After upgrading the band saw quenching furnace heating power adjustable, accurate temperature control, good band saw quenching straightness, effectively eliminating the band saw blade produced "S" bend. Band saw blade after quenching only once straightening. Finished product rate band saw blade from the original 78% to about 90% now.
