    Abstract: Using Φ1.80mm steel wire drawn from Φ6.5mm steel wire was drawn to Φ1.80mm as raw material. Using cold three-rolling process, we got flat wire which size was 0.75mm x 3.17mm by cold three-pass rolling process. Researches shown that 60 steel wire has good plastic deformation ability during cold work processing. The tensile strength and micro-hardnes... Show More

    Abstract: The fire assay gravimetry is an old and classical method. It is one of most commonly used and most effective methods for the separation and analysis of precious metals due to strong representativeness, high accuracy and good stability. However, the fire assay gravimetry also has some disadvantages such as long analytical procedure and systemic lowe... Show More
