Dab tsi yog threaded steel thauj tog rau nkoj pas nrig siv hauv mining

Kev ua tau zoo ntawm mining threaded steel thauj tog rau nkoj rods tau mus txog thoob ntiaj teb qib siab, nrog cov qauv tsim nyog
Tag nrho cov xov ntev ntawm lub thauj tog rau nkoj pas nrig muaj sib npaug zog, uas ua rau kom cov kabmob muaj peev xwm los ntawm 40% piv rau tib cov ntsiab lus thauj tog rau nkoj pas nrig;
Kev nthuav dav ntawm cov khoom siv thauj tog rau nkoj, nws tuaj yeem ua tiav thauj tog rau nkoj, txuas ntxiv thauj tog rau nkoj, thiab thauj tog rau nkoj tag nrho; Yooj yim rau kev khiav lag luam,
Nws muaj qhov zoo ntawm tus nqi qis thiab yog siv dav rau kev txhawb nqa ntau hom tunnels hauv thee mines, railways, hydropower thiab lwm yam haujlwm engineering.
Threaded steel thauj tog rau nkoj pas nrig siv hauv kev tsuas yog siv los txhawb cov pob zeb nyob ib puag ncig ntawm kuv qhov tunnels thiab underground engineering, uas tuaj yeem ua kom muaj kev ruaj ntseg ntawm cov pob zeb ib puag ncig ntawm mine tunnels thiab underground engineering. Nws cov yam ntxwv nta: tag nrho qhov ntev ntawm tus pas nrig lub cev muaj cov xov txuas txuas ntxiv, nrog lub zog sib npaug thoob plaws tag nrho ntev; Lub fastening kawg yog nruab nrog ib tug pre-stressed gasket thiab ib lub pob nut. Nws yog superior rau thauj tog rau nkoj rods txheej txheem nrog puag ncig steel, nrog rau cov nram qab no zoo: 1. Lub anchoring thiab fastening xaus tsis yuav tsum tau machining; 2. Tag nrho ntev sib npaug zog, siab siv cov khoom siv; 3. Siab anchoring quab yuam; 4. Nruab nrog pre-stressed gaskets, yooj yim los tswj installation zoo; 5. Kev txhim kho ceev ceev, thiab lwm yam. Nws yog ib yam tshiab ntawm cov khoom thauj tog rau nkoj nrog cov khoom txuag, kev txuag hluav taws xob, thiab muaj zog sib npaug, thiab muaj kev cia siab dav rau kev nce qib thiab daim ntawv thov.
Peb lub Hoobkas tsuas yog tsim cov khoom hauv qab no: 16 # mining threaded steel thauj tog rau nkoj pas nrig, 18 # mining threaded steel thauj tog rau nkoj pas nrig, 20 # mining threaded steel thauj tog rau nkoj pas nrig, thiab 22 # mining threaded steel thauj tog rau nkoj pas nrig
