Dab tsi yog cov txheej txheem annealing rau high zaus annealing tshuab

1. Tsis tiav annealing: Tsis tiav annealing yog kom sov cov hlau-carbon alloy mus rau nruab nrab kub ntawm Ac1-Ac3 kom ua tiav martensitization tsis tiav. Nrog cov txheej txheem annealing ntawm qeeb txias. Tus yuam sij rau kev ua tsis tiav annealing yog tsim rau nruab nrab thiab 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 tsawg dua los yog siab dua Ac1 me ntsis los yog hloov qhov kub nyob ib ncig ntawm A1 rau ib lub sij hawm, thiab ces maj mam txias. Spheroidizing annealing yog siv los txo lub siab toughness ntawm alloy steel thiab 45 steel tom qab casting;

3. Isothermal annealing: siv los txo lub siab toughness ntawm qee cov cuab yeej alloy steels nrog ntau dua nickel thiab chromium Cheebtsam los nqa tawm drilling ntau lawm thiab ua;

4. Nthuav annealing: tuab dhau-kub mechanism nrog lub cev tsis zoo tom qab forging, casting thiab hluav taws xob vuam ntawm high-carbon steel;

5. In-situ stress relief annealing: siv los tshem tawm cov thermal stress ntawm steel castings thiab weldments;

6. Sab nraud diffusion annealing: siv los sib npaug ntawm cov txhuas alloy castings thiab txhim kho lawv cov kev ua tau zoo;

7. Ua haujlwm hardening annealing: siv los tshem tawm qhov nyuaj hauv qab ntawm cov hlau xaim thiab cov ntawv hlau thaum lub sij hawm tag nrho cov txheej txheem ntawm kev kos duab txias thiab txias dov, thiab tshem tawm cov cua txias ua hauj lwm hardening los ua cov ntaub ntawv hlau mos.

8. Graphitization annealing: high-frequency annealing tshuab yog siv los hloov npua hlau nrog ntau cementite rau hauv malleable cam khwb cia hlau nrog zoo heev yas deformation. Tom qab tau rhuab mus rau ib tug tej yam kub, rwb thaiv tsev kub thiab kub preservation rau ib tug tej lub sij hawm ntawm lub sij hawm thiab ces txias txias, thiaj li hais tias cov cementite yog yaj los tsim high-purity graphite floccules.

Tag nrho cov nyob rau hauv tag nrho cov, lub high-frequency annealing tshuab yuav txo tau lub zog, txhim kho cov kev ua tau zoo ntawm drilling txheej txheem, maj mam sov cov hlau cov ntaub ntawv rau ib tug tej yam kub thiab txias, khaws cia rau ib tug zoo lub sij hawm thiab txias nws nyob rau hauv ib tug nruab nrab tus nqi kom txo tau tus nqi. zog.
