Dab tsi yog Qib 5.6 Screw Spike
Lub railway ntsia hlau ntsia hlau yog ib qho tseem ceeb fastener nyob rau hauv railway khiav systems, feem ntau yog siv los tuav rails ruaj khov rau cov ntoo lossis pob zeb pw. Lub spike nta ib lub square lossis hexagonal lub taub hau tsim, ua kom yooj yim installation nrog cov cuab yeej tshwj xeeb thaum ua kom muaj kev ruaj ntseg thiab kev nyab xeeb. Qib tus naj npawb 5.6 txhais tau hais tias lub zog tensile yam tsawg kawg nkaus ntawm 500 MPa thiab qhov tsawg kawg nkaus yield zog ntawm 300 MPa, xam raws li 500 npaug ntawm 0.6. Qib no yog ib qho kev xaiv rau cov kab thib ob, sab hauv, thiab cov qauv thauj khoom uas yuav tsum tau muaj zog tuav.
Kev xaiv khoom
Qib 5.6 ntsia hlau spikes feem ntau yog tsim los ntawm nruab nrab carbon steel xws li 35 # steel, uas ncav cuag lub zog yuav tsum tau tom qab kub sib sau thiab kev kho cua sov. Tsawg carbon steel xws li Q235 feem ntau yog siv rau qib 4.6 fasteners, qhov twg qhov tensile yuav tsum yog 400 MPa. Rau qib 8.8 thiab siab dua, 45 # steel lossis hlau alloy yog siv. Kev xaiv cov khoom yuav tsum yeej ib txwm ua raws li lub zog ntawm chav kawm, vim hais tias qib guarantees yog raws li qhov tseeb txhua yam khoom ntawm cov khoom tiav.
Mechanical Properties
Rau qib 5.6, lub zog tensile tsawg kawg yog 500 MPa thiab lub zog tawm los yog tsawg kawg yog 300 MPa, nrog qhov tsawg kawg nkaus elongation ntawm 20 feem pua. Cov pob txha yuav tsum dhau qhov ntsuas 90℃txias khoov yam tsis muaj qhov tawg. Cov qib siab dua hauv tib tsev neeg cov khoom lag luam nce mus txog 800 MPa rau qib 8.8 thiab 1000 MPa rau qib 10.9, nrog rau kev sib raug zoo dua yield zog thiab qis elongation. Tag nrho cov khoom siv kho tshuab raug txheeb xyuas los ntawm kev sim cov qauv los ntawm txhua pawg tsim khoom.
Specification Txheej txheem cej luam
Feem ntau hom rau pob zeb pw fastening muaj xws li Ss5-150, Ss8-140, Ss8-150, Ss8-160, Ss23-160, Ss25-165, thiab Ss35-161 ntsia hlau spikes, ua ke nrog V20-135, V23-115-V, V2, V23-215, thiab V26-115 hom. Cov qauv siv yog ISO 898-1 rau cov khoom siv kho tshuab, UIC864-1 rau cov ntsia hlau pw tsaug zog, thiab NF F500-50 rau Fabkis txoj kev tsheb ciav hlau fasteners. Hom kev cai tuaj yeem tsim raws li cov neeg siv khoom kos duab.
Nto xaiv
Cov chaw muaj xws li cov roj av dawb, oxide dub, zinc plating, kub -dip galvanizing, wax, bitumen, Dacromet, thiab sherardizing. Plain oiled thiab dub tiav yog kev xaiv kev lag luam rau qhov chaw qhuav, thaum galvanizing thiab Dacromet tiv thaiv corrosion hauv cov av noo thiab ntug hiav txwv. Qhov saum npoo yog xaiv ua ke nrog cov qib zog kom phim cov kev pabcuam ntawm cov kab.
