Ko te hiko kauwhata te nuinga o te hanga ki te hinu hinu me te ngira, ka whakamahia te bitumen waro hei here.He mea hanga na roto i te calcination, te whakahuihui, te pokepoke, te hanga, te tunu, te graphitization me te machining.Small diameter graphite electrode,te awhe diameter mai i te 75mm ki te 225mm, te iti o te diameter graphite electrodes e whakamahia nuitia ana i roto i nga momo mahi ahumahi penei i te konupūmā carbide, te te whakamahine o te carborundum, te whakarewa ranei o nga konganuku onge, me te whakato Ferrosilicon refractory.
