Maitiro ekugadzira uye maitiro ekupisa-yakatenderedza ribbed simbi bara

Background maitiro:

MuRobar Rebar musika, HRB400E account yezve zvimwe. Iyo microalloy inosimbisa nzira ndiyo nzira huru yekugadzira HRB400E iri munyika. Iyo microotalloy inonyanya kuvanamuumi vhiya Nekuda kwekushaikwa kwemamineral zviwanikwa zvine unadium uye niobium, iyo yekugovera izvi zvinhu zvekupa zvakasimba. Naizvozvo, kana iyo alloy yezvinyorwa zveHRb400400E STEL Bar inogona kuderedzwa, ichabereka hombe hupfumi uye hwemagariro.

Mune tekinoroji iripo

Chinese patent cn104357741a inoburitsa mhando yeHRB400400400400400400400400400400400 Kuburikidza nenzira, chigadzirwa chakapera chinogadzirwa nekuderedza chigayo, chinogona kuve nechokwadi chekuti kupedzisa simbi yakatsvairwa yekudziya kwe730 ~ Chinese Patent CN11018451414A inoburitsa nzira yekugadzirira yeWire Wire φ6mm ~ hrb400400400e coilrew screw. Nerubatsiro rwevakasimba kupisa kugona kwemidziyo, kupisa kwakadzika kunotanga kubva mukudziya kwekudziya, uye kugadzirwa pasina microlloying kunoonekwa. Iko kukanganisa kwenzira iyi ndeyekuti izvo zvinodiwa neSimba uye kuita zvemotokari zvekutenderera kwemidziyo, uye kusimba kweiyo midziyo yekugadzira. Isina kukwana huwandu, zvakaoma kuvimbisa chiyero chekuita kwekuita.

Technical inonyora zvinhu:

Chigadzirwa chazvino chinovavarira kupa nzira yekugadzira nzira inopisa-yakadzika mbichana mbichana, kunyanya nzira yekupisa

Tekinoroji chirongwa chekugadzirwa kwazvino:

Iyo nzira yekugadzira yekupisa-yakakwenenzverwa rabbed simbi bar, iyo yekutsvaira yerwiyo Wire THE IS ire8 Iyo yemakemikari enziyo huwandu hwesimbi ndeye c = 0.20% ~ 0.25%, mn = 1.040,08%, v =. Matanho akakosha ekugadzirisa anosanganisira: tembiricha yemavara ndeye 1070 ~ 1130 ℃, iyo yekudzikisira kupisa ndeye 970 ℃, uye kupedzisa tembiricha inosvika 840 ~ 1000 ℃. 880 ℃; kuseta tembiricha 845 ~ 875 ℃; Yekupedzisira kupisa kupisa iri pazasi pekudzokorora kupisa tembiricha yeAustenite Zone; Kukurumidza Kutonhorera naFan pane Air-Colded Roller Tafura, Mhepo Vhoriyamu ndeye 100%; Tembiricha yeVhavha ndeye 640 ~ 660 ℃, tembiricha yeiyo his yekuchengetedza yekuchengetedza ndeye 600 ~ 620 ℃, uye iyo nguva iri mukushisa yekuchengetedza chifukidziro ndeye 45 ~ 55s.

Iyo nheyo yezvakagadzirwa: Mune tembiricha ye840-880 ℃, maAustenite eAusten anokandwa nekudzikisira deformation, asi recorsellization haina kuitika. Nekudaro, mabhendi ekusvibisa anogadzirwa muAustenite zviyo, uye magumo ezvikwata zvekushanduka kazhinji pamiganhu yezviyo, uye kune zvakare mabhendi ane miganho yekuparadza zviyo zvekupatsanurana. Munguva yekushandurwa kubva kuAustenite kuenda kuFernite, vese vaAustenite miganhu yezviyo uye nzvimbo inooneka yezviyo gadziriso yekuita seyisingachinjika nzvimbo yekupererwa. Tembiricha yakaderera ichipenya muyenyenzi inobvisa mutoro wekutenderera wekunyura uye wepakati kutenderera mill uye pre-kupedzisa mamirimita uye inowedzera hupenyu hwebasa remidziyo.

Mhedzisiro inobatsira yekugadzirwa iri seinotevera: Nekuwedzera huwandu husina kukwana kweVicroyloy, v uye C fomu dzinotakura, izvo zvakarongedzwa panguva yekutonhorera mushure mekununura, uye tamba basa rekusimbisa. Iyo inopisa-inopisa yeaya yechigadzirwa ine Simba reSimba re600-700mpa, Simba rezvikwereti zve420-500mpa, uye Agt> 10%, inovimbisa mari yakakwana. Simba rakabiwa rakasimba, uye huwandu hwekuita hwakakodzera hwuri pamusoro 99%. Iko kugadzirwa kwehunyanzvi kunogadzirisa dambudziko rekuti twist rolling

Nzira Dzakadzama

Zviri mukati meiyo chigadzirwa chazvino chinowanikwa chakarondedzerwa pazasi mune conjunction ine embodilimes.

Iyo nzira yekugadzira yeboka reWire Wire Wire wire ~8mm ~ φ10mrb400e yakabikwa sanesi. Maitiro ekunyepedzera ndewekuti: Kunobuda kupisa: 1080 ~ 1120 ℃, Kupedza Kupedza Tembiricha 640 ~, f, 65 ℃, nguva 620 ← 45 ~ 55s, uye inotonhorera sezvazviri. Kuumbwa kwemakemikari weWire yeWire yeiyo chigadzirwa chekugadzira chinoratidzwa muTafura 1, uye zvigadzirwa zveWire ter
