白云石經过烧炼后是一种很好的碱性爐衬材料。但是由于存在着以下問題,沒有被广泛采用。一、熟白云石吸水后,其中的氧化鈣(C_aO)就变成氢氧化鈣(C_a(OH)_2)而粉化,失去了作为耐火材料的一切性能,因此熟白云石儲存不易,同时儲存时間不能太长。二、不能用含水的材料做粘結剂,必须使用瀝青或煤焦油,这就給修爐工作带来了很不好的劳动条件。 Dolomite after burning is a good alkaline lining material. However, due to the following problems, it has not been widely adopted. First, cooked dolomite water absorption, in which the calcium oxide (Ca_aO) becomes calcium hydroxide (C_a (OH) _2) and pulverized, losing all performance as a refractory material, so cooked dolomite storage is not easy, while storing Time can not be too long. Second, you can not use water-based materials as a binder, you must use asphalt or coal tar, which gives repair furnace work has brought very bad working conditions.
