Abstract:
PURPOSE: A scale removing device is provided to reduce scale removal cost and to effectively remove scales with a simple device. CONSTITUTION: A scale removing device(100) comprises a first scale remover. The first scale removal removes scales formed in a first side surface of a strip and comprises a first frame(12) and a first removing block(14). The strip moves in a first direction to pass the first frame. The first removing block is protruded from the first frame and comes into contact with the scales when the strip moves in the first direction.
Abstract:
PURPOSE: A premelt pot is provided to precisely control the tapped amount of molten zinc by controlling the RPM(Revolutions Per Minute) of a screw, and to supply a preset tapped amount of the molten zinc in the premelt pot to a launder. CONSTITUTION: A premelt pot(1) comprises a launder(2), a pipe(3), and a screw(4), and receives molten zinc. The launder is connected to one side of the premelt pot. The pipe is installed in the molten zinc of the premelt pot and is connected to the launder. The pipe is vertically installed on the side wall of the premelt pot. The screw is embedded in the pipe, and is rotated to transfer the preset tapped amount of the molten zinc.
Abstract:
PURPOSE: A hot-rolled strip winder with an electromagnet is provided to tightly attach the end of a hot-rolled strip to a mandrel by applying magnetic force to the end of the hot-rolled strip. CONSTITUTION: A hot-rolled strip winder comprises a mandrel(2) and an electromagnet(3). The mandrel winds a hot-rolled strip(S). The electromagnet is arranged in the mandrel and applies magnetic force to the hot-rolled strip to attach the hot-rolled strip to the mandrel. The electromagnet is axially installed at the center of the mandrel.
Abstract:
PURPOSE: A premelt pot is provided to constantly maintain the surface level of molten zinc and to precisely control the tapped amount of the molten zinc. CONSTITUTION: A premelt pot(1) comprises a launder(2) and a level control part(3) and accommodates molten zinc. The launder is connected to one side of the premelt pot. The level control part is inputted in the molten zinc to apply pressure to the molten zinc so that the surface level of the molten zinc can be controlled.
Abstract:
PURPOSE: A welding check device is provided to measure a protruding weld position of an object by accurately positioning a welding check sensor on the object. CONSTITUTION: A welding check device(100) comprises a rotation supporting unit(10) and a welding check sensor(30). The rotation supporting unit supports an object(11) to rotate as being separated from the floor of a work place. The welding check sensor is installed via a sensor supporting unit(20) on the side of the rotation supporting unit and senses the outer surface of the object to check a weld position of the object.
Abstract:
PURPOSE: Tar and moisture removal apparatus and method for coke oven gas are provided to control the generation of condensed water during a cooling process of the coke oven gas. CONSTITUTION: A tar and moisture removal apparatus for coke oven gas includes a housing(100), a gas supply inlet(200), an air supply inlet(300), a cooling unit(400), a demister(500), a purification filter(600), a first vent(700), and a second vent(800). The housing includes a cooling space on the lower inside and a purification space on the upper inside. The gas supply inlet receives the coke oven gas from the outside. The air supply inlet receives air from the outside. The cooling unit is installed in the cooling space. The demister removes water drops contained in the coke oven gas. The purification filter filters foreign materials from steam contained in the coke oven gas.
Abstract:
PURPOSE: A device for detecting the rotation of a roller is provided to easily detect the rotation of a guide roller since a stator and a rotor detect the rotation of the guide roller generate when the guide roller rotates. CONSTITUTION: A device for detecting the rotation of a roller comprises a rotor(40), a stator and a current detecting unit. The rotor is close to the through hole of a roller, which passes through a rotary shaft. The rotor is fixed to the inside of the roller. The rotor is a permanent magnet. The stator is installed on the rotary shaft to face the rotor. The stator is wound on the iron core on the rotary shaft. The current detecting unit detects current from the stator or the rotator when the rotor rotates.
Abstract:
PURPOSE: An aluminum component for an internal combustion engine and a coating method thereof are provided to reduce frictional force and abrasion in an internal combustion engine by reduction in friction on the sliding portion of the internal combustion engine. CONSTITUTION: An aluminum component is manufactured to be applied in an internal combustion engine for a vehicle. The foreign material attached on the surface of aluminum components is removed. One electrolyte is selected. A hole, filled with lubricating oil, is formed on the surface of the aluminum components. The electrolyte is one selected among phosphoric acid, the sulfuric acid, and the oxalic acid electrolyte.
Abstract:
A superhydrophobic fluid transfer tube having superhydrophobic surface structures is provided to improve fluid transfer efficiency per unit area of the tube and to prevent corrosion of an inside surface of the tube by mounting solid material having the superhydrophobic surface structures in an inner wall surface of the tube. A superhydrophobic fluid transfer tube having superhydrophobic surface structures comprises a fluid guider(10) and solid material(20). The fluid guider guides fluid transfer. The solid material is mounted in a fluid contact surface of the fluid guider and has bending with a micrometer unit and a column with a diameter of a nanometer unit.
