Description

A kind of bright annealing furnace

Technical field

This utility model is related to annealing furnace.

Background technology

In the process of manufacture of copper alloy wlding, due to there is processing hardening, need to carry out intermediate annealing.And in annealing During, directly anneal if do not carried out atmosphere protection, then oxidative phenomena is very serious, not only bad for the processing of lower road, and The loss of material is also very big, is also unfavorable for the quality control of final finished.

In order to solve the above problems, typically adopt bright annealing furnace, in use, according to technological requirement, when coming out of the stove, After furnace temperature is cooled to 300 DEG C, just capable of hoisting go out flue carry out air-cooled, air-cooled come out of the stove to after 100 DEG C.In actual production process, Due to overlength cool time (40 hours) it is impossible to meet produce and End-Customer date of delivery needs, operator produce tight In the case of, frequent violation operation, that is, furnace temperature just flue is hung out when 600 DEG C, due to the high-temperature machinery of flue material Can drastically decline, flue well damage, the material oxidation through bright annealing is seriously it is impossible to ensure product quality.

Content of the invention

The purpose of this utility model is to provide a kind of bright annealing furnace, greatly shortens cool time and extends making of flue Use the life-span.

The technical scheme realizing above-mentioned purpose is：

A kind of bright annealing furnace, including：

The burner hearth on embedded ground；

It is fastened around the neck part of described burner hearth cervical region；

The sealing member of annular；

Insert described burner hearth, and the flue connecting by described sealing member with the sealing of described neck part；

It is fixed on the electric heating part between described burner hearth and described flue；

Cover the bell on described flue；

It is opened in described burner hearth cervical region at least two vents of neck part described in insertion；And

Multiple insulation drawers of each described vent are filled in sealing.

In above-mentioned bright annealing furnace, the quantity of described vent and described insulation drawer is all three.

The beneficial effects of the utility model are：

This utility model passes through to increase vent, accelerates to distribute heat, substantially reduce cool time, from original during cooling Be down within 40 hours 9 hours about.Simultaneously it is not necessary to flue is hung out cooling, save production function space, effectively reduce work People's labor intensity, also extends the service life of flue it is ensured that the quality of product.

Brief description

Fig. 1 is the structure sectional view of bright annealing furnace of the present utility model.

Specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Refer to Fig. 1, bright annealing furnace of the present utility model, including burner hearth 1, neck part 2, sealing member 3, flue 4, electricity Heating member 5, bell 6, at least two vents 7 and the multiple insulation drawers 8 with quantity such as vents 7.In the present embodiment, lead to The quantity of air port 7 and insulation drawer 8 is three.

Burner hearth 1 bottom is embedded into ground 9.

Neck part 2 annular, is fastened around the cervical region of burner hearth 1.

Sealing member 3 annular, is fastened around the top of burner hearth 1.

Burner hearth 1 is inserted in the bottom of flue 4, and the top of flue 4 is passed through sealing member 3 and connected with neck part 2 sealing, so, Form a confined space, electric heating part 5 is fixed in this confined space, is actually attached to burner hearth between burner hearth 1 and flue 4 1 inwall.Bell 6 covers on flue 4.

Three vents 7 are around the cervical region being opened in burner hearth 1, and straight-flow furnace neck member 2 is to connect confined space.Each leads to A corresponding insulation drawer 8 is filled in air port 7.

In prior art, 800 DEG C of former annealing temperature is cooled to 300 DEG C and leans on Temperature fall, because stove has sealing thermal insulation Performance (takes electricity during the bad then heating of sealing thermal insulation performance), and cooling is slow, at least needs 35 hours.And in the present embodiment, heating Clog vent 7 with insulation drawer 8 during insulation, do not affect heat-insulating property.In cooling, take out insulation drawer 8, on a mouth Put an aerator to blow, another two mouths, as air outlet, so greatly shorten cool time.And, because same In individual space for collecting ashes in a stove, cooling, it is not necessary to flue is hung out cooling, has been saved production space, has been substantially reduced labor strength.Meanwhile, because Radiated by vent, substantially prolongs the service life of flue, also ensure that the quality of product.

Above example is only for illustration of the utility model, rather than to restriction of the present utility model, relevant technical field Technical staff, in the case of without departing from spirit and scope of the present utility model, can also make various conversion or modification, because This all equivalent technical scheme also should belong to category of the present utility model, should be limited by each claim.

Claims (2)

1. a kind of bright annealing furnace is it is characterised in that include：

The burner hearth on embedded ground；
