REDUCTION SMELTING OF ANTIMONY CONCENTRATE

The formation of metallic antimony occurred without any decomposition in the course of the direct reduction of sodium metaantimonate. The concentrate reduction smelting carried out in presence of a refining flux provided to obtain rough antimony of low impurities content.

Measuring angles on HSS cutting bits

May 02, 2012The last two posts suggest that there are two ways of getting the angles on tool bits right. One is by construction: you use a fixture that has the correct angles built-in to hold the cutting tool at the correct angle. The other is cut and try, by continual measurement and refining, until your bit is spot on. Get price
