される。 By introducing this molten substance 1 between the belts 3, it is transferred to the outside (coolant flow path 70) of the belt 3.
A bending force acts on the side). This force is the pressure due to the weight of the molten material 1, and as shown in FIG . The pressure (P s ) of No. 31 is expressed as P s =γ×h.

させるように作用する。 However, Ps : Pressure (Kg/cm 2 ) h: Distance (cm) γ: Density of molten substance (Kg/cm 3 ) This pressure distribution is also shown in FIG. In this figure, the pressures on the belt surface 31 at points separated by distances h 1 and h 2 from the free surface h 0 −h 0 of the molten substance 1 are respectively
If P s1 P s2 , the differential pressure between them (△P s ) is △P s
=P s2 −P s1 , and this quantity is the distance between two points (△h)
and the density γ of the molten substance 1. (△P s =△
h x γ), the pressure due to the weight of these molten substances 1 acts to spread the belt outward (toward the coolant flow path 70 side), bending the belt 3 or causing the belt surface 3 to
2 and the back up fin 60 of the refrigerant flow path 70, thereby increasing the driving force of the belt 3.

イパス弁である。 On the other hand, the flow pressure of the refrigerant acts on the belt surface 32 on the side of the refrigerant flow path 70 so as to push the belt 3 inward (toward the molten substance 1 side) and bend it. That is, in FIG. 7, from the refrigerant supply tank 91 to the refrigerant supply pump 7
3, the refrigerant is supplied to the refrigerant rectifying tank 50 via the inlet valve 75 and the inlet duct 71. The refrigerant further passes through the inlet flow path 51 and flows into the cooling refrigerant flow path 70, absorbing heat from the belt 3 and passing through the outlet flow path. 52 and is discharged to a discharge tank 92 via an outlet duct 72 and an outlet valve 76. Note that 74 in FIG. 7 is a bypass valve.

0 in the inlet flow path 51 and P w1 in the outlet flow path 52.
A pressure of P w2 is generated and a pressure difference of ΔP w is generated between the entrance and exit of the refrigerant flow path, and these act to bend the belt 3 inward (toward the molten material 1 side).
第７図には冷媒の流動に伴つて生ずるベルト表

口間の距離を△ｈとするその間の圧力差（△Pw）
は次のように表わされる。 FIG. 7 also shows the pressure distribution on the belt surface that occurs as the refrigerant flows. The pressure difference between the inlet and outlet of the refrigerant flow path 70 (△P w ) where the distance between them is △h
is expressed as follows.
△Pw＝△Pw〓＋△Pwl
△Pw〓＝△ｈ×ρ （冷媒の自重による圧力）
△Pwl＝ρ／２V2o×ρ（流動抵抗）
但し、ρ：冷媒の密度（Kg／cm3）
Vo：冷媒の流路７０内流速（cm／ｓ）
ρ：冷媒流路の抵抗係数
△ｈ：入口流路と出口流路間の距離
（cm）
また、出口流路５２の圧力はPw2は出口弁７６
の調整にて制御でき、従つて、入口流路５１の圧
力Pw1（Pw1＝Pw2＋△Pw）も自ずと決まる。 △P w = △P w 〓＋△P wl △P w 〓=△h×ρ (Pressure due to refrigerant's own weight) △P wl = ρ/2V 2 o×ρ (Flow resistance) However, ρ: Refrigerant density (Kg/cm 3 ) Vo: Flow velocity of refrigerant in flow path 70 (cm/s) ρ: Resistance coefficient of refrigerant flow path △h: Distance between inlet flow path and outlet flow path (cm) Also, outlet flow path 52 The pressure of P w2 is the outlet valve 76
Therefore, the pressure P w1 (P w1 =P w2 +△P w ) of the inlet flow path 51 is also determined automatically.

The pressure (P s ) that acts to push the belt 3 of the molten substance 1 outward and bend it, and the pressure (P w ) that pushes the belt 3 inward and bends the coolant 7 are applied to the inlet flow path of the coolant flow path 70 . By adjusting and controlling the resistance between the outlet valve 76 and the back up fin 60 of the cooling refrigerant channel so that the resistance is equal between the belt 51 and the outlet flow path 52, deflection of the belt 3 is prevented, and the quality of the casting is improved. Not only does this improve the belt life (prevention of wrinkling and cracking), it also extends the life of the belt, and furthermore, the driving force of the belt is reduced due to a reduction in the belt sliding surface pressure, which is a significant effect.
