烧结矿抗压及跌落强度试验研究

Experimental Study on Compression and Drop Strength of Sinter

烧结矿制备及冷却是钢铁行业的重要工艺过程，烧结矿抗压和高位跌落强度是影响烧结矿成品率的重要参数。以烧结矿为试验样品，获取了烧结矿抗压和跌落强度。研究结果表明，对于试验样品烧结矿来说，20～30mm粒度烧结矿平均抗压强度为5．02MPa；500～700℃高温烧结矿2m高位跌落产生的10mm以下粒度的烧结矿最高增加2．70％，5mm以下粒度的烧结矿最高增加1．11％。

Sintering and cooling of sinter are important processes in steel industry. Compression strength and drop strength of sinter are important parameters that influence the rate of finished products of sinter. With sinter of a steel plant as experimental sample, the compression strength and drop strength of sinter was obtained. The results show that, for sinter sample with granularity between 20mm and 30mm, average compression strength is 5.02MPa; when sinter with temperature between 500~C and 700~C drops from 2m height to ground, sinter whose granularity is lower than 10 mm increases by 2.70 %, while sinter whose granularity is lower than 5 mm increases by 1.11 %.
