Title: Roll for continuous casting machine
Inventor: KAWASAKI YOSHINORI
IPC: B22D11/128
Filed: 1984-07-27
Abstract: PURPOSE:To relieve thermal stress and to extend the life of a roll by engraving U- grooves having stepped parts to the roll surface, attaching sealing plates to the stepped parts to constitute the closed water passage and providing a water feed hole and discharge hole to both ends of the grooves in the axial direction of the roll thereby conducting cooling water from the roll inside to the roll surface. CONSTITUTION:The roll 1 is made into the construction in which the spiral grooves 5 are provided to the surface thereof and in which the water passages 6 connecting to the cooling water hole 4 at the rollcenter are provided to both ends thereof. The sealing plates 7 are spanned on the stepped parts 8 on both sides of the grooves 5 to cap the grooves 5 thereby forming the hermetic or semi-hermetic water passages 9. The cooling water leaks consequently from the slight spacing and arrives at the contact surface between a billet and the roll thereby improving the cooling effect. Since the passages are open on one side, the plates 7 follow up easily the roll expansion. The hermetic type without leakage is sometimes employed according to the kind of steel. In such a case, the plates 7 are made into the waveform or arc-shaped section to absorb thermal expansion. The plates 7 are made lower than the surface of the roll 1 to prevent the contact with the billet and are made of a stainless steel in consideration for corrosion resistance.
