Kusiyana kwa kusankha kwa zida zopukutira ozizira komanso mizere yozungulira yotentha

M'makampani ogubuduza zitsulo, mipukutu yomwe imagwiritsidwa ntchito popiringitsa ozizira komanso mizere yotentha ndi yofunika kwambiri.Chifukwa cha njira zosiyanasiyana komanso malo ogwiritsira ntchito awiriwa, palinso kusiyana kwakukulu pakusankhidwa kwa zinthu za mipukutu.Tidzafufuza mwatsatanetsatane kusiyana kwa kusankha kwa zinthu pakati pa mipukutu yomwe imagwiritsidwa ntchito pozizira ndi mizere yotentha.

Choyamba, pali kusiyana kwakukulu kwa kutentha kwa ntchito pakati pa mizere yozizira yozungulira ndi mizere yotentha yozungulira.Mizere yopukutira yotentha imachitika pakatentha kwambiri ndipo nthawi zambiri imafunika kupirira kutentha mpaka 1200 ℃.Chifukwa chake, zida zopukutira pamzere wowotcha ziyenera kukhala ndi magwiridwe antchito apamwamba kwambiri komanso kukana kutopa kwamafuta.Zida zodziwika bwino zimaphatikizapo chitsulo chokwera cha chromium, chitsulo chothamanga kwambiri, ndi chitsulo chosagwira kutentha.Zidazi sizimangosunga mphamvu ndi kuuma pa kutentha kwakukulu, komanso zimatsutsa makutidwe ndi okosijeni ndi dzimbiri zotentha, potero zimakulitsa moyo wautumiki wa masikono.

M'malo mwake, mizere yozizira yozungulira imachitika kutentha kapena pafupi ndi chipinda, kotero mipukutuyo siyenera kupirira kutentha kwambiri.Komabe, panthawi ya kuzizira kozizira, chifukwa cha zofunikira zapamwamba za pamwamba pa pepala lachitsulo, kuuma kwa pamwamba ndi kuvala kukana kwa mipukutu ndizofunikira kwambiri.Mizere yozungulira yozizira nthawi zambiri imapangidwa ndi zinthu monga chitsulo cha aloyi, chitsulo cha carbon, kapena chitsulo cha chrome.Zidazi zimakhala ndi kuuma kwakukulu komanso kukana kuvala, zomwe zingathe kuonetsetsa kuti pamwamba pa mipukutuyo siivala mosavuta panthawi yogwiritsidwa ntchito mwamphamvu kwambiri, potero kuonetsetsa kuti pamwamba pa mankhwalawa.

Kachiwiri, katundu ndi kukanikiza kwa mipukutu pa ozizira kugudubuza ndi otentha mizere yogudubuza ndi osiyana.Mzere wowotchera wotentha umayenera kukakamiza zitsulo zazitsulo zotentha kwambiri kuti zikhale zosiyana siyana za mbale zachitsulo, ndipo mipukutuyo iyenera kupirira kupanikizika kwakukulu ndi kukhudzidwa, kotero kuti zinthuzo zimafunika kuti zikhale ndi mphamvu zambiri komanso zolimba zabwino.Mzere wozizira wozungulira, chifukwa chochitidwa ndi kutentha kocheperako, makamaka umanyamula kukameta ubweya wambiri komanso kukangana pamipukutu.Chifukwa chake, kusankha kwazinthu zoziziritsa kuzizira kumayang'ana kwambiri kukana kwawo kuvala komanso kukana kutopa.

Kuphatikiza apo, kupanga mizere yoziziritsa kuzizira nthawi zambiri kumaphatikizapo njira zambiri zochizira pamwamba, monga chrome plating, quenching, etc., kuti apititse patsogolo kulimba kwawo komanso kukana kuvala.Komabe, chifukwa chogwira ntchito m'malo otentha kwambiri, njira zochizira pamwambazi sizoyenera mizere yozungulira yotentha.M'malo mwake, ntchito yawo imakulitsidwa kudzera mu kaphatikizidwe ka aloyi ndi kutentha kwa zinthu zomwezo.

In summary, there are significant differences in the material selection of rolls for cold rolling and hot rolling lines, mainly reflected in the different requirements for working temperature, load, pressure, and surface quality. Hot rolling line roll materials need to have excellent high-temperature performance and thermal fatigue resistance, while cold rolling line roll materials emphasize high hardness and high wear resistance. Understanding and correctly selecting suitable roll materials is of great significance for ensuring the stability of the rolling process and product quality.
