UHP graphite electrode feem ntau yog siv rau lub zog hluav taws xob hluav taws xob hluav taws xob hluav taws xob uas muaj qhov ceev tam sim no ntau dua 25 A / cm2.
Khoom Paub meej
KHOOM Kev piav qhia
UHP graphite electrode yog siv rau kev rov ua dua ntawm cov hlau hauv kev lag luam hluav taws xob arc rauv. Nws cov khoom tseem ceeb yog koob coke uas muaj txiaj ntsig zoo uas yog tsim los ntawm cov roj av lossis cov thee tar. Graphite electrodes yog tiav nrog lub tog raj kheej zoo thiab machined nrog threaded cheeb tsam ntawm txhua kawg. Nyob rau hauv txoj kev no, cov graphite electrodes tuaj yeem sib sau ua ke rau hauv kab hluav taws xob siv cov txiv mis electrode.
Txhawm rau kom ua tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm siab dua thiab txo tus nqi tag nrho, lub peev xwm loj ultra-siab zog arc rauv tau ua ntau thiab nrov. Vim li no, UHP graphite electrodes nrog diameters tshaj 500 hli yuav ua lag luam.
KHOOM Feature
● Tiv thaiv cov dej ntws loj, tus nqi tso tawm siab.
● Zoo dimension stability, tsis yooj yim rau deform.
● Resistant rau tawg & spalling.
● Siab tiv thaiv oxidation thiab thermal shock.
● Lub zog txhua yam muaj zog, tsis tshua muaj hluav taws xob tsis kam.
● High machining raug, zoo nto tiav.
KHOOM Daim ntawv thov

Yam khoom
Nyob rau hauv 1985, Datong Locomotive Works pom tau hais tias hluav taws xob locomotives yog qhov tseem ceeb txoj kev loj hlob ntawm Tuam Tshoj railway locomotive thiab dov Tshuag lag luam nyob rau hauv lub neej yav tom ntej, thiab muab tso rau pem hauv ntej lub tswv yim tsim khoom ntawm "Nanzhu (Zhuzhou Electric Locomotive Works) thiab Datong Locomotive Works".
Shaoshan Hom 3 hluav taws xob locomotive yog kuv lub teb chaws thib ob tiam 6-axle neeg nrog caij thiab tsheb thauj mus los. Lub locomotive txais tus choj-hom tag nrho-yoj rectification thiab paub txog thyristor theem-tswj tus voltage tswj. Lub locomotive txais ib-theem AC 25kV 50Hz voltage system thiab muaj kev khiav hauj lwm siab tshaj plaws ntawm 100km / h.
Lub SS3B tsau hnyav hluav taws xob locomotive yog 12-axle freight electric locomotive. Nws muaj ob qhov zoo tib yam 6-qag locomotives txuas los ntawm ib lub coupler thiab ib lub tshuab cua. Ob ntu yog nruab nrog cov khoom siv hluav taws xob high-voltage connectors, tswj cables, thiab kev tiv thaiv network. Kab thiab cua system tswj ducts. Tag nrho lub tsheb tuaj yeem tswj tau synchronously ntawm txhua lub cab. Lub locomotive txais ib-theem fais fab zaus system, voltage 25kV, AC-DC kis tau tus mob, thiab lub siab tshaj plaws kev khiav hauj lwm ceev ntawm lub locomotive yog 100km / h.
Shaoshan 4 txhim kho hluav taws xob locomotive yog 8-axle freight locomotive. Lub locomotive muaj ob zoo tib yam plaub-axle locomotives txuas nrog ib tug coupler thiab ib tug windshield. Ob lub rooj cob qhia yog nruab nrog high-voltage connectors rau cov hluav taws xob system, reconnection tswj cables thiab cua nres system tswj ducts. Tag nrho lub tsheb tuaj yeem synchronously tswj los ntawm tus tsav tsheb cab ntawm ib qho ntawm lub tsheb. Ob lub locomotives tseem tuaj yeem sib cais thiab siv nws tus kheej ua plaub-qag locomotive.
