nkọwa:

Na-ekpo ọkụ: Iji wedata mgbagha na ngwaọrụ dị mgbagwoju anya jiri preheat okpukpu abụọ. Kpoo ọkụ na ọnụego agaghị agafe 400ºF kwa elekere (222°C kwa elekere) ruo 1150-1250°F (621-677°C), haha ​​nhata, wee bulie ya na 1500-1600°F (816-871°C) na hazie. Maka ngwaọrụ nkịtị, jiri naanị oke okpomọkụ nke abụọ dị ka otu ọgwụgwọ ikpo ọkụ.

Ịkwado (Ọkụ dị elu): Kpoo ọkụ ngwa ngwa site na preheat. Ọkụ ma ọ bụ Nnu: 1800-1890°F (982-1032°C) Maka ike siri ike, jiri 1800°F (982°C) Maka ike siri ike na iguzogide ike ọgwụgwụ okpomọkụ na iyi jiri 1890 (1032°C). Tinye na okpomọkụ maka nkeji 30 ruo 90.

Na-emenyụ: Ikuku, gas na-akpa ike, ma ọ bụ mmanụ ọkụ. Ọkpụrụkpụ nke ngalaba ruo na gụnyere inch 5 (127 mm) ga-esikarị ike kpamkpam mgbe ikuku dị jụụ site na ọgwụgwọ na-enyere aka. Akụkụ karịrị inch 5 (127 mm) n'ogo ga-achọ ka ọ dị ngwa ngwa site na iji ikuku mmanye, gas na-arụ ọrụ, ma ọ bụ nkwụsị mmanụ na-akwụsị iji nweta ike siri ike, ike na iguzogide ike ọgwụgwụ ọkụ.

Maka mmenyụ ikuku nke nrụgide, a na-achọ opekempe nkwụsị nke ihe dị ka 50°F kwa nkeji (28°C kwa nkeji) ruo n'okpuru 1000°F (538°C) iji nweta ihe kacha mma na nchara.

Maka mmanụ, menyụọ ruo oji, ihe dị ka 900°F (482°C), wee dị jụụ n'ikuku ruo 150-125°F (66-51°C).

Advantage:

1.High hardenability na siri ike

2.Great nguzogide maka ikpo ọkụ ọkụ

3.The secondary hardening ike na tempering dị njọ n'ihi na ya ala carbon ọdịnaya

4.The deformation bụ obere mgbe okpomọkụ ọgwụgwọ

5.Good machinability.
