Intermediate frequency furnace crucible wall thickness requirements

Intermediate frequency furnace crucible wall thickness requirements between an intermediate frequency furnace crucible technology and coil with what filler material answer: general crucible manufacturers will provide, are filled with sand refractory material. The influencing factors of intermediate frequency furnace steelmaking furnace life? Intermediate frequency furnace crucible wall thickness requirements answer: the factors influencing the service life of crucible is very complex, main factors are the following several aspects. 11 crucible crucible material according to the features of material chemical composition and physical and chemical properties have great influence to the service life of crucible. The impurities, refractory at high temperature to form low melting point compound, which reduces the refractoriness of refractory materials. As the fire. Graphite crucible of intermediate frequency furnace heating temperature up to how much a: too general? ! There are three such a few factors to consider 1, how big is the power of the heating device? - - At constant in article 2, 3, 4, the greater the power, the higher the temperature - - But there will be a certain limit, can't continue to move up indefinitely. 2, heating room have how old? - - At constant at 1, 3, 4, the smaller the space, the higher the temperature, heating time is 3? - - In 1. The steel factory five basic questions to answer: how to reduce the scale? 1 reduce furnace residence time; 2 to minimize air leakage phenomenon, the stove oven door closed at any time; 3 good control rolling rhythm; Two medium frequency furnace, how ingredients most save cost, but does not affect the rate of steel. A ton of intermediate frequency furnace bottom on which one circle of intermediate frequency furnace crucible wall thickness requirements a: it should be said that at the bottom of the intermediate frequency furnace crucible induction coil, the bottom of the distance. Under normal circumstances, the crucible induction coil, the bottom than at the bottom of the 1 - Induction coil, 2 laps, flat, at least not less than, or at the bottom of the molten steel melting, the temperature is low. Medium frequency induction coil, furnace bottom to the distance of the answer: it should be said that at the bottom of the intermediate frequency furnace crucible induction coil, the bottom of the distance. Under normal circumstances, the crucible induction coil, the bottom than at the bottom of the 1 - Induction coil, 2 laps, flat, at least not less than, or at the bottom of the molten steel melting, the temperature is low. 1 acid lining material: carbon steel smelting. Quartz sand ( 20/40) 40%, quartz sand, 50/100) 5 ~ 2% ( Plus) 2%, water ( Plus) 。 Quartz sand should be magnetic separation, remove the ferromagnetic material. Alkaline lining: for alloy steel smelting. Magnesia ( A 4 x 4 mm sieve) 96%, refractory clay, No. 100. Used to cast copper medium frequency furnace and power frequency furnace have why to distinguish? A: intermediate frequency furnace and power frequency furnace has the following main difference: 1, intermediate frequency furnace power density is larger, high productivity, namely under the same stirring power, the same capacity, intermediate frequency furnace can be input 3 times the power frequency furnace power, in other words, the same power medium frequency furnace crucible size was only about a third of the power frequency furnace crucible size in large oven, because of the influence of the sensor wire Qing current and voltage. What is the difference between intermediate frequency and power frequency answer: according to the frequency of the high and low to differentiate, the intermediate frequency ( MF MediumFrequency) Refers to the spectrum from 300 KHZ to 3000 KHZ frequency, most AM radio. According to its position and function to classification in the circuit: an intermediate frequency ( IntermediateFrequency) Refers to the high frequency signal after frequency conversion and get a signal. Intermediate frequency has two meanings: one of them.
is frequently used by people in daily life since it can improve induction melting machine and induction heating equipment.
