Chidule chachidule cha ndodo yowotcherera ya Q690 yachitsulo

2.Kuyambitsa mwachidule kwa mbale yachitsulo ya Q690

Mayiko Gawo lachitsulo la Q690	Q690A	Q690B	Q690C	Q690D	Q690E	Q690F
Nthenga	Hot adagulung'undisa		Kuzimitsa + kupsya mtima (zozimitsidwa ndi kupsya mtima)
Zonyansa	Okwera P/S		otsika P/S		Zochepa P/S
Zofunika Zowopsa	NO	Kutentha kwachibadwa	0 ℃	-20 ℃	-40 ℃	-60 ℃

Komabe, pakadali pano, mbale yachitsulo ya 690MPa ya zombo zoponderezedwa zapakhomo imachokera ku European standard EN10028-6, ndipo zofunikira zalembedwa mwachidule patebulo ili:

Perekani zitsulo 690MPA pazida zokakamiza za ku Europe	P690Q	P690QH	P69QL1	P69QL2
Nthenga	mbewu yabwino kuzimitsidwa ndi tempered chitsulo
zofunika mphamvu	Zokolola≥690MPa(mbale makulidwe≤50mm) Tensile770-940MPa
Zonyansa	P≤0.025%,S≤0.015%		P≤0.02%,S≤0.010%
Zofunika Zowopsa	20 ≥60J	20 ≥60J	0℃≥60J	-20 ≥40J
	0℃≥40J	0℃≥40J	-20 ≥40J	-40 ≥27J
	-20 ≥27J	-20 ≥27J	-40 ≥27J	-60 ≥27J
Magawo akuluakulu ofunsira	Zomangamanga zonyamula kukakamiza kapena zotengera zopanikizika zomwe zimakhala ndi mphamvu zochepa zolimba		Tanki yozungulira yokhala ndi zofunikira zapamwamba zaukadaulo	Liquefied gas marine liquid tank

Monga mbale yachitsulo yosungiramo akasinja ndi mphamvu ya kupanikizika, iyenera kukhala ndi mphamvu zabwino ndi kulimba, kuzizira kopinda komanso kutsika kwa ming'alu.Ngakhale chitsulo chozimitsidwa ndi chotenthedwa cha Q690 chili ndi mpweya wocheperako komanso wokwanira bwino kwambiri, chimakhalabe ndi chizolowezi chowumitsa poyerekeza ndi zitsulo zina za 50/60kg, ndipo chithandizo cha kutentha pambuyo pa weld chimafunika.Komabe, kafukufuku wambiri woyesera awonetsa kuti pazitsulo zowotcherera zitsulo za Q690, kulimba kwamphamvu kwapang'onopang'ono kudzawonongeka kwambiri pambuyo pa chithandizo cha kutentha kwa nkhawa, komanso pakuwonjezeka kwa kutentha kwa kutentha ndi kuchepa kwa kutentha kwamphamvu, kuwonongeka. za kuwotcherera consumable kulimba adzakhala zoonekeratu.Choncho, ndizofunika kwambiri kuti mukhale ndi mphamvu zowonjezera, zogwira mtima kwambiri, ndi ndodo zowotcherera kutentha kwa Q690 zitsulo kuti zigwiritse ntchito bwino zitsulo za Q690 ku zipangizo zogwiritsira ntchito mphamvu, kuchepetsa zipangizo zachitsulo, ndi kuchepetsa ndalama zopangira.

4.Q690 zitsulo kuwotcherera ndodo makina ntchito chionetsero

Onetsani:
1. "X" yolembedwa ndi zilembo zofiira mu American Standard ndi European Standard imayimira mtundu wa khungu lamankhwala.
2. GEL-758 imagwirizana ndi E11018-G ndi ISO 18275-B E7618-G A mu AWS ndi ISO miyezo motsatira.
3. GEL-756 imagwirizana ndi E11016-G ndi ISO 18275-B E7616-G A mu AWS ndi miyezo ya ISO motsatira.
Makina amakina a Q690 zitsulo zowotcherera ndodo mu boma la kutentha

Onetsani:

1. Miyezo yokhudzana ndi AWS ndi ISO ilibe zofunikira pakuwongolera kutentha kwazinthu zomwe zili pamwambapa.Zochizira za kutentha zomwe zili pamwambazi zikufotokozedwa mwachidule malinga ndi luso la makasitomala ambiri ndipo ndizomwe zimangogwiritsidwa ntchito.
2. GEL-118M imakhala ndi mphamvu zolimba kwambiri pa -40 ° C pambuyo pa chithandizo cha kutentha, ndipo kuwonongeka kwa mphamvu pa -50 ° C kumaonekera kwambiri.
3. Pambuyo pa chithandizo cha kutentha, GEL-758 imakhala ndi mphamvu zolimba kwambiri pa -40 ° C, kulimba kwabwino kwa -50 ° C, ndi kuwonongeka koonekera pa kutentha kwa -60 ° C.
4. Kutentha kwapang'onopang'ono kwamphamvu kwa GEL-756 pambuyo pa chithandizo cha kutentha kumakhala kochepa, ndipo kutentha kwapakati pa -60 ° C kumakhala bwino.

Q690 zitsulo kuwotcherera ndodo zodzitetezera

1. Kusungirako zinthu zowotcherera:
Kuwotcherera consumables tikulimbikitsidwa kusungidwa nthawi zonse kutentha ndi youma mikhalidwe, ndi kuikidwa pa pallets kapena maalumali, kupewa kukhudzana mwachindunji ndi makoma ndi pansi.

2. Kukonzekera musanayambe kuwotcherera:
Chotsani bwino chinyezi, dzimbiri, madontho amafuta, ndi zina zambiri pamwamba pa zinthu zapansi, ndipo pewani chinyezi chapansi kapena mvula ndi matalala.

3. Njira zoteteza mphepo:
Pamene kuwotcherera, ziyenera kuwonetseredwa kuti pazipita mphepo liwiro malo kuwotcherera si upambana 2m/s.Apo ayi, njira zotetezera ziyenera kuchitidwa.

4. Kutenthetsa:
Ndikoyenera kugwiritsa ntchito zida zotenthetsera zamagetsi kuti zitenthetse chogwirira ntchito kupitilira 150 ° C musanayambe kuwotcherera.Ngakhale musanayambe kuwotcherera, iyenera kutenthedwa mpaka 150 ° C.

5. Kuwongolera kutentha kwa msewu:
Panthawi yonse yowotcherera, kutentha kwa interpass sikuyenera kutsika kuposa kutentha kwa preheating, ndipo kutentha kovomerezeka ndi 150-220 ° C.

6. Kuchotsa haidrojeni pambuyo kuwotcherera:
Pambuyo kuwotcherera msoko, nthawi yomweyo onjezerani kutentha kwa magetsi mpaka 250 ℃ ~ 300 ℃, sungani kutentha kwa maola awiri mpaka 4, kenako muzizizira pang'onopang'ono.
① Ngati makulidwe a workpiece ndi ≥50mm, nthawi yogwira iyenera kupitilira maola 4-6, kenako itakhazikika pang'onopang'ono.
② Pansi pa makulidwe akulu ndi kuletsa kwakukulu, dehydrogenation ina imatha kuwonjezedwa pambuyo pakuwotcherera ku 1/2 makulidwe, ndikukhazikika pang'onopang'ono mpaka kutentha kwa interpass.

7. Kapangidwe kapansi:
Ndibwino kuti mugwiritse ntchito kuwotcherera kwamitundu yambiri ndi ma pass-pass, ndipo liwiro la kuwotcherera liyenera kusungidwa pafupipafupi.
