Incidence of cancer among ferrochromium and ferrosilicon workers: an extended observation period.
Results are presented of a cohort study on the incidence of cancers and crude death rates in ferrochromium and ferrosilicon workers. The whole cohort was observed from 1 January 1953 to 31 December 1985. Two sets of results are presented; one restricted to workers first employed before 1960 and one to workers first employed before 1965. The latter cohort consists of 1235 workers. The total mort...
متن کاملSlagging and Fouling Characteristics of HRSG for Ferrosilicon Electric Furnaces
The slagging and fouling characteristics of the heat recovery steam generator (HRSG) for ferrosilicon electric furnaces are discussed in this paper. Three ash samples were taken from the HRSG of a ferrosilicon furnace in Ningxia Province, China, which suffered from serious slagging and fouling. X-ray fluorescence (XRF), X-ray powder diffraction (XRD) and scanning electron microscope (SEM) were ...
متن کاملFuzzy Logic Control of Three Phase Submerged Arc Ferrosilicon Furnace
Research is made into the fuzzy control of electrode regulator systems of submerged electrical arc ferrosilicon furnace EAF. The equations of the electrode currents and furnace resistances are derived based on certain model for the submerged arc ferrosilicon furnace. This model takes into consideration the walls of furnace and the heat losses into external medium in addition to the heat transfe...
متن کاملRelease of Si from Silicon, a Ferrosilicon (FeSi) Alloy and a Synthetic Silicate Mineral in Simulated Biological Media
Unique quantitative bioaccessibility data has been generated, and the influence of surface/material and test media characteristics on the elemental release process were assessed for silicon containing materials in specific synthetic body fluids at certain time periods at a fixed loading. The metal release test protocol, elaborated by the KTH team, has previously been used for classification, ra...
متن کاملStudy of cancer incidence among 8530 male workers in eight Norwegian plants producing ferrosilicon and silicon metal.
OBJECTIVES To examine the association between cancer incidence, in particular incidence of lung cancer, and duration of work among employees in eight Norwegian plants producing ferrosilicon and silicon metal. METHODS Among men first employed during 1933-91 and with at least 6 months in these plants, the incident cases of cancer during 1953-91 were obtained from The Cancer Registry of Norway. ...
