| Resumen |
Under identical conditions, 3 different wires differed markedly in the amount of dust that they generated: averages ranged from 2.8 to 8.0g/min, or 14-40g dust/kg wire. The aerosol from low-alloy wire was largely iron oxide, with about 3% manganese oxide, whereas wire containing 23.6% chromium and 13.47% nickel gave aerosols containing similar proportions of chromium (mainly trivalent) and nickel oxides. Keeping amounts of airborne metals down to permissible levels requires exhaust ventilation at a rate of 7000m3 of air per kilogram of wire consumed, in the case of low-alloy wire, and 22,000m3/kg in the case of high-alloy wire. |
