6.3 quality Control of the surface subjected to every ingot.
7 control Methods
7.1 Sampling and sample preparation
7.1.1 the Chemical composition of the ingots of blister copper should be set on the basis of the measurement results combined samples of bottoms, made of shavings from the trial ingots.
7.1.2 Test bars should be selected directly during the filling of the mold by crossing jets of blister copper a special spoon-mold at the start, middle and end of filling each bucket or mixer with a capacity of 6 mor more.
Internal dimensions of spoon (spoon-mold): the bottom (bottom) — 90 x 90 mm; top — 110х110 mm; depth — 40 mm Permitted deviation of the specified size is not more than ±5 mm.
(Changed edition, Rev. N 1).
7.1.3 Extracted from a spoon (spoon-mold) trial ingot should be cleaned of grease and burrs, two opposite side surface to mark with a stigma with number of melt, cut or split diagonally into two parts so that each part had an intact seal, and the cut surface was smooth. Shavings from cutting the test bars should be included in the combined sample.
If the mass of the chips obtained from the cutting test bars will not be enough to perform the measurements and in the case of cutting of the ingots required by the mill to remove with a diagonal cut (cutoff) trial bars for more chips. The cutter should rotate at a speed that prevents oxidation of copper without the use of artificial cooling measures.
Allowed sampling chip lead methods of drilling or sawing.
The selection of chip drilling trial of the ingot is carried out through a drill bit with a diameter of not less than 15 mm at five points equally spaced on the upper surface of the ingot.
The selection of chips from a test ingot sawing is carried out by repeated sawing of the ingot along the diagonal. The number of cuts must be odd. The cuts are evenly placed on both sides of the ingot. The distance between the cuts should be no more than 5 mm. sawing is carried out using band saw machines.
