Class monitor responsibility before intermediate frequency furnace technology before an intermediate frequency furnace wear what are the symptoms of a: 1 observe furnace wall thickness distribution, probably understand the parts will be punched.
2 after each furnace hot metal pouring, observe whether the lining is the part of the black mark.
3 in the part of the black mark, supplement the reoccupy after with sand.
4 for the sake of safety, not sure to stop using it.
How to clean up the request before the intermediate frequency furnace slag pit down before class monitor responsibility medium frequency furnace answer: I have seen the foundries are classes.
Often in the vicinity of intermediate frequency furnace work what's the harm?
A: medium frequency furnace is a kind of will power frequency 50 hz alternating current into intermediate frequency (
More than 300 hz - 10000 hz)
Induction coil, power supply units, deserve to go up and compensation capacitor, applied the principle of electromagnetic induction heating equipment.
Widely used in non-ferrous metal and black metal and melting, heating.
Such as melting cast iron, ordinary steel, stainless steel, tool steel, copper, aluminum, gold, silver and alloy, etc. ;
Intermediate frequency furnace in the process of oven, the voltage rise not to go up, maintain a: left at 200 v in the first place if there is a problem regardless of intermediate frequency power supply device, intermediate frequency furnace before the furnace should use electric heaters or charcoal fire slowly rising up oven, oven is adverse to the service life of refractory material of the furnace.
In the basic completion of initial oven, should use the crucible will you need a metal melt and pour into intermediate frequency furnace smelting, again to electricity, intermediate frequency power supply device in a furnace.
Slow to do and a half tons of intermediate frequency furnace, need to add capacitance, or mediation panel answer: if it is not the external reason (
The user grid electricity environment)
And its problems cause intermediate frequency system, should be main consideration before the furnace operation.
Before furnace and smelting speed of fast and slow, properly or not is directly related to operation.
When start melting furnace
material, molten steel into the furnace bottom, the above material overhead, the furnaceman must keep pounding furnace, to pound the above materials.
Intermediate frequency furnace is a batch of 380 kilograms, low carbon steel parts, scrap material.
Before the furnace put a: medium frequency furnace is a batch of 380 kg, low carbon steel parts, scrap material.
Furnace before put the aluminium wire, silicon, manganese how much proportion of ingredients, pour molten steel packets before 50 put how many aluminium wire.
How much put aluminium wire.
