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
The present invention is a kind of extended type vacuum oven in heat treatment industry field, particularly vacuum heat treatment.
Background technology
At present the vacuum oven of China can only be made some less workpiece, and also there is certain degree of difficulty in the vacuum heat treatment of some speciality types, and particularly some pipe bar materials more also must be realized working continuously in batches, can't realize with regard to present vacuum oven.
Summary of the invention
The present invention is divided into multi-region with heating chamber to control, and can be designed to six more than the heating according to the length of processing object, and each heating zone realizes that independent temperature raising is to guarantee to set the temperature uniformity of temperature.The anterior offhand chamber of heating chamber is separated by vacuum flashboard lock between preparation room and the heating chamber, when heating chamber when heating preparation room can open charging and can carry out heating chamber and heat.The rear portion of heating chamber is a cooling room, and the density of cooling room is basic identical with heating chamber.A plurality of cooling airs and interchanger are arranged at top, are also separated by middle slide valve between cooling room and the heating chamber, and slide valve is delivered to material in the cooling room and cooled off in the middle of can opening after the workpiece heating of heating chamber finishes, slide valve in the middle of closing, and heating chamber can heat.
Embodiment
This equipment mainly is made up of preparation room, preparation room slide valve, heating chamber, cooled gate valve disk valve, vacuum unit, rollaway type feeder cooling blower, the outer truck of stove etc.The preparation room of in operating process, earlier material being packed into, open slide valve then, enter heating chamber and carry out heat treated, when heating chamber heated, preparation room can continue again to feed in raw material, for heating is for the second time prepared, after finishing, the heating chamber heating opens the cooling room slide valve, cooled off by cooling blower, the material of preparation room can enter heating chamber immediately again and heat, and reaches semi-continuous purpose successively.
Claims (2)
1. heating chamber is heated by six districts, and the heating chamber entire length adds 6000mm.
2. in the front and back of heating chamber preparation room and cooling room are arranged.The charging discharging need not heating chamber is cooled down promptly existing.
