毛主席说:“检验真理的标准只能是社会实践”。毛主席又教导我们说,“我们不能走世界各国技术发展的老路,跟在别人后面一步一步的爬行。要敢于走前人没有走过的道路,敢于攀登前人没有攀登过的高峰。”我们遵循毛主席的这一教导,在党的正确领导下,全厂广大职工发扬了敢想、敢干、敢闯的革命精神,与有关单位共同协作,在试制成功高铝水泥的基础上,进行了高铝水泥耐火混凝土的试用。 Chairman Mao said: “The standard for testing truth can only be social practice.” Chairman Mao also taught us that “We cannot follow the old road of technological development in all countries of the world and follow the crawling step by step with others. We must dare to take the path that no one has ever traveled before, and dare to climb the peak that no one has ever climbed before.” "We have followed Chairman Mao’s teachings. Under the correct leadership of the party, all employees of the factory have carried forward the revolutionary spirit of daring to think, dare to perform, and dare to carry forward. They have worked together with relevant units on the basis of trial production of high-alumina cement. A trial of high-aluminum cement refractory concrete was conducted.
