快速上铸的发展对钢锭模和铸铁底盘提出了新的要求。为了解决底盘被部分粘掉造成损坏问题,已有不少方法。有些已经在工业上付诸使用,如采用放热修补料修补底盘;在底盘上镶嵌耐火砖块,在底盘表面涂刷耐火涂层等。我国的快速上铸工艺还处于开始发展阶段。武汉钢铁公司一米七工程硅钢上铸工艺要求采用底盘砖。为此,我们对上铸用底盘砖进行了研究试制和使用试验。 1. 研制 1·1 选材根据上铸底盘砖的使用条件进行 Rapid casting on the development of ingot mold and cast iron chassis put forward new requirements. In order to solve the problem of damage to the chassis is partially sticky off, there are many ways. Some have been put into industrial use, such as the use of exothermic repair materials to repair the chassis; inlaid firebrick in the chassis, the surface of the chassis coated with fire-resistant coating. China’s rapid casting process is still in its infancy. Wuhan Iron and Steel Company one meter seven projects on the silicon steel casting process requires the use of chassis tiles. To this end, we have on the casting of the chassis brick research trial and use of the test. 1. Development 1.1 Selection of materials under the conditions of use of the chassis cast brick
