Abstract
The invention relates to a welding method for a middle shell cover, with a reinforcing ring, of a reforming reactor. The method includes two steps: (1), assembling the reinforcing ring after being blanked with the middle shell cover, leveling and centering the reinforcing ring, adjusting gaps between the reinforcing ring and space around a groove of a central hole of the middle shell cover, controlling the end face of the reinforcing ring to be parallel to a port of the middle shell cover, and welding the reinforcing ring with the middle shell cover; and (2), after leveling and centering a shell ring, installing and welding the middle shell cover with the reinforcing ring with corresponding shell ring, controlling the end face of the reinforcing shell to be parallel to a port of the shell ring; after rounding and centering according to outer surfaces of two ports of the shell ring, processing the end face of the reinforcing ring and the ports of the shell ring, and processing threaded holes around the reinforcing ring. The welding method for a middle shell cover, with the reinforcing ring, of the reforming reactor is convenient to operate and capable of well guaranteeing levelness of the reinforcing ring and verticality of the threaded holes.
Description
Technical field
The present invention relates to the welding method of reforming reactor internals in field of petrochemical industrial, particularly relate to the welding method of the Middle head of reforming reactor band reinforcing ring.
Background technology
Reforming reactor is with space in Middle head partitioned bottle, and there is the reinforcing ring for connecting Middle head and central tube base at Middle head center.Owing to requiring stricter to the perpendicularity of central tube in welding process, so just relatively high to the requirement of the levelness of the influential reinforcing ring of central tube perpendicularity and the perpendicularity of bolt hole, therefore, the welding method of the Middle head of reinforcing ring is with just to seem especially important.
The welding method of the Middle head of existing band reinforcing ring:
First method: after single part manufactures by drawing, then assembly welding by drawing.The method requires very high to assembling, and the levelness of reinforcing ring and the perpendicularity of bolt hole are all difficult to ensure.
Second method: preparatory processing both ends of the surface after reinforcing ring blanking (sealing surface place does not process the i.e. thickness made allowance that puts in place), auger shell keyhole, then with Middle head assembly welding after again with cylindrical shell assembly welding, aft-loaded airfoil reinforcing ring sealing surface to drawing requirement.This method well can ensure the levelness of reinforcing ring, but the perpendicularity of bolt hole is difficult to ensure.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of convenient operation, ensures the welding method of the Middle head of the reforming reactor band reinforcing ring of the levelness of reinforcing ring and the perpendicularity of bolt hole.
For solving the problem, the welding method of the Middle head of reforming reactor band reinforcing ring of the present invention, is characterized in that: the method comprises following two steps:
(1) after reinforcing ring blanking, first assemble with Middle head, by its levelling on platform, centering, the gap of adjustment reinforcing ring and Middle head centre bore groove surrounding, to control reinforcing ring end face parallel with Middle head port, then welded with Middle head by reinforcing ring;
(2), after shell ring is levelling on platform, centering, carry out assembly welding with the Middle head of reinforcing ring and corresponding shell ring, control reinforcing ring end face parallel with shell ring port; Look for circle, centering aft-loaded airfoil reinforcing ring end face and shell ring port according to shell ring two-port outer surface afterwards, finally process reinforcing ring border bolt hole.
Described reinforcing ring blanking should be welded into entirety and smooth when being distinguish blanking.
The present invention compared with prior art has the following advantages:
1, the present invention repeatedly carries out the sealing surface of levelling, centering operation and reinforcing ring and bolt hole is all finally processed, thus well can ensure the levelness of reinforcing ring and the perpendicularity of bolt hole.
2, the present invention is simple to operate and reliability is high.
Detailed description of the invention
The welding method of the Middle head of reforming reactor band reinforcing ring, the method comprises following two steps:
(1) after reinforcing ring blanking, first assemble with Middle head, by its levelling on platform, centering, the gap of adjustment reinforcing ring and Middle head centre bore groove surrounding is to ensure that gap uniformity is consistent, it is parallel with Middle head port to control reinforcing ring end face, then reinforcing ring is welded with Middle head, note during welding preventing welding deformation and postwelding carries out Stress relieving annealing heat treatment;
(2), after shell ring is levelling on platform, centering, carry out assembly welding with the Middle head of reinforcing ring and corresponding shell ring, control reinforcing ring end face parallel with shell ring port, postwelding carries out Stress relieving annealing heat treatment; Look for circle, centering aft-loaded airfoil reinforcing ring end face and shell ring port according to shell ring two-port outer surface afterwards, finally process reinforcing ring border bolt hole.
Should entirety be welded into and smooth during the blanking of reinforcing ring distinguish.
Claims (2)
1. the welding method of the Middle head of reforming reactor band reinforcing ring, is characterized in that: the method comprises following two steps:
(1) after reinforcing ring blanking, first assemble with Middle head, by its levelling on platform, centering, the gap of adjustment reinforcing ring and Middle head centre bore groove surrounding, to control reinforcing ring end face parallel with Middle head port, then welded with Middle head by reinforcing ring;
(2), after shell ring is levelling on platform, centering, carry out assembly welding with the Middle head of reinforcing ring and corresponding shell ring, control reinforcing ring end face parallel with shell ring port; Look for circle, centering aft-loaded airfoil reinforcing ring end face and shell ring port according to shell ring two-port outer surface afterwards, finally process reinforcing ring border bolt hole.
2. the welding method of the Middle head of reforming reactor band reinforcing ring as claimed in claim 1, is characterized in that: should be welded into entirety and smooth when described reinforcing ring blanking is distinguish blanking.
