我厂从1961年推广炉渣内燃烧砖以来,经过两年多的生产实践,获得了良好效果:每万块红砖的煤耗量已由1961年的1,768公斤降到1962年的982公斤,1963年上半年又继续降到386公斤(实物煤);更为重要的是,解决了我厂粘土塑性大,干燥敏感性强,严重影响砖坯干燥质量的技术关键,从而使我厂红砖的质量得到稳定和提高,砖的抗压、抗折强度均达 Since our factory promoted slag-fired bricks in 1961, after more than two years of production practice, good results have been achieved: The coal consumption per 10,000 blocks of red bricks has dropped from 1,768 kilograms in 1961 to 982 kilograms in 1962, 1963 In the first half of the year, it continued to drop to 386 kilograms (in kind coal); more importantly, it solved the technical key of the large clay plasticity and strong drying sensitivity of our factory, which seriously affected the drying quality of bricks, so that the quality of our factory’s red bricks was obtained. Stable and improved, the compressive and flexural strength of the brick reaches
