摘要： An alloying system for a galvanized steel sheet, the alloying system using an induction heating coil, wherein an impedance matching apparatus is provided between the induction heating coil and a high frequency power source. The impedance matching apparatus comprises a matching transformer having a plurality of intermediate contact points for arbitrarily selecting a turn ratio, and a switching device for alternative changeover of the intermediate contact point, whereby even when the load impedance of the steel sheet varies, maximum power source output is obtained, such that an appropriate heating temperature necessary for forming an alloy layer of the steel sheet can be supplied.

摘要： An improved method and a skid member for minimizing the temperature difference between a skid-contacting region and other regions in a hot material to be heated such as a slab or billet within a reheating furnace and a skid apparatus using the same. The skid member has at least one ventilation channel for restraining heat transfer toward a lower portion of the skid member for supporting or carrying the hot material in the reheating furnace and allowing passage of hot gas through the same to reduce the temperature difference between a contact region and a non-contact region of the hot material. The invention restrains heat transfer from the hot material to a skid coolant pipe and introduces hot gas within the reheating furnace into the skid member to compensate heat loss in an upper portion of the skid member, thereby preventing temperature drop in a contact region between a top face of the skid member and an underside of the hot material so that the rolling threading ability and quality of the hot material can be improved in subsequent processes.
摘要翻译：一种改进的方法和滑动构件，用于使待加热的热材料例如再加热炉内的板坯或坯料之间的滑动接触区域和其它区域之间的温度差最小化，以及使用其的滑动装置。滑动构件具有至少一个通风通道，用于限制向滑动构件的下部的传热，用于支撑或携带热再生炉中的热材料，并允许热气体通过其中，以降低接触区域之间的温度差和热材料的非接触区域。本发明抑制从热材料到滑动冷却剂管的热传递，并将再加热炉内的热气引入到防滑构件中，以补偿滑动构件上部的热损失，从而防止顶部之间的接触区域中的温度下降滑动构件的表面和热材料的下侧，使得随后的工艺中可以提高热材料的轧制能力和质量。
