Graphite crucible rau lithium roj teeb anode cov ntaub ntawv yog lub thawv zoo tagnrho siv nyob rau hauv cov txheej txheem graphitization ntawm carbon-based lithium roj teeb anode cov ntaub ntawv. Nws muaj cov yam ntxwv ntawm qhov kub thiab txias thiab tsis muaj impurities, thiab feem ntau tuaj yeem rov qab siv 3 mus rau 4 zaug.

Graphite crucible thiab nws lub hau yog tsim los ntawm kev siv graphitized petroleum coke thiab graphite hmoov raws li aggregates thiab thee pitch li binder, los ntawm cov txheej txheem xws li kneading, nias, roasting thiab mechanical processing. Txoj kev khiav yog raws li nram no:
1) Ntxiv graphite hmoov rau cov khoom siv raw ntawm graphitized petroleum coke hais. Cov mis muaj plaub yam hais, xws li 5 ~ 2mm, 2 ~ 1mm, 1 ~ 0mm, thiab tsawg dua 0.075mm.
2) Ntxiv cov khoom nyoos npaj rau hauv lub lauj kaub sib tov thiab do, tom qab ntawd ntxiv cov kua asphalt rau hauv lub lauj kaub sib tov, thiab txuas ntxiv stirring kom cov asphalt infiltrate cov roj av coke; tus nqi ntawm cov kua asphalt ntxiv, nyob rau hauv cov nqe lus ntawm huab hwm coj feem pua, yuav yog tag nrho cov npaj calcined petroleum coke. 25% mus rau 28% ntawm granular raw khoom thiab excipients.
3) Muab cov kneaded thiab txias muab tshuaj txhuam rau hauv lub tshuab ua kom siab (moulding tshuab) rau molding; lub extrusion siab yog 18-19MPa, thiab lub ntim ceev ntawm lub molded crucible ntsuab lub cev mus txog ntau tshaj 1.68g / cm3.
4) Muab lub crucible ntsuab lub cev rau hauv lub cub tawg tshwj xeeb uas tsim los rau kev kho cua sov kub ntawm 1300 ° C kom carbonize thee pitch nyob rau hauv lub cev ntsuab kom tsim tau cov neeg kho tshuab siab zog, qis zog, zoo thermal stability thiab chemical zog. Stable roasted khoom crucible. Thaum thauj lub cub tawg, sau nws nrog cov ntaub ntawv pabcuam kom ntseeg tau tias cov ntoo ntsuab tsis deform thaum lub sijhawm ci. Cov cua kub nkhaus ntawm roasting tuaj yeem yog 566h nkhaus. Lub voj voog roasting ntau lawm yog kwv yees li 22-30 hnub ntev dua, thiab tus nqi roasting tuaj yeem ncav cuag 92%.
5) Txiav cov roasted khoom crucible kom ua tau raws li qhov yuav tsum tau muaj qhov loj me, cov duab, precision, thiab lwm yam, thiab ua rau nws ua tiav cov khoom uas ua tau raws li qhov yuav tsum tau siv.

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.
