Abstract:
A wiping device which blows a wiping gas toward a steel sheet from a pair of wiping nozzles disposed on both sides of the steel sheet so as to face sheet surfaces of the steel sheet, wherein the steel sheet is interposed between the pair of wiping nozzles and is pulled from a hot dip coating bath, the device includes a suctioning tube, wherein: the suctioning tube is disposed on both sides in a width direction of a section of the steel sheet, the section being positioned between the pair of wiping nozzles, so that the suctioning tube is in parallel to the steel sheet; the suctioning tube has a suctioning port that suctions an air; the suctioning port is disposed to face a side end surface of the steel sheet; a cross-sectional shape of the suctioning tube has the largest dimension thereof along a pulling direction of the steel sheet.
Abstract:
Provided is a steel strip stabilizing apparatus which allows shape correction and vibration suppression in a steel strip, particularly, plated steel strip, in a non-contact manner. The steel strip stabilizing apparatus includes an apparatus support body disposed on at least one side of a traveling steel strip and a steel strip stabilizing unit comprising a magnetic field generating pole disposed on the apparatus support body to face the steel strip and a pole expansion part configured to provide steel strip attraction force to a steel strip-side end of the magnetic field generating pole so as to allow shape correction or vibration suppression in the steel strip. The present invention increases the (electro)magnetic attraction force on the plated steel strip that passes through a plating bath, and thereby effectively ensures shape (curvature) correction or vibration suppression (damping) in the plated steel strip and prevents plating variations in the steel strip, and ultimately makes it possible to improve the quality of the plating of the steel strip.
Abstract:
The invention particularly relates to a method for the continuous deposition of a coating on strip-type substrate, in which the thickness of the coating depends on the condition of various actuators. The method of the invention includes a first preliminary phase that includes developing a pre-setting model, a second preliminary phase that includes developing an adjustment model, an intermediate pre-setting step (16) during which the actuators are set statically, a step of measuring the thickness of the coating (21), and an adjustment step (20) during which the actuators are dynamically controlled by a predictive control based on the adjustment model in order to reduce any potential difference between the coating measured thickness and a target value of said thickness.
Abstract:
A substantially uniformly coated substrate that may be either metallic or ceramic in nature as well as a process for preparing such coated substrate. The substantially uniformly coated substrate typically comprises a plurality of outlets; a plurality of substrate walls; and a plurality of channels defined by the substrate walls, said channels extending directly or indirectly from at least one outlet; and wherein there are a plurality of openings and/or corrugations and/or tabs in the substrate walls that communicate between adjacent channels, said substrate containing at least one substantially uniform layer of a coating material that may be a non-sorbent, non-catalytic material; a sorbent, non-catalytic material; a catalytic material or a mixture of two or more of the foregoing materials. The process for preparing such coated substrate involves immersing the substrate in a slurry of the desired material or materials, centrifuging the substrate so as to thereby distribute the material or materials as a substantially uniform layer on the substrate and remove any material or materials in excess of that desired to be present on the substrate, and thereafter drying and calcining the coated substrate.
Abstract:
Beschrieben ist ein Verfahren zur Eliminierung von an der Oberfläche eines Bauteils (1) lose haftenden oder hochstehenden Partikeln, die aus dem die Oberfläche des Bauteils (1) bildenden Metall, insbesondere Zinn oder einer Zinnlegierung, bestehen, bei welchem die Oberfläche des Bauteils (1) in einer Schutzgasatmosphäre (4) auf eine Prozeßtemperatur erwärmt wird, die gleich der Schmelztemperatur des die Oberfläche bildenden Metalls oder geringfügig niedriger als diese ist.
