Japanese standard channel steel yog ib tug ntev sawb ntawm steel nrog ib tug groove-shaped cross-section. Nws yog cov khoom siv carbon steel siv hauv kev tsim kho thiab tshuab. Nws yog cov khoom siv hlau profiled nrog cov ntu ntu ntu thiab muaj qhov zawj-shaped cross-section. American txuj channel steel yog tsuas yog siv nyob rau hauv lub tsev qauv, ntaub thaiv phab ntsa engineering, mechanical khoom thiab tsheb manufacturing, thiab lwm yam.
Cov ntaub ntawv ntawm Japanese standard channel steel yog: Q235B, A36, SS400, S490, S490A, S490B, thiab lwm yam.
Kev xa khoom ntawm Japanese tus qauv channel steel: Tshwj tsis yog tias tau teev tseg, nws raug xa hauv lub xeev kub dov lossis forging; Thaum siv los ua cov hlau tuag, nws feem ntau yog xa mus rau hauv lub xeev kub dov, normalizing, normalizing thiab tempering.
1) Normalizing Japanese standard channel steel: Cov txheej txheem kev kho cua sov uas cov hlau los yog cov hlau yog rhuab mus rau qhov kub uas tsim nyog tshaj qhov tseem ceeb ntawm AC3 lossis ACM, khaws cia rau qee lub sijhawm, thiab tom qab ntawd txias hauv huab cua kom tau txais ib qho pearlite zoo li qauv.
2) Annealing ntawm Japanese standard channel steel: ua kom sov lub hypoeutectoid steel workpiece rau 20-40 degrees saum AC3, cia nws sov rau ib lub sij hawm, thiab ces txias maj mam nrog rau lub cub tawg (los yog faus rau hauv xuab zeb los yog txiv qaub) rau Hauv qab 500 degrees hauv huab cua Nruab nrab cua txias cua sov txheej txheem.
Cov yam ntxwv ntawm Japanese tus qauv channel steel txheej txheem kev kho cua sov: Hlau kho cua sov yog ib qho ntawm cov txheej txheem tseem ceeb hauv kev tsim khoom. Piv nrog rau lwm cov txheej txheem ua, kev kho cua sov ntawm American standard channel steel feem ntau tsis hloov cov duab thiab tag nrho cov tshuaj muaj pes tsawg leeg ntawm lub workpiece, tab sis hloov cov microstructure nyob rau hauv lub workpiece, los yog hloov cov tshuaj muaj pes tsawg leeg ntawm lub workpiece nto endows los yog txhim kho cov kev ua tau zoo. ntawm lub workpiece. Nws yog tus cwj pwm los ntawm kev txhim kho qhov zoo ntawm lub workpiece, uas feem ntau tsis pom ntawm qhov muag liab qab. Txhawm rau ua kom cov hlau ua haujlwm muaj cov khoom siv kho tshuab, lub cev thiab cov khoom siv tshuaj lom neeg, ntxiv rau kev xaiv cov khoom tsim nyog thiab ntau yam txheej txheem, cov txheej txheem kho cua sov feem ntau yog qhov tseem ceeb. Hlau yog cov khoom siv dav tshaj plaws hauv kev lag luam machinery. Lub microstructure ntawm steel yog complex thiab tuaj yeem tswj tau los ntawm kev kho cua sov. Yog li ntawd, kev kho cua sov ntawm American standard channel steel yog cov ntsiab lus tseem ceeb ntawm kev kho cua sov hlau. Tsis tas li ntawd, txhuas, tooj liab, magnesium, titanium, thiab lwm yam thiab lawv cov alloys kuj tuaj yeem hloov lawv cov khoom siv kho tshuab, lub cev thiab tshuaj lom neeg los ntawm kev kho cua sov kom tau txais cov khoom sib txawv.
