A report is given the method for preparing the sample with stainless steel chips from lath (Kieseling) machine for spectrochemical analysis of stainless bloom. Each stainless steel chip was needed to be embedded some material to remove oil and scale from the surface with belt grinder. Lead and tin were most suitable materials for embedding the chips because no interfering elements for the analysis of stainless steel were contained in them. Procedure of the preparation of the sample was as follows;
Aluminum ring (diameter 25mm) was put into die of briquetting press and was filled with granule lead or tin. The stainless steel chip was cut into 24mm×20mm and was put on the lead or tin and then was pressed with 20 tons. The briquetting sample could be grinded and was suitable for spectrochemical analysis.
After the analysis, the stainless steel chip was easily removed from briquetting lead or tin by wrench both side of the sample with a pair of pinchers or pliers.
By this procedure, the analytical results were obtained within 6 minutes and good accuracy and reproducibility were obtained.
