摘要： PROBLEM TO BE SOLVED: To provide a device and a method for preheating an immersion nozzle for continuous casting, by which device and method, the immersion nozzle can be efficiently and uniformly heated.
SOLUTION: The immersion nozzle 11 is used to pour molten steel from a tundish of a continuous casting machine into a casting mold. Before the immersion nozzle 11 is arranged on the tundish, the immersion nozzle 11 is preheated beforehand. The immersion nozzle 11 is inserted into an induction coil 22 having an inside diameter larger than the outside diameter of the immersion nozzle 11 except its upper end portion. When the immersion nozzle 11 is induction-heated by the induction coil 22, the immersion nozzle 11 is heated up to a prescribed temperature while relatively moving the immersion nozzle 11 or the induction coil 22 up and down.

摘要： PURPOSE:To exactly change upper and lower back-up rolls by a simple mechanism by incorporating a pressure reducing circuit in a roll supporting frame and an oil hydraulic mechanism. CONSTITUTION:By operating a cylinder 8, the fixed lower back-up roll 1 is placed on a truck 4 and transported to a temporary position in a housing 10 together with the upper back-up roll 6 which is stacked up above the lower back-up roll 1 through a roll supporting frame 5 and in a position where is offset by the quantity of X in the advancing direction from the position of the lower back-up roll 1. Next, by operating a circuit 15 for low-speed operation, the upper and lower back-up rolls 1, 6 are advanced in the interior of the rolling mill at a low pressure with the hydraulic cylinder 8. The roll supporting frame 5 is elastically deformed in the axial direction, a chock 6a is pressed against the housing 10 and further the chock 1a of the lower back-up roll 1 is pressed against the housing 10. Further, the gaps between the arm parts of the chocks 1a, 6a of the upper and lower back-up rolls 1, 6 and the housing 10 become zero. In this way, the play of the back-up rolls 1, 6 in clamping mechanisms are eliminated.

摘要： PURPOSE:To reduce an initial breakaway force of vent score formed around welding portion where a pull ring is attached, by maintaining the distance between the uppermost and the lowermost portions of vent score laterally extending along the breakaway direction, below given value. CONSTITUTION:On a lid of full-easy openable can, a vent score 6 is notched on the opposite side of an open score 2 relative to the welding point 5 of a pull ring 4. The vent score comprises an arcuate portion 6a surrounding the welding point and an approximately linear portion 6b laterally extending from the arcuate portion. A distance between the linear portion and a line passing through a innermost point 6c of the arcuate portion and parallel with the linear portion, ranges within 1.5mm. When the pull ring is pulled up, a bending strength of a lid opening piece 3 in the vicinity of the arcuate portion is reduced locally due to the existence of the laterally extending linear portion. As a result, a breakaway stress of the vent score is concentrated to the innermost point 6c so that only a small force is required to commence the breakaway of the vent score.

摘要： PURPOSE:To enhance can openability without changing the residual thickness of a score, by mainly providing single or plural whisker-like auxiliary scores on the single side of an opening in symmetric relation to the axis in a tear direction so as to start from the initial opening start point of the score. CONSTITUTION:A score 2 is carved in an easy open can lid 1 and the part surrounded by said score 2 becomes an opening piece 3. A projection is formed to a part of said opening part 3 by press molding and, after a pull knob piece 4 is engaged with the projection, said projection is caulked to form a fixing part 5 having the pull knob piece 4 mounted thereto and the initial opening start point 2a of the score 2 is set as the starting point to provide one whisker- like auxiliary score 7 along the Y-Y axis parallel to a tear direction on an opening side. By forming this whisker-like auxiliary score 7, the rigidity of the opening piece 3 at that point lowers locally and the deformation thereof becomes easy and stress concentration at the initial opening start point 2a is promoted and the initial opening start point 2a can be opened by small force.

摘要： PURPOSE: To enable complete descaling at conventional descaling pressure by providing a leveler on the upstream side o descaling nozzles. CONSTITUTION: After steel 1 is bent with the leveler rolls 6 of a leveler 5 and its camber is straightened, descaling is executed by water jets from movable descaling nozzles 4. The pressure of the water jet is 150kg/cm that is conventionally usually adopted. Descaling headers 3 are vertically movable and set to a height suitable to descaling for every materials. Then, the descaling device is made to approch the material, so the scale is completely removed by taking the distances from the material as respectively . Even an Si-scale, for example, which is not conventionally removable because of its strong adhesion to the material is removed.

摘要： PURPOSE: To enable the diagnosis of passing performance at the time of rolling and the control of mechanical deteriorating tendency of a rolling mill by measuring a force for shifting a roll in the axial direction by means of a pressure receiving cylinder and calculating a thrust load and monitoring. CONSTITUTION: A force for shifting a roll in the axial direction is received by a cylinder 1. The pressure of the cylinder 1 is measured by a pressure detector 3, and a thrust load is calculated by a computer 4 based on the area and pressure of the cylinder. When mechanical backlash caused by wear and corrosion takes place in the components of the rolling mill, the axial direction of the roll does not become perpendicular to the rolling direction. Unless they are precisely vertical to each other, a thrust load is generated in the direction of the roll axis as the component of frictional force in rolling. Abnormality of a rolling mill is found by monitoring the thrust load.
