Yuav ua li cas kuaj qhov zoo ntawm kub dov seamless steel yeeb nkab?

1. Kev tshuaj xyuas zoo ntawm cov txheej permeable thiab cov tub ntxhais. Xyuas seb lub zog ntawm qhov chaw thiab cov tub ntxhais ua tau raws li cov qauv kev qhia, seb qhov kev taw qhia gradient ntawm kev siv zog ntawm qhov chaw mus rau sab hauv puas zoo, thiab seb lub zog saum npoo puas zoo ib yam;

2. Txheeb xyuas qhov hloov pauv thiab tawg ntawm cov yeeb nkab kub dov seamless. Seamless steel yeeb nkab uas tau txiav tom qab nitriding, kev kho cua sov thiab quenching tuaj yeem tsim thiab ua tiav tam sim yog tias cov duab sib txawv nyob rau hauv qhov kev teev tseg. Rau deformation deviations, straightening yuav tsum tau ua. Cracked seamless steel kav feem ntau yog tawg thiab daws tam sim ntawd.

3. Raw khoom soj ntsuam ntawm kub dov seamless yeeb nkab. Ntxiv nrog rau kev txheeb xyuas muaj pes tsawg leeg, nws tseem yuav tsum tau kuaj xyuas qhov tsis xws ntawm cov sawb mechanism, cov ntaub ntawv tsis yog hlau, impurities, tawg thiab lwm yam mechanisms;

4. Tshawb xyuas qhov kev faib tawm thiab qib kev txheeb xyuas ntawm cov qauv metallographic ntawm lub plawv;

5. Permeation txheej zoo soj ntsuam. Xws li carburized txheej qhov tob 1. Carbon concentration tus nqi ntawm carburized txheej, cementite faib, khaws cia martensite, austenite morphology thiab nws qib kev txheeb xyuas, thiab lwm yam.
