초록 ▼

Continuous casting apparatus is described wherein the temperature of the flexible casting belts in twin-belt machines having two or more main rolls in each belt carriage is controllably elevated prior to contact with the molten metal to improve the casting conditions and the operation of the thin flexible casting belts; the temperature elevation preferably being relatively gradual may be carried out while the travelling belts are approaching the nip rolls or while the belts are in contact with the nip rolls, or both. Zone control of belt pre-heating is disclosed, and control of the coolant streams issuing from the curved nip roll tubes by use of fingernail-like extenders may be provided to aid in pre-heating the belts and in controlling their operation. Intensive infra-red heaters are shown directed at close range toward the casting surfaces of the belts, these heaters serving also to cure and dry any coating material on the belts. Heating of the nip rolls by means of hot fluid, such as steam, is described, with the hot fluid being directed into the interior of the nip roll or being directed into the deep grooves in the nip roll beneath the rear surfaces of the casting belts. Mechanical and thermal sensors may be employed to sense the distortion of the belts and to measure their operating temperatures, these sensors being shown with automatic control of the belt pre-heating action. The apparatus of the invention can be applied to twin-belt casting machines regardless of whether the molten metal is supplied by open pool, closed pool or injection feeding.

In a twin-belt casting machine in which a casting region is defined between opposed portions of the front faces of a pair of revolving endless flexible casting belts and in which the molten metal to be cast is introduced into the casting region to be carried along between the front faces of the belts as it is being solidified, the invention comprising: a plurality of banks of radiant heaters, first support means mounting one of the banks of heaters closely adjacent to the front face of one of the casting belts in a position located before the revolving belt enters the casting region, second support means mounting another of the banks of heaters closely adjacent to the front face of the other casting belt in a position located before the revolving belt enters the casting region, said first and second support means aiming the banks of heaters to direct intensive radiant energy onto the front faces of the respectivE belts at close range for pre-heating the belts before they enter the casting region, a plurality of belt distortion sensors positioned to engage the reverse surfaces of the respective belts, as they travel through the casting region, said belt distortion sensors being arranged to provide electrical output signals as a function of the belt distortions being sensed, and control means for said banks of heaters for controlling the amount of radiant heat energy being applied to the respective belts, said control means being connected to said belt distortion sensors for controlling said banks of heaters as a function of the electrical output signals from said sensors, thereby to minimize the distortion of the casting belts after they begin carrying the molten metal between them in the casting region.
