什么是水平连铸的拉坯曲线？拉坯曲线是指在“拉坯过程”中的速度图。目前使用较多的有正弦曲线与双折梯形曲线两种，前者波形产生容易，但启铸加速度为最大值，对铸坯凝固前沿铸壳易拉裂；后者启铸加速度小，动载荷小，拉坯工作更可靠，但控制信号波形电路较复杂些。什么... What is the level of continuous casting drawing curve? Punch curve refers to the “drawing process” in the speed chart. At present, there are two kinds of curves with sinusoidal curve and birefringence, the former is easy to generate, but the maximal acceleration of casting is easy to crack the casting shell before the solidification of the slab. The latter has a small accelerating acceleration and small dynamic load , Pull the work more reliable, but the control signal waveform circuit more complicated. what...
