摘要： PURPOSE: To high efficiently descale for obtaining a steel strip with an excellent surface condition, by cooling a hot rolled, high temperature strip in a water bath, rolling this strip with a prescribed condition, and then, applying a mechanical treatment.
CONSTITUTION: A hot rolled, high temperature steel strip in a coil form is dipped into a water bath and cooled therein. The coil 1, whose scale contains a residual FeO after said water cooling, is uncoiled from a coiler 2, and is subjected to a cold rolling mill 4 for rolling with a 4W40% draft percentage; hereby, the scale layer is sufficiently crushed into pieces. A high pressure water is jetted from a jet nozzle 6 of a high pressure water jetter 5 so as to violently collide with the strip surface and remove the crushed scale. Or otherwise, instead of this high pressure water jetter, a brushing apparatus, etc., is employed to remove the scale. Thus descaled strip is coiled by a coiler 7, or is sent to a cold rolling mill 8, according to the necessity.

摘要： PURPOSE:To stably obtain a thin sheet of amorphous metal of uniform thickness by producing the thin sheet of amorphous metal while retreating a nozzle based on the thermal expansion of a rotary drum. CONSTITUTION:The gap up to the surface of a rotary drum 10 is measured with a gap sensor 26, and the measured signal is outputted to an operator 28, whilist the gap value up to the drum 10 before the start of production is outputted to the operator 28 by a commander 27. The difference thereof is operated by the operator 28, and this operated value corresponds to the rate delta of thermal expansion of the drum 10. This value delta is outputted to an adder 30, and a nozzle gap set value G0 is outputted from an indicator 29 as well. The value G0 and the rate delta are added in an adder 30, and a motor 25 is so controlled by way of a driving control circuit 31 that the gap coincides with the output of the adder 30. A screw 24 driven by the motor 25 revolves to vertically move a support plate 23, thereby adjusting the gap between the drum 10 and a tip nozzle 16.

摘要： PURPOSE:To manufacture a one-side hot dipped steel strip with superior characteristics by forming a film of a water glass-carbon powder composition as a hot dipping inhibitor on a side of a steel strip requiring no hot dipping and dipping the strip in a hot dipping both. CONSTITUTION:Powder of sootlike amorphous carbon is uniformly dispersed in a soln. prepared by moderately diluting a thick aqueous soln. of alkali silicate with water optionally in the presence of a surfactant. This composition as a hot dipping inhibitor is applied to a side of a steel strip requiring no hot dipping, dried, and vitrified by heat treatment to form a dense film. The strip is passed through a reducing furnace, where iron oxide on a side requiring hot dipping is activated by reduction, and the strip is dipped in a hot dipping bath to carry out one-side hot dipping. The inhibitor film on the side requiring no hot dipping is then removed with a brushing roll or the like.

摘要： PURPOSE:To prevent oscillation of a steel belt and to enable a reliable guiding and conveying thereof, by a method wherein a tension, which is directed toward the outside and in the direction of width, is applied, without mechanical contact, but by magnetic means for developing a magnetic field. CONSTITUTION:Magnetic means 14, 14 are located in proximity of both edges of a steel belt 12 conveyed continuously. Permanent magnets and electromagnets are used as the magnetic means. Magnetic poles 16 are supported by supporting members 18, and a gap G is detected by means of detecting means 20. Through the running of a motor 26, a screw rod 28 is turned to adjust the gap G. A steel belt 12 is conveyed in a stable position, and is prevented from moving in staggered manner.
