Txheej txheem cej luam
Kev poob siab- cov hlau tsis muaj zog yog tsim los kom muaj kev cuam tshuam siab (tawv tawv), nrog rau lwm yam khoom xws li lub zog, hardness. Silicon yog ib qho kev sib ntxiv rau cov chav kawm ntawm cov hlau no, vim nws muab tempering tsis kam thiab ua rau muaj zog ntxiv.[1]
Cov ntawv thov rau kev poob siab-cov hlau tsis muaj zog suav nrog cov springs, nrog rau chisels, tuag rau forging, thiab xuas nrig ntaus.[1] S2 steel kuj yog siv los ua pob bearings rau kev lag luam mining.[2] Lawv kuj yog siv rau cov ntsia hlau ntsia hlau thiab cov khoom tsav tsheb.[3]

S2 alloy steel yog ib qho kev poob siab -cov cuab yeej steel hom. Nws khaws cia zoo ductility txawm nyob rau hauv hardened tej yam kev mob, uas tso cai rau nws mus ua nyob rau hauv daim ntawv thov qhov kev poob siab yuav kis tau mus rau lub alloy. Kev poob siab- tiv thaiv cov cuab yeej hlau zoo li no tau raug xaiv los ua pawg S steels.

FAQ
Q: Puas yog S2 tiag tiag tuav cov ntsia hlau ntsia hlau uas tau twisted nyuaj txhua hnub?
A: Yog - qhov ntawd yog qhov nws tau tsim rau. Lub 6.35mm hex loj yog cov qauv sib xws, thiab S2 khaws nws cov ductility txawm tias ntawm HRC 55-58, yog li cov lus qhia tsis snap tawm ntawm sab load. Peb muab cov kab puag ncig hauv av rau qhov loj hex ncaj qha - koj tsuas yog txiav thiab broach.
Q: Yuav ua li cas S2 piv rau S7 rau qhov txias-forming punch - kuv yuav xaiv qhov twg?
A: S7 muaj ntau cov chromium thiab molybdenum (3.0–3.5% Cr, 1.3–1.8% Mo) thiab hardness zoo dua ntawm hardness dua, tab sis S2 yog pheej yig dua thiab yooj yim rau tshuab hauv lub xeev annealed. Rau xuas nrig ntaus me me hlau mus txog 6 hli tuab, S2 ua haujlwm zoo. Rau cov khoom tuab lossis tawv, nce mus rau S7.
Q: Kuv pom lub zog tensile teev ntawm 2150MPa - puas yog tiag tiag, thiab kuv puas tuaj yeem siv S2 rau lub zog siab bolts?
A: Tus lej ntawd yog tiag tiag, tab sis nws yog rau cov tawv tawv thiab tempered mob. Txawm li cas los xij, cov cuab yeej hlau tsis yog rau cov fasteners - nws yog nkig ntawm lub zog ntawd. Siv nws rau cov cuab yeej, tsis yog cov qauv bolts. Peb muag nws rau cov neeg tsim khoom me me, tsis yog rau lub khw muag khoom.
Q: Kuv yuav kwv yees li cas qhov hnyav ntawm qhov ntev S2 bar rau tus nqi thauj khoom - koj puas muaj daim duab ntom ntom?
A: Peb siv 7.83 g / cc. Rau ib puag ncig bar, nws yog πr² × ntev × 7.83 ÷ 1000 kom tau kg ib meter. Rau cov Tshuag tiaj tus, nws yog dav × thickness × ntev × 7.83. Peb kuj tuaj yeem txiav rau koj qhov ntev npaum li cas thiab hnyav txhua pob khoom ntawm peb cov nplai hauv pem teb - koj them tus nqi tiag tiag.
Q: Koj puas tau yaj thiab tsim qhov no koj tus kheej, lossis koj tsuas yog tus tub luam?
A: Peb yog ib lub zeb ntiag tug - peb ua peb tus kheej smelting, refining, forging, machining, thiab kev kho cua sov. Qhov ntawd txhais tau tias peb tswj cov chemistry los ntawm cov yaj mus rau qhov kawg bar. Yog tias koj xav tau qhov loj me me lossis kev cai profile, peb tuaj yeem kho cov txheej txheem forging es tsis yog txiav los ntawm Tshuag.
Q: Koj lub tuam txhab nyob hauv Sichuan, tab sis cov lus piav qhia hais tias Hubei yog lub nroog ntawm cov cuab yeej hlau - koj puas xa nkoj los ntawm qhov twg?
A: Peb lub hauv paus tsim khoom yog nyob rau hauv Hubei - uas yog qhov chaw forging thiab cua sov-kho kab. Sichuan chaw ua hauj lwm tswj kev muag khoom thiab export. Tag nrho cov khoom xa tuaj tawm ntawm peb lub tsev khaws khoom hauv Hubei, ze rau cov chaw nres nkoj loj. Lub sijhawm coj mus rau Shanghai yog li 3 hnub los ntawm lub tsheb thauj khoom, tom qab ntawd mus rau cov nkoj ntim khoom.
