怎样延长中频电炉的使用寿命
[来源:www.zhongpinshebei.com] [作者:aywl] [日期:17-02-08]
首先,中频电炉在初次及日后的使用中,均需在炉体中打炉衬和对其进行烧结。炉衬根据原料和熔炼需要的不同分为酸性和碱性炉衬,我厂使用的是酸性炉衬。打炉衬,就是用石英砂等材料,沿炉体内壁做一保护层隔离熔炼料与炉体内的感应线圈,保护感应线圈。打炉衬时应注意,用力均匀打结实,一次打完,一次成型。炉衬打好后需经长时间低温烘烤,使之凝结成-个坚固的整体,且具有相当强度,能经受熔液搅拌和加料冲击。烧结时,应遵循空炉低功率慢升温的方法,连续烘烤 36小时以上,使之充分凝结固化。炉衬打结的好坏,是保证中频电炉的使用寿命和安全的重要前提。 First, intermediate frequency electric furnace in the initial and subsequent use, must be in the furnace lining and to sintering. Lining according to different raw materials and smelting need divided into acid and alkaline lining, our factory is using acid lining. Lining, is to use the material such as quartz sand, do one protective isolation melting along the furnace lining materials and the induction coil inside the furnace body, protect the induction coil. Lining should be paid attention to when, strength strong, a play, a molding. Lining play need to the long time after low temperature bake, condenses into - a strong overall, and considerable strength and can withstand liquid mixing and loading shock. Sintering, low power should follow the empty furnace slow heating, the method of baking more than 36 hours in a row, make sufficient condensation curing. The stand or fall of lining knot, intermediate frequency electric furnace is the service life and safety of important premise.   炉衬打结好后,如何正确、合理操作是延长中频电炉使用寿命和保证人生安全的关键。-般情况下,操作使用中频电炉前要先检查,水冷却系统水流是否通畅,冷却水水压、水温是否正常,是否有漏水现象,液压系统是否能正常工作。操作中要做到,小心谨慎不乱摸乱碰,一人操作,一人监护,并且严禁闲杂人员进入机房,防止触电。熔炼过程中要使用干燥的熔料,并做到轻放料,勤加料,当炉内熔料熔化达到需要时应及时倒出,避免高温增加炉衬损耗;勤观察,当发现炉体外侧有发红现象,这就是要漏炉的先兆,应及时采取关停中频电源,倒出炉内熔料等措施,避免漏炉事故的发生。使用中还应注意,当发现炉衬变得很薄,不能继续使用时,应砸掉旧炉衬重做新炉衬,防止漏炉事故发生。 Lining knot good after, how to correctly, reasonable operation is extending the service life of the intermediate frequency electric furnace, and the key to ensure life safety. - a case, the operation to check before using the intermediate frequency electric furnace, water cooling system, water flow is obstructed, cooling water pressure, water temperature is normal, whether there is leakage phenomenon, the hydraulic system can work normally. To do the operation, be careful not to touch touch, one operator, one person's care, and it is forbidden to sundry to enter the room, prevent to get an electric shock. To use dry in the process of smelting, melting and feeding, often charging, when molten material melt in the furnace to achieve required shall be poured out in time, avoid high temperature increases lining loss; Frequently observed, and if I found furnace lateral aglow phenomenon, this is the precursor to leak furnace, should take timely closure of intermediate frequency power supply, pour out the liquid, measures such as to prevent furnace leakage accidents. Should also pay attention to in use, and if I found lining becomes very thin, cannot continue to use, should be hit off the old lining redo the new lining, prevent leakage accidents.   另外,由于中频电炉工作在高温,高电压,大电流下。因此,应经常清扫机房、电源柜内和感应线圈连接铜排的灰尘,防止绝缘降低发生故障。经常检查各冷却水路水流、水压是否正常。定期对各部件的连接螺栓、螺母进行紧固,防止接触不良烧毁部件。定期对水冷却系统抽水电机、液压站电机进行保养,清洁液压油,保证设备的正常供水和供油。定期对设备的额定电压,电流进行效验,防止保护电路失灵。定期、正确和精心的维护是延长中频电炉使用寿命和保证安全的重要保障。 In addition, due to the intermediate frequency electric stove working in high temperature, high voltage, large power flow. Therefore, we should often clean the room, power supply and induction coil links contained in the copper platoon dust, preventing insulation lower down. Regularly check the cooling water flow, the water pressure is normal. Regular of the various components of the fastening connection bolt, nut, prevent poor contact burned parts. On a regular basis for water cooling system pump motor, the motor of the hydraulic pressure station for maintenance, clean the hydraulic oil, ensure the normal water supply and drainage. Regularly rated voltage of equipment, the current efficacy, prevent protection circuit failure. On a regular basis, correct and careful maintenance is extending the service life of the intermediate frequency electric furnace and ensure safety.
