High frequency heating furnace knowledge push type continuous high frequency heating furnace continuous

Push type continuous high frequency heating furnace is still the most widely used form of. According to thefurnace temperature system can be divided into two type high frequency heating furnace, three section type high-frequency heating furnace, multipoint heating type high frequency heating furnace.

Two section type continuous high frequency heating furnace

According to the temperature system is divided into theheating period and the preheating period, thecorresponding also ground is divided into heating andpreheating section. The billet heating thin small furnacealso has one side heated, usually both heating. The combustion chamber is arranged at the end part of theburning coal, known as the head of the combustion chamberfurnace, heating furnace arranged on both sides, called the waist. Burning oil or gas stove burner, installed in the end wall on the lower part of the side wall,sometimes also mounted burner.

Two section type has upper and lower surfaces of thecontinuous high frequency heating furnace The proportion of distribution, fuel heating accounts for 30^ ~ 40^, 60^ ~ 70 lower heating”. Because the furnace gas below the float, part of the gas from both sides of the gap, so that the lower part of the heat wasinsufficient; secondly, the cooling water blanks below to take a lot of heat, this part of the heat almost byheating supply; in addition, the billet and pipe contact place to produce black print, lower heating insufficient,black mark phenomenon is more serious, after the material blank to solid bottom section, only the upper heating.Therefore, lower heating should supply more fuel.

When the blank thickness is small (generally less than 20011 dish, can use two section type furnace. But whenthe billet section is thick, after the end of each heatingtemperature difference of inside and outside, in order to eliminate the temperature difference, must extend theheating time, but by the material surface temperaturelimit, if the surface temperature is too high, will produce the heating defects. The two section typecontinuous heating furnace can not meet the requirements of high frequency.
