(2) Kev kuaj tsis muaj kev puas tsuaj kev tshuaj xyuas:

ib.Ultrasonic flaw detection UT: Nws yog rhiab rau saum npoo thiab sab hauv tawg tsis xws luag ntawm ntau yam ntaub ntawv nrog cov ntaub ntawv zoo li qub.
b.Eddy tam sim no kuaj ET (electromagnetic induction) yog qhov tseem ceeb rau qhov taw tes (lub qhov zoo li) qhov tsis xws luag.
c.Sib Nqus Particle MT thiab Flux Leakage Testing: Kev ntsuam xyuas hlau nplaum yog tsim rau kev tshawb nrhiav ntawm qhov chaw thiab qhov ze ntawm qhov chaw ntawm cov khoom ferromagnetic.
d.Electromagnetic ultrasonic flaw detection: Tsis muaj qhov nruab nrab coupling yog yuav tsum tau, thiab nws yuav siv tau rau high-temperature, high-ceev, ntxhib steel yeeb nkab nto flaw detection.
e.Penetrant flaw detection: fluorescence, coloring, nrhiav pom ntawm steel yeeb nkab defects.

3. Tshuaj ntsuam xyuas muaj pes tsawg leeg:tshuaj ntsuam xyuas, ntsuas ntsuas (infrared CS ntsuas, nyeem ncaj qha spectrometer, TSIS ntsuas ntsuas, thiab lwm yam).

(1) Infrared CS ntsuas: Ntsuam xyuas ferroalloys, steelmaking raw cov ntaub ntawv, thiab C thiab S ntsiab nyob rau hauv steel.
(2) Direct nyeem ntawv spectrometer: C, Si, Mn, P, S, Cr, Mo, Ni, Cn, Al, W, V, Ti, B, Nb, As, Sn, Sb, Pb, Bi hauv cov qauv ntau.
(3) N-0 ntsuas: roj cov ntsiab lus tsom xam N, O.

4. Kev tswj xyuas kev ua tau zoo ntawm cov hlau

(1) Tensile test: ntsuas kev ntxhov siab thiab deformation, txiav txim siab lub zog (YS, TS) thiab plasticity Performance index (A, Z) ntawm cov khoom.Longitudinal thiab transverse qauv yeeb nkab seem, arc puab, ncig qauv (￠10, ￠12.5) me me txoj kab uas hla, nyias phab ntsa, loj txoj kab uas hla, tuab phab ntsa calibration nrug.Lus Cim: Qhov elongation ntawm tus qauv tom qab tawg yog cuam tshuam nrog qhov loj ntawm tus qauv GB / T 1760
(2) Impact test: CVN, notch C type, V type, work J value J/cm2 standard sample 10 × 10 × 55 (mm) non-standard qauv 5 × 10 × 55 (mm).
(3) Hardness test: Brinell hardness HB, Rockwell hardness HRC, Vickers hardness HV, thiab lwm yam.
(4) Hydraulic xeem: ntsuas siab, lub sijhawm ruaj khov, p = 2Sδ / D.

5. Seamless steel yeeb nkab txheej txheem kev soj ntsuam

(1) Flattening test: ncig qauv C-zoo li tus qauv (S / D> 0.15) H = (1 + 2) S / (∝ + S / D) L = 40 ~ 100mm, deformation coefficient ib chav tsev ntev = 0.07 ~ 0.08
(2) Nplhaib rub kuaj: L = 15mm, tsis muaj qhov tawg yog tsim nyog
(3) Flaring thiab curling xeem: qhov nruab nrab taper yog 30 °, 40 °, 60 °
(4) Bending test: Nws tuaj yeem hloov qhov kev sim flattening (rau cov kav dej loj)

6. Metallographic tsom xam ntawm seamless yeeb nkab
High magnification test (microscopic analysis), low magnification test (macroscopic analysis) tower-shaped hairline test to analyze the grain size of non-metallic inclusions, display low-density tissues and defects (xws li looseness, segregation, subcutaneous bubbles, etc. ), thiab tshuaj xyuas tus naj npawb, qhov ntev thiab kev faib tawm ntawm cov plaub hau.

Tsawg-magnification qauv (macro): Pom pom cov pob dawb, suav nrog, cov npuas subcutaneous, cov tawv nqaij tig thiab delamination tsis raug tso cai nyob rau ntawm qhov qis-magnification tshuaj xyuas cross-sectional acid leaching test pieces ntawm seamless steel kav.

Lub koom haum siab zog (microscopic): Tshawb xyuas nrog lub tshuab hluav taws xob hluav taws xob siab.Ntauwd hairline test: kuaj tus naj npawb, ntev thiab faib cov plaub hau.

Txhua batch ntawm seamless steel kav nkag mus rau hauv lub Hoobkas yuav tsum tau nrog ib tug zoo daim ntawv pov thawj ua pov thawj qhov ncaj ncees ntawm cov ntsiab lus ntawm batch ntawm seamless steel kav.
