Abstract

The utility model relates to a heat treating device for a metal. The utility model comprises a furnace lining which is supported by a steel structure, and a furnace chamber which is arranged in the furnace lining. The wall of the furnace lining is provided with a burner nozzle. A heat exchanger is arranged on the flue of the furnace chamber. The inlet of a steel wire is positioned at the point of the flue of the furnace chamber. A preheating section, a heating section, and a holding section are orderly arranged on the running direction of the steel wire. The upper parts of the heating section and the holding section are respectively provided with one to two burner nozzles. The running direction of the furnace gas is opposite to the running direction of the steel wire. The lower side each burner nozzle is provided with a grid-shaped arch.

Description

Efficient naked fire heat treating furnace for wire

The utility model relates to metal heat treatmet equipment, specifically a kind of heat treatment furnace that is exclusively used in Steel Wire Heat Treatment, has preheating section, heating zone and soaking zone in furnace chamber.

The energy consumption of China's Steel Wire Heat Treatment accounts for half of national Steel Wire Products Industry energy consumption, the good and bad quality and the consumption of raw materials that directly influences steel wire product of heat treatment furnace.Generally use properties is better than the fuel oil of retort furnace and the naked light heat treatment furnace of combustion gas abroad, but also there are some problems in this class type of furnace, adopt the side of One's name is legion to burn as some type of furnace and chew heating, employing flue gas that has and steel wire traffic direction are decoration form in the same way.Thereby, both be unfavorable for energy-conservationly, can not control the furnace atmosphere of heating zone and soaking zone again well, to chew much because burn, furnace temperature is wayward again, and the fuel charge that each burning is chewed is less, so control accuracy is lower.

The purpose of this utility model is that a kind of flue gas of design is opposite with the traffic direction of steel wire, preheating section is set, the heat treatment furnace of heating zone and soaking zone in furnace chamber.

Its main technical schemes is to be the stove masonry in steel construction (11).In the stove masonry is furnace chamber, on stove masonry wall, install to burn and chew, on the flue (8) of furnace chamber, interchanger (7) is set, the import of steel wire is positioned at the flue (8) of furnace chamber and locates, on the traffic direction (A) of steel wire, set gradually preheating section (9), heating zone (6) and soaking zone (2), on the top of heating zone (6) and soaking zone (2) burning is set and chews (3), (1), and, the traffic direction of furnace gas (B) is opposite with the traffic direction (A) of steel wire, chews in burning " grid " shape arch (12) is set down.The oil inlet quantity utilization that burning is chewed can be regulated the oil pump of rotating speed and directly control.

The utility model has the advantages that because the burning that all is provided with single vertical layout at heating zone and soaking zone is chewed, chew setting " grid " shape arch down in burning, furnace gas and steel wire traffic direction are reverse, thereby guaranteed that soaking zone lacks the control of oxygen or oxygen debt atmosphere, and improved the thermo-efficiency of stove, steel wire heating is even, and oxidization burning loss is few.

Fig. 1 is a structure iron of the present utility model.

Fig. 2 is the C-C view of Fig. 1.

Fig. 3 is the D-D view of Fig. 1.

As shown in the figure: steel construction (11) is held stove masonry (10), in the stove masonry is furnace chamber, the stove masonry is built into by refractory materials, and wall covers the full fibre fire-proof layer of one deck (4) within it, traffic direction along steel wire in furnace chamber sets gradually preheating section (9), heating zone (6) and soaking zone (2), on the flue (8) of furnace chamber, interchanger (7) is set, the import of steel wire is positioned at the flue place of furnace chamber, respectively there is the burning facing to flue of a horizontal positioned to chew (3) on the top of heating zone (6) and soaking zone (2), (1), in soaking zone and heating zone, near the one group of grid-like arch (12) that also is provided with respectively that burning is chewed, (5) are the top of body of heater among the figure.

Claims (2)

1, a kind of efficient naked light Heat Treatment Furnace for Steel Wire, in steel construction (11), be the stove masonry, in the stove masonry is furnace chamber, on stove masonry wall, install to burn and chew, on the flue (8) of furnace chamber, interchanger (7) is set, it is characterized in that the import of steel wire is positioned at the flue of furnace chamber (8) and locates, on the traffic direction (A) of steel wire, set gradually preheating section (9), heating zone (6) and soaking zone (2), on the top of heating zone (6) and soaking zone (2) 1-2 burning is set respectively and chews (3), (1), and, the traffic direction of furnace gas (B) is opposite with the traffic direction (A) of steel wire, chews in burning " grid " shape arch (12) is set down.

2, heat treatment furnace according to claim 1 is characterized in that burning the oil pump that the oil inlet quantity utilization of chewing can regulate rotating speed and directly controls.
