Tam sim no, cov kav hlau steel tau siv dav thiab muaj ntau hom. Thermal expansion carbon steel yeeb nkab yog ib qho ntawm lawv. Nws muaj ntau yam zoo, tab sis ntawm chav kawm nws tsis yog tsis muaj qhov tsis zoo. Cov hauv qab no yog cov lus piav qhia ntxaws txog qhov zoo thiab qhov tsis zoo ntawm cov kav dej kub-expanded steel los ntawmcarbon steel yeeb nkab manufacturers, vam tias yuav pab koj nkag siab cov khoom no.

Qhov zoo ntawmthermal expansioncarbon steel yeeb nkab:

Nws tuaj yeem rhuav tshem cov qauv forging ntawm cov yeeb nkab steel, kho qhov loj ntawm cov yeeb nkab uas muaj cua sov-expandable steel yeeb nkab, tshem tawm cov microstructure defects, ua rau cov cua sov-expandable steel yeeb nkab compact hauv cov qauv thiab txhim kho cov khoom siv kho tshuab. Qhov kev txhim kho no feem ntau yog xav txog hauv cov kev taw qhia dov, kom cov yeeb nkab uas muaj cua sov-expandable steel tsis muaj cov isotropy sib raug, thiab cov npuas, tawg thiab porosity generated nyob rau hauv cov txheej txheem pouring kuj yuav welded nyob rau hauv lub functionality ntawm kub thiab siab. .

Qhov tsis zoo ntawmthermal expansioncarbon steel yeeb nkab:

1. Kev ntxhov siab uas tshwm sim los ntawm qhov tsis sib xws. Residual stress yog hais txog kev ntxhov siab hauv tus kheej ntawm tus kheej tsis muaj zog. Cov kev ntxhov siab zoo li no muaj nyob hauv cov kav dej kub-expandable steel ntawm ntau qhov sib txawv. Feem ntau, qhov loj dua qhov loj ntawm seem steel, qhov ntau dua qhov seem ntawm qhov kev ntxhov siab. Residual stress yog ib txwm ua rau nws tus kheej-theem sib npaug, tab sis nws tseem muaj cov txiaj ntsig zoo ntawm cov yam ntxwv ntawm cov hlau hauv qab kev ua ntawm sab nraud quab yuam. Xws li kev deformation, tsis muaj kev ntxhov siab, qaug zog tiv thaiv, thiab lwm yam yuav muaj kev cuam tshuam tsis zoo.

2. Tom qab thermal expansion, cov non-metallic inclusions (tsuas yog tsim los ntawm sulfides thiab oxides thiab silicates) nyob rau hauv lub thermal expansion steel yeeb nkab yog nias rau hauv nyias los xij, uas ua rau delamination (interlayer). Delamination yuav ua rau lub zog tensile ntawm lub tshav kub-expandable steel yeeb nkab raws li thickness kev taw qhia, thiab thaum lub weld shrinks, interlaminar tearing yuav tshwm sim. Ib feem strain vim welding shrinkage feem ntau yog ob peb zaug ntawm yield point strain thiab ntau dua li ib nrab strain vim lub load.
