Nrog rau txoj kev loj hlob sai ntawm Tuam Tshoj txoj kev lag luam roj, qhov kev thov rau qib high-qib steel yog loj hlob, thiab high-qib steel yuav tsum tau quenched, thiab yog li ntawd txoj kev kawm ntawm tag nrho cov quenching ntawm steel yog ib qho tseem ceeb heev. Tuam Tshoj Heavy Machinery Research Institute tau tsim ib qho "dip quenching + internal spray + spin" thiab "sab nraum lub dav hlau da dej + spin" ob txheej txheem, thiab kev tshawb fawb thiab kev loj hlob muaj feem xyuam rau quenching kab, thiab ua tiav cov txiaj ntsig zoo. Ob leeg txheej txheem quenching muaj nws tus yam ntxwv, sab nraum da dej sab hauv dav hlau quenching ntau lawm kab yog tsim rau roj zoo kav, roj casing, laum yeeb nkab quenching, ntau conducive rau tag nrho cov quenching nyias phab ntsa steel raj; immersion quenching ntau lawm kab yog tsim rau phab ntsa thickness sib piv Great zuag qhia tag nrho hardening siab kev kawm tuab-walled raj, thiab nws cov khoom yog tsuas yog siv nyob rau hauv lub teb chaws tiv thaiv, nuclear zog, roj thiab roj thiab automotive industries.

Immersion quenching ntau lawm kab
Cov khoom siv quenching hauv tsev tam sim no siv, muaj qee qhov tuab-walled tube tsis xws luag, xws li (1), tuab-walled yeeb nkab khoov yooj yim quenched, ncaj, roundness tsis zoo, mus rau tom ntej shaping ua rau nyuaj; (2) cov yeeb nkab sab hauv thiab sab nraud tsis tuaj yeem quenched, ua rau Markov lub cev cov ntsiab lus yog tsawg, tsis sib xws hardness; (3) cov nqi khiav lag luam siab, kev ruaj ntseg tsis zoo. Hauv kev teb rau cov kev tsis txaus no, lub tsev kho mob ywj pheej tshawb fawb thiab kev tsim kho, ua tiav cov txheej txheem tsim khoom hauv ntiaj teb thawj zaug siv "immersion quenching + Rotate + inner spray" quenching steel yeeb nkab phab ntsa thickness tshaj 20 hli los ntawm tag nrho cov immersion quenching quenching quenching ntau lawm kab. Cov txheej txheem txoj kev yog: hardened steel rauv cua sov khoom → tuaj txog gauge mounted ntawm lub nqa ceev rotating txhais tau tias nias txhais tau tias nias lub txhawb log tsav steel yeeb nkab → nyob ib ncig ntawm ceev rotating lifting cylinder tsav lub steel ncej beam sai immersion quenching nyob rau hauv dej → nyob rau hauv cov tshuaj tsuag nozzle mus rau sab hauv ntawm cov yeeb nkab steel txhaj tshuaj → quenching kawg, nyob rau hauv lub tshuaj tsuag nres → hais txog lifting lub tog raj kheej yuav nce steel ncej kab teeb → scroll kom tsis txhob pub cov cuab yeej ntawm cov khoom noj los ntawm kev thaiv-los-tig mus rau hauv paus ntawm cov dej khoob. yeeb nkab bracket → Cov dej khoob txhais tau hais tias tsa ib kawg ntawm cov yeeb nkab tau lifted ntxiv tshuab compressed cua quenching dej → dej → stepping conveyor yeeb nkab nyob rau hauv cov yeeb nkab maj mam thauj mus rau feed rollers → tiav hardening hlau. Qhov no immersion quenching quenching unit thawj zaug siv "immersion quenching + Rotate + inner spray" tshiab thev naus laus zis rau txoj kab uas hla loj, tuab-walled raj zuag qhia tag nrho quenching daws cov kab loj tuab tuab-walled yeeb nkab khoov quenching, quenching impervious technical teeb meem; Peb ua tiav cov txiaj ntsig tseem ceeb hauv qab no: (1) Vim tias tag nrho qib ntawm cov yeeb nkab dej, kev sib hloov ceev ceev, kev txhawb nqa ntau lub ntsiab lus, yog li txhim kho qhov ncaj ntawm cov hlau, tsawg dua 2 hli / m, ua tau raws li qhov yuav tsum tau ua. cov khoom. (2) siv cov kev sib hloov ua haujlwm nyob rau hauv lub xov tooj txawb nozzle, txo cov yeeb nkab ovality taub hau conducive yeeb nkab sizing. (3) Nrog txav quenching nyob rau hauv quenching txheej txheem ntau saj zawg zog, ntau yam txhua yam khoom ntawm cov hlau, tom qab quenching martensite conversion tus nqi ntawm ntau tshaj 90%, txawm 95%, hardness thiab thickness kev taw qhia ntawm tag nrho-ntev steel yeeb nkab yuam kev ntawm ≤ 3 HRC.

"Txaus + sab nraum da dej + sab hauv spin" txheej txheem quenching.
Cov txheej txheem no yog cov phab ntsa nyias nyias rau cov yeeb nkab. Hardened steel rauv rhuab mus txog 1000 ℃, pub cov menyuam rau txoj hauj lwm yuav tsum tau, cov khoom noj khoom noj nqa steel tig nws mus rau qhov qeeb qeeb txhais tau tias tig lub log txhawb nqa, lub siab mounted ntawm cov tshuaj tsuag khib nrawm nrawm txhais tau tias nias cov yeeb nkab, rotary tsav txhais tau hais tias ceev ceev tig ceev ceev rotating steel yeeb nkab, steel yeeb nkab yog nyob ncaj qha rau saum npoo ntawm lub raj xa dej mus rau ib qho kev sib txawv ntawm cov yeeb nkab sprinkler, thaum cov tshuaj tsuag txhais tau tias ntsia rau hauv cov yeeb nkab kawg ntawm cov yeeb nkab phab ntsa mus rau lub taub hau tshuaj tsuag. Yog li cov sab hauv thiab sab nrauv ntawm cov yeeb nkab steel tau zoo ib yam quenching.
