1. Unless the context otherwise requires,

(a)  “crucible” means a pot made of refractory earth or made of metal lined with refractory materials, used to melt metals;

(b)  “mould and core oven” means a heating chamber made of brick, stone or metal and used to bake cores and sand moulds;

(c)  “foundry” means an industrial establishment where ores, metals and alloys are melted, purified or converted;

(d)  “cupola furnace” means a furnace composed of a vertical steel cylinder lined with refractory materials and topped with a stack to evacuate the gases from the combustion. The melting of pig iron mixed with coke and fluxes is activated by a current of compressed air. A few cupola furnaces are equipped with a water cooled system;

(e)  “electric arc furnace” means a fixed, rotary, or tiltable furnace to produce steel, iron or alloys. This furnace consists of a cylindrical or elliptical steel shell lined with refractory materials and provided in the top with openings for insertion of 2 or more electrodes. These electrodes are automatically raised or lowered to maintain proper arcing distance from the charge for melting heat energy from the arcs;

(f)  “crucible furnace” means a furnace built of refractory materials, provided in the top with melting holes for insertion of crucibles;

(g)  “induction furnace” means a furnace of a fixed or tiltable type, composed of a vertical steel cylinder normally lined with refractory materials. The induction furnace uses the transformer principle to melt the metal. A high voltage circuit is coupled to a low voltage circuit, these 2 circuits not being connected directly. The coupling is done by a magnetic field produced when the primary coil is energized;

(h)  “heating or thermal treatment furnace” means a reverberatory furnace of the recuperative, regenerative or other type used

i.  to reheat uniformally and gradually ingots, billets, sheet bars or forging rounds to predetermined temperatures, to make, by mechanical work, the forged or rolled steel products; or

ii.  to reheat the forged or rolled steel products to predetermined temperatures suitable for hardening, annealing, and tempering or other heat-treating processes;

(i)  “open-hearth furnace” means a horizontal stationary or tiltable furnace built of a steel frame lined with refractory materials, in which a current of burning gases from solid, liquid or gaseous fuel is passed over the top of the charge, and which is equipped with regenerators for the gases;

(j)  “furnace” means a structure or chamber, principally built of steel frame lined with refractory materials, for the purpose of melting ores or metals or subjecting them to the continuous action of intense heat;

(k)  “foundry operations” means all manual works carried out in a foundry for the purpose of melting or converting or refining metals and alloys in order to make ingots or castings. These operations include duties relative to pattern-making, moulding, pouring and trimming of castings;

(l)  “ladle” means a pot which, receiving the molten metal from the furnace, is used to carry it to the moulds into which it is to be poured.
