Fasahar shirye-shirye da aikace-aikacen babban maƙasudin tungsten mai tsabta

Saboda high zafin jiki kwanciyar hankali, high electron ƙaura juriya da high electron watsi coefficient na refractory tungsten da tungsten gami, high-tsarki tungsten da tungsten gami hari ana amfani da yafi amfani ga masana'anta kofa lantarki, dangane wiring, yada shingen yadudduka, da dai sauransu na semiconductor. hadedde da'irori, kuma suna da manyan buƙatu don tsabta, ƙazanta abun ciki, yawa, girman hatsi da tsarin hatsi iri ɗaya na kayan.Yanzu bari mu dubi abubuwan da suka shafi shirye-shiryen tungsten mai tsabta mai tsabta.

　　1. Effect na sintering zafin jiki

Tsarin halittar tungsten da aka yi niyya gabaɗaya ana yin shi ta hanyar latsawa mai sanyi.Tungsten hatsi za su yi girma a lokacin aikin sintering.Girman ƙwayar tungsten zai cika rata tsakanin iyakokin hatsi, don haka inganta yawan maƙasudin tungsten.Tare da haɓakar lokutan sintering, haɓakar ƙimar tungsten yana raguwa sannu a hankali.Babban dalilin shi ne cewa bayan da yawa sintering, ingancin tungsten manufa bai canza da yawa.Saboda yawancin ɓangarorin da ke cikin iyakar hatsi suna cike da lu'ulu'u na tungsten, bayan kowane ɓangarorin, ƙimar canjin girman girman tungsten ya kasance ƙanƙanta sosai, yana haifar da iyakataccen sarari don ƙimar tungsten ya karu.Tare da tsarin sintering, hatsin tungsten da suka girma suna cika cikin ɓatacce, wanda ke haifar da mafi girman girman maƙasudi tare da ƙarami girman barbashi.

　　2.Tasirin rike lokaci

A daidai wannan yanayin zafin jiki, za a inganta ƙaƙƙarfan maƙasudin tungsten tare da tsawaita lokacin riƙewar sintering.Tare da tsawaita lokacin riƙewa, girman ƙwayar tungsten zai ƙaru, kuma tare da tsawaita lokacin riƙewa, lokutan girma na girman hatsin zai ragu sannu a hankali, wanda ke nufin cewa haɓaka lokacin riƙewa kuma zai iya haɓaka aikin aikin. tungsten manufa.

　　3. Tasirin mirgina akan kaddarorin da aka yi niyya

Don haɓaka yawan abubuwan tungsten da aka yi niyya da samun tsarin sarrafa kayan tungsten, matsakaicin zafin jiki na mirgina kayan tungsten dole ne a aiwatar da shi ƙasa da zazzabi na recrystallization.Idan yanayin jujjuyawar billet ɗin manufa ya yi girma, tsarin fiber ɗin billet ɗin da aka yi niyya zai zama mara nauyi, kuma akasin haka.Lokacin da dumin mirgina ya kai fiye da 95%.Ko da yake za a kawar da bambancin tsarin fiber da ke haifar da nau'in hatsi na asali daban-daban ko yanayin zafi daban-daban, tsarin ciki na abin da ake nufi zai samar da tsarin fiber iri ɗaya, don haka mafi girman yawan aiki na mirgina mai dumi, mafi kyawun aikin da aka yi niyya.
