生产实际中经常会遇到冲天炉在熔化过程中,遇突然停电。造型线出故障铸型过不来,造型机出故障无铸型浇注或炉后上料机构出问题等原因被迫停风的现象。采取保温处理措施后,即使停风1h以上也能照常开炉生产。 过去我们厂5t/h冲天炉在开炉初期停风不到半小时就被迫拉炉,不是出铁眼打不开,就是铁液过桥堵塞。开炉中期停风也只能维持半小时左右,时间再长就结炉,影响生产正常进行。为此,要分析研究冲天炉停风后的保温措施。 根据冲天炉内燃烧反应原理,由于停风后炉内空气稀簿形成负压,外界空气顺鼓风机风管进入炉
Production often encounter cupola in the melting process, in the event of a power outage. Molding line failure Casting too much, molding machine failure No mold casting or furnace feeding mechanism problems forced to stop the phenomenon of wind. Insulation measures taken to take, even if the wind stopped more than 1h can be opened as usual production. In the past our plant 5t / h cupola in the early blast furnace wind stopped less than half an hour was forced to pull the furnace, not a tapping eye can not open, that is, the iron bridge plugged. Open medium-term wind stopped only half an hour or so, longer time to stop furnace, affecting the normal production. To this end, we must analyze and study the cupola wind insulation measures. According to the cupola combustion reaction principle, as the air after the wind stopped blowing thin book to form a negative pressure, the air outside the blower duct into the furnace
