1958年,随着鋼鉄工业大跃进,耐火材料的生产也有着很大的跃进。产量此1957年增长了三倍,这是高速度的发展。在耐火材料飞跃的发展中,“小土群”发揮了很大的威力,产量约占60％,新的生产单位发展极快。在創造土的和土洋結合的机械設备方面,成绩亦很显著:在粉碎方面有木凿輪石碾机,小鋼磨,木壳球磨机,混凝土球磨机;成型方面:有夹板打砖机,翘板打砖机。在烧成的爐型方面出现“跃进式倒焰窑”,“簡易隧道窑”。“大洋群”方面,重点企业耐火材料的产量有了急剧的增长,在生产技术方面也有了极快的提高和发展:重庆钢铁公司两个耐火材料車間冲破了几十年的“技
In 1958, with the steel industry giant leap forward, refractory production has also made great leaps. This production in 1957 tripled, which is a high-speed development. In the development of refractories, “small soil group” has played a great power, the output of about 60%, the rapid development of new production units. In the creation of soil and marine machinery and equipment, the results are also notable: In the crushing aspects of a wood chisel wheel mill, small steel mill, wood shell ball mill, concrete ball mill; Molding: There are plywood brick machine, Rocker brick machine. In the firing furnace type appeared “leaping inverted kiln”, “simple tunnel kiln.” “Ocean Group”, the key enterprises refractory production has been a dramatic increase in production technology has also been an extremely rapid increase and development: Chongqing Iron and Steel Company two refractory workshops broke through several decades of "technology
