Problems solved by technology

[0002] At present, the vacuum furnaces in our country can only make some small workpieces, and there are still some difficulties in the vacuum heat treatment of some extra-long types, especially for some tube and rod materials, which must realize continuous operation in large batches. As far as the current vacuum furnace is concerned is impossible

Embodiment Construction

[0004] The equipment is mainly composed of a preparation room, a gate valve in the preparation room, a heating room, a cooling gate valve, a vacuum unit, a cooling fan for a raceway feeder, and a feeding car outside the furnace. In the process of operation, first put the material into the preparation room, then open the gate valve, and enter the heating room for heating treatment. When the heating room is heated, the preparation room can continue to add materials to prepare for the second heating. When the heating room After the heating is completed, the gate valve of the cooling room is opened, and the cooling fan is used for cooling, and the materials in the preparation room can immediately enter the heating room for heating, in order to achieve the purpose of semi-continuously.

Abstract

The semi-continuous horizontal long vacuum annealing furnace for vacuum heat treatment consists of one ready chamber with one gate valve, one heating chamber, one cooling chamber with one gate valve, one vacuum machine set, one roller conveyer, one cooling fan, one bogie outside the furnace, etc. The operation process includes loading material to the ready chamber, opening the gate valve in the ready chamber for material to enter the heating chamber, heating in the heating chamber while loading the next batch of material to the ready chamber, opening the gate valve in the cooling chamber for unloading the heat treated material, cooling with the cooling fan, and beginning the next treating period.

Description

technical field [0001] The invention belongs to the field of heat treatment industry, in particular to an elongated vacuum furnace for vacuum heat treatment. Background technique [0002] At present, the vacuum furnaces in our country can only make some small workpieces, and there are still some difficulties in the vacuum heat treatment of some extra-long types, especially for some tube and rod materials, which must realize continuous operation in large batches. As far as the current vacuum furnace is concerned is not possible. Contents of the invention [0003] In the present invention, the heating chamber is divided into multiple zones for control. According to the length of the processed object, more than six heating zones can be designed. Each heating zone realizes independent temperature rise to ensure the furnace temperature uniformity of the set temperature. There is no preparation chamber at the front of the heating chamber, and the preparation chamber and the hea...
