

2) Kushivirira ukobvu i ±0.001mm, uye kushivirira kwehupamhi i ±0.1mm.

3) Hunhu hwepamusoro pechigadzirwa hunogona kusangana nezvinodiwa pazviitiko zvakasiyana-siyana, zvakaita sepamusoro pe2B, pamusoro peBA uye kunyange pamusoro wakakosha.

4) Ine hunhu hwepamusoro hwemakanika, uye kushushikana kwakakodzera kwegoho uye simba zvinogona kugadzirwa zvichienderana nezvinodiwa nevatengi.

5) Hukuru hwetsanga hunenge hwakafanana. Kana chigadzirwa chanyatsobatidzwa, hukuru hwetsanga hunofanira kudzorwa pa7.0-9.0. Panguva imwe chete, mashandiro esimba akaenzanawo, uye kuchinja kwekuoma kwetsanga kunofanira kudzorwa pakati pe±5-10Hv.

6) Pamusoro pezvo, 304 simbi dzakasimba kwazvo dzine zvinodiwa zvakanyanya kuti dzive dzakatwasuka uye dzakanaka.

3. Mitemo yekugadzira zvidimbu zvesimbi

1) ASTM A666: Iyi chiyero inovhara zvinhu zvesimbi isina ngura zvinogadzirwa nesimbi, kusanganisira rudzi rwe304, uye inotsanangura zvinodiwa pakuumbwa kwemakemikari, hunhu hwemakanika, saizi, uye kushivirira.

2) EN 10088: Iyi chiyero cheEurope chinopa mamiriro ehunyanzvi ekutumira simbi isina ngura, kusanganisira giredhi 1.4301, rinoenderana neAISI 304. Rinofukidza saizi, kushivirira, mamiriro epamusoro, uye hunhu hwemakanika.

3) JIS G4305: Iyi standard yekuJapan inotsanangura magadzirirwo esimbi isina ngura inotonhorera, kusanganisira mhando yeSUS304, yakaenzana neAISI 304. Inosanganisira kuumbwa kwemakemikari, hunhu hwemakanika, saizi, uye kushivirira.

Ehe, mugadziri wega wega anewo mitemo yake yekugadzira. Makambani mazhinji ekugadzira anogadza mitemo yawo yekugadzira zvichibva pamitemo yesimbi inotonhorera kana zvichienderana nezvinodiwa nevatengi. Zvisinei, vagadziri vazhinji vanowanzoona kuti chigadzirwa chine zvinodiwa zvakanyanya pakusiyana, izvo zvinogona kusangana nezvinodiwa nevatengi vakasiyana-siyana.
