摘要： PROBLEM TO BE SOLVED: To provide roller method and equipment of rolling mills for sheets or plates capable of improving a edge drop vastly, reducing its variance and continuing rolling operation efficiently, without forming surface defects. SOLUTION: The rolling mills for sheets or plates that comprise a pair of top and bottom work rolls that roll sheets or plates, intermediate rolls that support the work rolls respectively and back-up rolls that support the intermediate rolls respectively. In the rolling method of these mills where part of the work rolls near one end is tapered and they are arranged oppositely along roll axis, there are the advantages that in rolling sheets or plates with same width, the position at the axial direction of the work rolls can be adjusted to a pre-determined position, and the crosswise thickness distribution of rolled stock can be controlled due to changing the position at the axial direction of the intermediate rolls.

摘要： PURPOSE: To enable generating resonance on a material and to increase the accelerating effect of plastic deformation by vibrating by making vibration at very high frequency at the time of plastically working the materials. CONSTITUTION: By providing cylinders 4 for vibrating means for adding vibration to accelerate the plastic deformation of the materials separately from cylinders 3 for compressing means for loading main working force, the compressing means which require a large thrust and stroke and the vibrating means whose thrust and stroke may be smaller but which require high frequency are independently composed and vibration is directly added to the material 1 without anvils 2. The frequency at the vibration limit of the vibrating means is increased and the material is vibrated at the resonant frequency of the material or the nearer frequency to that, so plastic deformation is more accelerated and the material is uniformly deformed and the increment of the amount of compression, reduction of the force and energy which are required to work, miniaturization of the device, improvement of working accuracy, etc., are realized.

CONSTITUTION:The intermediate rolls 6, 7 are disposed between the work rolls 1, 2 and backup rolls 3, 4 at the time of rolling in a left direction in reversible type rolling. The rolls 6, 7 are movably constituted to act bending force on cylinders 18, 19 containing shift blocks 14, 15. Cylinders 16, 17 are contained the shift blocks 14, 15 provided to shaft parts 10. The cylinder 16 side is emerged and the cylinder 17 side is returned to shift the rolls 6, 7 toward the position of a broken line at the time of the ensuing rolling in the right direction. The horizontal force acting on the work rolls 1, 2 is decreased with the simple device by the above-mentioned mechanism.

摘要： PURPOSE:To prevent the clogging of a nozzle and the splashing of molten steel at the start of casting and to stabilize casting by making the flow rate of charging of the molten steel at the start of continuous casting smaller than a specified flow rate. CONSTITUTION:A rod 13 which supports and guides a tundish stopper 4 and a beating bar which forms said rod in one body and is mounted in one body to a lever 12 and the rod 13 are moved upward by a cylinder 16 at the start of continuous casting. The rate of the ascending is regulated by a cylinder 1 to make the rate of charging of molten steel smaller than a specified flow rate. The controlling is carried out until the tip part of a charging nozzle 9 disposed in the mold is immersed in the molten steel. By said charging method for molten steel, the molten steel is killed without splashes, and a large amt. of the molten steel can be charged satisfactorily, whereby high-speed casting is realized.

摘要： PURPOSE:To cool and support belts which travel synchronously with an ingot and constitute a mold at an economical flow rate of fluid by making the static pressure for supporting said belts lower on the upstream side of the mold and making the flow rate of the cooling fluid larger on the upper stream side. CONSTITUTION:The molten steel 2 in a tundish 1 passes through a nozzle, and flows into a synchronizing type continuous casting machine constituted by an outer belt 3, an inner belt 4 and side blocks 14 where the steel forms a solidifies shell which is drawn out as an ingot 15. The belt 3 is engaged to the outside circumferences of guiding rollers 5, 6, 7, and the belt 4 engages with the outside circumference of guiding rollers 8, 9, 10. Hydrostatic bearings 13 are provided behind the respective rollers to support and cool the belts which receive the static pressure of the steel 2. In the mold, the static pressure of the molten steel is low and the surface temp. of the ingot is high on the upstream side, and the static pressure of the molten steel is high and the surface temp. of the ingot is low on the lower stream side; therefore, the bearings 13 are made into the construction wherein the flow rate of the cooling fluid is increased on the upstream side and the effect of supporting is high on the downstream side.

摘要： PURPOSE:To disconnect the contact between belts and guide members with a water film, cool an ingot via the belts and improve quality by supplying a coolant of the pressure equal to that of molten metal to between the belts opposing to each other with the ingot in-between and the guide members on the rear side thereof. CONSTITUTION:The molten metal 2 in a tundish 1 passes through a nozzle and is supported by the ingot guide devices constituted of inside, outside belts 3, 4, 5, 6. At this time, cooling water is supplied through the water feed ports 28 of the guide devices and enters cooling water chambers 30, from which it passes through water flow ports 29 out into plural recesses 27, after which it forms a high-speed cooling water film 26. The belt 5 is supported by the pressure of the cooling water equal to the static pressure of the meral 2, and an ingot 24 is cooled by the belt 5, by which the thickness of a solidified shell 25 is increased. This ingot is discharged to the outside of the machine. The same holds true of the outside belt 6 side, the inside belt 3 side and the outside belt 4 side.
