秦皇岛耐火材料厂于今年二月份接受河北省冶金局关于研制锆质定径水口砖的科研任务,仅用两个多月的时间就获得了可喜的成果。填补了我国耐火材料工艺的一项空白。四月下旬,这种错质定径水口砖,在昆明钢铁公司从西德引进的三流小方坯连铸机上进行了工业性生产试验,并与进口西德锆质水口砖作了同色对比试验,试验中第一次一流用秦耐错质水口砖,两流用西德进口砖;第二次,两流用秦耐砖,一流用西德进口砖;第三次全部采用秦耐砖。试验结果,浇铸正常,拉坯拉速稳定,物理性能和使用效果均达到西德同类产品水平。
Qinhuangdao refractory plant in February this year, Hebei Metallurgical Bureau to accept the research on the development of zirconium fixed-diameter nozzle brick research mission, only two months time to get gratifying results. Fill a blank of China’s refractory technology. In late April, this wrong quality nozzle brick, in the Kunming Iron and Steel Company from West Germany imported three-stream billet caster for industrial production test and imported with West Germany Zirconium bricks made the same color contrast test , The first time in the test with Qinshui Qizui Shuizu brick, two streams with West Germany imported brick; the second, two streams with Qin refractory brick, first-class West German imports of bricks; the third use of all Qin resistant brick. Test results, casting normal, drawing speed and stability, physical properties and the use of results have reached the level of similar products in West Germany.
