Valani mbale yolimba yolimba, yomwe ndi yovala bwino kwambiri, ndi chinthu cha mbale yapadera yomwe imagwiritsidwa ntchito mwapadera kuvala malo ogwirira ntchito. Imapangidwa ndi mbale yotsika yotsika komanso ya Alloy kuvala kosagwirizana.
Pulogalamu yachitsulo yofooka imakhala ndi mawonekedwe amphamvu kwambiri komanso ovala kwambiri. The alloy wovala wosakanikirana-wosagonjetsedwa nthawi zambiri amakhala 1/3 mpaka 1/2 ya makulidwe athunthu. Mukamagwira ntchito, matrix amapereka katundu wokwanira monga mphamvu, kulimba ndi pulasitiki kuti mupewe zinthu zakunja, ndipo ma alloy ovala omwe amalephera kubzala amalephera kuthana ndi zomwe mwakhala nazo.
Pali mitundu ingapo ya mbale zowonongeka, kuphatikizapo makonda osokoneza bongo osokoneza bongo ndipo altoy amazimiririka. Mwachitsanzo, Kh60 Valiel Steel Steel ndi mtundu wa chinthu chomwe chimapangidwa ndi kuvala kwa alloy chofooka kwambiri komanso kuvala kosakanikirana ndi chitsulo chochepa ndi chipilala kudzera pa njira yowerengera. Magawo aluso a K Kin60 ovala zitsulo ndi motere: kuuma kwa nyimbo ndi 1700hv; Zinthuzo ndizotsika-zotsika-zamiyala yotsika, ndipo mitundu ina ya zowonjezera zovuta ndi Niobium Carbide ikhoza kuperekedwa molingana ndi zofunikira. Chromium ndi Boron alloy carbides ndi olemera; Kuumitsa kwa mawonekedwe osokoneza bongo omwe ali ndi vuto ndi C62-65 hrc; makulidwe ndi mamilimita 3 - 15; Zovuta zolimba ndizoposa 50%; Kutentha kwakukulu ndi 1000 ° C.
Kuphatikiza apo, mbale yolimbana ndi chitsulo 360 imakhalanso mtundu wa mbale zapamwamba kwambiri komanso zowoneka bwino kwambiri. Amapangidwa ndi ukadaulo wotsogola ndipo amakhala ndi mphamvu zambiri komanso mphamvu zochulukitsa, komanso kuvala bwino kukana ndi kukana.
2. Kugwiritsa ntchito mapepala osokoneza
2.1 mitundu yonse ya mafakitale
Mapulasitiki ocheperapo amapeza ntchito zambiri m'mafakitale osiyanasiyana. M'malo opanga zitsulo, amagwiritsidwa ntchito m'manda monga cresher ndi malamba onyamula, omwe nthawi zonse amachitidwa ndi abrasion komanso kukhudzidwa. M'mabizinesi amalashi, amagwira ntchito mosera za malasha ndi magawo a mining kuti athe kuthana ndi zovuta. Makampani ogulitsa simenti amagwiritsa ntchito mbale zowonongeka zowonongeka m'masiku ndi mphero zokuza kuti zitsimikizire moyo wautumiki wautumiki. M'magulu opanga magetsi, amagwiritsidwa ntchito m'mawonekedwe a malasha ndi makina ogwirira ntchito.
Mwachitsanzo, mbale yolimbana ndi chitsulo 360 imagwiritsidwa ntchito kwambiri m'minda monga magalimoto, njanji, kuyendetsa mafuta, makina, magetsi, ndi zomanga. Ndi yabwino kwambiri pazomwe zimapangitsa kuti makina azikhala ndi makina ogulitsa chifukwa cha kukana kwabwino kwambiri, kukana kwamphamvu, komanso kukana kutukuka.
