Kev Ceeb Toom Rau Kev Ncaj Ncees Siab Boiler Tubes Thaum Ntxov

Raws li GB5310 high-pressure boiler raj thaum lub sij hawm quenching los yog tempering txheej txheem, kev sib xyaw ntawm thermal stress thiab lub koom haum kev ntxhov siab ua rau GB5310 high-pressure boiler raj rau deform. Ntawm lawv, kev hloov pauv ntawm cov ntaub so ntswg yog siv los ua kom tsim nyog ncaj. Cov txheej txheem no yog qhov yooj yim heev thiab tuaj yeem tau txais txiaj ntsig zoo.

1. Thaum cov txheej txheem kub straightening steel yog quenched, GB5310 high-pressure boiler raj yog txias rau "ze li 9 teev, thiab cov austenite tsis hloov mus rau martensite. Ua kom zoo dua plasticity ntawm austenite;

2 Cov residual GB5310 high-pressure boiler raj stabilized straightening txoj kev siv ib tug loj npaum li cas ntawm residual austenite yuav tsum tau khaws cia tom qab quenching, thiab ces txias straightened.

3. Lub zos ceev ceev cua txias txoj kev ncaj qha ua rau cov deformed pob kom sai txias thiab ntsws. Qhov kub tsis tuaj yeem qis dua qhov kub ntawm Ms, thiab kev hloov pauv martensitic tshwm sim;

4. Txoj kev tempering xeev straightening siv ib tug tshwj xeeb tempering fixture los yog pressurized straightening.
