According to one embodiment of the present invention, a method of manufacturing a seismic-resistant steel bar comprises: a step of reheating a cast-piece in a temperature range of 1000-1250°C; a step of heat rolling the reheated cast-piece; and a step of cooling a steel bar formed by the heat rolling in a tempcore maintained at a recuperation temperature of 580-600°C wherein the cast-piece includes 0.29-0.31 wt% of carbon (C), 0.15-0.25 wt% of silicon (Si), 1.30-1.35 wt% of manganese (Mn), and the remaining consisting of iron (Fe) and other inevitable impurities. The manufactured steel bar has a yield power (YP) of 500-620 MPa; 12% or more of an elongation ratio (EL); and a yield ratio (YR) of 0.8 or less.

The present invention relates to a reinforcing bar and a manufacturing method for the same. The present invention is to provide the light reinforcing bar having high strength and high ductility by having an even Fe_3_AlC fine grain particle in base metal by dispersion reinforcement. According to an embodiment of the present invention, the manufacturing method for the same includes: a step of reheating a billet at the temperature of 1100-1200°C; a step of hot-rolling the reheated billet at a finish rolling temperature of Ac1-1000°C; a step of cooling the surface of hot-rolled steel at the temperature of Ms-100 to Ms (°C) as the steel hot-rolled passes through a tempcore; and a step of recuperating the cooled steel at the temperature of 500-600°C. The billet has alloy composition including 0.1-1.5 wt% of carbon (C), 0.05-1.0 wt% of silicone (Si), 0.5-16.0 wt% of manganese (Mn), 0-0.03 wt% (not including 0) of phosphorus (P), 0-0.03 wt% (not including 0) of sulfur (S), 0-9.0 wt% (not including ...

The present invention relates to an IoT-based traditional market fire spreading prevention system. More specifically, slave gas detectors are installed in each booth (store) of a traditional market, and if one of the detectors detects gas or organic compounds (VOC) generated from the ignition of an electric wire, a master fire predictor obtains a plurality of pieces of gas detection information through wireless communication and compares the information to a critical inclination value of gas concentration by gas type, and then, if the information exceeds the value, the predictor provides event analysis result information to each of the slave gas detectors so as to turn a fire hydrant on through a slave gas detector, which has detected the gas to conduct initial fire suppression and allow the other slave gas detectors to issue a fire alarm to prevent the fire from spreading.

An SLA 3D printer according to the present invention comprises: a plurality of shaping plates; a shaping plate moving means for controlling each of the shaping plates; a resin container containing the shaping plate and a photo-curable liquid resin; a light source for curing the liquid resin; and an optical path changing means for changing the optical path. When one shaping plate of the shaping plates is being moved by the shaping plate moving means, the optical path changing means changes the optical path so that light of the light source is scanned on another shaping plate that is not moving.
