1. Oyenera zinthu wosanjikiza makulidwe

Mphero yoyima imagwira ntchito pa mfundo ya kuphwanya bedi zakuthupi. Bedi lazinthu lokhazikika ndilofunika kuti chigayocho chizigwira ntchito mosalekeza komanso chokhazikika. Ngati zinthu zosanjikiza ndi wandiweyani kwambiri, mphamvu akupera adzakhala otsika; ngati zinthu wosanjikiza ndi woonda kwambiri, izo mosavuta kugwedera mphero. Kumayambiriro kwa kugwiritsidwa ntchito kwa manja odzigudubuza ndi kugaya chimbale akalowa, makulidwe a zinthu wosanjikiza amawongoleredwa pafupifupi 130mm, amene akhoza kupanga khola wosanjikiza zinthu ndi kulamulira katundu ofukula mphero makina chachikulu kusinthasintha mu osiyanasiyana wololera;

Pamene ntchito ofukula mphero wodzigudubuza manja ndi akalowa mbale wadutsa akuthamanga-mu nthawi, makulidwe a zinthu wosanjikiza ayenera moyenerera chinawonjezeka ndi za 10mm, kotero kuti wosanjikiza zinthu ndi khola, akhoza kukhala ndi zotsatira zabwino akupera, ndi kuonjezera linanena bungwe ola; Manja odzigudubuza ndi mbale zomangira zimavala pambuyo pake, makulidwe a zinthuzo ayenera kuyendetsedwa pa 150 ~ 160mm, chifukwa chosanjikiza chakuthupi chimagawika mosiyanasiyana pakatha kuvala, kugaya kumakhala koyipa, kukhazikika kwa zinthu zosanjikiza kumakhala koyipa, ndipo chodabwitsa cha kumenya pini yoyika makina chidzachitika. Chifukwa chake, kutalika kwa mphete yosungirako kuyenera kusinthidwa munthawi yake molingana ndi mavalidwe a malaya opindika a mphero ndi mbale yomangira kuti muchepetse makulidwe oyenera.

Pa ntchito chapakati ulamuliro, makulidwe a zinthu wosanjikiza tingayeruzidwe ndi kuona kusintha magawo monga kuthamanga kusiyana, khamu panopa, mphero kugwedera, akupera chotuluka kutentha, ndi slag kumaliseche ndowa panopa, ndi khola zinthu bedi akhoza lizilamuliridwa ndi kusintha kudyetsa, akupera kuthamanga, liwiro la mphepo, etc. kuchepetsa kupanikizika kogaya, ndipo kugaya chimbale zakuthupi amakhala coarser, ndipo potero zinthu slagging amakhala kwambiri, ndi wosanjikiza zinthu kumakhala wandiweyani; liwiro la mphepo mu mphero ukuwonjezeka, ndi zinthu wosanjikiza amakhala thicker. Kuzungulira kumapangitsa kuti zinthu zosanjikiza zikhale zokhuthala; kuchepetsa mphepo kumachepetsa kufalikira kwa mkati ndipo zinthu zosanjikiza zimakhala zowonda. Kuphatikiza apo, chinyezi chokwanira chazinthu zogaya chiyenera kuyendetsedwa pa 2% mpaka 5%. Zida ndizouma kwambiri komanso zabwino kwambiri kuti zikhale ndi madzi abwino ndipo zimakhala zovuta kupanga wosanjikiza wazinthu zokhazikika. Panthawi imeneyi, kutalika kwa mphete yosungirako kuyenera kuwonjezereka moyenerera, kupanikizika kwa kugaya kuyenera kuchepetsedwa, kapena kupanikizika kwakupera kuyenera kuchepetsedwa. Madzi amapopera mkati (2% ~ 3%) kuti achepetse madzi amadzimadzi ndikukhazikitsa zinthu zosanjikiza.

Ngati zinthuzo ndi zonyowa kwambiri, malo opangira batching, sikelo ya lamba, valavu yotsekera mpweya, ndi zina zotero, zidzakhala zopanda kanthu, zotsekedwa, zotsekedwa, ndi zina zotero, zomwe zidzakhudza kugwira ntchito mokhazikika kwa mphero, motero zimakhudza nthawi ya siteshoni. Kuphatikiza zinthu zomwe tazitchula pamwambapa, kuwongolera zinthu zosanjikiza zokhazikika komanso zomveka, kusunga kutentha pang'ono kwa mphero ndi kusiyana kwamphamvu, ndikuwonjezera kufalikira kwazinthu zabwino ndi njira zabwino zogwirira ntchito kuti muwonjezere kupanga ndikupulumutsa mphamvu. Kutentha kotuluka kwa mphero yoyamba nthawi zambiri kumayendetsedwa pa 95-100 ℃, yomwe imakhala yokhazikika, ndipo kusiyana kwapakati kumakhala kozungulira 6000-6200Pa, komwe kumakhala kokhazikika komanso kopindulitsa kwambiri; kutentha kotulukira kwa mphero yachiwiri nthawi zambiri kumayendetsedwa mozungulira 78-86 ℃, yomwe imakhala yokhazikika, ndipo kusiyana kwapakati kumakhala pakati pa 6800-7200Pa. Wokhazikika komanso wopindulitsa.

2. Kuwongolera liwiro la mphepo

Mphero yoyimirira ndi mphero yowombedwa ndi mphepo, yomwe makamaka imadalira mpweya wozungulira ndi kunyamula zipangizo, ndipo kuchuluka kwa mpweya wabwino kuyenera kukhala koyenera. Ngati kuchuluka kwa mpweya sikukwanira, zopangira zoyenerera sizingatulutsidwe munthawi yake, zosanjikiza zakuthupi zidzakhuthala, kuchuluka kwa kutulutsa kwa slag kumawonjezeka, kuchuluka kwa zida kudzakhala kwakukulu, ndipo zotulutsa zidzachepa; ngati mpweya wa mpweya uli waukulu kwambiri, zosanjikiza zakuthupi zidzakhala zoonda kwambiri, zomwe zidzakhudza kugwira ntchito kokhazikika kwa mphero ndikuwonjezera mphamvu yogwiritsira ntchito fan. , chifukwa chake, voliyumu ya mpweya wa mphero iyenera kufanana ndi zomwe zimachokera. Kuchuluka kwa mpweya wa mphero yoyima kungasinthidwe kudzera pa liwiro la fan, kutsegula kwa fan, etc. Kuti mumve mawu aposachedwa, chonde lemberani.
