Abstract
The utility model relates to a fuel gas spheroidizing annealing furnace comprising a cantalever, a furnace cover, a furnace body, a circulating fan and a shield gas conveying appliance. The utility model is heated by a self recuperative gas burners, inside and outside spaces are divided by an inner barrel, a convection barrel is reserved inside the furnace with convection clearance, the circulating fan is arranged between the two bottoms of the two barrels, and a circulating ventilator is positioned at the well under the bottom of the furnace, the inner barrel bottom is in convex arc shape and is inosculated with the hearth which is in the shape of hollow arc. Thereby the utility model can be forced equally and stably. The utility model has the advantages that: the structure is simple, the operation is convenient and the gas distribution is uniform, in particular to being applicable for the areas where have rich gas resources.
Description
Affiliated technical field
The utility model belongs to general stove, kiln, roaster group, i.e. F27B in International Patent Classification (IPC).Also with to change ferrous metal physical structure group relevant, i.e. CD21D, the particularly spheroidizing annealing furnace of ferrous metal.
Background technology
In the Spheroidizing Annealing of wire rods such as soft steel, medium carbon steel, low alloy steel, dish circle was handled, the equipment of widespread use at present all was electrically heated bell-type furnace and pit furnace.Former structure complexity, troublesome poeration; Latter's furnace atmosphere is poor to fluidity.The former protective atmosphere feeds protection gas by the body of heater bottom, and for example nitrogen, dissociated methanol gas will contain the oxygen air and discharge and realize from the bell vent valve.The self-preheating type fuel burner nozzle is a prior art, comprises the smoke backflow cover of naked light burner, ceramic heat exchanger and band ceramic thermal barrier layer, and it carries out flue gas water conservancy diversion, preheating with flue gas ejector.Through internet retrieval, fail to detect the patent information and academic, the technical periodical that are used for the combustion gas spheroidizing annealing furnace.With " industrial furnace " is keyword, carries out patent retrieval, and all employings electrically heated pattern that detects has bigger difference with the utility model.
The utility model content
The purpose of this utility model provides a kind of spheroidizing annealing furnace.It is simple in structure, and is easy to operate, particularly the furnace atmosphere uniformity.
The new solution that realizes above-mentioned purpose is:
A kind of combustion gas spheroidizing annealing furnace has cantilever at least, has the bell of vent valve, body of heater and the air-circulating fan that vapor pipe is arranged at top, also has the protection gas e Foerderanlage between the bucket and convection current bucket in arriving by body of heater:
The furnace bottom that the ceramic beaverboard of from bottom to top piling up successively, insulating brick, refractory castable are formed, its bottom is cancave cambered surface for plane, top;
Bucket in heat-resisting, the inflexible metal, its upper opening also is connected with the periphery lower edge of bell by sealing-ring, and its underpart is convex globoidal and identical with the cancave cambered surface of furnace bottom;
The convection current bucket that suitable for readingly open wide, there is through hole at the end, its periphery leaves ebb interval with interior barrel;
On the stove axis between convection current bucket and the interior bucket convex globoidal, the strong convection air-circulating fan is arranged, air-circulating fan is fixed on the output axle head of the recirculation blower that is positioned at the furnace bottom well thus;
Several tangential directions enter the self-preheating type fuel burner nozzle between body of heater and the interior bucket, and its smoke backflow cover is fixed on the outer wall of body of heater, and the gas line in the burner is connected with the annular air channel of body of heater by control device.
By the sample stove that above-mentioned direction is made, simple in structure, easy to operate.Because interior bucket can conduct heat and can isolate atmosphere and heating flue gas two spaces, adds the air-circulating fan strong convection, therefore has the advantage of atmosphere homogeneous unanimity; Owing to adopt the combustion gas heating.So resourceful area of particularly suitable combustion gas; Owing to interior bucket and furnace bottom coincide, therefore not only firm but also stressed even.
Description of drawings
Accompanying drawing is embodiment of the utility model, promptly adopts the overall schematic of naked light direct-heating type fuel burner nozzle.Wherein 1, cantilever 2, bell 3, vapor pipe 4, convection current bucket 5, interior bucket 6, air-circulating fan 7, furnace bottom 8, recirculation blower 9, smoke backflow cover 10, body of heater 11, flue
Embodiment
A kind of combustion gas spheroidizing annealing furnace, the body of heater 10 and the air-circulating fan 6 of vapor pipe 3 arranged at bell 2, the top that have cantilever 1 at least, has a vent valve, also has the protection gas e Foerderanlage between the bucket 5 and convection current bucket 4 in arriving by body of heater 10:
The ceramic beaverboard of from bottom to top piling up successively, insulating brick, refractory matter are annotated the furnace bottom 7 that waters composition, and its bottom is cancave cambered surface for plane, top;
The convection current bucket 4 that suitable for readingly open wide, there is through hole at the end leaves ebb interval with interior bucket 5 around it;
On the stove axis between convection current bucket 4 and interior bucket 5 convex globoidals, strong convection air-circulating fan 6 is arranged, air-circulating fan 6 is fixed on the output axle head of the recirculation blower 8 that is positioned at the furnace bottom well thus;
Several tangential directions enter the self-preheating type fuel burner nozzle between body of heater 10 and the interior bucket 5, and its smoke backflow cover 9 is fixed on the outer wall of body of heater 10, and the gas line in the burner is connected with the annular air channel 11 of body of heater 10 by control device.
The self-preheating type fuel burner nozzle is naked light direct-heating type burner; The flue gas ejector supporting with it is complementary with the annular flue 11 that is positioned at body of heater 10 tops.
Described Gas controller spare mainly refers to open slowly gas electromagnetic valve, manual regulation stopcock, corrugated tube, orifice plate; The control device of combustion air mainly refers to air butterfly valve, manual regulation stopcock, orifice plate, corrugated tube.This be ready-made commercial natural gas burner in this example with 8, whole device can divide two-layer up and down intersection to install on body of heater 10, uses the same annular flue 11 in top, but annular air channel is separately arranged up and down, as fuel gas source.
