Abstract
The method for prefabricating of large-size stainless steel groove tank base plate under a kind of hot environment, it is characterised in that comprise the following steps：A, the specification according to arrival steel plate, typesetting figure is drawn by design and code requirement to base plate；B, blanking is carried out according to typesetting figure, to ensure the accuracy of physical dimension, steel plate cutting is cut with semi auto cutting machine；C, open up groove in strict accordance with the requirement of drawing；D, negative should carry out preservative treatment in bottom surface.The method for prefabricating of large-size stainless steel groove tank base plate has making step reasonable in design, groove tank base plate making high precision and groove tank base plate quality reliability, is that solid foundation advantage is created in next step assembling under hot environment of the invention.
Description
Technical field
It is a kind of method for prefabricating of large-size stainless steel groove tank base plate under hot environment specifically the present invention relates to a kind of method for prefabricating of groove tank base plate.
Background technology
Chinese patent CN102069307 B disclosed a kind of large-scale flat storage tank bottom plate welding method on the 1st in August in 2012, including following steps：
（1) prefabricated some pieces of center plates, and by forming circular flat bottom storage tank bottom plate after some pieces of center plate tiling docking or overlap joint, and be in be dislocatedly distributed corresponding to the base plate seam between adjacent center plate, then adjacent center plate spot welding is fixed；
（2) annular edge listrium is formed after prefabricated some pieces of scallops balsh plate, then cylindrical tiling by scallop balsh plate along flat storage tank bottom plate, inner ring surface and the outer ring surface of flat storage tank bottom plate of the annular edge listrium match.But its groove tank base plate it is prefabricated in do not account for cutting surplus and welding allowance for shrinkage, do not account for the set-type diameter of tank bottom typesetting figure yet, by intended diameter amplification reserve, the making precision for directly resulting in prefabricated storage tank bottom plate is low so that produce quality problems.
Therefore known benzene hydrogenation engineering there are problems that above-mentioned a variety of inconvenience and.
The content of the invention
The purpose of the present invention, is to propose a kind of method for prefabricating for making large-size stainless steel groove tank base plate under high precision, the hot environment of reliable in quality.
To achieve the above object, technical solution of the invention is：
The method for prefabricating of large-size stainless steel groove tank base plate under a kind of hot environment, it is characterised in that comprise the following steps：
A, the specification according to arrival steel plate, typesetting figure is drawn by design and code requirement to base plate；
B, blanking is carried out according to typesetting figure, to ensure the accuracy of physical dimension, steel plate cutting is cut with semi auto cutting machine；
C, open up groove in strict accordance with the requirement of drawing；
D, negative should carry out preservative treatment in bottom surface.
The method for prefabricating of large-size stainless steel groove tank base plate can also be further achieved by the following technical measures under hot environment of the invention.
Foregoing method, wherein during base plate drafting typesetting figure typesetting in addition to lap width is considered, it is also contemplated that cutting surplus and welding allowance for shrinkage.
Foregoing method, wherein the set-type diameter of the tank bottom typesetting figure, 0.1%~0.15% is amplified by intended diameter.
After adopting the above technical scheme, the method for prefabricating of large-size stainless steel groove tank base plate has advantages below under hot environment of the invention：
1st, making step is reasonable in design, groove tank base plate makes high precision；
2nd, groove tank base plate quality is reliable, be next step assembling creation solid foundation.
Brief description of the drawings
Fig. 1 is the typesetting figure of the stainless steel groove tank base plate of the embodiment of the present invention.
Specific embodiment
With reference to embodiments and its accompanying drawing to the present invention illustrate further.
Embodiment 1
Referring now to Fig. 1, Fig. 1 is the typesetting figure of the stainless steel groove tank base plate of the embodiment of the present invention.
The method for prefabricating of large-size stainless steel groove tank base plate under hot environment of the invention, it is characterised in that comprise the following steps：
A, the specification according to arrival steel plate, typesetting figure is drawn by design and code requirement to base plate；During the base plate drafting typesetting figure typesetting in addition to lap width is considered, it is also contemplated that cutting surplus and welding allowance for shrinkage.The set-type diameter of the tank bottom typesetting figure, 0.1%~0.15% is amplified by intended diameter, and value is 40mm in the present embodiment.
B, blanking is carried out according to typesetting figure, to ensure the accuracy of physical dimension, steel plate cutting is cut with semi auto cutting machine；
C, open up groove in strict accordance with the requirement of drawing；
D, negative should carry out preservative treatment in bottom surface（Except overlapping part）.
The present invention has substantive distinguishing features and significant technological progress, the method for prefabricating making step of large-size stainless steel groove tank base plate is reasonable in design under hot environment of the invention, groove tank base plate makes high precision, reliable in quality, is that solid foundation is created in the assembling of next step groove tank base plate.
Above example is used for illustrative purposes only, rather than limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or change.Therefore, all equivalent technical schemes should also belong to scope of the invention, should be limited by each claim.
