耐火材料工业是发展国民经济的重要行业之一,也是粉尘危害比较严重的一个部门。目前,全国有耐火材料厂903个,其中县级以上的214个(包括冶金系统重点耐火厂52个)。生产的主要品种有粘土砖,高铝砖、矽砖、镁质砖、白云石、焦油砖等。主要用于钢铁冶炼、建材、玻璃等行业。据统计,全国耐火企业现有职工12万人,接尘人数占60%。每年死于矽肺病的人数超过工伤事故死亡人数,不少企业矽肺病发病率呈上升的趋势。
Refractories industry is one of the important industries for the development of the national economy, but also a more serious damage to dust a department. At present, there are 903 refractories plants throughout the country, of which 214 are above the county level (including 52 key refractories in the metallurgical system). Production of the main varieties of clay brick, high alumina brick, silica bricks, magnesia brick, dolomite, tar brick. Mainly used in steel smelting, building materials, glass and other industries. According to statistics, there are 120,000 employees in refractory enterprises in the country, accounting for 60% of the total population. The number of deaths from silicosis each year exceeds the number of deaths from work-related accidents, and the incidence of silicosis in many enterprises is on the rise.
