ST37 Koyilo yachitsulo ya carbon

Pickling mbale imapangidwa ndi pepala lapamwamba kwambiri lopiringizidwa ndi kutentha ngati zopangira. Pambuyo pa pickling unit kuchotsa wosanjikiza okusayidi, chepetsa ndi kumaliza, pamwamba khalidwe ndi ntchito zofunika (makamaka ozizira mawonekedwe kapena masitampu ntchito) ali pakati otentha-anagulung'undisa ndi ozizira adagulung'undisa mankhwala wapakatikati pakati mbale ndi m'malo abwino m'malo mwa mbale otentha anagulung'undisa ndi ozizira adagulung'undisa mbale. Poyerekeza ndi mbale zotentha, ubwino waukulu wa mbale zoziziritsa ndi izi: 1. Ubwino wa pamwamba. Chifukwa mbale zoziziritsa zotentha zimachotsa sikelo ya oxide pamwamba, chitsulo chimakhala bwino, ndipo ndichosavuta kuwotcherera, kupaka mafuta ndi kupenta. 2. The dimensional kulondola ndi mkulu. Pambuyo kusanja, mbale mawonekedwe akhoza kusinthidwa kumlingo, potero kuchepetsa kupatuka kwa kusamvana. 3. Sinthani kumapeto kwa pamwamba ndikuwonjezera mawonekedwe. 4. Iwo akhoza kuchepetsa kuipitsidwa kwa chilengedwe chifukwa owerenga amwazikana pickling. Poyerekeza ndi mapepala ozizira ozizira, ubwino wa mapepala osakaniza ndikuti amatha kuchepetsa mtengo wogula ndikuwonetsetsa zofunikira za pamwamba. Makampani ambiri ayika patsogolo zofunikira zapamwamba komanso zapamwamba pakuchita bwino komanso mtengo wotsika wachitsulo. Ndi kupita patsogolo kosalekeza kwa teknoloji yopukutira zitsulo, ntchito ya pepala yotentha yotentha ikuyandikira ya pepala lozizira, kotero kuti "m'malo mwa kuzizira ndi kutentha" kumazindikiridwa mwaukadaulo. Tikhoza kunena kuti mbale ya pickled ndi mankhwala omwe ali ndi chiŵerengero chapamwamba cha ntchito ndi mtengo pakati pa mbale yozizira ndi mbale yotentha yotentha, ndipo ali ndi chiyembekezo chabwino cha chitukuko cha msika. Komabe, kugwiritsa ntchito mbale zoziziritsa kukhosi m'mafakitale osiyanasiyana m'dziko langa kwangoyamba kumene. Kupanga mbale zoziziritsa zaukatswiri kudayamba mu Seputembala 2001 pomwe njira yopangira pickling ya Baosteel idayamba kugwira ntchito.
