我厂三座Φ3.3m×21m外燃式考贝热风炉建造有25年历史。大墙砖是附近冷水滩耐火材料厂七十年代耐热砼试验新产品(武钢院设计)质量好,保温砖较普通厚近一倍,因而一直未检修。近年来,陆续发现有两座热风炉蓄热室底部有漏风现象。其原因是历次修炉或改造时加高了地面;排水管路锈蚀漏水严重;地面不平而长期积水,致使热风炉长期坐立在半干半湿的基墩上,因而发生锈蚀。热风炉底部锈蚀的钢板很难焊接加固,给处
My factory three Φ3.3m × 21m external combustion test-bed furnace 25-year history. Large wall is the cold water near the beach refractories plant 70 years heat-resistant concrete test new products (WISCO hospital design) good quality, thermal insulation brick nearly twice as thick, which has not been overhaul. In recent years, one after another found that there are two hot air stove regenerator leakage at the bottom of the phenomenon. The reason is that the previous renovation or renovation of the furnace raised the ground; drainage rust corrosion serious; uneven ground and long-term water, resulting in long-standing stoves on the semi-wet base of the pier, resulting in corrosion. Stoves at the bottom of the corrosion of steel is difficult to weld reinforcement to give
