通常來(lái)說(shuō),耐火磚的宏觀組織結(jié)構(gòu)是由固態(tài)物質(zhì)和氣態(tài)孔共同組成的非均質(zhì)體。氣孔是影響制品常溫及高溫使用性能的重要因素,特別是在高溫條件下,使制品對(duì)外界侵蝕的抵抗能力大大降低。氣孔形成原困是:耐火磚成型時(shí)物料中的空氣未完全排···

耐火磚的燒制程序是怎樣的?根據(jù)固體物理學(xué)的概念,耐火磚基本可以被看作是不與熔劑物質(zhì)起反應(yīng)的固體材料,因此高溫煅燒在耐火磚生產(chǎn)中是必不可少的,即使對(duì)日益發(fā)展的耐火澆注料和不燒制品,雖然在,雖然在生產(chǎn)過(guò)程中不經(jīng)燒成工序,但···

縱觀近年,我國(guó)的鋼鐵產(chǎn)量上升為世界上第一位。耐火磚產(chǎn)量也是第一位。鋼鐵工業(yè)消耗耐火磚占65%,其他工業(yè)與民用占35%。日本、美國(guó)等鋼鐵工業(yè)使用耐火磚量占65~70%,我國(guó)鋼鐵工業(yè)新技術(shù)水平較低,中小企業(yè)較多。是耐火磚消耗高的一個(gè)···

什么是耐火磚的熱膨脹性?一般界定,耐火磚的熱膨脹是指耐火磚在加熱過(guò)程中的長(zhǎng)度或體積的變化。在耐火磚的使用過(guò)程中,常伴有極大的溫度變化,隨之而來(lái)的長(zhǎng)度與體積的變化.會(huì)嚴(yán)重影響熱工設(shè)備砌體的尺寸嚴(yán)密程度及結(jié)構(gòu),甚至?xí)剐缕觥ぁぁ?/div>
