Ubulukhuni obuphezulu be-Tungsten Carbide Roller Ring ye-Speed ​​​​Speed ​​​​Rolling ye-Alloy Steel Bars

Amakhonkco e-Carbide roller azalwa kunye nophuhliso loshishino lwesinyithi emva kokufika kobuchwepheshe besinyithi somgubo ngo-1909. ngenxa yeenjongo ngeendawo, kubonakale omnye emva komnye.Nangona kunjalo, ukusetyenziswa okukhulu kweerola ze-carbide ze-cemented kwafika emva kwe-1960. Ngo-1964, ukuzalwa kwesixhobo sokuqala esinesantya esiphezulu se-twist-free rod rod rod ye-Morgen Company kwandisa isantya sokugqiba i-wire rod ngamaxesha angama-4.Ekubeni iyunithi yokugqiba i-rolling mill isebenza ngesantya esiphezulu kunye noxinzelelo oluphezulu, ii-roller zentsimbi kunye nezixhobo zentsimbi zinamandla okumelana nokunxiba, ubomi be-groove bufutshane, kunye nokulungiswa kunye nokulayishwa kunye nokukhulula imiqulu rhoqo kakhulu, nto leyo echaphazelayo. ukusebenza kakuhle kwelitye lokusila kwaye akusafaneleki ukugqiba imveliso yokuqengqeleka.iimfuno, ngoko ke yatshintshwa iirola ezidityanisiweyo carbide.Kukho ngaphezu kwama-200 eengcambu zokusila ehlabathini, ezitya amakhulu eetoni zesamente eqengqelekayo ye-carbide minyaka le.
