Lub ntsiab lus tseem ceeb twg yog qhov tseem ceeb tshaj plaws nyob rau hauv tempering nkhaus ntawm H13 khoom?

Qhov kub thiab txias yog qhov tseem ceeb tshaj plaws hauv cov khoom siv H13 tempering nkhaus. Qhov sib npaug ntawm cov pwm qhov toughness thiab hnav tsis kam tuaj yeem cuam tshuam ncaj qha los ntawm qhov sib txawv ntawm qhov kub thiab txias ntawm ntau tshaj ± 5 degree, uas tuaj yeem ua rau lub hardness hloov ntawm 1 ~ 2 HRC.

1. Vim li cas qhov tseem ceeb tshaj plaws yog qhov kub thiab txias? Factors & Yog vim li cas:

Hardness Teb: Ib qho kev hloov ntawm ± 10℃tuaj yeem ua rau lub hardness hloov ntawm 1 ~ 2 HRC nyob rau hauv 550 ~ 600℃ntau yam. Qhov kev pheej hmoo yog mus txog thaum qhov kev pom zoo ntau dhau.

Critical Microstructure Transformation: Tsawg kub (<550°C) result in inadequate tempering, which leaves behind high brittleness and residual high-carbon martensite. Overheating (>600 degree) ua rau dhau-tempering, carbide coarsening, thiab poob zog.

Qhov cuam tshuam tseem ceeb: Qhov teeb meem tswj qhov kub thiab txias ua rau lub tuam txhab teeb tsa qhov kub thiab txias rau 530 degree, ua rau cov ntaub ntawv hardness ntawm 53.5 HRC. Tom qab tsuas yog peb hnub online, qhov tawg tawg tau tshwm sim.

Txhawm rau lav lub qhov cub kub qhov sib txawv ntawm Tsawg dua lossis sib npaug li ± 5 degree, qhov pom zoo tswj qhov rais yog 580℃± 5 degree, ua ke nrog ntau - taw tes ntsuas kub thiab PID ntsuas kub.

PID kub tswj thiab ntau- taw tes ntsuas kub yog siv los xyuas kom meej lub qhov cub kub qhov sib txawv ntawm Tsawg dua lossis sib npaug rau ± 5℃. Qhov pom zoo tswj qhov rais yog 580 degree.

3. Yuav ua li cas ntsuas kub - Cov ntsiab lus rhiab heev yuav raug tswj tau?

Thaum siv PID kub tswj qhov system, xyuas kom meej qhov sib txawv ntawm qhov tseeb thiab teeb tsa qhov tseem ceeb tsawg dua lossis sib npaug li ± 5 degree.

Multi- ntsuas qhov ntsuas qhov ntsuas kub ntsuas: Teeb yam tsawg kawg peb qhov ntsuas qhov ntsuas kub hauv lub qhov cub sab sauv, nruab nrab, qis, thiab kaum ntu;

Kev ntsuas cov cuab yeej nquag: Tshawb xyuas qhov ntsuas kub thiab ntsuas kub txhua peb lub hlis;
