Problems solved by technology
[0002] The heating furnaces in the prior art all use one temperature point for temperature control, and it is difficult to achieve uniform temperature distribution on the circumference of the heating furnace. The processing technology of most products has a high degree of uniformity in the heating temperature in the circumferential direction of the heating furnace. requirements, which cannot be met by existing technologies
Moreover, the prior art also has the problems of poor temperature control accuracy and large temperature distribution deviation.

The invention relates to the technical field of heating furnace manufacture, and discloses a hollow horizontal heating furnace. The hollow horizontal heating furnace comprises a heating furnace, a moving platform, measuring devices and a control module; the heating furnace is installed on the moving platform, the inner wall of the heating furnace is sequentially divided into at least two heating sections in the direction from a heating furnace inlet to a heating furnace outlet, each heating section is divided into at least two temperature zones in the circumferential direction of the heating section, heating tiles are installed in each temperature zone, at least one heating section, the heating furnace inlet and the heating furnace outlet are each provided with the corresponding measuringdevice, and the heating tiles and the measuring devices are connected with the control module. The invention further discloses a control system of the hollow horizontal heating furnace and a control method for the control system of the hollow horizontal heating furnace. The hollow horizontal heating furnace has the beneficial effects that the temperature control zones can be subdivided, precise temperature control can be achieved, and it is guaranteed that the temperature in the heating furnace is evenly distributed.
Description
technical field [0001] The invention relates to the technical field of heating furnace manufacturing, in particular to a hollow horizontal heating furnace and its control system and control method. Background technique [0002] The heating furnaces in the prior art all use one temperature point for temperature control, and it is difficult to achieve uniform temperature distribution on the circumference of the heating furnace. The processing technology of most products has a high degree of uniformity in the heating temperature in the circumferential direction of the heating furnace. Requirements, the existing technology can not meet its requirements. Moreover, the prior art still has the problems of poor temperature control accuracy and large temperature distribution deviation. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the prior art above, and provide a hollow horizontal heating furnace with a subdivided tempe...
