摘要
分析了近年来涉及到的高炉用低蠕变高铝砖、陶瓷杯砖、炭砖以及球团回转窑浇注料、炼钢中间包涂料的显微结构、性能及其对使用寿命的影响,就产品的优劣质分析方法、用户对于性价比的认识与误区进行了讨论。认为:对于有长寿命要求的耐火材料必须实行优质优价,不能采用低价中标降低炉衬寿命;对于使用寿命要求不高的产品,没有必要过分追求性能指标,满足使用要求即可;压低耐火材料采购价格,会导致劣质耐火材料流行,最终将损害钢铁行业的发展。
Structures and performances of low creep high alumina bricks, ceramic cup bricks,and carbon blocks for blast furnace,castables for rotary kiln and coatings for tundish and their effects on service lives were analyzed ,the viewpoints and misunderstandings on cost performance of consumers were discussed based on high and inferior quality analyzing method. The results show that the long service life refractories shall be with high quality and high price,the successful bidding with low price will decrease the service life of lining ;for short service life refractories ,the properties index needn＇t be paid more attention, meeting the needs for consumer＇ s application is enough ;decreasing the purchase price of refractories will make inferi- or materials to be popular,which is harmful to the development of steel industrv at last.
