    摘要: With a powdered lubricant composition by the invention, in addition to the blending of one of anhydrous, pentahydrate or decahydrate salt in sodium borate and one of sodium or calcium salt of fat acid, mixing calcium or lithium carbonate as an auxiliary lubricant can prevent sodium borate (Na2B4O7), solidified as amorphous after a tube-making process, from moisture absorbance, drying and crystallization to thereby suppress the formation of Na2B4O7.5H2O on inside surfaces of finished-product tubes, thus enabling to circumvent occurrence of the white scales. Concurrently, they provide good diffusivity toward the working surface of workpiece, thus enabling to prolong a life of the mandrel bar and to widely be adopted as the most suitable powdered lubricant for manufacturing seamless tubes by Mandrel Mill rolling.

    摘要: According to an embodiment, a power transmitting device includes a power supply unit, a power transmitting coil, a first switch, a piezoelectric element, and a first switch controller. The power supply unit is configured to generate a transmission power by using power supplied to a power input terminal. Once the first switch is turned on, the first switch electrically connects an external power supply and the power input terminal until the first switch is turned off next time. The piezoelectric element is disposed at a position at which a weight of a placed power receiving device can be detected. The piezoelectric element is configured to generate a detection power according to the weight of the placed power receiving device. The first switch controller is configured to generate a starting power by the detection power and switches the first switch to on by using the starting power.
