Abstract
The utility model discloses a bearing structure used to release thermal stress of a heating furnace, which comprises a metallically constructed base plate arranged at the bottom of a heating furnace body, a civil engineering sole plate arranged on a civil engineering foundation, and heat resisting flexible materials provided between the metallically constructed base plate and the civil engineering sole plate. The beneficial effects of the utility model lie in that: the bearing structure is capable of effectively eliminating the thermal stress from the steel structure in the heating furnace, reduces the chances of deformation of a furnace body and makes the furnace body integrated into one piece, which substantially prolongs the service lifetime of a heating furnace.
Description
Technical field
The utility model relates to a kind of load-carrying members that are used to discharge the heating furnace thermal stress, particularly a kind of load-carrying members that can absorb the length travel and the lateral displacement of heating furnace body thermal expansion generation and effectively discharge the body of heater thermal stress.
Background technology
Heating furnace is one of visual plant of metallurgical, mechanical industry, and it is to utilize fuel to produce thermal-flame and flue gas as thermal source in the burner hearth internal combustion, comes workpiece in the heating furnace, makes its temperature that reaches the technological operation regulation, heats or heat treatment requirements to satisfy workpiece.
According to different needs and purposes, the structure of heating furnace is varied, but all has heating furnace body.Heating furnace body adopts steel construction more, and mostly is a box-shaped steel structure of being made up of various shaped steel and steel plate, is about tens meters, wide about tens meters, in be lined with heat-resistant insulation material.Temperature is often up to more than 1000 ℃ in the burner hearth of heating furnace body.Therefore, heating furnace body is different with common normal temperature equipment steel construction, except that bearing gravity load, also will need to bear thermic load.Because the heating furnace body volume is big, the furnace chamber temperature height.Thereby it is very huge by the thermal stress of thermic load production.So for the heating furnace body steel construction, it is very important how effectively discharging the thermal stress that steel construction produces owing to high temperature.
In the prior art, in order effectively to discharge the thermal stress that steel construction produces owing to high temperature, usually the heating furnace body steel construction is divided into plurality of sections on the furnace superintendent direction, being connected between section and the section adopts the mounting hole bolt to connect, to tackle the stress of thermal expansion generation.But the structure of segmented impacts body of heater integral body easily first, and because this structure is a solid structure, aspect the thermal stress of reply thermal expansion generation, is difficult to reach preferable effect.In the prior art, contact position for heating furnace body and foundation of civil work base plate, the steel construction base plate of employing heating furnace body directly is placed on the structure on the foundation of civil work base plate, this structure can cause equally can not be effectively and discharge reliably because the thermal stress that thermal expansion produces, and causes the furnace binding distortion and influenced service life of body of heater greatly.
Therefore, how to provide a kind of structure, can effectively discharge the thermal stress of heating furnace body, become the problem that those skilled in the art need solve.
The utility model content
Technical scheme to be solved of the present utility model provides a kind of load-carrying members that are used to discharge the heating furnace thermal stress, to solve the deficiencies in the prior art.
For solving technique scheme, the utility model provides a kind of load-carrying members that are used to discharge the heating furnace thermal stress, comprising: the metal structure base plate that is arranged on the heating furnace body bottom; Be arranged on the foundation of civil work base plate on the foundation of civil work; And be arranged on heat-resistant flexible material between described metal structure base plate and the described foundation of civil work base plate.
As one of preferred version of the present utility model, have some projectioies of the position of the described heat-resistant flexible material of restriction on the described metal structure base plate.
As one of preferred version of the present utility model, have some projectioies of the position of the described heat-resistant flexible material of restriction on the described foundation of civil work base plate.
As one of preferred version of the present utility model, the described heat-resistant flexible material side of being body.
As one of preferred version of the present utility model, described projection has four, is fitted on four sides of described side's body.
As one of preferred version of the present utility model, described heat-resistant flexible material is a heat resistant rubber.
As one of preferred version of the present utility model, described metal structure base plate is the steel construction base plate.
The beneficial effects of the utility model are: can eliminate the furnace binding thermal stress effectively, reduce the body of heater distortion, make body of heater can be designed to one, improve the service life of stove greatly.
Description of drawings
Fig. 1 is the structural representation that is used to discharge the load-carrying members of heating furnace thermal stress.
The specific embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
A kind of load-carrying members that are used to discharge the heating furnace thermal stress comprise:
Be arranged on the metal structure base plate 1 of heating furnace body bottom;
Be arranged on the foundation of civil work base plate 3 on the foundation of civil work; And
Be arranged on the heat-resistant flexible material 2 between described metal structure base plate and the described foundation of civil work base plate.
Further, have on the described metal structure base plate 1 restriction described heat-resistant flexible material 2 the position some protruding 41.By these projectioies 41, heat-resistant flexible material 2 is defined with the position of the contact-making surface of metal structure base plate 1, can prevent that the heat-resistant flexible material 2 and the relative position of metal structure base plate 1 from too big skew taking place.
Further, have on the described foundation of civil work base plate 3 restriction described heat-resistant flexible material 2 the position some protruding 42.By these projectioies 42, heat-resistant flexible material 2 is defined with the position of the contact-making surface of foundation of civil work base plate 3, can prevent that the heat-resistant flexible material 2 and the relative position of foundation of civil work base plate 3 from too big skew taking place.
Further, described heat-resistant flexible material 2 side's of being bodies.
Further, described protruding 41 and 42 have four respectively, are fitted in respectively on four sides of described side's body.
Further, described heat-resistant flexible material is a heat resistant rubber.
Further, described metal structure base plate is the steel construction base plate.
In sum, be lined with heat-resistant flexible material 2 between metal structure base plate 1 and the foundation of civil work base plate 3.These heat-resistant flexible material 2 decapacitation are born outside the stove overall weight (normal load), can also absorb length travel and lateral displacement that the body of heater thermal expansion produces, eliminate the furnace binding thermal stress effectively, reduced the body of heater distortion, make body of heater can be designed to one, improved the service life of stove greatly.
Above embodiment is the unrestricted the technical solution of the utility model in order to explanation only.Any modification or partial replacement that does not break away from the utility model spirit and scope all should be encompassed in the middle of the claim scope of the present utility model.
