Feem ntau cov teeb meem ntawm cov neeg muag khoom thiab cov neeg siv khoom yog vim kev sib txuas lus tsis zoo. Kev coj noj coj ua, cov neeg muag khoom tuaj yeem tsis kam nug tej yam uas lawv tsis nkag siab. Peb rhuav tshem tag nrho cov teeb meem no kom ntseeg tau tias koj tau txais yam koj xav tau mus rau qib koj xav tau, thaum koj xav tau. Lub sijhawm xa khoom sai dua thiab cov khoom koj xav tau yog peb Cov Cai.

Daim ntawv thov
Nws yog tsuas yog siv los ua kom zoo seamless carbon steel, rau boiler kav, super kub kav
rau bolier kev lag luam, kub hloov yeeb nkab thiab lwm yam. Nrog qhov sib txawv qhov ntau thiab tsawg
Qib tseem ceeb
Qib ntawm high-zoo carbon boiler steel: GrA, GrC
Chemical Component
| Element | Qib A | Qib C |
| C | ≤ 0.27 | ≤ 0.35 |
| Mn | ≤ 0.93 | 0.29-1.06 Nws |
| P | ≤ 0.035 | ≤ 0.035 |
| S | ≤ 0.035 | ≤ 0.035 |
| Si | ≥ 0.1 | ≥ 0.1 |
A Rau txhua qhov kev txo qis ntawm 0.01% qis dua cov pa roj carbon siab tshaj plaws, qhov nce ntawm 0.06% manganese saum toj no qhov siab tshaj plaws yuav raug tso cai mus txog qhov siab tshaj ntawm 1.35%.
Mechanical Property
| Qib A | Qib C | |
| Tensile zog | ≥ 415 | ≥ 485 |
| Yield zog | ≥ 255 | ≥ 275 |
| Elongation tus nqi | ≥ 30 | ≥ 30 |
Kev Xeem Xeem
Hydraustatic Test:
Cov yeeb nkab steel yuav tsum tau sim Hydraulic ib leeg. Qhov ntsuas siab tshaj plaws yog 20 MPa. Nyob rau hauv qhov kev sim siab, lub sij hawm ruaj khov yuav tsum tsis pub tsawg tshaj 10 S, thiab cov yeeb nkab hlau yuav tsum tsis txhob tawm.
Tom qab tus neeg siv pom zoo, Kev Ntsuas Hydraulic tuaj yeem hloov pauv los ntawm Eddy Tam sim no Kev Ntsuas lossis Kev Ntsuas Flux Magnetic.
Flattening Test:
Tubes nrog ib txoj kab uas hla sab nraud loj dua 22 hli yuav tsum raug rau qhov kev ntsuam xyuas flattening. Tsis pom kev delamination, pob dawb, lossis impurities yuav tsum tshwm sim thaum tag nrho kev sim.
Flaring Test:
Raws li qhov yuav tsum tau muaj ntawm tus neeg yuav khoom thiab tau teev nyob rau hauv daim ntawv cog lus, cov yeeb nkab steel nrog txheej txheej ≤76mm thiab phab ntsa Thickness ≤8mm tuaj yeem ua tiav Flaring Test. Qhov kev sim tau ua nyob rau hauv chav kub nrog ib tug taper ntawm 60 °. Tom qab Flaring, Qhov Flaring Rate ntawm Sab Nrauv Sab Nraud Yuav Tsum Tau Ua Raws Li Cov Lus Qhia hauv qab no, thiab cov khoom siv kuaj yuav tsum tsis txhob muaj qhov tawg lossis tawg.
Hardness Test:
Brinell los yog Rockwell hardness tests yuav tsum tau ua ntawm cov qauv ntawm ob lub raj los ntawm txhua qhov ntau
