◆Guillotine blades
By quitting the traditonal inlaying method in a coke furnace,the new inlaying process improves with a tail gas furnace.Electric heating brings equal and accurate temperature degrees,and gas protection helps achieve no oxidized welding,therefore tipped area welded onto base metal without such defects as imcomplete or unthorough welding.Morever,welding and heat treatment are done in the same heating & cooling system,knives therefore brightly quenched with an equal hardness up to HRc63-65.
Deep cryogenic treatment at liquid-nitrogen temperatures (-196°C) further improves the knife a lot on steel hardness and red hardness,wear and impact resistance ability,thus giving a liftime 2-3 times longer than a knife normally treated.
