Description

technical field [0001] The invention relates to the technical field of push plates, in particular to a high-strength, heat-resistant and shock-resistant push plate and a preparation method thereof. Background technique [0002] With the gradual and in-depth implementation of national environmental protection and energy-saving policies, new energy-saving and environmental-friendly pusher kilns have emerged, and the matching kiln furniture materials have developed rapidly. 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, defor...

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 for repairs to repairing, or dismantling the kiln, causing serious losses to the user.

Since the working temperature of the kiln is between 1100°C and 1450°C, to complete the sintering of a product, the push plate for the kiln needs to undergo a process of room temperature-high temperature-room temperature, so that the cycle and relatively frequent thermal shock require The push plate for kiln has excellent thermal shock resistance, and the large load capacity of the push plate requires the push plate to have excellent mechanical strength. In practice, there is often a contradiction between the thermal shock resistance and strength of the push plate, and it is difficult to Simultaneously obtain two pushing plates with better properties
