Dab tsi yog cov txheej txheem annealing high zaus annealing tshuab

1. Incomplete annealing: Incomplete annealing yog txheej txheem annealing uas cov hlau-carbon alloy yog rhuab mus rau nruab nrab kub ntawm Ac1-Ac3 kom ua tiav martensitization tsis tiav, ua raws li los ntawm qeeb txias. Tsis tiav annealing yog tsim rau nruab nrab, nruab nrab carbon steel thiab siab alloy steel forgings, thiab lwm yam .;

2. Spheroidizing annealing: cua sov cov hlau mus rau qhov kub me ntsis qis dua lossis siab dua Ac1 lossis hloov qhov kub ntawm A1 rau ib lub sijhawm, thiab maj mam txias. Spheroidizing annealing yog siv los txo lub siab toughness ntawm alloy steel thiab No. 45 steel tom qab casting;

3. Isothermal annealing: siv los txo qhov siab toughness ntawm qee cov cuab yeej alloy steels nrog cov nickel thiab chromium siab los ua kom tiav drilling ntau lawm thiab ua haujlwm;

4. Kev sib xyaw ua kom zoo: lub zog ruaj khov tshaj qhov ntsuas kub nrog lub cev tsis zoo tom qab forging, casting thiab hluav taws xob vuam ntawm cov pa roj carbon siab;

5. Kev ntxhov siab hauv av annealing: siv los tshem tawm thermal kev nyuaj siab ntawm steel castings thiab weldments;

6. Sab nraud diffusion annealing: siv los ua homogenize ntawm aluminium alloy castings thiab txhim kho lawv cov ntsuas kev ua tau zoo;

7. Ua hauj lwm hardening annealing: Nws yog siv los tshem tawm lub hardened xeev ntawm hlau hlau thiab hlau los xij nyob rau hauv tag nrho cov txheej txheem ntawm txias txias thiab txias dov, thiab tshem tawm cov txias ua hauj lwm hardening nyhuv kom soften cov ntaub ntawv hlau.

1. Graphitization annealing: Lub tshuab ua haujlwm siab ntau yog siv los tig npua hlau nrog ntau cov cementite rau hauv malleable cam khwb cia hlau nrog zoo heev yas deformation. Tom qab cua sov rau ib qho kub, rwb thaiv tsev kub rau ib lub sij hawm ntawm lub sij hawm thiab ces txias txias, thiaj li hais tias cov cementite dissolves los tsim flocculent high-purity graphite.
