Steel slag typically contains 5% to 9% of metallic iron and 14% to 20% of the iron-containing magnetic materials [3,4].
In order to recycle the iron-containing magnetic materials from steel slag, most steel companies disposal slag by crushing, grinding and magnetic separation process [5-8].
Chemical compositions of the experimental materials can be seen in Table 1.

Introduction: Solid Polymer electrolytes are materials of current interest due to their special mechanical properties, ease of fabrication in thin films of desirable sizes, electrochemical stability, volumetric stability and proper electrode-electrolyte contacts in different electrochemical devices [1].
Because each different material is a unique combination of atoms, no two compounds produce the exact same infrared spectrum.
Therefore, infrared spectroscopy can result in a positive identification (qualitative analysis) of every different kind of material.

Typical polishing pads are made of aluminum and hardened steel, although more elastic materials, such as synthetic rayon and synthetic chemical resistant pads, are used to make the polishing pads softer, smoother, and more suitable for surface polishing and leveling.
In 1997, Bulsara [4] studied the flash temperature of the polishing process and discovered the maximum and average interface flash temperatures of different materials and particle sizes.
Experiment equipment To test the validity of the theory, materials used for typical polishing devices were used.

(3) Cliffide Flower, maintenance-free after the earthquake (good function of recovery), application of new materials, and simple-reliable structure must be considered together in the seismic design of bearings, and they are the development directions of bearing design.
Materials are very important to bearings, and there is no time to delay for finding more powerful and more comprehensive materials.
