Mbale Yachitsulo ya AR400

Kufotokozera Kwachidule:

Mbale yachitsulo yosagwira ntchito (AR) ndi mbale yachitsulo yokhala ndi mpweya wambiri wa kaboni. Izi zikutanthauza kuti AR ndi yolimba chifukwa cha kuwonjezera kwa kaboni, komanso yolimba komanso yolimba chifukwa cha kuwonjezera kwa ma alloys.

Mapulogalamu Opangira Mbale Zachitsulo Zosamva Kutupa

● Ma AR235 plates amapangidwira kuti azigwiritsidwa ntchito pang'ono pomwe amapereka mphamvu yolimba yolimbana ndi kuwonongeka poyerekeza ndi chitsulo cha kaboni.
● Ma AR400 ndi ma plate achitsulo apamwamba kwambiri omwe samva kusweka omwe amachiritsidwa ndi kutentha ndipo amalimba. Mphamvu zomangira ndi kukongoletsa bwino.
● AR450 ndi mbale yosamva kusweka yomwe imagwiritsidwa ntchito m'njira zosiyanasiyana pomwe mphamvu yochulukirapo pang'ono imafunika kuposa AR400.
● Ma AR500 plates ndi oyenera kugwiritsidwa ntchito m'migodi, m'nkhalango komanso m'nyumba.
● AR600 imagwiritsidwa ntchito m'malo omwe zinthu zimawonongeka kwambiri monga kuchotsa zinthu zonse, kukumba migodi, komanso kupanga mabaketi ndi zinthu zosweka.
Mbale yachitsulo yolimbana ndi kubala (AR) nthawi zambiri imapangidwa ngati yazunguliridwa. Mitundu/magiredi a zinthu za mbale yachitsulo izi zapangidwa makamaka kuti zigwiritsidwe ntchito nthawi yayitali m'malo ovuta. Zinthu za AR ndizoyenera kugwiritsidwa ntchito m'malo osiyanasiyana monga migodi/kukumba miyala, zonyamulira, kukonza ndi kumanga zinthu, komanso kusuntha nthaka. Opanga mapulani ndi ogwira ntchito m'mafakitale amasankha zitsulo za mbale ya AR akamayesetsa kuwonjezera nthawi yogwirira ntchito ya zinthu zofunika kwambiri, ndikuchepetsa kulemera kwa chipangizo chilichonse chomwe chagwiritsidwa ntchito. Ubwino wogwiritsa ntchito zitsulo za mbale zosagwirizana ndi kubala pogwiritsa ntchito zinthu zomwe zimakhudzana ndi kugwedezeka ndi/kapena kutsetsereka ndi zinthu zokwawa ndi waukulu kwambiri.

Mapepala achitsulo a alloy osagwira ntchito nthawi zambiri amakhala okana kutsetsereka ndi kugwedezeka. Mpweya wambiri wa kaboni mu alloy umawonjezera kuuma ndi kulimba kwa chitsulocho, zomwe zimapangitsa kuti chikhale chinthu choyenera kugwiritsidwa ntchito chomwe chimafuna kugwedezeka kwambiri kapena kugwedezeka kwambiri. N'zotheka kupeza kuuma kwakukulu ndi chitsulo cha kaboni wambiri, ndipo chitsulocho chidzakhala chokana bwino kulowa. Komabe, kuchuluka kwa kusweka kudzakhala kofulumira poyerekeza ndi mbale ya alloy yokonzedwa ndi kutentha chifukwa chitsulo cha kaboni wambiri chimakhala chofooka, kotero tinthu tating'onoting'ono tingang'ambike mosavuta kuchokera pamwamba. Chifukwa chake, zitsulo za kaboni wambiri sizigwiritsidwa ntchito pogwiritsidwa ntchito pogwedezeka kwambiri.
