Kumusoro Kupisa kurapwa kwakakamurwa kuita zvikamu zviviri: imwe ndeyekupaza kwemvura uye kupisa kupisa kurapwa, uye imwe iri kurapwa kwemakemikari. Iyo nzira yekuyedza yekuyedza iri seinotevera:
1. Svutugadzike Rinopedza uye kupisa kupisa kupisa
Specurned Quenching uye kutsamwa kupisa kurapwa kunowanzoitwa nekunyanyisa kupisa kana murazvo unopisa. Iyo huru technical parameter ndeyekuomarara, kuomarara kwenzvimbo uye kusanzwisisika kwakaomeswa. Vickers kuomesa tester Kuedza kwekuedza kusarudzwa kunoenderana nekudzika kweiyo inoshanda yakaomeswa denderedzwa uye kuomarara kweiyo yekushanda. Pane michina mitatu yakaoma inobatanidzwa pano.
. Inogona kushandisa simba rekuyedza ye 0.5-100kg yekuyedza iyo nzvimbo inoomesesa yakaonda se0.05mm gobvu. Kurongeka kwayo kwakakwira uye kunogona kusiyanisa anoshanda-kupisa works. Musiyano ushoma mukuomarara pamusoro penzvimbo, mukuwedzera kweiyo inoshanda yakaomeswa denderedzwa yakawonekwa tester, saka inokodzera kushatisa tester yekukanganisa kurapa kwekurapa kana kushandisa nhamba yakakura yekurapa kurapwa kwekupedza.
. Pane zviyero zvitatu zvezvipenga zveLollwewell hardness tester kusarudza kubva. Inogona kuyedza akasiyana pasi pebasa rakaomeswa neyechinonyanya kushanda dura yakadzika inopfuura 0.1mm. Kunyangwe iko kurongeka kweiyo nzvimbo yeRopewell kuomarara kweTester haina kukwirira seyaVickers kuomesa tester, inogona kutosangana nezvinodiwa seyekucherekedza nzira yemhando yemhando uye kuongororwa kwekutarisa kwezvirimwa zvekupisa. .Mamwe zvakare ane hunhu hwekushanda kwakareruka, kushandisa kwakakodzera, mutengo wakaderera, kuraswa kwekutanga, uye kuverenga zvakananga kwekuomesa tsika. Iyo nzvimbo yeRoundwell Hardness Tester inogona kushandiswa kukurumidza uye isiri-yekuparadza yekuona mabhatani ekupfura kupisa-kwebasa rimwe nerimwe. Iyo yakakosha kwazvo kune simbi yekugadzirisa uye michina yekugadzira mafekitori. Kana iyo nzvimbo yekupfura yekupisa zvakanyanya kuomarara yakakora, iyo Dombowell Hardness Tester inogona zvakare kushandiswa. Kana iko kupisa kwekurapa kuomarara kwechiitiko chiri 0.4-0m, iyo hra chiyero inogona kushandiswa. Kana iyo yakaomeswa layer yakadzika kana ichidarika 0.8mm, iyo HRC chiyero inogona kushandiswa. Vickers, Rockwell uye Superficial Rockwell Matanho matatu akaomesesa anogona kutendeuka mukati, anotendeuka kuita zviyero, zvidhori kana tafura inoenderana. Iyo American Standard ASTM uye iyo Chinese yakajairwa GB / T yakapihwa.
(3. Kana kuyera, kutariswa kunofanirwa kubhadharwa kune iyo nzvimbo yekupedza uye ukuru hwese hwenzvimbo yebasa. Iyi yekuyera nzira haina vickers uye dombowelly testery yakaoma ndeyechokwadi, asi yakakodzera pane-saiti kuyerwa mufekitori.
2. Kemical kupisa kurapwa
Kurapa kwemakemikari ndiko kupinza pamusoro peiyo yekushanda neatomu dzechigadzirwa zveimwe kana zvinoverengeka zvemakemikari zvinhu, nekukasira kuchinjisa midziyo yemakemikari, kurongeka uye kuita kweiyo nzvimbo yebasa. Mushure mekudzokorora nekudzika tembiricha, pamusoro pebasa rekushanda kune zvakakwirira uye kupfeka kuramba. Uye bata simba ruregedza, uye musimboti webasa rekushanda une simba rakakura uye kuoma. Iyo huru technical paramita yemakemikari yekupisa kurapa kwebasa rekushanda ndeyekudzika kweiyo yakadzika yeiyo yakaoma layer uye kuomarara pamusoro penzvimbo. Iyo chinhambwe iyo iyo kuomarara kuomesa kusvika pa50hrc ndiyo inoshanda yakaomesesa yakadzika. Iyo nzvimbo yekumusoro bvunzo yekudziya kwemakemikari inobata mabasa akafanana neyakaomeswa bvunzo yemusoro yakadzurwa kupisa kwakadzora. Vickers kuomesa testers, pasi rockwell hardness testers kana matombo emickwell akawandisa anogona kushandiswa. Kuomesa tester kuti uone, chete ukobvu hwekutora niti
3. Kurapa kwemuno kupisa
Kana nzvimbo dzekupfura dzemuno dzinoda zvakakwirira zvakakwirira zveko, kupfupika kwemuno kupisa kunogona kuitisa nzvimbo yekupisa Kana iyo yekupisa kurapa yakaomeswa denderedzwa iri isina kudzika, nzvimbo yeRopewell Hardness Tester inogona kushandiswa kuyedza iyo HRN Hardness kukosha.
