Abstract

The reshaping procedure of the annular furnace goes like this: keeping the inner furnace wall, supporting the furnace top temporarily, dismantling the outside furnace wall, modifying the steel structure of the furnace base, with the furnace based formed by centering roll table, inner ring track, outer ring track, top ring steel structure, bottom ring steel structure, inner ring I type steel, outerring I type steel, inner ring stringer, outer ring stringer, fastening fan ring and fan shape steel structure on the bottom and top ring steel structure, building outer ring furnace wall outside thefurnace base, expanding the furnace top at the top of the outer ring furnace end. It is a good reshaping method with productivity, heating ability, and reduced investment.

Description

A kind of extending capacity reformation method of annular furnace
Technical field:
The present invention relates to the rotary heating furnace technical field, is a kind of extending capacity reformation method of annular furnace specifically.
Background technology:
As everyone knows, existing annular furnace is as the Thermal Equipment of the various round members of heating, in case finish Installation and Debugging, its heating efficiency is that productivity ratio, furnace bottom effective width are determined thereupon, it is bigger further to enlarge its heating efficiency difficulty again, makes original annular furnace productivity ratio and heater block specifications and models be subjected to bigger restriction like this, and the specifications and models that boost productivity or increase heater block have only new annular furnace is installed again, thereby it is big investment to occur, takes up an area of problems such as many.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art, and a kind of extending capacity reformation method of annular furnace is provided, mainly solve existing annular furnace extending capacity reformation difficulty and influence productivity ratio and the limited problem of heater block specifications and models.
To achieve these goals, the present invention is achieved in that a kind of extending capacity reformation method of annular furnace, and it comprises following processing step:
A, ring oven wall 2 is motionless in keeping, and supports furnace roof temporarily, removes outer shroud furnace wall 15;
B, steel construction to furnace bottom 1 is transformed, keep the part of motionless furnace bottom 1 to be: centering roller-way 3, interior loop orbit 4, outer loop orbit 5, on encircle steel construction 6, ring steel construction 7, interior ring I-steel 8, outer shroud I-steel 9, interior ring cant beam 10, outer shroud cant beam 11 down: fixing sector circular steel structure 12 on the outer shroud cant beam 11 of outer shroud I-steel 9 upper and lower ring steel constructions 7, sector circular steel structure 12 is connected with following ring steel construction 7 by lacing wire 13, fan-shaped steel structure 14 is installed on sector circular steel structure 12, and fan-shaped steel structure 14 is bolted to connection with last ring steel construction 6;
C builds outer shroud furnace wall 15 in the outside of the fan-shaped steel structure 14 of furnace bottom 1, and ring oven wall 15 tops extend out furnace roof outside simultaneously.
The extending capacity reformation method of a kind of annular furnace of the present invention, the section of its described sector circular steel structure 8 are the handstand triangle.
Compared with the prior art the extending capacity reformation method of a kind of annular furnace of the present invention has outstanding substantive distinguishing features and obvious improvement: owing to increasing sector circular steel structure and fan-shaped steel structure on ring steel construction and the following ring steel construction on the furnace bottom, make the middle footpath of annular furnace become variable, thereby can carry out the extending capacity reformation of annular furnace, can carry out dilatation according to the requirement of productivity ratio and the specifications and models of heater block, reduce investment outlay simultaneously, improve the heating efficiency of annular furnace.
Description of drawings:
Fig. 1---plan structure schematic diagram of the present invention;
Fig. 2---bottom construction schematic diagram of the present invention.
The specific embodiment:
In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing, describe the extending capacity reformation method of a kind of annular furnace of the present invention in detail.
Embodiment 1, referring to Fig. 1,2, ring oven wall 2 is motionless at first keeping on the basis of former annular furnace, the interim furnace roof that supports, remove outer shroud furnace wall 15, again the steel construction of furnace bottom 1 is partly transformed, keep the part of motionless furnace bottom 1 to be: centering roller-way 3, interior loop orbit 4, outer loop orbit 5, last ring steel construction 6, following ring steel construction 7, interior ring I-steel 8, outer shroud I-steel 9, interior ring cant beam 10, outer shroud cant beam 11, guaranteeing under the dynamically balanced prerequisite of full annular stove center of gravity, require to make sector circular steel structure 12 and fan-shaped steel structure 14 according to design size, according to the triangle stability principle, it is the handstand triangular structure that sector circular steel structure 12 is processed into section, by several high-strength bolts sector circular steel structure 12 is fixed on the outer shroud cant beam 11, be welded in down on the ring steel construction 7 as lacing wire 13 with connecting channel-section steel again, again sector circular steel structure 12 is welded on the outer shroud I-steel 9, by connecting bolt fan-shaped steel structure 14 is fixed on the ring steel construction 6, and by sector circular steel structure 12 supports, thereby be processed into the furnace bottom 1 of size conforms extending capacity reformation requirement, build outer shroud furnace wall 15 in the outside of furnace bottom 1, ring oven wall 15 tops extend out furnace roof outside simultaneously, thereby finish the extending capacity reformation of annular furnace.
