Weigh 5 test portions under wind, convert to 0.00K1g, add water, and put the effective portion into a porcelain vortex. First low humidity carbonization, then put it into high temperature, At (575+25)℃, there is no black carbon. After cooling, add acid (1+12 (A.3.1) for a while, evaporate on the hot plate, then add hydrochloric acid (1+1)2 (A.3.1) and evaporate, and finally add concentrated hydrochloric acid (A.3.2) 2ml to evaporate. After cooling: dissolve part of the molten steel (A.3.4) in batches, transfer 250ml to a bottle, dilute to the scale. Use TwS1 type sodium concentration meter (A.2.2) to measure - first Ma4A.4.
