Steel Heat lapaʻau e e lawe mai i loko o kekahi mau aoao. Poe akamai i maopopo ma waena o nā kēia mau koho:

1. kī pūʻana.

2. Normalization.

3. hoopaakiki ana.

4. haʻalele.

Heat lapaʻau o ke kila calcination huahana mea wela i ka wela o ka 840 a hiki i 900 degere. Ma keia wela, waiū ua lawe mai no ma ka liʻiliʻi loa, elua no hora, anuanu maila 'i me ke kapuahi wahi.

Steels ma keia ano ua hoʻohana 'ia i loko o ka hana o nā huahana ua hui ole ia i ka pono no ka hou huahana ku i ka hikiwawe i hala pilikia. Ma unfired au mamuli o ka mea hope ana wela keiki ke hana mawae mea e alakai i ka heterogeneity ma ka mea hiki ke hooheheeia 'ole.

Heat iapaau ana o ke kila ma normalizing māhele hoi he hahana maoli nō kēia, e ka mea i makemake mahana a me ka huʻihuʻiʻana iā lākou i loko o ka ea.

Hui o ka wela a me ka kokololio ka huʻihuʻiʻana. Oia ka manawa i wela iapaau ana hoʻi i nā kalapona kila a me kekahi mau oka a metala? Ueo. E like me ka hopena o ia 'ole nei i ka loli o ke aniani puka olu oia o ka mea - ka mea loaʻa iā ia kekahi i oi aku ka popopo ia'ku a me ka paakiki. A hiki i ka maʻiʻo o kalapona i loko o ke kila i ia 0,3% hui ua i hana. Ka paio hahana maoli nō ka mahana hoi Nāna e koho i kaukaʻi wale ma luna o ka papa 'o ka mea hiki ke hooheheeia. Nui loa ka mea i kā mākou allowable mahana ( "perezhig") e 'ai pono i loko o ka poho o kona kila waiwai. I ka hopena o ka loa mare.

E pale aku māhele liʻiliʻi perezhiga pili preheated ku (ke keʻena luna). Rapid huahana anuanu maila 'hoʻolako i ka hui paa. E like me ka hopena, ka mea i hana i ka nui maloko stress, ma kekahi hihia, a he mau māwae,. Eia naʻe, ina koi 'ia ma ka lohi anuanu hui paakiki hiki ole ke loaa.

Like anuanu meakino ka wai ua hoʻohana 'ia, ka aila, ea a he koʻana koko pāʻoihana. Salt (papu), nitrate paha paʻakai hydroxide, hou i ka coolers, hiki hōʻeleu i ke anuanu maila '. I mea e emi i ke anuanu ana i loko o ka wai ua hou i ka pāʻoihana o ke kopa, aniani wai, he aila emulsion, ka waiu o ka Lime a me nā eiiiiiaiou.

Ma sequential poe paakiki, ai iiiaanoaa o 'atikala ia he nui ka moku a me ka pinepine ia loli o ka wai. Ma ia ano i kekahi hihia, e hāʻawi 'ia i kaʻaʻahu pio ole.

Ka mea, oia ke hookaawale? Ueo thermochemical kanaka o ke kila. Kēia kaʻina hiehie i ka hopena o ka mahana a me saturation o kaʻili a me ka 'ē aʻe metala hehee ai. Kēia hana i ka mea hiki ke hoʻololi i ka Nine Inch haku mele 'ana, ka waiwai a me ka microstructure o ka ili honua papa o ka mea.

Nine-thermal hookoia nā nitriding, carburizing, aluminizing, cyanidation, siliconizing a me nā ki ina hana like.
