Paʻa kila kuhili ʻole wela

pono

Hot-rolled stainless steel he haʻahaʻa paʻakikī, hana maʻalahi a me ka ductility maikaʻi.

ʻO ka pā kila kila kila wela, ʻoi aku ka haʻahaʻa o nā waiwai mechanical i ka hana anu, a haʻahaʻa i ka forging, akā ʻoi aku ka paʻakikī a me ka ductility.

ʻO ka ʻokoʻa ma waena o ke kila kila kila a me kaʻōwili anu

ʻO kaʻokoʻa ma waena o ka'ōwili wela a me ka'ōwili anu o ke kila kila,ʻo ia ka'ōwili anu ma ke kumu o ka'ōwili wela.

ʻO ka'ōwili anuanu: Ua hanaʻia a'ōwiliʻia ma ke kumu o ke kila kila kila a me ka coil.ʻO ka ʻōlelo maʻamau, he kaʻina hana ia o ka ʻōwili wela → pickling → ka ʻōwili anuanu.ʻOiai e wela ka pā kila ma muli o ka ʻōwili ʻana i ka wā e hana ai, ua kapa ʻia ʻo ia ʻo ka ʻōwili anuanu.Ma muli o ka hoʻololi mau ʻana o ke anuanu o ka ʻōwili wela, ʻilihune nā waiwai mechanical a kiʻekiʻe loa ka paʻakikī.Pono e hoʻopili ʻia no ka hoʻihoʻi ʻana i kona mau waiwai mechanical, a ʻo ka poʻe me ka annealing ʻole i kapa ʻia nā ʻōwili paʻa.Hoʻohana mau ʻia nā ʻōwili paʻa paʻa e hana i nā huahana ʻaʻole pono ke kulou a hoʻopololei paha.

ʻO kāna mau hiʻohiʻona:

1. Ma muli o kekahi ʻano o ka paʻakikī o ka hana, he haʻahaʻa ka paʻakikī a ʻoi aku ka pipiʻi o nā pale kila i ʻōwili ʻia;

2. ʻAʻohe unahi oxide ka ʻili anuanu, a maikaʻi ka maikaʻi;

3. ʻO ka huahana i hana ʻia e ke anuanu deformation he kiʻekiʻe kiʻekiʻe ka pololei a me ka maikaʻi o ka ʻili;

4. Hoʻohana nui ʻia ka ʻōwili anu ma nā ʻano āpau o ke ola ma muli o kāna kaʻina hana, e like me nā ʻano mea a pau o nā ʻāpana hoʻoheheʻe anu, nā kiʻi extrusion anu i ʻōwili ʻia, nā pūnāwai anu, nā uwea huki anu, nā kī poʻomanaʻo anu, etc.

ʻO ka ʻōwili wela (ka ʻōwili wela): pili i ka ʻōwili anu, ke ʻōwili nei ka ʻōwili anu ma lalo o ka mahana recrystallization, a ke ʻōwili nei ka ʻōwili wela ma luna o ka wela o ka recrystallization.

ʻO kāna mau hiʻohiʻona:

1. Ua ilihune ka oolea a me ka palahalaha o ka ili, a ua emi ke kumukuai;

2. ʻO ka mahana o ka'ōwili wela ua like ia me ka forging;

3. Kapā welaua owili wela a he ili oxide ma ka ili, a he okoa ka manoanoa o ka papa;

4. Ma muli o kāna kaʻina hana, hoʻohana ʻia ia i nā noi kīwila he nui, e like me nā lako kīhini, nā mea hana hale maʻamau, etc.;

5. ʻO nā mea mechanical onā ʻili kila ʻōwili welaʻoi aku ka haʻahaʻa ma mua o ka hana anu a me ka forging, akā ʻoi aku ka maikaʻi o ka paʻakikī a me ka ductility.
