Description

A kind of car-type heat treating furnace parallels

Technical field

The utility model is related to field of engineering technology, more particularly to a kind of car-type heat treating furnace parallels.

Background technology

Large-scale workpiece is required in heat treatment using the parallels that build is larger below workpiece, so that furnace gas convection current makes Workpiece heat is uniform, and also to prevent some irregular long-axle workpieces from occuring bending and deformation in high-temperature heating process. It is easy aging breakage and difficult using the parallels that refractory brick is formed by stacking, is unfavorable for adjusting parallels spacing.Using build compared with Although big forged steel solves the problems, such as refractory brick parallels cracky and difficult as parallels, but give workpiece heat process In also simultaneously heated to forged steel parallels, forged steel parallels build is larger, not only increases energy expenditure, and be used for multiple times Deformation is serious afterwards, increases cost input and energy consumption.

Utility model content

In view of the foregoing deficiencies of prior art, the purpose of this utility model is to provide a kind of car-type heat treating furnaces With parallels, which reduces energy expenditure, avoids the occurrence of deformation, reduces production cost.

In order to achieve the above objects and other related objects, the utility model provides：The utility model provides a kind of car-type Heat-treatment furnace parallels comprising shell is placed with multiple cast forging in the shell vertically, the cast forging with it is described Shell is welded to connect by bar shaped iron；Gap and the adjacent cast forging between the cast forging and the shell it Between gap be filled with sand or concrete.

In an embodiment of the utility model, the shell both sides are respectively arranged with suspension hook.

In an embodiment of the utility model, the shell is made of mild steel steel plate.

In an embodiment of the utility model, the thickness of the mild steel steel plate is 30-50mm.

In an embodiment of the utility model, the shape of the shell is cube shaped or cylindrical.

As described above, a kind of car-type heat treating furnace parallels of the utility model, has the advantages that：

The utility model organically combines sand or concrete with cast forging, mild steel steel plate so that the parallels of acquisition Intensity, resisting breakage ability and non-deformability greatly increase, and extend service life；Compared to old system forged steel parallels, originally The energy expenditure of the parallels of utility model reduces about 5%.

Specific implementation mode

Illustrate that the embodiment of the utility model, those skilled in the art can be by this theorys below by way of specific specific example Content disclosed by bright book understands other advantages and effect of the utility model easily.The utility model can also be by addition Different specific implementation modes are embodied or practiced, and the various details in this specification can also be based on different viewpoints and answer With carrying out various modifications or alterations under the spirit without departing from the utility model.It should be noted that the case where not conflicting Under, the feature in following embodiment and embodiment can be combined with each other.

It should be noted that the diagram provided in following embodiment only illustrates the basic of the utility model in a schematic way Conception, component count, shape when only display is with related component in the utility model rather than according to actual implementation in schema then And size is drawn, when actual implementation kenel, quantity and the ratio of each component can be a kind of random change, and its assembly layout Kenel may also be increasingly complex.

Embodiment 1

As shown in Figure 1, a kind of car-type heat treating furnace includes with parallels：By the shell 1 for the sealing that mild steel steel plate is constituted, Multiple cast forging 2 are placed in shell 1 vertically, cast forging 2 is welded to connect with shell 1 by bar shaped iron；Cast forging 2 with The gap between gap and adjacent tubes swaged forging part 2 between shell 1 is filled with sand or concrete.

The thickness of mild steel steel plate is 30-50mm.As an example, the thickness of mild steel steel plate is 40mm or 45mm.

If parallels needs often move, a suspension hook can be respectively welded in 1 both sides of shell of parallels, facilitate unloading.

In the present embodiment, the shape of shell 1 is cube shaped, and rectangular workpiece is facilitated to use.

The preparation process of above-mentioned car-type heat treating furnace parallels, includes the following steps：

1) thickness is used to be welded into the shell 1 that upside is provided with opening for 30-50mm mild steel steel plates；The two of shell 1 Hook is respectively welded in side, facilitates unloading.

2) cast forging 2 is vertically placed in shell 1, compact distribution between cast forging 2, then uses bar shaped iron by cast It is welded with shell 1 bottom of forging 2；

3) by between cast forging 2 and shell 1 gap and adjacent tubes swaged forging part 2 between gap using sand carry out Filling, it is stocky to sand after filling up, then the opening of shell 1 is sealed with steel plate, and steel plate and shell 1 are welded.

By the way that sand, cast forging and mild steel steel plate are organically combined so that the intensity of the parallels of acquisition, resisting breakage energy Power and non-deformability greatly increase, and extend the service life of parallels.

Embodiment 2

As shown in Fig. 2, the technical characteristic of embodiment 2 is substantially essentially identical with embodiment 1, but unlike, shell 1 Shape is cylinder, and circular workpiece is facilitated to use.

The above embodiments are only illustrative of the principle and efficacy of the utility model, new not for this practicality is limited Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the revealed essence of the utility model All equivalent modifications completed under refreshing and technological thought or change, should be covered by the claim of the utility model.
