Ua kom cov billets sov hauv lub cub tawg mus rau qhov kub dov.
KUB-ROV: Cov hlau billet raug kub-dov rau hauv ib txoj hlua zoo (25 kg / m txog 60 kg / m) los ntawm lub tshuab dov.
3. Txias thiab Ncaj
Kev tswj cua txias rau qhov nyuaj thiab tawv.
Txhuam cov hlau kom raug qhov loj me, ncaj cov hlau raws li qhov tsim nyog.
4. Txiav & Ua tiav
Txiav cov hlau kom loj (12-25 m yog qhov ib txwm muaj).
Ua tiav lub taub hau tsheb ciav hlau, ko taw thiab lub ntsej muag web
5. Kev Tshuaj Xyuas Zoo
Sim cov khoom siv kho tshuab (yield, tensile, hardness) ntawm hlau.
Ntsuas qhov loj thiab qhov zoo ntawm qhov chaw.
Ua NDT yog tias xav tau.
6. Kev Npaj Ntim Khoom & Kev Xa Khoom
Khi cov hlau nrog cov pob khoom, ntxiv cov hau kawg tiv thaiv.
Npog nrog cov ntaub qhwv dej tsis pub dej nkag rau kev xa tawm xwb.
Thauj khoom rau kev xa khoom lossis kev xa khoom "
Kev tsim kho txoj kev tsheb ciav hlau rau cov tsheb ciav hlau thauj khoom thiab cov neeg caij tsheb
Kev tsheb ciav hlau rau kev lag luam hauv kev tsuas, chaw nres nkoj, thiab chaw khaws khoom
Cov hlau thauj khoom hnyav rau kev thauj khoom hauv cov chaw logistics thiab cov chaw lag luam
Kev kho dua tshiab thiab kev saib xyuas ntawm cov kev tsheb ciav hlau uas twb muaj lawm

Kev thauj mus los ntev thiab kev thauj khoom hauv hiav txwv nrog cov ntaub qhwv dej tsis nkag
Cov hau yas lossis hlau ntawm qhov kawg kom tiv thaiv kev puas tsuaj thaum thauj khoom / tshem tawm
Chaw nres nkoj ntawm keeb kwm mus rau tus neeg yuav khoom qhov chaw xa khoom muaj nrog kev taug qab
MTC puv ntoob rau txhua qhov kev xa khoom
1. Cov hlau EN R260 thiab R350HT yog dab tsi?
Lawv yog cov qib zoo hlau uas tau muab faib ua pawg raws li cov qauv tsheb ciav hlau European. R260 raug pom zoo rau cov neeg caij tsheb thiab cov tsheb thauj khoom txheem, thaum R350HT yog txoj kev tsheb ciav hlau muaj zog siab uas haum rau cov ntawv thov hnyav. Ob leeg ua raws li tus qauv EN 13674.
2. Cov cheeb tsam tseem ceeb ntawm daim ntawv thov yog dab tsi?
Kev Tsheb Ciav Hlau(neeg caij tsheb thiab khoom thauj), txoj kev tsheb ciav hlau hauv cov chaw tsuas, chaw nres nkoj, thiab cov chaw tsim khoom; txoj kev tsheb ciav hlau thauj khoom hnyav rau kev xa khoom thiab chaw ua lag luam; kev saib xyuas thiab hloov cov txoj kev tsheb ciav hlau uas tau teeb tsa lawm.
3. Yuav ua li cas thiaj txiav txim tau thiab xa tawm?
Kev xa tawm ntawm tsheb ciav hlau yuav tsum muaj daim ntawv pov thawj MTC, thiab cov khoom ntim yuav tsum ua raws li cov qauv thoob ntiaj teb (cov khoom ntim khoom, cov khoom ntim dej tsis nkag, lub hau kawg). Lub sijhawm ua cov qauv yog 7-14 hnub, thiab lub sijhawm ua ntau yog 3-6 lub lis piam. Thov hu rau peb pab neeg muag khoom kom tau txais tus nqi.
