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.

PURPOSE: An automatic operation planning system using a three-dimensional model and an operation planning method using the same are provided to facilitate spinal fixation by automatically generating the optimal diameter of a screw spike. CONSTITUTION: A three-dimensional model for an object to be inserted is extracted(S10). A candidate group for an insertion path of a screw spike is chosen using the three-dimensional model. Operation suitability is computed about the candidate group. The safety margin of the screw spike is computed(S40). A planned insertion path for the screw spike is determined based on the computed safety margin(S70).

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.

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.

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.

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: An apparatus for coating a roll plate is provided to prevent the damage of the apparatus due to a coating solution by preventing the scattering phenomenon toward the edge part of a coating roller in a coating process with respect to the surface of the roll plate. CONSTITUTION: An apparatus for coating a roll plate includes a storage chamber and a plurality of coating rollers(7). A coating solution, which is used for coating the surface of the roll plate, is stored in the storage chamber. The coating solution is applied to the external surface of the coating rollers. The coating rollers coat the surface of the roll plate. The wettability of the center part of a coating roller is different from that of the edge part of the coating roller.
