FAQ
Q: Puas yog SA387 Qib 22 Chav Kawm 2 muaj zog dua li Chav Kawm 1?
A: Yog lawm, SA387 Qib 22 Chav Kawm 2 muaj zog dua li Chav Kawm 1. Thaum ob qho tib si sib xyaw cov tshuaj muaj pes tsawg leeg (2.25% Chromium thiab 1% Molybdenum), lawv tau txais kev kho cua sov sib txawv, ua rau cov khoom sib txawv.
Q: Qhov twg yog qhov zoo dua rau cov tshuab reactors: SA387 Qib 22 Chav Kawm 1 lossis Chav Kawm 2?
A: Rau refinery reactors-tshwj xeeb yog hydrocrackers thiab lwm yam siab -kub / siab- cov hlab ntsha siab -SA387 Qib 22 Chav Kawm 2 yog qhov kev xaiv zoo dua.
Q: Puas SA387 Qib 22 Chav Kawm 1 tuaj yeem hloov kho mus rau Chav Kawm 2 los ntawm kev kho cua sov?
A: Yog lawm, SA387 Qib 22 Chav Kawm 1 feem ntau tuaj yeem hloov kho mus rau Chav Kawm 2 los ntawm kev kho cua sov. Txij li thaum ob chav kawm sib koom tib cov tshuaj muaj pes tsawg leeg, lub zog tensile thiab yield zog ntau dua ntawm chav kawm 2 yog ua tiav los ntawm quenching thiab tempering los yog ceev txias, ua raws li tempering.
