BACKGROUND The Nordic Safety Climate Questionnaire-50 (NOSACQ-50) was developed by a team of Nordic occupational safety researchers based on safety climate and psychological theories. The aim of this study was to develop and validate the Persian version of NOSACQ-50 and assess the score of safety climate on a group of workers in a steel company in Iran. METHODS The Persian version of NOSACQ-5...

This paper considers the one-dimensional cutting stock problem with divisible items, which is a new problem in the cutting stock literature. The problem exists in steel industries. In the new problem, each item can be divided into smaller pieces, then they can be recombined again by welding. The objective is to minimize both the trim loss and the number of the welds. We present a mathematical m...

The purpose of this study was to identify and assess dust exposure in Electrical Arc Furnaces for steel manufacturing. The major concern of steel making processes is dust generation and accumulation. The scope of this research paper focuses on different ways to improve current controls and make recommendations. In order to achieve the purpose, various goals were developed to identify the extent...

The development of continuous casting to produce semi-finished products is now so far advanced that almost any grade of steel can be continuously cast, and in the most appropriate cross section for further shaping. High quality finished products can only be produced by using defect free slabs, blooms or billet. The removal of defects is either performed selectively by removing the specific defe...

Background: A high prevalence of noise-induced hearing loss (NIHL) is observed amongst employees in the steel manufacturing industry. Objective: To determine the prevalence of NIHL and current noise abatement techniques implemented at a steel manufacturing plant. Methods: Structured questionnaires were completed by permanent employees at a steel-manufacturing plant for the purpose of collecting...

The health status of workers in small companies has been noted to be relatively poor, but no actual comparisons of groups of variously sized companies within the same region based on the same methodology have ever been conducted. We undertook this study to clarify differences in health status according to company size. The subjects comprised workers of a Japanese steel company and various subco...

In a time when modern production has become exposed to strict market demands, in terms of increasing quality, shortening the processing time and reducing the cost of the final product, laser processing has become a necessity in almost all manufacturing industries. Each laser manufacturer, including the Swiss company Bystronic, gives recommended cutting parameters for certain types of materials....
