刮板輸送機使用環境惡劣，工作負荷大，其失效形式主要是自身各部件之間以及與矸石或煤炭的劇烈摩擦而引起的磨損失效，為了提高刮板的耐磨，強度及韌性，DJM選用高錳鋼基高鉻復合陶瓷鑄造制作刮板，采用粉末冶金制芯結合鑄造燒結工藝，在澆鑄工程中利用高鉻復合陶瓷材料降低高錳鋼鋼水溫度，利用高鉻復合陶瓷材料中的合金元素細化高錳鋼晶粒，提高高錳鋼基體性能，充分發揮高錳鋼的加工硬化特點，減少刮板塑性變形，提高抗沖擊能力； 結合高鉻復合陶瓷材料的高耐磨特性，提高刮板工作面的抗磨性能，從而獲得即耐磨且抗沖擊的刮板。

In order to improve the wear resistance and impact resistance of the flight bar, DJM use the composite of high Cr and ceramic on steel base. We adopt the powder metallurgy core making and casting sintering, during pouring the composite of high cr and ceramic is put to reduce the temperature of molten manganese steel, the alloy element in the composite are used to refine the high manganese steel grain to improve the performance of high-manganese steel,  give full play to the capacity of self hardening under impact and improve the ability of impact resistance;
