Txhawm rau kom txaus siab rau qhov zoo ntawm threaded steel tuav, cov kev txiav txim hauv qab no tuaj yeem kos.
1. Kev txheeb xyuas cov tshuaj muaj pes tsawg leeg
Cov ntsiab lus tsom xam ntawm C, Si, Mn, P, S, thiab lwm yam hauv Rebar
Cov tshuaj muaj pes tsawg leeg yuav tsum ua raws li ASTM, GB, DIN thiab lwm yam qauv.
2. Mechanical Performance Test
Tensile xeem qhia lub zog tensile, tawm lub zog, compression cheeb tsam, thiab lwm yam.
Rockwell lossis Vickers hardness test.
Cov txheej txheem kev ua tau zoo ntawm cov neeg kho tshuab tau teev tseg hauv cov qauv sib xws yuav tsum ua raws.
3. Kev kuaj xyuas hlau
Ua tib zoo saib cov qauv hauv metallographic analyzer los kuaj xyuas qhov tsis xws luag thiab cov qauv tsis zoo.
Qhov kev ntxhib los mos yuav tsum du, sib xws, tsis muaj kab nrib pleb thiab txawv teb chaws.
4. Tshawb xyuas qhov zoo ntawm lub vev xaib.
Visually soj ntsuam cov tsos, nto zoo, mechanical puas, tawg, dents, thiab lwm yam.
Ra yog siv rau qhov chaw roughness detection
5. Nrhiav lub ntsiab lus
Jigs thiab fixtures yog siv los xyuas cov tsis xws li hlau zoo, suab thiab tolerances.
Tshawb xyuas qhov tsis xws luag, kev puas tsuaj, deformation, thiab lwm yam.
Raws li lub teb chaws thiab cov qauv kev lag luam
6. Kev sim tsis muaj kev puas tsuaj
Ob qho tib si saum npoo thiab sab hauv yog kuaj los ntawm cov kua dej penetrant los yog magnetic particle method.
Yog li ntawd, seb qhov kev ntsuam xyuas tau ua tau raws li qhov yuav tsum tau ua ntawm cov qauv kev lag luam tuaj yeem ua qhov kev ntsuam xyuas zoo ntawm cov rebar.Qhov no yuav tsum tau siv cov cuab yeej kuaj tshwj xeeb thiab cov txheej txheem xeem.
