Problems solved by technology

In the process of product sintering, it is necessary to place the product to be sintered directly or indirectly on the push plate used in the kiln, and the product placed on the push plate is moved by the propulsion system according to the technological requirements of the product, and the product is finished in the furnace. During the sintering process, the push plate is one of the important parts of the kiln, and its performance directly affects the service life of the kiln. If the push plate breaks, deforms or falls off during use, the arch kiln will occur. Accidents, that is, the channel is blocked by the push plate, and the push plate machine cannot be pushed. The consequences caused by this may range from stopping the kiln fo
