摘要
日本采用回转窑煅烧白云石，以２ＣａＯ·Ｆｅ２Ｏ３包覆煅烧白云石颗粒表面，并采取涂油措施，以减少粉尘，防止水化。煅烧白云石具有长期耐水化性及优良的耐腐蚀性，主要用于电炉耐火材料。在东京钢铁公司８０ｔ超高功率电炉上使用，大修一次炼２５００～３０００炉，比使用镁砂寿命延长一倍。
Using of revolving kiln to Calcining dolomite,to cover its grian surface with 2CaO·Fe 2O 3,and to coat oil on its surface,the dust and hydrate of dolomite are lowed and protected in Japan.The calcined dolomite has excellent resistance to hydrate and resistance to erosion,it is manly to use in electic furnace.This refactory material can melt 2500-3000 heats steel only once great repair and its service life is one times long than magnesite through using in super high frequency furnace of 80t and over 80t in Tokyo Iron and Steel company
