FLS66-35K Partial annealing machine use low votage and pipe surface of big electric current to short circuit anneal machine., the characteristic annealing elevation of temperature speed is quick. It heat few ot the heating element and mgo powder. Part anneal machine aremainly controled by transformer, air operated clamp contact, elastic clamp contact, water cooling system, aerodynamic pressure system and electric appliance of system composes. The machine structure is compact, security convenience operation and high efficiency,it's tubular part annealing production ideal equipment.
