2O
3）低於10%重量百分比，再於該灌模步驟中，將前述該鎂質澆注料與水依比例混合並灌注入模具中進行成型，最後於該成型步驟進行脫模與乾燥，以得到鎂質耐火止擋件，如此不僅大幅提升該鎂質耐火止擋件的承受力與抗侵蝕性能，同時該鎂質耐火止擋件得以有效吸附鋁質，更加提升鋼液清淨度。
Description
本發明是有關於一種製造方法，特別是一種用於分鋼槽之鎂質耐火止擋件的製造方法。
查，分鋼槽是鋼液連鑄工藝中一個不可缺少的重要容器，其主要用於穩定鋼液流量，以及達到分流和保證鋼液連續澆鑄不斷流的作用，該分鋼槽內通常設有耐火止擋件，如擋渣牆等，其用於均勻鋼液溫度，改變鋼液流向，並且有利於夾雜物上浮、碰撞、聚集，進而減少夾雜物捲入鋼胚，藉以提升鋼液清淨度，由於該耐火止擋件需要長期浸泡在高溫鋼液中，其必須要有良好的承受力與抗侵蝕性能。
目前常見的耐火止擋件係以鋁矽質為主，然，實際使用後發現，前述該鋁矽質止擋件容易被該分鋼槽的渣侵蝕，使得該鋁矽質止擋件於作業過程中容易形成夾雜物捲入鋼胚中，致使該鋁矽質止擋件對鋼液造成汙染，以及導致鋼液清淨度不佳之缺失，當該鋁矽質止擋件直接承受高溫鋼液的沖刷及強烈的熱應力時，該鋁矽質止擋件更可能產生變形、穿孔、裂開或垮塌等現象，實有待改善。
因此，本發明之目的，是在提供一種用於分鋼槽之鎂質耐火止擋件的製造方法，其大幅提升鎂質耐火止擋件的承受力與抗侵蝕性能，並且該鎂質耐火止擋件可以有效吸附鋁質，藉以提升鋼液清淨度。
於是，本發明用於分鋼槽之鎂質耐火止擋件的製造方法，其依序包含有準備、混拌、灌模及成型等步驟；其中，該準備步驟中，備具有重燒鎂砂、橄欖砂、鍵結劑、解膠劑，以及抗水化劑，接著於該混拌步驟中，將30~50%重量百分比之該重燒鎂砂、40~60%重量百分比之該橄欖砂、5~10%重量百分比之該鍵結劑、1%重量百分比以下之該解膠劑，以及1%重量百分比以下之該抗水化劑均勻混合得到鎂質澆注料，且前述該鎂質澆注料所含之三氧化二鋁（Al
2O
3）低於10%重量百分比，再於該灌模步驟中，備具有一模具，以將前述該鎂質澆注料與5~10%重量百分比的水灌注入該模具中進行成型，最後於該成型步驟中，進行脫模與乾燥後，即可得到鎂質耐火止擋件，是以，透過該抗水化劑包覆粒子，以及利用該解膠劑於混拌過程中有效將微粉打散，同時混拌過程得以使微小粒子充填於孔隙中，進而減少該鎂質耐火止擋件的表面孔隙，不僅大大提升該鎂質耐火止擋件的承受力與抗侵蝕性能，且該該鎂質耐火止擋件於作業過程中得以有效吸附鋁質，進而提升鋼液清淨度。
有關本發明之前述及其他技術內容、特點與功效，在以下配合參考圖式之較佳實施例的詳細說明中，將可清楚的明白。
參閱圖1所示，本發明一種用於分鋼槽之鎂質耐火止擋件的製造方法3包含有一準備步驟31，一混拌步驟32，一灌模步驟33，以及一成型步驟34；其中，該準備步驟31中備具有重燒鎂砂、橄欖砂、鍵結劑、解膠劑，以及抗水化劑，接著於該混拌步驟32中，將30~50%重量百分比之該重燒鎂砂、40~60%重量百分比之該橄欖砂、5~10%重量百分比之該鍵結劑、1%重量百分比以下之該解膠劑，以及1%重量百分比以下之該抗水化劑均勻混合得到100%重量百分比之鎂質澆注料，且該鎂質澆注料所含之三氧化二鋁（Al
2O
3）低於10%重量百分比，而前述該重燒鎂較佳以49%重量百分比為之，該橄欖砂較佳以45%重量百分比為之，該鍵結劑較佳以5%重量百分比為之，使得該鎂質澆注料的化學組成比例為氧化鎂（MgO）45~75%、二氧化矽（SiO
2）25~35%、三氧化二鋁（Al
2O
3）＜8%、三氧化二鐵（Fe
2O
3）＜5%及氧化鈣（CaO）≦1.5%。
仍續前述，於該灌模步驟33中，備具有一模具，而該模具的形狀可依據欲成型的止擋件形狀進行調整，接著將該混拌步驟32中所得到的該鎂質澆注料與5~10%重量百分比的水混合並灌注入該模具中，而前述加水量較佳以6.2%為之，使得該鎂質澆注料與水混合成型，最後於該成型步驟34中，針對前述該模具進行脫模，以便將該模具移除後得到鎂質耐火止擋件，而該鎂質耐火止擋件可為擋牆、流鋼嘴或四角磚等，需要設於該分鋼槽並與鋼液接觸之配件，待前述該鎂質耐火止擋件乾燥後，即可安裝於分鋼槽內使用，故，本發明藉由該解膠劑於混拌過程中有效將微粉打散，以及藉由該抗水化劑完整包覆粒子，同時混拌過程得以使得微小粒子充填於孔隙中，進而減少該鎂質耐火止擋件成型後的表面孔隙，使得該鎂質耐火止擋件的抗侵蝕性能得以大幅提升，此外，該鎂質耐火止擋件於乾燥後不會有裂痕，並且脫模順利，施工性與強度良好，再者，本發明經測試評估與預鑄灌注成型，可將該鎂質耐火止擋件進行量化生產，更加提升市場競爭力，同時該鎂質耐火止擋件完成後即可進行吊掛安裝，並且進行使用，使用狀況亦非常良好。
該鎂質耐火止擋件於完成後進行折斷測試（M.O.R）與抗壓測試（C.C.S），結果顯示折斷測試＞7.0 N/mm
2，且抗壓測試＞30.0 N/mm
2，亦即該鎂質耐火止擋件於初期強度高。
該鎂質耐火止擋件於進行坩堝測試後，結果顯示其侵蝕率為2.1%，以及滲透率為8.9%，前述結果均優於習知鋁矽質耐火止擋件的坩堝測試結果（侵蝕率18.9%，滲透率16.1%），代表該鎂質耐火止擋件具有較佳的抗侵蝕與抗滲透性能。
而水化測試中，將該鎂質耐火止擋件完全浸入水中，並於加蓋後以80℃恆溫置放240小時，結果顯示該鎂質耐火止擋件的重量增加率為2.3%，折斷測試增加3.7%，抗壓測試增加16.4%，且該鎂質耐火止擋件於水化測試後無裂紋，亦即該鎂質耐火止擋件具有良好的抗水化性能，並且非常穩定，另，該鎂質耐火止擋件以110℃經24小時乾燥完成後，其存放於室溫下40天的強度無明顯變化，測試結果如下表：
| 折斷測試（M.O.R） （N/mm 2） | 抗壓測試（C.C.S） （N/mm 2） | |
| 1天 | 7.3 | 34.9 |
| 10天 | 7.1 | 36.9 |
| 20天 | 6.7 | 34.8 |
| 30天 | 7.4 | 35.5 |
| 40天 | 7.5 | 35.7 |
