我厂铸工车间用的铁水包(600kg),以前往往在砌筑后敷上一层焦粉、耐火泥混料,再刷上一层石墨粉涂料。但在使用后,残渣余铁粘包严重,工人清理起来费力、费时。后来,我们在砌筑后敷上一层由石英砂、耐火泥、白炭灰、粘土和适量水搅拌成的混合料,再刷上一层白炭灰。使用后,效果很好,粘包现象大为减少。原来清理残渣余铁需要3小时,而现在仅0.5小时,既省时又省力。该混合料配方为:70/140目石英砂12％左右、40/70目石英砂40％左右、耐火泥24％
I plant cast iron shop with the casting plant (600kg), often in the past, put a layer of coke powder after masonry, fire-resistant mixture of mud, brushing a layer of graphite powder coating. However, after use, the remaining residue iron sticky packets serious workers to clean up laborious and time-consuming. Later, after masonry, we put a layer of mixture of quartz sand, refractory clay, white charcoal, clay and appropriate amount of water, and then a layer of white charcoal. After use, the effect is very good, greatly reduce sticky phenomenon. The original residual iron residue needs 3 hours, and now only 0.5 hours, both time-saving and labor-saving. The mixture formula is: 70/140 quartz sand about 12%, 40/70 quartz sand about 40%, refractory mud 24%
