Abstract

The utility model discloses a hearth bottom of an annealing furnace. The hearth bottom of the annealing furnace comprises fire-resistant cotton, refractory bricks, an air flue and a stainless steel cover plate, wherein the fire-resistant cotton is paved at the bottom of the hearth bottom; the refractor bricks are paved on the fire-resistant cotton; the refractory bricks are paved on the two sides of the hearth bottom; the refractory bricks on the two sides of the hearth bottom and the refractory bricks at the bottom of the hearth bottom form the air flue; the stainless steel cover plate is arranged on the air flue. The hearth bottom of the annealing furnace has the characteristics of high heat utilization ratio, low rejection rate, short heating time and high cooling speed.

Description

At the bottom of a kind of annealing furnace burner hearth
Technical field
The utility model belongs to heat treatment process mechanical field, at the bottom of being specifically related to a kind of annealing furnace burner hearth.
Background technology
Annealing furnace is widely used in the Field of Heat-treatments such as copper clad aluminum wire production.
At the bottom of annealing furnace burner hearth, be the key position of annealing furnace, the structure construction at the bottom of annealing furnace burner hearth directly has influence on the quality of final heat treated article and energy consumption, production efficiency.
At present, annealing furnace burner hearth bottom structure is all the groove being built into refractory brick, places heater strip in groove, in groove upper cover stainless-steel sheet as base plate, discharging frame again on base plate.At the bottom of the burner hearth of this structure, when burner hearth heats up, bin, stainless steel drop-bottom and refractory brick etc. all must be heated, heat temperature raising is chronic, power consumption is very large, and when needs are lowered the temperature annealing furnace, short period of time temperature can not be fallen, and has extended life cycle of the product.
Summary of the invention
The purpose of this utility model is, at the bottom of a kind of annealing furnace burner hearth is provided, at the bottom of this burner hearth, with refractory brick, is built into air channel, by the hot blast in air channel, directly give heating material, material is heated soon, is heated evenly, can save 30% the energy, can shorten 60% heat-up time, and temperature fall time also can shorten 40%.
In order to realize the utility model, the utility model is taked following technical scheme:
At the bottom of a kind of annealing furnace burner hearth, it comprises fire-resistant cotton, refractory brick, air channel and stainless steel cover plate.Wherein at the bottom of burner hearth, bottom is equipped with fire-resistant cotton, above fire-resistant cotton, is covered with refractory brick; Both sides at the bottom of burner hearth are covered with the refractory brick of refractory brick also and bottom at the bottom of burner hearth and form air channel, are provided with stainless steel cover plate above air channel.
At the bottom of above-mentioned a kind of annealing furnace burner hearth, on described stainless steel cover plate, be evenly drilled with circular hole.
At the bottom of a kind of annealing furnace burner hearth, from the wind of annealing furnace wind wing, be passed down through and be positioned at heater strip region, burner hearth bottom both sides, form high-temperature hot-air and be sent to the soaking that circulates in Li, air channel, air channel, high-temperature hot-air be upward through circular hole on stainless steel cover plate contact object to be annealed and to heating; After heating, hot blast is again annealed stove wind wing and passes heater strip region, burner hearth bottom both sides to blowing down, completes the circulating-heating to object.
At the bottom of a kind of annealing furnace burner hearth of the utility model, the hot blast soaking that circulates in air channel, the circular hole on stainless steel cover plate guarantees ventilation effect, and copper clad aluminum wire product object is heated evenly, scrap rate is low; The utilization ratio of heat is high, and heat-up time is short, only needs current annealing furnace 70% power, and can shorten 60% heat-up time, and temperature fall time also can shorten 40% simultaneously.
Accompanying drawing explanation
Fig. 1 is a kind of annealing furnace burner hearth of the utility model bottom structure schematic diagram.
Fig. 2 is A-A sectional view in Fig. 1.
In figure, fire-resistant cotton 1, air channel 2, stainless steel cover plate 3, refractory brick 4.
Embodiment
Embodiment 1:
As shown in the figure, at the bottom of a kind of annealing furnace burner hearth, it comprises fire-resistant cotton 1, refractory brick 4, air channel 2 and stainless steel cover plate 3.Wherein at the bottom of burner hearth, bottom is equipped with fire-resistant cotton 1, fire-resistant cotton 1 and is covered with refractory brick 4 above; Both sides at the bottom of burner hearth are covered with the refractory brick 4 of refractory brick 4 also and bottom at the bottom of burner hearth and form air channels, are provided with stainless steel cover plate 3 above 2 air channels.
As shown in the figure, on described stainless steel cover plate, be evenly drilled with the circular hole 5 that diameter is 26mm.
As shown in the figure, at the bottom of a kind of annealing furnace burner hearth, from the wind of annealing furnace wind wing, through being positioned at heater strip region, burner hearth bottom both sides, forming high-temperature hot-air and be sent to 2 li, air channel, 2 li of circulation soaking in air channel, high-temperature hot-air contacts object to be annealed heating for it through the circular hole on stainless steel cover plate 3.After heating, hot blast is again annealed stove wind wing and passes heater strip region, burner hearth bottom both sides to blowing down, completes the circulating-heating to object.
At the bottom of a kind of annealing furnace burner hearth of the utility model, be compared with the prior art, have that heat utilization ratio is high, scrap rate is low, the feature that heat-up time is short and cooling is fast.
