流槽、浇杯是连续铸管浇注系统的主要组成部分。由于连续铸管的金属液连续浇注,因此浇注系统所用的流槽、浇杯,经受高温铁水冲刷作用的时间很长,每次3～4分钟。过去用钢板或铸铁制成流槽、浇杯的外壳,内搪耐火衬料,烘干后涂涂料(图1a)使用。每次使用后冲刷严重并扒坏,造成浇流孔尺寸不准,须浇水冷却,经修理烘烤后才能再用。使用次数少,修理工作量大,并影响浇注质量。
Chute, pouring cup is a continuous casting pipe casting system is the main component. Due to the continuous pouring of molten metal continuous casting pipe, pouring system used in the runner, pouring cup, subject to high temperature hot metal flushing time is very long, each 3 to 4 minutes. In the past made of steel or cast iron slot, pouring cup shell, lining lining refractory lining, coating after drying (Figure 1a) use. After each use of serious erosion and Pa bad, causing the size of the pouring hole is not allowed to be water cooling, the bake before re-use. Less use, repair workload, and affect the casting quality.
