Saib xyuas cov hlaim hlwb ua kom sov

Cov ntaub qhib hnyav tsuag hluav taws xob yog cov khoom tshiab uas ua tiav los ntawm kev hnyav thiab ua haujlwm nrog cov ntaub qhib hluav taws xob. Vim nws tau ua tiav nrog ntau yam kev hnyav hluav taws xob, qhov chaw ntim ntawm nws zoo dua li cov ntaub qhib hluav taws xob. Tom qab ua haujlwm nrog kev ua haujlwm txog hluav taws xob, cov kev ua haujlwm hluav taws xob ntawm nws kuj zoo siab dua.

Rau txhua qhov txheej xwm sib txawv ntawm txhua lub tsev haujlwm, qhob ntoo ua los ntawm kev txiav sov feem ntau raug chia ua ob peb hom sib txawv. Qhob ntoo ua los ntawm kev txiav sov raug muab rau hauv qhob lossis qhob pliag, thiab nws qhob siab feem ntau raug piav qhia los ntawm millimeters. Rau qhov dav, lawv feem ntau muaj 1000mm thiab 1250mm qhob dav, thaum qhob rov dav feem ntau yog 2000mm thiab 2500mm. Cov qhob ntoo ua los ntawm kev txiav sov no tsis only muaj cov khoom siv zoo thiab qhob chaw nruab nrog qhov zoo, tab sis kuj tseem zoo nkauj rau kev tiv thaiv roj hmab, kev tiv thaiv kev yuav tsum paug thiab qhov zoo nkauj. Yog li ntawd, lawv raug siv dav hauv qhov chaw ua tiav, tsev, cov khoom siv hauv tsev, kev lag luam thiab lwm yam.

Ib hom qhob ntoo ua los ntawm kev txiav sov

Cov hom siv dav yog:

Q195, Q215, Q235, 08AL, SPCC, SPCD, SPCE, SPCEN, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC05, DC06 thiab lwm yam;

ST12: Piav qhia tias yog qhov zoo tshaj plaws, nrog Q195, SPCC, DC01 hom khoom sib npaug nrog qhov zoo tshaj plaws;

ST13/14: Sau tso rau hauv qab zog qhov chaw tsau ntoo, thiab 08AL, SPCD, DC03/04 qhov chaw khoom los yog tshuav zoo li ib yam;

ST15/16:Sau tso rau hauv qab zog qhov chaw tsau ntoo, thiab 08AL, SPCE, SPCEN, DC05/06 qhov chaw khoom los yog tshuav zoo li ib yam.

Japan JIS qhov chaw muaj ncauj lus li cas

SPCCT thiab SPCD txhais li cas?

SPCCT txhais tau hais tias yog cov ntoo hlaim hlai hlai uas muaj qhov loj ntawm kev hla siab tswv hwm hauv Japanese JIS standard, thaum SPCD txhais tau hais tias yog cov ntoo hlaim hlai hlai rau hauv qab zog hauv Japanese JIS standard, thiab qhov chaw ua liaj ua teb ntawm nws yog 08AL (13237) zoo siab hlaim hlai hlai.

Nyob rau hauv qab no, txog cov lej qhia ntawm qhob hlau carbon rov tav dav thiab kab, qhob hlau sov dav yog A, qhob hlau zoo tshwj xeeb yog S, 1/8 zoo sov yog 8, 1/4 zoo sov yog 4, 1/2 zoo sov yog 2, thiab zoo siab tshaj yog 1. Cov lej qhia ntawm qhov chaw ntim yog D rau qhov tsis zoo huv thiab B rau qhov zoo huv, piv txwv li SPCC-SD qhia txog qhob hlau carbon rov tav dav thiab kab siv tshwj xeeb nrog qhob hlau zoo tshwj xeeb thiab qhov chaw tsis zoo huv; SPCCT-SB qhia txog qhob hlau zoo tshwj xeeb, qhob hlau zoo huv rov tav dav hlau carbon sheet; thiab SPCCT-SB qhia txog qhob hlau zoo tshwj xeeb, qhob hlau zoo huv rov tav dav hlau carbon sheet rau siv tshwj xeeb nrog qhob hlau zoo tshwj xeeb thiab qhov chaw tsis zoo huv. Qhob hlau zoo tshwj xeeb, zoo processing, rov tav dav hlau carbon sheet yuav tsum paub txog cov kev ua haujlwm; SPCC-1D yog qhia tias yoo, tsis zoo huv qhob hlau rov tav dav hlau carbon sheet.

Lub ntsiab lus ntawm qhov loj ntawm kev ua haujlwm ua ntoo ua rau kev ua haujlwm yog qhia raws li no: S + kabon tom qis + lus npe (C, CK), qhov kabon tom qis muaj qhov kauv nrog * 100, lub C qhia kabon, lub K qhia tias lub ntoo ua rau kev ua haujlwm.

Lus qhia txog kev ua ntoo ua rau kev ua haujlwm ntawm lub chaw ua lag luam GB

Tshwj xeeb yog qhia raws li: Q195, Q215, Q235, Q255, Q275, thiab lwm yam. Q qhia tias qhov chaw ua haujlwm ntawm lub ntoo ua rau kev ua haujlwm "yield" thawj npe ntawm npe ntawv hanyu pinyin, 195, 215, thiab lwm yam qhia tias qhov chaw ua haujlwm ntawm qhov ntsiab lus ntawm kabon tom qis, kabon tom qis: Q195, Q215, Q235, Q255, Q275, qhov kabon tom qis loj dua, qhov manganese loj dua, qhov kev ua haujlwm zoo dua.
