机械封顶的和不含铝的低碳沸腾钢,在某种程度上符合搪瓷板钢的要求(高塑性、无鱼鳞特殊缺陷)。苏联马钢搪瓷器皿车间装备了自动冲压线,要求向该车间提供由2500毫米宽带钢热轧机和冷轧机生产的冷轧板卷,然后在纵切机上进行分卷。搪瓷板钢由双床平炉冶炼,出钢过程中往钢包内加锰铁脱氧。考虑到真空处理过程中的温降,出钢前的钢水温度比类似的一般沸腾钢高20～30℃。在真空处理装置上进行真空脱碳,使真空室内的残余压力小于0.26千帕。试验研究表明,仅仅真空脱碳不能获得
Mechanical capping and non-aluminum low carbon boiling steel, to some extent in line with the requirements of enamelled steel (high plasticity, no scale defects). The Soviet Union’s Masteel Enamelware Workshop was equipped with automatic stamping lines that required the plant to supply cold-rolled coils from 2500mm wide strip hot-rolling mills and cold-rolling mills, which were then rolled on slitting machines. Enamel steel plate from flat furnace smelting, tapping process to the ladle plus ferromanganese deoxidation. Taking into account the temperature drop in the vacuum process, the temperature of molten steel before tapping is 20-30 ° C higher than that of similar normal boiling steel. Vacuum decarburization was performed on the vacuum processing unit to make the residual pressure in the vacuum chamber less than 0.26 kPa. Experimental studies show that only vacuum decarburization can not be obtained
