Background
At present, when a special-shaped blank casting machine is used for casting, two bolts are inserted into inscribed circles on two sides of a dummy bar head to serve as dummy bar, and in order to prevent pulling-off, the casting machine is very low in pulling speed when the casting machine is used for casting. The conventional control method of the amount of the poured water is to spray water with the minimum amount when the billet head enters the cooling zone, and the billet head is cooled to avoid pulling off. Especially, the casting speed of the large special-shaped blank with the cross section (for example 1200 multiplied by 500 multiplied by 120mm) is only 0.2 to 0.4m/min, and under the condition of low drawing speed, the temperature of the blank head is very low, and if the control is not good, the temperature can be lower than 600 ℃. Under the condition of low temperature, the tension leveler cannot straighten because the bending modulus of the special-shaped blank is extremely large. If the height of the casting blank flange is higher, the height of the arc-shaped casting blank which is not straightened possibly exceeds the height of an upper roller of a tension leveler, the casting blank cannot pass through the tension leveler, even the tension leveler is overturned, and the casting flow stops casting.
