English to Portuguese Tech/Engineering Mechanics / Mech Engineering

One key part, known as “spinner”, receives the glass against a wall referred to as “band” pierced with holes through which the glass passes under the effect of the centrifugal force in order to escape from all parts thereof in the form of molten filaments

The spinner is a fiberizing tool which is highly stressed thermally (heat shocks during startup and shutdown operations, and establishment, in stabilized use, of a temperature gradient along the part), mechanically (centrifugal force, erosion due to the passage of the glass) and chemically (oxidation and corrosion by the molten glass, and by the hot gases emerging from the burner around the spinner).
