The present disclosure relates to a status monitoring system and control method for a mesh belt furnace for ceramic sintering. The system includes an acquisition layer, an analysis layer and a regulation and control layer. Image data of products conveyed in the mesh belt furnace is acquired by the acquisition layer, and acquired product image data is further segmented to obtain product images. The analysis layer synchronously receives the product images obtained by segmentation in the acquisition layer, and analyzes a product sintering status corresponding to each group of product images based on the product images. Image data acquisition on sintered products in the mesh belt furnace allows primary data to be provided for monitoring an operation status of the mesh belt furnace; then analysis based on the acquired product image data allows to determine qualification of output products in the mesh belt furnace and evaluate overall quality thereof.

Direct flame preheating section for continuous metal strip processing lines, comprising a connecting zone between an active zone provided with burners capable of operating in no flame mode and a recuperative zone for preheating the strip by exchange with combustion fumes originating from the active zone, the connecting zone having chambers capable of orienting the flow of fumes such that they flow head-on relative to the strip when exiting the active zone and entering the recuperative zone depending on the direction of flow of the fumes.
