外刊报道,挪威研制成了一种称为“泰拉克”(Terac)的空冷电磁钢板矫平机,它能大大改善船厂矫正钢板变形和其他钢结构焊接的工作。该机器由高频变换机、感应加热头和与之相联的高频柔性电缆所组成。工作时电磁力将感应加热头紧吸在甲板或壁板上。感应加热头由压缩空气冷却。这种看起来像真空吸尘器的感应器在被吸的钢板内产生涡流,很快地将170×6mm的制板条形区域集中加热。感应加
External press reports, Norway has developed a called “Terac” air-cooled electromagnetic steel leveler, it can greatly improve the shipyard straightening plate deformation and other steel welding work. The machine consists of high-frequency conversion machine, induction heating head and the associated high-frequency flexible cable. Electromagnetic force at work will be induction heating head tightly sucked in the deck or wall. The induction heating head is cooled by compressed air. The inductor, which looks like a vacuum cleaner, generates eddy currents in the sucked steel plate and quickly heats the 170 x 6 mm plate strip area intensively. Induction plus
