Abstract
The invention discloses a kind of rotary heating furnace, the interior wall (12) and exterior wall (11) set including concentric, preheating section (2) is sequentially arranged between the interior wall (12) and exterior wall (11), bringing-up section (3), soaking zone (4), enter bin gate (5), described rotary heating furnace (1) is additionally provided with discharge door (6), entering between bin gate (5) and discharge door (6), provided with insulated wall (7), top of the top of described insulated wall (7) less than interior wall (12) and exterior wall (11), in the annular space that insulated wall (7) and interior wall (12) and exterior wall (11) are formed, fiberfill fibers module (13).Using above-mentioned technical proposal, on the premise of too many weight is not increased, and can plays good heat insulating effect.
Description
Technical field
The invention belongs to the technical field of steel and iron industry production equipment.A kind of more particularly it relates to annular-heating
Stove.
Background technology
In increasingly competitive market, each enterprise reduces cost what idea was tried, improves the competition of oneself
Power.Product quality is one in steel industry influences the significant index of cost.
Rotary heating furnace sets preheating section, bringing-up section, soaking zone, reasonable distribution length ratio.It is easy to individually adjustment and control
Make each section of temperature, the discharging opening and feeding mouth of annular furnace soaking zone close to.
In the prior art, discharging opening and feeding mouth are heat-insulated by one section of one meter of high insulated wall, and insulated wall is apart from furnace bottom
600mm.Cause soaking zone temperature to decline in pan feeding blow-on Men Shihui, so as to influence to forge temperature, will also result in feeding mouth temperature
It is too high, less than the 600 DEG C requirements of the steel grade pan feeding temperature such as similar D2 can not be performed.
The content of the invention
The present invention provides a kind of rotary heating furnace, and the purpose is to improve insulation, effect of heat insulation.
To achieve these goals, the technical scheme taken of the present invention is：
The rotary heating furnace of the present invention, including the interior wall and exterior wall that concentric is set, are pressed between the interior wall and exterior wall
Order sets preheating section, bringing-up section, soaking zone, enters bin gate, and described rotary heating furnace is additionally provided with discharge door, is entering bin gate with going out
Between bin gate, provided with insulated wall, described heat-insulated coping is less than interior wall and outer coping, in insulated wall and interior wall and outside
The annular space that wall is formed, fiberfill fibers module.
Described heat-insulated coping is lower 30mm than interior wall and outer coping.
The bottom of described insulated wall and the distance of furnace bottom are 30mm.
Described bringing-up section includes three sections of one section of heating, two sections of heating and heating.
The present invention uses above-mentioned technical proposal, and on the premise of too many weight is not increased, and can plays good thermal insulation separation
Thermal effect.
Brief description of the drawings
Mark is briefly described as follows in content shown in accompanying drawing and figure：
Fig. 1 is the overlooking the structure diagram of the present invention；
Fig. 2 is the body of heater cross-sectional view of the present invention.
In figure mark for：
1st, rotary heating furnace, 2, preheating section, 3, bringing-up section, 4, soaking zone, 5, enter bin gate, 6, discharge door, 7, insulated wall, 8,
One section of heating, 9, two sections of heating, 10, three sections of heating, 11, exterior wall, 12, interior wall, 13, fibre module, 14, furnace bottom.
Embodiment
Below against accompanying drawing, by the description to embodiment, embodiment of the invention is made further details of
Illustrate, to help those skilled in the art to have more complete, accurate and deep reason to inventive concept of the invention, technical scheme
Solution.
Structure of the invention as shown in Figure 1 and Figure 2, it is a kind of rotary heating furnace, includes the He of interior wall 12 of concentric setting
Exterior wall 11, preheating section 2, bringing-up section 3 are sequentially arranged between the interior wall 12 and exterior wall 11, soaking zone 4, enters bin gate 5, it is described
Rotary heating furnace 1 be additionally provided with discharge door 6, entering between bin gate 5 and discharge door 6, provided with insulated wall 7.The present invention is to ensure that
The heat-insulated mode of hot arc and feeding mouth temperature.
In order to solve the problems, such as that prior art exists and overcomes its defect, realize and improve insulation, the invention mesh of effect of heat insulation
, the technical scheme that the present invention takes is：
As shown in Figure 1 and Figure 2, rotary heating furnace of the invention, wherein, the top of insulated wall 7 is less than interior wall 12 and exterior wall 11
Top, in the annular space that insulated wall 7 and interior wall 12 and exterior wall 11 are formed, fiberfill fibers module 13.
Using above-mentioned technical proposal, on the premise of too many weight is not increased, and can plays good heat insulating effect.
The top of described insulated wall 7 is lower with the top of exterior wall 11 30mm than interior wall 12.
The bottom of described insulated wall 7 and the distance of furnace bottom 14 are 30mm.
By analysis, determine to transform prior art, destroy original partition wall, build by laying bricks or stones again for away from furnace bottom 30mm every
Wall, after destroying original partition wall, it is by two water cooled pipeline load-bearing to find whole partition wall, if partition wall is integrated poured, worries two
Root water pipe load-bearing is inadequate, therefore determines that pouring into a mould whole partition wall by original volume moves down 30mm.Upper quartered top is to furnace roof
30mm distances are filled by filling in fibre module, i.e., do not increase how much weight, and and can plays heat insulating effect.
Whole partition wall, which is poured into a mould, by original volume moves down 30mm.Upper quartered top to furnace roof 30mm distances by filling in fiber
Module is filled, i.e., how much weight is not increased, and can plays heat insulating effect.
Described bringing-up section 3 include heating one section 8, heating two section 9 and heating three section 10.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that present invention specific implementation is not by aforesaid way
Limitation, as long as the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is employed, or without changing
Enter and the design of the present invention and technical scheme are directly applied into other occasions, within protection scope of the present invention.
