Kev siv thiab ua tiav cov teebmeem ntawm S330 Steel Txhaj Tshuaj
S330 yog qhov nruab nrab-loj-loj kheej kheej kheej kheej cam khwb cia hlau txhaj tshuaj raws li SAE J444 cov qauv nrog lub nominal txoj kab uas hla ntawm 1.0 hli. Nws cov hardness feem ntau yog los ntawm 40-55 HRC thiab qhov tseeb ceev nce mus txog 7.4 g / cm³. Ua tsaug rau qhov cuam tshuam loj zog,S330 steel txhajyog qhov zoo tagnrho rau kev ua haujlwm hnyav blasting uas yuav tsum tau ua kom zoo roughness yam tsis muaj kev puas tsuaj rau lub hauv paus hlau.
1. Cov ntawv thov kev lag luam tseem ceeb
(1) Structural-steel kev lag luam (Primary use)
Nws yog siv rau tuab H-beams, hnyav-lub luag hauj lwm steel daim hlau, choj Cheebtsam, PEB lub tsev thav duab thiab loj-loj welded sib dhos. S330 zoo tshem tawm cov tuab xeb txheej, zeb nplai thiab vuam slag. Nws pab ua tiav qib Sa2.5 lossis Sa3 kev huv huv uas xav tau rau kev pleev xim epoxy tom ntej thiab kub-dip galvanizing.
(2) Shipbuilding & offshore-kev lag luam
Ship hull seem, loj-loj marine castings thiab offshore platform cov qauv siv S330. Nws tshem cov xim muaj hnub nyoog, hiav txwv ntsev corrosion thiab sib sib zog nqus oxidation thaum lub nkoj kho thiab cov nkoj tshiab.
(3) Heavy-duty foundry thiab siv tshuab
Excavator thav duab, tsheb laij teb Cheebtsam, gear-box vaj tse thiab loj-scale cam khwb cia hlau workpieces yog zoo haum rau S330 blasting. Nws cleans adhered foundry xuab zeb thiab casting scale sai.
(4) Railway thiab pipeline tej yaam num
Tsheb ciav hlau bogies, wagon thav duab thiab tuab-wall steel pipelines siv S330 rau kev kho ua ntej ua ntej los tiv thaiv corrosion.
(5) Tua-peening rau qhov hnyav-load
Thaum xaiv50-55 HRC high-hardness qib S330, nws tuaj yeem tsim cov txheej txheem compressive-kev ntxhov siab ntawm cov springs thiab heavy-duty forging pieces, txhim kho qaug zog-ua hauj lwm zoo.
2. Nto-Tshuaj ntsuam xyuas ntawm S330 Steel Txhaj Tshuaj
Tswj roughness ntau yam: 40-75 μm. Qhov roughness no muab cov kev sib raug zoo zoo rau cov xim hnyav hnyav; piv nrog finer-size steel tua xws li S170 thiab S230, S330 tau txais ntau dua Ra tus nqi.
Uniform matte tiav: Spherical particles yuav tsis tsim tob txiav pits ntawm tuab-wall steel. Nws tsuas yog tshem tawm cov kab mob thiab ua kom lub hauv paus-hlau kev ntseeg ruaj khov. Thin-wall workpieces tsis pom zoo rau S330.
Kev ua haujlwm siab blasting: Raws li qhov loj me me, S330 ua tiav cov xeb tshem tawm sai dua li cov hlau me me thiab txhim kho kev ua haujlwm tag nrho.
Lub neej ntev rov ua dua: Peb cov qib zoo tshaj plaws S330 steel txhaj tshuaj tswj xyuas qhov zoo sib xws thiab qis hollow-particle tus nqi, uas tuaj yeem rov qab siv ntau pua zaus hauv cov tshuab tua hluav taws xob kaw.
3. Kev Xaiv Siv Tau
Xaiv S230: Rau nyias-phaj Cheebtsam thiab thaum tsawg-roughness xav tau.
Xaiv S330: Txuj kev xaiv rau tuab-wall structural-steel thiab hnyav-lub luag haujlwm cast-parts.
Xaiv S460-S660: Rau cov xeb tuab heev thiab ua haujlwm hnyav hnyav.
Hais txog peb cov khoom
Raws li cov chaw tsim khoom hauv Suav teb, peb tsim SAE-raws li S330 steel txhaj tshuaj nrog nruj tswj nruj thiab ceev. Peb muab cov hardness tsis tu ncua (40-55 HRC) thiab high-hardness versions (50-55 HRC) raws li cov neeg siv khoom xav tau tiag tiag blasting. Xav tias dawb hu rau peb pab neeg rau cov qauv thiab Hoobkas ncaj qha nqi.
