中小型铸造一般都设有无芯或有芯工频电炉,为了安全可靠,防止发生意外事故,必须注意以下几点:①筑炉或使用工频炉前,首先检查炉体电缆和各处紧固螺栓、螺母及炉体倾翻系统是否正常和安全。如果发现异常现象应及时报告、处理,切勿盲目蛮干使用,以免造成触电和炉体倾斜等事故。②筑炉时,应仔细认真,炉料切勿混有杂铁、碎玻璃、破布等杂物,以防筑炉时伤人和炉内衬出现漏铁。③炉子筑好后,严格检查水、电、液压等系统是否正常,确认无误后方可送电,进行烘炉。烘炉时先送水后送电,停炉时先停电后停水,并且保证停电后通水24h以上方可停水。烘炉时必须按烤炉曲线进行,并勤观察水压和水温及电流的波动情况,水压不足或出水温度过高报警时,要立即报告,进行检查,并采取切实可靠的措施,以防线圈被烧坏,出现
Small and medium-sized castings are generally equipped with coreless or core frequency electric furnace, in order to be safe and reliable, to prevent accidents, we must note the following points: ① furnace or use frequency furnace before, first check the furnace cables and tight everywhere Bolt, nut and furnace tipping system is normal and safe. If you find anomalies should be promptly reported, handled, do not blindly use it to avoid accidents such as electric shock and furnace tilt. ② When building a furnace, you should be careful and careful not to mix the charge with broken iron, broken glass, rags and other debris to prevent the wounding of the furnace and the leakage of the furnace lining. ③ After the furnace is built, strictly check the water, electricity, hydraulic systems are normal, confirm the correct before sending, for baking. When the oven first send water after the power, stop when the first power cut water, and to ensure that water after the power 24 hours before stopping. Ovens must be oven curve, and observe the pressure and water temperature and current fluctuations, insufficient water pressure or water temperature alarm is too high, to immediately report, check and take practical and reliable measures to prevent the line Circle was burned out, appeared
