Ka 'ike o ka wili 'ilikai hana opaipu kila kila:
1. Ma hope o ka ʻōwili wela, ka hoʻopili ʻana, ka ʻili ʻana, a me ka hoʻohaʻahaʻa ʻana, ʻo ka ʻili o ka pā kila kuhili ʻole i mālama ʻia he ʻili ʻeleʻele a ʻano ʻano ʻinoʻino;
2. He kaʻina hana ʻoi aku ka maikaʻi ma mua o ka ʻili maʻamau, a ʻo ia hoʻi kahi ʻili ʻeleʻele. Ma hope o ka ʻōwili anu, hoʻopili, hoʻoheheʻe ʻia, a ma hope o ka ʻōwili māmā ʻana me kahi ʻōwili ʻōpala;
3. ʻO kēia ka mea maʻamau i hoʻohana ʻia i nā noi kūkulu. Ma waho aʻe o ka ʻōwili anu mālie hope loa me ka roller polishing ma hope o ka annealing a me ka descaling, ua like nā kaʻina hana ʻē aʻe me 2D, ʻālohilohi iki ka ʻili, a hiki ke hoʻoliʻi ʻia;
4. Alohilohi annealing:
(a) He ʻili hoʻomanaʻo kēia, i ʻōwili ʻia e nā ʻōwili polishing a hoʻopaʻa hope ʻia i loko o kahi lewa i hoʻomalu ʻia;
(b) Mālama mau ka annealing mālamalama i kona ʻili hoʻomanaʻo a ʻaʻole ia e hana i kahi unahi oxide.
