一、氧***上部的氧管彎道或變徑管由于流速大，局部阻力損失大，如管內有渣或脫脂不干凈時，容易誘發(fā)高純、高壓、高速氧氣燃爆。我們在方矩管生產(chǎn)中，應該通過改善設計、防止急彎、減慢流速、定期吹管、清掃過濾器、完善脫脂等手段來避免事故的發(fā)生。 </p> <p> 二、鐵、鋼、渣液的溫度很高，熱輻射很強，又易于噴濺，加上設備及環(huán)境的溫度很高，極易發(fā)生灼傷事故。所以我們要定期檢查、檢修煉鋼爐、鋼水罐、鐵水罐、混鐵爐等設備。同時注意改善安全技術規(guī)程并嚴格執(zhí)行，搞好個人防護，容易漏氣的法蘭、閥門要定期更換。 </p> <p> 三、因操作失誤造成氧***回水不通，氧***積水在熔池高溫中汽化，阻止高壓水進入。當氧***內的蒸氣壓力高于***壁強度極限時變發(fā)生。處理此類問題時應該更加謹慎，避免操作失誤。 </p> <p> 四、方矩管生產(chǎn)中應考慮煉鋼廠房的結構能夠承受高溫輻射，具有足夠的強度和剛度，能承受載荷和碰撞而不會變形。還要有寬敞的作業(yè)環(huán)境，通風采光良好，有利于散熱和排放煙氣，要充分考慮人員作業(yè)時的安全要求。 </p> <p> <br /> </p><p style="text-indent:25px">貴陽金順泰物資有限公司推薦:目前，我國國內生產(chǎn)的方矩鋼管產(chǎn)品較少，特別是作為高層或大跨度建筑的柱子，壁厚仍達不到使用要求，即便是寶鋼鋼鐵工藝研究所生產(chǎn)的方矩鋼管500mmx500mm，壁厚也只能達到19mm，因而廣州新白云機場的候機樓仍采用進口的方坯管。我國在建筑上應用較多的仍是箱形梁.其由四塊厚板焊接制成，壁厚要求也較高，如通常要求壁厚要達到20mm-60mm，甚至80mm、100mm等。2008年奧運會的主場館“”的箱形梁、柱，厚度一般都為50mm、60mm或80mm，甚至超過100mm。如果一部分能用方矩鋼管代替，將帶來的技術和經(jīng)濟效果國外一些生產(chǎn)企業(yè)由于采用特殊的生產(chǎn)工藝，已能夠生產(chǎn)大壁厚的方矩鋼管，這種方矩鋼管與箱形梁相比，可以減少焊接工作量，還能減少因焊接帶來的環(huán)境污染，同時鋼材如抗銹等性能也更有優(yōu)勢，表面也更為美觀。質優(yōu)價廉的方管方矩管焊管都在這里生產(chǎn)呢,質量過硬,價格合理。</p><div
