[Control of refractory dust in the continuous casting of steel].

Dusts from refractory material are indicated as determining steel plant work site pollutions. To reduce the danger from the dustiest operation--the demolition of coating--the A. examines the possibility of technical prevention based not on the individual protection, but on the use of lower content in free silica materials, on operative ways that underexpose the workers and on the aspiration at source of the produced dust.
