耐火磚由於為耐熱材料製作，因此廣泛使用於窯爐和各種熱環境，例如陶瓷器以及鋼鐵冶爐等，除了可以直接做為圍體，也可以作為其他材質圍體的塗層。雖然耐火磚可耐受高溫之程度頗佳，但是為了維持高溫環境的可靠性等因素，經過一段時間之使用，耐火磚仍然需要拆除更換，而拆除之耐火磚則一般成為廢棄物，對於環境而言不啻為一負擔，且對於經濟效益而言，耐火磚中仍然有其可使用之材料部分，若貿然拋棄亦屬可惜。 Because refractory bricks are made of heat-resistant materials, they are widely used in kilns and various thermal environments, such as ceramics and steel smelting furnaces. In addition to being directly used as enclosures, they can also be used as coatings for enclosures made of other materials. Although the refractory bricks can withstand high temperatures to a good degree, in order to maintain the reliability of the high temperature environment and other factors, after a period of use, the refractory bricks still need to be removed and replaced, and the removed refractory bricks generally become waste.
