Local resistance heating device with a controlled atmosphere

摘要

A local resistance heating device, with a controlled atmosphere, includes two end members and a mid member. The two end members are respectively connected with an anode pole and a cathode pole. Each end member has an air channel. The air channel of one of the end members is adapted to connect with an output terminal of a gas supplier, and the air channel of the other one of the end members is adapted to connect with a sucking terminal of the gas supplier. The mid member is arranged between the two end members. The two end members and the mid member jointly define a heating room communicating with the air channels of the two end members.
