济南铝板铸轧速度介绍

济南铝板http://www.brujobike.com/的铸轧速度是指铸轧铝板的出板速度。铸轧速度与铸轧辊线速度相比有一定的前滑量,辊径不同,前滑量不同,前滑量一般为6%-10%。铸轧速度是由液穴确定的,当铸轧速度增加到某一临界值的时候,结晶前沿朝着铸轧辊出口平面移动,由于冷却不及时,液穴加深,所以铸轧速度存在一个极限速度,就是稳定轧制的最大速度。
Jinan aluminum sheet aluminum casting casting speed is the speed of the board. Casting speed and casting roll line speed compared to a certain amount before the slide, different roller diameter, before sliding a different amount, before

sliding the amount is generally 6% -10%. Casting speed is determined by the liquid hole, when the casting speed is increased to a critical value, the crystallization front moving toward the exit plane roll casting, since cooling is not timely, Sump deepened, so that there is a casting speed limit speed is stable rolling maximum speed.
   
济南铝板http://www.brujobike.com/轧制过程中,要保持连续铸轧的稳定性,主要是调整铸轧速度,铸轧速度过大,溶融金属冷却不足,呈液态状被轧辊带出,铸轧速度过小,铝板会过度冷却,会造成液态金属凝固与铸嘴内,破坏铸轧过程。
Jinan aluminum rolling process, to maintain the stability of continuous casting, mainly to adjust the casting speed, casting speed is too large, the molten metal inadequate cooling is liquid state is roll out, casting speed is too small,aluminum will be excessive cooling, will cause the liquid metal solidification and casting in the mouth, the destruction casting process.
