3 Definitions

In this standard use the following terms with respective definitions:

3.1 slag inclusion: a Defect in the form of a cavity, filled with slag.

3.2 contaminants: a Defect in the form of a metallic or non-metallic inclusions having a boundary surface with the base metal.

3.3 captivity: a defect in the form of a metal or oxide layer on the casting surface that occurs when not enough calm pouring of the metal.

3.4 the influx Defect in the form of leakage of metal to the surface of the base metal.

3.5 Bay: a Defect in the form of a metal protrusion on the pig, caused by ingress of liquid metal into the gaps on the connectors of the mold (shape).

3.6 inflation: a Defect in the form of blistering of the metal surface that occurs in pigs because of the presence of gas bubbles or non-metallic inclusions.

4 Stamps and technical requirements

4.1 casting Bronzes in pigs are manufactured in accordance with the requirements of this standard technological instruction, duly approved.

4.2 the Brand and the chemical composition of bronze must meet the requirements of table 1.

Table 1 — Chemical composition of bronze

4.3 the Mass of each pig shall not exceed 42 lbs. Shape and size of pigs established by the manufacturer.

4.4 On the surface of ingots shall not be sagging, bays, vaduthala, slag and foreign inclusions.
