Herein, guide rods(114) are installed on a body(110) for containing a moving stand(160). The moving stand moves along the guide rods for guiding wires such as a coil winding around a core material. Moreover, a detecting instrument(180) is installed on the body for detecting the moving stand. And, a cutter(190) is installed at one end of the body for cutting a coil spring for a desired length. A control box(200) is installed on one side of the body for controlling the movements of each instrument.

Title: Magnesia-alumina-iron oxide-zirconia refractory composition
Inventor: JUN WOONG
IPC: C04B35/106
Filed: 1998-12-19
Abstract: PURPOSE: A magnesia-alumina-iron oxide-zirconia refractory composition is provided, which is improved in heat-impact resistance and corrosion resistance. CONSTITUTION: A magnesia-alumina-iron oxide-zirconia refractory composition comprises 60-95 wt% of MgO; 3-20 wt% of Al2O3; 1-20 wt% of Fe2O3; and 1-20 wt% of ZrO2. This refractory composition can be used stably and substituted for MgO-Cr2O3 refractory causing environmental pollution.
Patent KR-20000041031-A (KR)
Title: Method for cooling stainless annealing plate and peeling scale
Inventor: JIN WON
IPC: C23G1/00
Filed: 1998-12-21
Abstract: PURPOSE: A method is provided to produce a stainless hot rolled plate having excellent surface quality by increasing ablating efficiency and acid cleaning efficiency and to save energy and make a process simple by cooling and ablating the plate in a scale breaker roll at the same time. CONSTITUTION: A scale breaker roll generates an initial vertical crack on the surface scale layer of an annealing plate. The annealing plate forming the vertical crack is cooled by an aqueous NaCl solution injector and at the same time, generates a horizontal crack on the scale and bulk material surface of the annealing plate. High pressure solution is injected into the annealing plate forming the horizontal crack by a high pressure water descaler to separate the scale layer from the plate and to clean NaCl aqueous solution.
