Traditional tire vulcanization technology has notable drawbacks,for example,the heat transfer is uneven and uniformity of a tire is low.A new type of inner mould direct-pressure tire vulcanization technology is introduced.The new technology method can solve probloms in traditional tire vulcanization by utilizing the building drum to replace the curing bladder of the central mechanism and using electromagnetic-induction heating method to heat green tire cavity. This paper mainly illustrates the development process of the inner mould direct-pressure tire vulcanization technology equipment based on the current tire shaping press vulcanizer.

This paper introduces an electromagnetic induction heating method which is demonstrated to be able to bond carbon nanotubes and metal electrodes. Dielectrophoresis method is taken to realize the parallel directional assembly between carbon nanotubes and metal electrode, and then localized induction heating is adopted to bond them. This technique offers a convenient and reliable way in the practical applications of carbon nanotube interconnection. The bonding principle and process are introduced, and the experiment results are also discussed. The results show that the bonding interface exhibits good contact and electrical property.

Induction Heating System

In this work, the dimensions of a furnace for melting of ferrous alloys were determined. The furnace has an electromagnetic induction heating system. In addition, the parameters of electrical power supply such as frequency and power were calculated. A 5kg cast steel mass with a density of 7.81 kg / dm3 was proposed. This corresponds to a crucible volume of 0.641 dm3. The frequency was obtained from tables, which take into account the diameter of the crucible, and its value was 1 KHz. The energy consumption was determined with the heat required to bring the steel to the temperature of 1740 K, the energy losses through the walls, bottom and top of the crucible. This value was divided between the heating time (30 minutes) and resulted in a power of 4.5 KW. The development of the calculations shows that the induction heating is an efficient process and allows a fast melting of ferrous alloys.

Nickel-titanium shape memory alloy (NiTi-SMA) implants might allow modulating fracture healing, changing their stiffness through alteration of both elastic modulus and cross-sectional shape by employing the shape memory effect (SME). Hypotheses: a novel NiTi-SMA plate stabilizes tibia osteotomies in rabbits. After noninvasive electromagnetic induction heating the alloy exhibits the SME and the plate changes towards higher stiffness (inverse dynamization) resulting in increased fixation stiffness and equal or better bony healing. In 14 rabbits, 1.0 mm tibia osteotomies were fixed with our experimental plate. Animals were randomised for control or induction heating at three weeks postoperatively. Repetitive X-ray imaging and in vivo measurements of bending stiffness were performed. After sacrifice at 8 weeks, macroscopic evaluation,µCT, and post mortem bending tests of the tibiae were carried out. One death and one early implant dislocation occurred. Following electromagnetic induction heating, radiographic and macroscopic changes of the implant proved successful SME activation. All osteotomies healed. In the treatment group, bending stiffness increased over time. Differences between groups were not significant. In conclusion, we demonstrated successful healing of rabbit tibia osteotomies using our novel NiTi-SMA plate. We demonstrated shape-changing SME in-vivo through transcutaneous electromagnetic induction heating. Thus, future orthopaedic implants could be modified without additional surgery.
