Abstract    In order to obtain the bulk brick like samples, the mixture of steel slag, and sintering aid additive (like dolomite, glass, perlite, borax and phosphate sodium) were sintered at 1100°C for 2 minute. The flat and bloated surface appearances were obtained. The bulk densities of final sintered composites were from 1.3 to 2.41 g/cm3 and total porosities were from 15 to 40%. The bending strengths varied from 5.5 to 15.9 Mpa.

 

Keywords    slag, sintering, dolomite

 

چکیده    به منظور به دست آوردن نمونه های بالک آجر مانند ، مخلوطی از سرباره فولاد و افزودنی های سینترینگ مثل دولومیت و شیشه و پرلیت و بوراکس ..در دمای 1100 درجه سانتی گراد به مدت 2 دقیقه سینتر شدند و قطعات با سطح صاف به دست آمد دانسیته قطعات بالک سینتر شده از 1/3 تا 2/41 گرم بر سانتی متر مکعب تغییر کرد و تخلخل کل از 15 تا 40% حجمی تغییر کرد . محدوده استحکام خمشی نیز از 5/5 تا 15/9 مگا پاسکال بود.
