Cold steel iphuma: nezinhlamvu, izici, isicelo

steel Cold iphuma (s / a) - omunye ezichumayo yesimanje metal-roll. Inombolo ephelele ekhiqizwa steel shidi ngokuqhubekayo okwandisa ivolumu. It ikhiqizwa njengoba leli gama lisikisela, indlela ugingqe abandayo. metal Ductile isingathwa ngumuntu ingcindezi ekhethekile ngaphandle preheating. Itholakala izinhlobo ezimbili - uyibhala abandayo iphuma kanye imiqulu. imikhiqizo Iphele kungaba ngobude nosayizi, ngosiko Imi nge kokucindezelwa.

Izimpawu steel abandayo iphuma

Nesidingo esikhulayo steel abandayo iphuma ngenxa ephakeme izici izinga ngaphandle hot umkhiqizo iphuma. Ngaphezu kwalokho, ishidi ukujiya metal 1 mm ngaphansi kwezomnotho nokwenzeka inqubo aqandayo. rolling Cold is phansi carbon ezivamile, eliphezulu carbon, lezinsimbi elixutshiwe futhi ephezulu ingxubevange, ukugqwala nemithi, ukushisa ukumelana nokushisa ukumelana Alloys. Ukwakheka kwamakhemikhali steel iphathwa inquma izakhiwo steel nganxanye nobukhulu bayo. Ngakho, i-athikili eziyinkimbinkimbi olubunjiwe esetshenziswa ongaphakeme-carbon steel amashidi, abandayo iphuma, GOST 19904-90. the microstructure metal emva kweqa kakhulu inquma plasticity yayo, ceteris paribus.

Cold steel iphuma ikhiqizwa 0.25-5.0 mm obukhulu futhi itholakala amashidi ezinobukhulu obuhlukahlukene - kusukela 510h710 mm kuya 1250h2500 mm. Steel 0.25-2 mm obukhulu lashukumisa kungenziwa enikeziwe. Cold iphuma steel ishidi transformer ukukhiqiza 0,28-0,5 mm ubukhulu ishidi obukhulu 750-1000 mm. Ngu transformer steel izimfuno ebalulekile ukubeka phambili, okungukuthi - ukubaluleka kazibuthe ecucuza ukuminyana futhi watt ukulahlekelwa isixazululo. Futhi ukukhiqiza ishidi iphuma steel roll lezinsimbi kwesakhiwo abandayo, ingxubevange eliphezulu lezinsimbi kwesakhiwo injongo ekhethekile kagesi ongaphakeme carbon ne-silicon lezinsimbi. Ikhishwa abandayo iphuma strip entwasahlobo, ithuluzi, banakekele izifunda kazibuthe.

Izici ishidi abandayo iphuma

jikelele-njongo ishidi abandayo iphuma ikhiqizwa lezinsimbi Ukwakheka kabani chemical ichaza GOST 1050-88: 08ps, 08kp, 10PP, 10ps, 15 ps, 15kp, 20ps, 20kp, 25, 30, 35, 40, 45. Ukuze uthole ugingqe abandayo is phansi izinga isibhakela amamaki steel 08U, 08kp futhi 08ps. Cold iphuma steel ebusweni bushelelezi futhi eqonde kakhulu ngamajamo weJiyomethri.

Ngokuphambene negama layo, steel abandayo iphuma ngeke kungayitholi ekwelapheni ukushisa. Noma yimuphi metal abandayo iphuma ikhiqizwa billet ashisayo iphuma.

ukukhiqizwa steel iphuma abandayo

Ishidi abandayo iphuma kwenziwa ngezindlela ezimbili: ishidi elilodwa noma roll. Lapho ishidi-indlela kukhicite steel ashisayo iphuma emva kweqa abandayo iyasikwa ibe amashidi, okuye eceleni wathumela kucutshungulwe (annealing, eqondisa et al.).

Ngo inqubo zesimanje zokukhiqiza i umqulu ntandokazi. Kulokhu, zonke izigaba yokukhiqiza of x / k steel imiqulu kanye wenziwa imikhiqizo ngomumo eyenziwe nge cut ibhukwana noma othomathikhi ku amashidi. indlela Round kwenza ezenzakalelayo ngobuningi processing imisebenzi, kwandisa isivuno umkhiqizo osuphelile, ngcono izakhiwo insimbi ifomu ukuzinza ngenxa senqubo yokukhiqiza. Nale ndlela okwandisa ekhishwa imikhiqizo siphelile kungenzeka ezindaweni ezifanayo. Kwezinye izimo steel abandayo iphuma ihlinzekwa e imiqulu. Kuye senqubo yokukhiqiza of ezinye amabhizinisi umshini wokwakha, kuyasiza inciphise udoti. Esikhathini ukukhiqizwa steel abandayo iphuma imisebenzi okuphoqelekile okwenziwa ezikhungweni uhlanza descaled strip ashisayo iphuma, edonsa Izigayo ukuba (esethola noma eqhubekayo), ukwelashwa ukushisa, ukuzisika, eqondisa.

Ukuhlukanisa izici hot iphuma amakhaza iphuma

metal Zezıhlabane kulula ukucubungula. Izihloko eyenziwe ugingqe esishisayo isetshenziswa kabanzi ongaphakeme-ebangeni, ephansi izindleko steel. imikhiqizo Iphele ivame ukwembozwa esikalini futhi zidinga ukwelashwa okwengeziwe. Njengoba kungenakwenzeka ukubala imikhawulo ukusonteka metal ngesikhathi lwaluyophola ashisayo geometry metal iphuma kuyinto kobukhulu ezahlukene (ukujiya engalingani, okungajwayelekile emaphethelweni namakhona).

indlela Cold-rolling kwenza kube nokwenzeka ukuba silondoloze ngqo edingekayo Ubukhulu imikhiqizo. Ebusweni iphuma bushelelezi, ukujiya iyunifomu ezinjalo, ngakho ukuphathwa umkhiqizo wokugcina lincishisiwe, futhi ngezinye izikhathi ngisho edingekayo. Ngenxa isakhiwo eyohlobo, metal abandayo iphuma okuhlala isikhathi eside futhi sinezici kangcono ikhefu, eguqa, elula. Ukuze izinsimbi okusezingeni eliphezulu amamaki steel.

Isicelo steel abandayo iphuma

metal Cold iphuma isetshenziswa emikhakheni eminingi: ku bodywork yezimoto, imishini izakhiwo, imishini ezimbonini, izingxenye zemishini, ukwakhiwa, imboni lehlanganisa tinhlelo, ukukhiqizwa zasendlini.

Kushone 3 steel ezibandayo - omunye izindleko eqolo. Ubuncane-mpilo okuqukethwe sithuthukisa homogeneity isakhiwo, plasticity futhi ukugqwala ukumelana. Isetshenziselwa kanzima metal izakhiwo kanye izakhi umthwalo eziveza, bobunjwa kwesakhiwo, izingcezu ipayipi nokufakwa. steel Cold iphuma isetshenziswa womshini izingxenye wadalula kuhlasela ezishisayo futhi amakhemikhali.
