Induction heating is advantageously used in the industry to (pre)heat workpieces from ferromagnetic metallic materials. However, its application for heating of paramagnetic workpieces is still a challenge. The presented study focuses on design and optimization of induction heating for a pre-sintered WNiCo tungsten heavy alloy billet intended to be subjected to plastic deformation via warm rotary swaging. Firstly, induction heating to the initial deformation temperature of 900 °C is simulated via two different computational software based on the finite element method (FEM) in order to perform the best possible optimization of the heating process. Secondly, experimental induction heating is performed, prior to subsequent warm rotary swaging, to verify the designed process. Comparison of the final billet temperatures and their developments acquired via simulation and experiment exhibited satisfactory correlation. The study is supplemented with structure observations documenting the required heating through the WNiCo billet; the swaged structure exhibited deformed tungsten agglomerates, as well as high quality oxidation-free surface.

感应加热在工业中有利地用于从铁磁金属材料中（预）加热工件。然而，将其用于加热顺磁性工件仍然是一个挑战。提出的研究重点在于预烧结的WNiCo钨重合金坯的感应加热的设计和优化，该预烧结坯将通过热旋转型锻进行塑性变形。首先，基于有限元方法（FEM），通过两个不同的计算软件模拟了感应加热到900°C的初始变形温度，以便对加热过程进行最佳的优化。其次，在随后的热旋转型锻之前，先进行实验感应加热，以验证设计的过程。最终坯料温度的比较及其通过模拟和实验获得的发展表现出令人满意的相关性。该研究还补充了结构观测资料，记录了通过WNiCo钢坯所需的加热；模锻的结构表现出变形的钨附聚物，以及高质量的无氧化表面。
