Embodiment
[0023] A temperature control method for a mesh belt furnace, according to the set target temperature T 0 , through the following calculations, the power of the burner is adjusted in real time, as follows.
[0024] In the cooling state of the furnace body, adjust the power of the burner to k·W max , record the change of furnace temperature T with time t, and obtain the T-t curve; Wherein, the T value is to need to control the temperature that the temperature sensor 6 in the space range that reaches target temperature takes the average to obtain; k is a constant, at 0.05 ~0.08 range, W max is the maximum total power of the burner.

The invention belongs to the technical field of mesh belt furnaces, and particularly relates to a temperature control method of a mesh belt furnace. According to the temperature control method of themesh belt furnace, on the basis of actually measuring characteristic parameters of the mesh belt furnace, continuous regulation and control are combined with pulse regulation and control, and a temperature control algorithm which is better in anti-interference capacity and accurate and stable in temperature control is obtained. In the actual measurement process, the anti-interference capability ofthe method is remarkably superior to that of a conventional PID control method.
Description
technical field [0001] The invention belongs to the technical field of mesh belt furnaces, and in particular relates to a temperature control method for mesh belt furnaces. Background technique [0002] Mesh belt furnace is a commonly used heat treatment equipment in the metal processing industry. For example, it can be used for normalizing heating of metal parts. It has the advantages of convenient operation, low cost, and continuous operation in large quantities. The existing mesh belt furnace still has certain deficiencies in the accuracy and stability of temperature control, especially in the case of external pulse interference, the temperature of the furnace body fluctuates greatly and the recovery time is long, which has a certain adverse effect on metal processing . Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a temperature control method for a mesh belt furnace, aiming at improving the temperature c...
