1.Vim li cas txias -rolled coils haum rau ua gaskets?
High precision thiab zoo nto tiav: Txias -rolled coils muaj ib tug du thiab tiaj tus nrog nruj thickness kam rau ua. Qhov no ua rau muaj qhov ruaj khov stamped gaskets nrog tsawg burrs, tso cai rau siv ncaj qha yam tsis muaj kev siv tshuab ntxiv.
Lub zog nruab nrab thiab ruaj khov: Piv rau cov ntawv kub- dov, txias- dov coils muaj hardness ntau dua (ib lub zog compressive) thiab tsawg dua springback thaum lub sij hawm stamping, ua kom yooj yim los tswj lawv cov duab.
Tus nqi qis thiab kev ua haujlwm siab: Zoo tagnrho rau kev siab - nrawm stamping thiab ntau lawm, muab cov khoom siv siab thiab kev ua haujlwm siab heev.
2.Dab tsi yog qhov yuav tsum tau ua rau txias- dov coils siv hauv cov tshuab dav dav, hluav taws xob, thiab kev tsim kho gaskets?
Suitability: Zoo heev.
Cov qib pom zoo: Q235 (cov pa roj carbon zoo ib yam steel txias- cov ntawv dov, xws li SPCC) lossis 08F (siab- zoo carbon structural steel txias-rolled sheet).
Lus Cim: Rau feem ntau cov gaskets zoo tib yam uas tsis xav tau lub zog siab thiab tsuas yog yuav tsum tau ntim cov khoob lossis tiv thaiv kom tsis txhob xoob, qhov txias txias -rolled sheet yog qhov kev xaiv pheej yig tshaj plaws.
3.Dab tsi yog qhov yuav tsum tau rau lub gasket nrog ib tug tej yam kev mob ntawm elasticity los yog hardness?
Applicability: Tsim nyog (yuav tsum tau kho cua sov).
Cov Qib Pom Zoo: 65Mn (txias-rolled caij nplooj ntoos hlav steel sawb) los yog 60Si2Mn.
Lus Cim: Yog tias koj tab tom ua cov tshuab ntxhua khaub ncaws, lub eeb ntxhua khaub ncaws, lossis cov ntxhua khaub ncaws tiaj tus uas yuav tsum tau ua kom muaj zog ntxiv, siv cov khaub thuas zoo tib yam -rolled steel sheet (Q235) yog mos heev thiab yooj yim deformation. Nyob rau hauv rooj plaub no, koj yuav tsum siv txias- dov lub caij nplooj ntoos hlav steel sawb (xws li 65Mn), uas yuav tsum tau stamped thiab ces quenched thiab tempered (kub kho) kom ua tau siab elasticity thiab hardness.
4.Puas txias-rolled coils haum rau siab -precision, nyias gaskets?
Suitability: Zoo heev.
• Qib pom zoo: High-zoo carbon steel txias-rolled strip.
• Ceeb toom: Txias-rolled coils muaj nyob rau hauv tsis tshua muaj nyias strips ntawm 0.1mm, 0.2mm, thiab 0.3mm, nrog nruj heev tuab tolerances (xws li PT.A los yog PT.B qib hauv GB/T 708), ua rau lawv zoo tagnrho rau precision kho shims.
5.Dab tsi zoo tib yam txias- dov coils siv rau hauv qhov chaw tshwj xeeb (kub kub, corrosion)?
Tsis haum rau cov khaub thuas zoo tib yam -rolled coils: Ordinary txias-rolled steel yog nquag xeb thaum raug dej los yog ya raws.
Lwm txoj kev:
Kev tiv thaiv xeb / kho kom zoo nkauj: Siv stainless hlau txias- cov coils (xws li SUS304, SUS316) lossis kev kho deg (galvanizing, blackening).
Rwb thaiv tsev / vibration damping: Nyob rau hauv rooj plaub no, tsis yog- cov khoom siv hlau (xws li liab hlau ntawv, roj hmab, PTFE, nylon) yuav tsum tau xaiv los ntawm steel txias- dov coils.
Kub kub: Thaum tshav kub kub-resistant steel los yog tshav kub-resistant alloys yuav tsum tau xaiv.
