Úsáidtear imthacaí sorcóir barrchaolaithe ceithre shraith go forleathan le haghaidh muilte rollta éagsúla. Sin toisc gur féidir leo araon ualaí a sheasamh ó 2 threo. Tá Tedin gairmiúil i ndearadh agus déantúsaíocht imthacaí sorcóir barrchaolaithe mórmhéide do thionscail throma.
Buntáistí Tedin:
1. Ábhar Ard-íonachta:
Ábhar tré-chruaite: cruach DAYE nó cruach BAOSHAN GCr15SiMn, GCr18Mo, 100CrMo7-4, nó cruach OVAKO allmhairithe;
Ábhar cás-chruaite: cruach DAYE nó cruach BAOSHAN G20Cr2Ni4A, nó cruach OVAKO allmhairithe agus cruach TIMKEN;
2. Ard-chruinneas:
I gcás imthacaí muineál rolla le haghaidh muilte rollta: ISO Grád P5, P4;
Le haghaidh imthacaí rolla cúltaca le haghaidh muilte Z: ISO Grád P4,
Difríocht airde comhéadan gach imthacaí ar an seafta céanna Níos lú ná nó cothrom le 0.005mm.
An difríocht idir tiús bhalla imthacaí cóngaracha Níos lú ná nó cothrom le 0.002mm.
3. Fáinne istigh corónach, rásbhealach & rollóirí:Rollóirí barrchaolaithe de TRB: le próifíl logartamach,
4. Comhsheasmhacht próifílí agus méideanna sorcóir
Déantar na rollóirí barrchaolaithe den tsraith dhúbailte agus imthacaí sorcóir barrchaolaithe ceithre shraith a mhonarú de réir lamháltais chomh dlúththoiseacha agus gheoiméadracha go bhfuil siad beagnach comhionann. Soláthraíonn sé seo an dáileadh ualaigh is fearr, laghdaíonn sé torann agus creathadh, agus cuireann sé ar chumas réamh-ualach a shocrú níos cruinne.
5. Saol tuirse feabhsaithe
6. Creathadh torainn laghdaithe
