Abstract: The present invention relates to a container security apparatus which is easily attachable/detachable to/from both opening/closing bars of a container to sense whether the container is opened/closed and transmit the sensed information on whether the container is opened/closed to a remote location, to thereby check whether the container is sealed or not on a real time basis and thus safely transport the container, and to thereby check the current position of the container in transit and check whether or not the container has deviated from a predetermined path on a real time basis.

Abstract: A method of inoculating magnesium (Mg) on compacted graphite iron (CGI) comprises: providing a partition having a predetermined height on the bottom of a ladle so as to divide the interior of the ladle into a first space and a second space; laminating an Mg inoculant and a cover in order in the second space; and tapping liquid CGI cast iron onto the first space, whereby the Mg inoculant becomes in contact with the liquid CGI iron after the liquid CGI tapped onto the first space goes over the partition toward the second space and after the cover is melted by the liquid CGI. According to the method, the deviation of density of Mg is minimized, and a secondary inoculating process can thus be omitted.

Abstract: A method of inoculating magnesium (Mg) on compacted graphite iron (CGI) comprises: providing a partition having a predetermined height on the bottom of a radle so as to divide the interior of the radle into a first space and a second space; laminating an Mg inoculant and a cover in order in the second space; and tapping liquid CGI cast iron onto the first space, whereby the Mg inoculant becomes in contact with the liquid CGI iron after the liquid CGI tapped onto the first space goes over the partition toward the second space and after the cover is melted by the liquid CGI.

Abstract: A method for manufacturing a cylinder head system for a vehicle includes manufacturing a first main mold to integrally form an exhaust manifold for discharging exhaust gas from a cylinder and a first water jacket for cooling the exhaust manifold, manufacturing a second main mold to form a second water jacket for cooling a cylinder block, and connecting the first main mold to the second main mold. The mold includes a first main mold having a plurality of exhaust manifold molds and a first water jacket mold, each exhaust manifold mold being configured to form a respective exhaust manifold, and the first water jacket mold being configured to form a first water jacket for cooling the exhaust manifolds, a second main mold having a second water jacket mold, the second water jacket mold being configured to form a second water jacket for cooling a cylinder block, and the second main mold being configured to be assembled with the first main mold.

Abstract: Provided are a container security device, a container security system, and a security management method which efficiently check opening/closing of a container door and an opening/closing record of the container door and process seal information, cargo state information, base passing information, and location tracking information in real-time from a gate-out process from a shipper (POA) to a gate-in process to a consignee (POD). The container security system includes the container security device which includes a first communication means for providing container seal information through multi-channel communication; and a second communication means for providing information about container transportation and storage in real-time.