2.2 mphamvu yayikulu
Poyerekeza ndi zinthu zina, mbale zosemphana ndi zitsulo zowonongeka zimapereka ndalama zambiri. Ngakhale mtengo woyambirira wa mbale zosagonjetsedwa kungakhale wokwera kwambiri kuposa zinthu zina zachikhalidwe, kuvala kwawo kwakukulu kukana ndi kulimba kumapangitsa ndalama zambiri pakapita nthawi. Mwachitsanzo, kampani yogwiritsa ntchito mbale zotsekemera popanga zomwe zimapangidwa zimachitika nthawi yopuma ya mankhwala ndikusinthidwa, zomwe zimapangitsa kuchuluka kwa zokolola ndi ndalama zolipirira.
Malinga ndi deta, ntchito yautumiki wambiri yofooka nthawi zambiri imakhalapo kangapo kuposa malo achitsulo wamba. Izi zikutanthauza kuti makampani amatha kuchepetsa ndalama zawo ndi zowononga pakapita nthawi. Kuphatikiza apo, magwiridwe antchito abwino kwambiri ovala zitsulo amachepetsa chiopsezo cha kulephera ndi kuchepa kwa zida zoletsedwa komanso kuchedwa kwambiri. Zotsatira zake, mafakitale ambiri ndi opanga amawonetsa zokonda zowonongeka zowonongeka.
3. Gulu lazinthu zakuthupi zowonongeka
3.1 mitundu wamba
Mafuta osokoneza bongo omwe amapezeka kawirikawiri ndi zigawo za Alsoy zosokoneza-zosagwirizana ndi chitsulo chochepa cha misika kapena chitsulo chotsika. Palinso kuponyedwanso mbale zosagonjetsedwa ndi zitsulo zozimiririka. Mwachitsanzo, mbale yolumikizira yolumikizira imapangidwa ndi kuphatikizira kwa alloy kuvala kosasamala ndi kuvuta kwambiri komanso kuvala bwino kwambiri pazitsulo.
3.2 mitundu yosiyanasiyana yamikhalidwe
Pali mitundu itatu ya mbale zowonongeka: mtundu wa General-code, kapena mtundu wambiri, komanso mtundu wa kutentha kwambiri.
Cholinga chachikulu chomwe chimakhala ndi vuto lililonse ndikukhazikika ndipo ndi yoyenera kuvala. Ili ndi kuvala bwino kukana ndi mphamvu yolimba. Magawo aluso amathanso kuphatikiza mtundu wina wambiri, nthawi zambiri pafupifupi 50-60 hrc. Malingaliro a zinthuzi nthawi zambiri amakhala ndi zinthu monga chromium ndi manganese kuti azitha kuthana. Pochita magwiridwe, zitha kupirira digiri ina ya abrasion ndipo imagwiritsidwa ntchito kwambiri m'makampani monga makina amakina.
Pulogalamu yolimbana ndi zovuta zomwe zimapangidwa zimapangidwa kuti zithetse zovuta zolimba. Imakhala ndi nthawi yayitali komanso yolimbana kwambiri. Zinthuzo nthawi zambiri zimakhala ndi zinthu za Aloya zomwe zimathandizira kukana. Mwachitsanzo, mitengo ina yopanda tanthauzo imatha kukhala ndi kuuma kozungulira 45-55 hrc koma kuthana ndi mphamvu kwambiri. Mtunduwu ndi woyenera kugwiritsa ntchito komwe zida zimakhudzidwa ndi zovuta zomwe zimakhudzidwa, monga mu migodi ndi mafakitale omanga.
Kutentha kwambiri kwa madzi osagwirizana ndi kutentha kumatha kupirira kutentha kwambiri. Amapangidwa ndi zinthu zapadera za Aloya zomwe zimatha kukhalabe zokhazikika pamatenthedwe kwambiri. Magawo aluso amatha kuphatikiza kutentha kokwanira mpaka 800-1200 ° C. Malingaliro azinthuzi nthawi zambiri amakhala ndi zinthu monga Nickel ndi Cromium kuti atsimikizire kutentha kwambiri. Pochita ntchito, imagwiritsidwa ntchito kwambiri malo ambiri ngati mikangano ndi mafayilo mu mafakitale a simenti.
