Medium frequency furnace is a kind of heat treatment equipment, usually used for melting superalloy, stainless steel, high chromium steel and other superalloy materials. As the isolation layer between the melting material and the heat source, the furnace lining plays a crucial role in the melting quality and equipment life. Therefore, the selection of lining materials should follow the following principles: 1. Good high temperature resistance: the temperature in the furnace is high, and it is necessary to choose high temperature resistant materials to ensure that there will be no cracking or deformation of lining under high temperature conditions. 2...

The basic principles of the selection of lining materials mainly include improving the service life of the furnace, reducing costs, saving energy, and considering the performance requirements of the material such as refractance, high temperature structural strength, high temperature chemical stability, resistance to rapid heating and cooling, and volume stability at high temperatures. Furnace lining is an important part of the furnace, and the choice of its material directly affects the performance and service life of the furnace. When choosing lining materials, the following principles need to be considered: 1. Refractoriness and high temperature structural strength: Lining materials must have enough...

How to extend the use of intermediate frequency furnace lining? Here, take a look at it with the small edition of Hubei furnace lining material sales manufacturers! 1, the erosion of the bottom position in the normal use of the lining, the thickness of the lining and the thickness of the bottom of the furnace will slowly thin in the long-term use due to the circulation of hot metal erosion erosion, the intuitive situation is the increase of the furnace capacity, the general lining is eroded 30-50% of the time will be re-knocked off, and then a new furnace building work. From the analysis of the entire lining, where the erosion is obvious, it is at the bottom of the furnace...

Summarize and arrange several methods for determining the life of the lining: 1, when the lining life is approaching, pay attention to the electric furnace frequency meter, voltmeter, ammeter, etc., if the hands of these meters continue to swing under normal working conditions, the lining life will not continue to be used after the end of the work. 2, the circuit working sound obviously becomes "dull", the circuit shell and other grounding body contact the power supply will stop working, indicating that the iron liquid has broken down the furnace lining, should immediately cut off the power to pour the iron liquid inside the oven, stop continuing to use. 3, operation...

Coil cement is a sealing material used to fill the gap between coils and electronic devices, usually consisting of synthetic rubber and filler. It has certain fire resistance and can resist the combustion of the flame at a certain temperature. However, its fire resistance depends on the specific formulation and use environment. Generally speaking, the fire resistance of coil mortar is relatively low and cannot completely replace refractory materials. In situations requiring high safety and fire prevention, professional refractory materials should be used. Therefore, if refractory materials are needed,...

What are the aspects that affect the intermediate frequency furnace lining? Below, and Hubei lining materials sales company Xiaobian together to understand the next! 1, the loading criteria of the intermediate frequency furnace must first determine the reasonable loading amount of the converter, the suitable ratio of hot metal and scrap steel. However, in determining the loading capacity of the converter, in addition to considering the appropriate furnace volume ratio, the appropriate depth of the molten pool should also be considered, so as to protect the bottom of the tube from the impact of the oxygen jet, and the depth of the molten pool must exceed the penetration depth of the oxygen flow to the molten pool. 2, medium frequency furnace oxygen supply criteria...
