Those issues have been experienced in a wide range of industrial scenes, from processing raw materials, making refractories to relining furnaces, handling after-use refractories. The key substances dealt with in this paper include, for example, suspended particulate, SOx and other exhaust gaseous emissions, hexa-valent chromium, and dioxin. The measures so far taken to avoid or reduce their influences upon environments are described with some future problems to be tackled.展开更多
文摘Major environmental problems related to refractories are discussed based on their historical studies mostly in Japan.
