Yakakosha budiriro maitiro e Vacuum mhepo choto

Mumaitiro ekusimudzira yeashoma asiri oxidizing kupisa kupisa tekinoroji, kuvandudzwa kwevacuum atmosphere furnace inokurumidza. Mune yazvino madiki akasiyana uye kugadzirwa kwakawanda, kunyanya kudzima kupenya, kuvharisa, kudzima moto, carbonitriding quenching, uye gasi nitrocarburizing yekabhoni simbi uye general alloy structural simbi zvikamu zvichiri kunyanya kuenderana nekushandiswa kweanodzoreka mamiriro ekunze. Naizvozvo, mumhepo choto kupisa kurapwa ichiri chikamu chikuru chepamusoro kupisa tekinoroji.

Iyo gasi sosi yemamiriro ekugadzirira. Mukuita kugona nekusimudzira mamiriro ekunze anodzoreka, nyika yedu yasvika kure mukugadzirisa dambudziko remhepo. Majenareta ekutanga endothermic ainyanya kushandisa liquefied gasi, kureva, propane kana butane nekuchena kwepamusoro. Mumakore achangopfuura, zvakasimbiswa kuti nyika yangu yakawanda gasi zviwanikwa zvakagadzira mamiriro akanaka ekugadzirira endothermic atmospheres ne methane. Kushandiswa kwemhepo yechizvarwa chakananga pasina choto chakasviba zvakare inzira isingagoni kuregererwa.

Vacuum atmosphere choto chekudziisa midziyo. Iyo yakavharwa yakawanda-chinangwa chevira uye yakawanda-chinangwa chekugadzira tambo ine yakakwirira dhigirii ye otomatiki, yakakura kugadzirwa kuchinjika uye kushanda kwakasimba, saka ivo vanoshandiswa zvakanyanya.

Iko kukanganiswa kudiki kweiyo workpiece yakakosha zvakanyanya mukana wevacuum atmosphere vira. Maererano neruzivo rwemumba nekune dzimwe nyika, kukanganiswa kwechoto chemuchadenga chinongova chikamu chimwe muzvitatu cheiyo yekudziya nekudzima munyu. Zvinokosha zvikuru kudzidza nzira dzekudziya dzevacuum yezvinhu zvakasiyana-siyana uye zvikamu zvine mazinga akasiyana-siyana uye mitemo yekukanganisa pasi pemamiriro akasiyana-siyana ekutonhora, uye kuitevedzera nekombuta, iyo yakakosha zvikuru mukusimudzirwa kwevacuum atmosphere furnace tekinoroji. . Kufanana kwekuyerera kwemhepo panguva yekudziya kwevacuum, yakajairwa kudzvanywa kana yakanyanya kudzvanywa mweya ine simba guru pakudzima uye kupararira kwemhando yezvikamu. Kushandiswa kwekombiyuta yekuenzanisa nzira yekudzidza mutemo wekutenderera kwemhepo muchoto kune zvakakosha zvikuru pakuvandudza kuchinja kwemaitiro echoto. Vacuum carburizing inzira inogoneka yekuwana yakakwira tembiricha carburizing.

Nekudaro, kupisa kwenguva yakareba pakupisa kwakanyanya kuchaita kuti austenite saizi yezviyo zvesimbi zhinji ikure zvakanyanya. Kune chaiyo simbi yepamusoro-yekupisa carburization, pesvedzero yekudzokorora uye kudzima pazvinhu zvemidziyo uye workpieces ichadzidzwa, uye optimization yevacuum infiltration ichadzidzwa. Carbon, kutonhora, kudziyisa uye kudzima maitiro uye michina inodiwa. Mumakore achangopfuura, kwave netsvakiridzo yepasirese uye kuvandudzwa kwemoto unopisa-mhando yekuvharisa vachishandisa mafuta egasi. Zvakanyanya kuoma kushandisa mafuta egasi kupisa muvacuum atmosphere vira. Kunyangwe paine chirevo chekuchengetedza simba, haisati iri iyo yakakosha nzira yebudiriro.
