Abstract: The present disclosure discloses a substrate heat-treating apparatus including a process chamber in which a flat substrate to be heat treated is placed, the process chamber comprising a beam transmitting plate placed below the flat substrate and an infrared transmitting plate placed above the flat substrate; a beam irradiating module for irradiating a VCSEL beam having a single wavelength to a lower surface of the flat substrate through the beam transmitting plate; and an temperature measuring module configured to measure the laser beam reflected from the lower surface or an upper surface the flat substrate, thereby measuring the temperature of the flat substrate.

Abstract: Disclosed are: an enamel composition which has excellent cleaning functionality, and which, when used to form an enamel coating on a metal base material, ensures excellent thermal shock resistance and durability by suppressing the generation of defects caused by gas generation; a method for manufacturing same; and kitchenware using same. In addition, the enamel composition according to the present invention has excellent thermal shock resistance and durability due to having a component system in which glass-forming components and catalytic components are optimized.

Abstract: An enamel composition for a cooking appliance is prepared by a preparation method. The enamel composition includes glass frits, a siloxane-based compound, a silane-based compound, and mill addition. The mill addition includes one or more materials selected from a group comprised of SiO2, Al2O3, ZrO2, and TiO2, thereby suppressing defects such as chipping even when the enamel composition is used at high temperature, for pyrolysis of contaminants.

Abstract: The present disclosure relates to an enamel composition, a method for preparation thereof, and a cooking appliance using the same, which provide excellent cleaning performance, reduce a defect caused by carbon gases when an enamel coating is implemented on a base material made of cast iron, and provides excellent thermal shock resistance and durability. In the enamel composition according to the disclosure, components implementing glass and components having catalytic performance have an optimal component system, thereby ensuring excellent thermal shock resistance and durability. The enamel composition of the present disclosure has a component system that helps enamel cast iron as well as low carbon steel, thereby ensuring excellent cleaning performance, thermal shock resistance and durability. The enamel composition of the present disclosure is appropriate for a cooktop grate, a hob burner, and the like which directly contact a fire and are exposed to repetitive thermal shock.

Abstract: A coating composition, coating glass and a method for preparation thereof, and a cooking appliance including the coating class are described. The coating composition includes a coating material and a heat conductive oxide nano powder that is 5 to 10 wt % with respect to a weight of the coating material. The coating composition provides an excellent infrared reflective function, a high transmittance, and an excellent cleaning performance.
