Okpomọkụ ọgwụgwọ nke ígwè

Ngwọta okpomọkụ nke ígwè n'ozuzu gụnyere quenching, tempering na annealing.Ngwọta okpomọkụ nke ígwè na-emetụta njirimara nke ihe ígwè.

1, Quenching: Quenching bụ ikpo ígwè na 800-900 degrees, na-ya ruo oge ụfọdụ, na mgbe ahụ ngwa ngwa ajụkwa ya na mmiri ma ọ bụ mmanụ, nke nwere ike melite ike naeyi iguzogide ígwè, ma na-amụba brittleness nke ígwè.

Ọnụọgụgụ jụrụ oyi na-ekpebi mmetụta nkwụsị.Ngwa ngwa jụrụ oyi, nke dị elu nke ike na iyi nguzogide nke ígwè, ma ọ ka ukwuu na brittleness.Ngwongwo na-emenyụ nke ígwè na-abawanye site na mmụba nke ọdịnaya carbon.The ígwè nwere carbon ọdịnayaN'okpuru 0.2% enweghị ike imenyụ ma sie ike.

Mgbe a na-ejikọta ọkpọkọ ahụ na flange, okpomọkụ dị nso na weld bụ ihe na-emenyụ, nke nwere ike ime ka ọ sie ike.Otú ọ dị, obere carbon ígwè nwere carbon ihe na-erughị 0.2% agaghị esi ike site quenching, nke bụ otu n'ime ihe mere obere carbon ígwè nwere ezi weldability.

2. Iwe ọkụ: ígwè a na-emenyụ emenyụ na-esi ike ma na-agbaji agbaji, ọ na-ebutekwa nchekasị n'ime.Iji belata nrịkasi ike a siri ike ma wepụ nrụgide dị n'ime ya, a na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ n'okpuru 550 Celsius C, wee mee ka ọ dị jụụ mgbe nchekwa ọkụ na-eme ka ọ dịkwuo mma na plasticity nke ígwè ahụ ma mezuo ihe achọrọ maka iji ya.

3. Na-ewe iwe: Iji belata ike ma melite plasticity nke ígwè, ikwado nhazi, ma ọ bụ wepụ ike brittleness na esịtidem nchegbu eme n'oge jụrụ na ịgbado ọkụ, ígwè nwere ike kpụ ọkụ n'ọnụ ruo 800-900 degrees, na nwayọọ nwayọọ mma mgbe okpomọkụ nchekwa ka. izute ihe achọrọ maka ojiji.Dịka ọmụmaatụ, ígwè na-acha ọcha annealed na 900-1100 degrees nwere ike ibelata ike na nhịkọ ma nweta malleability.
