本文首先將轉爐石、泥岩和處理後之廢液晶玻璃研磨成粉末,轉爐石添加量設定為25%和35%等兩種;助熔劑設定為3%、6%和9%等三種,發泡劑設定為0%、1%和2%等三種,其燒結溫度設定為950℃、1000℃及1020℃等三種,材料經混拌後壓製成坯體再燒製成紅磚,再進行抗壓、吸水率、掃描式電子顯微鏡等試驗,進而探討紅磚燒結產製技術及工程特性。
經試驗結果證實:
(1)在相同助熔劑(氧化鐵、小蘇打)用量由3%增加至9%,及發泡劑採用硼酸用量固定為0%、1%及2%使用量下,轉爐石添加量為25%,燒結溫度設定為950℃、1000℃及1020℃三種,當燒結溫度達1000℃時其抗壓強度及吸水率均符合3種磚之要求。
(2)在相同發泡劑(硼酸或碳酸鈉)固定為0%、1%、2%,助熔劑(氧化鐵、小蘇打) 使用3%、6%、9%下,轉爐石添加量為25%,燒結溫度設定為950℃、1000℃及1020℃三種,當燒結溫度達1000℃時其抗壓強度及吸水率均符合3種磚之要求。
(3)在相同發泡劑及助熔劑使用量下,抗壓強度隨著溫度的升高而增加,隨著轉爐石添加量增加而下降,轉爐石添加量以25%為最佳。
(4)發泡劑採用硼酸,助熔劑採用氧化鐵,抗壓強度隨著溫度的升高而增加,亦隨氧化鐵添加量、硼酸添加量增加而增加。
(5)隨著發泡劑或助熔劑添加量增加至3%時坯體內部呈熔融塊狀,並有小氣泡存在,坯體顆粒內部原子的動能變大,晶界移動,晶粒長大,造成氣孔減少,緻 密化程度提高。
(6)在相同轉爐石25%,發泡劑硼酸採用2%,助熔劑採用氧化鐵添加量由3%增加到9%,坯體內部呈熔融塊狀,晶粒長大,並有氣泡存在。

關鍵詞:轉爐石、抗壓、掃描式電子顯微鏡、助熔劑、發泡劑

Experimental results have proven that:
(1)At the same flux (iron oxide, sodium bicarbonate) the amount was increased from 3% to 9% and swell agent (boric acid) fixed at 0%, 1% and 2% usage , BOFS dosage is set to 25%, the sintering temperature is set at 950℃, 1000℃ and 1020℃, when the sintering temperature of 1000 ° C, the compressive strength and water absorption are requirements of the three kinds of brick.
(2) At the same swell agent(boric acid or sodium carbonate) fixed at 0%, 1% and 2% usage , flux (iron oxide, sodium bicarbonate) the amount is fixed at 3%, 6% and 9% usage , BOFS dosage is set to 25%, the sintering temperature is set at 950℃, 1000℃ and 1020℃, when the sintering temperature of 1000 ° C, the compressive strength and water absorption are requirements of the three kinds of brick.
(3)In the same usage amount of swell agent and flux, compressive strength increases with increasing temperature, and decreases with increasing BOFS dosage, BOFS dosage of 25% is the best.
(4)Swell agent is used boric acid, flux is used iron oxide, compressive strength increases with increasing temperature , iron oxide and boric acid addition amount.
(5)With the increased amount 3% of swell agent or flux, sintered body showed internal molten lumps, small bubbles exists and increases degree of densification.
(6)BOFS dosage is 25%, swell agent is used 2% boric acid, flux is used iron oxide which the amount was increased from 3% to 9%, sintered body showed internal molten lumps and small bubbles exists.
