Forbhreathnú ar bharra cruinne cruach an Earraigh
Tá barra babhta cruach an earraigh oiriúnach do raon leathan d'iarratais earraigh lena n-áirítear spriongaí árasán, bearrtha, sceana, lanna dochtúir, lanna chonaic, uirlisí talmhaíochta, sábha gearrtha adhmaid, shims, sceana, lanna, shims, leicneáin, uirlisí saoirseachta. Nuair a bheidh cóireáil teasa ag teocht EN42, lena n-áirítear ráta na n-amanna téimh, fuaraithe agus maosaithe, etc., de bharr fachtóirí cosúil le cruth agus méid gach comhpháirte. I measc nithe eile le linn an phróisis cóireála teasa tá an cineál foirnéise, meán múchadh, agus áiseanna aistrithe workpiece. Téigh i gcomhairle le do sholáthraí cóireála teasa le haghaidh treoir iomlán maidir le cóireáil teasa steels earraigh.
