连铸板坯生产中,保护渣具有对钢水绝热保温、防止氧化、润滑与去除夹杂物的作用,因而在保证生产顺行和提高铸坯表面质量方面起着极为重要的作用。保护渣检测的一般项目为:化学成分;熔点、熔速;1300℃时的粘度;水分;物性状态(如粒度组成、铺展角)等。经过努力,检测保护渣熔点、熔速用GX—Ⅱ型高温物性测试仪,检测保护渣粘度的粘度仪,水分检测仪,均已在技术中心钢研所完成安装、调试工作。调试过程中,对炼钢厂目前使用的两种保护渣进行了熔点、熔速、粘度、水分测定,检测结果与在马钢钢研所及北京钢铁研究总
In the continuous casting slab production, the mold flux has the function of adiabatically keeping the molten steel, preventing oxidation, lubricating and removing the inclusions, and thus plays an extremely important role in ensuring the smooth production and improving the slab surface quality. The general items of mold flux testing are: chemical composition; melting point, melt speed; viscosity at 1300 ° C; moisture; physical properties (such as particle size composition, spreading angle) After hard work, testing melting slag melting point, melt speed with GX-Ⅱ-type high temperature properties tester, viscometer viscosity measuring viscometer, moisture detector, have been completed in the technical center Steel Institute installation and commissioning work. Debugging process, the two currently used in the steel mills melting point, melting velocity, viscosity, moisture determination, test results and test results at the Institute of Steel and Beijing Institute of Steel
