连铸中间罐的耐火村由保护材料和工作材料组成。保护层多半用的是粘土砖或高铝砖,工作层为碱性喷补材料或绝热板。瑞典Hoganas公司开发了一种新的喷补材料,这种材料以橄榄石为基础,它由镁橄榄石和少量正硅酸铁组成。镁橄榄石喷补材料含有一种有机纤维添加料,此添加料能减少应用中的回跳现象并使喷补料很快加热,而不因气流而剥落。这种喷补材料含(％):57MgO、34SiO_2、7Fe_2O_3和1Al_2O_3。其耐火度在1850℃为SK38,计算(体积)密度为2300kg/m~3。通常,此工作层的厚度为25mm,
The refractory village of the continuous casting intermediate tank consists of protective material and working material. The protective layer is mostly used clay brick or high alumina brick, the working layer is alkaline gunning material or insulation board. Hoganas, Sweden, has developed a new gunning material based on olivine, which consists of forsterite and a small amount of ferrosilicate. Forsterite refractories contain an organic fiber additive that reduces back-bouncing in the application and heats the sprayer very quickly without exfoliation due to airflow. The gunning material contains (%): 57MgO, 34SiO_2, 7Fe_2O_3 and 1Al_2O_3. The refractoriness is SK38 at 1850 ° C and the calculated (volumetric) density is 2300 kg / m ~ 3. Generally, the working layer has a thickness of 25 mm,
