Abstract
The utility model relates to a deep crack welding structure of a tool withdrawal groove of a rolling mill stand casting. The deep crack welding structure is characterized in that the rolling mill stand casting is included, a rectangular through groove is formed in the rolling mill stand casting, the tool withdrawal groove is casted in at a corner of the rectangular through groove, a V-shaped through hole is cut in a crack position of the tool withdrawal groove, round steel is welded in the V-shaped through groove, and besides the round steel, welding flux is overlaid in the V-shaped through groove. According to the deep crack welding structure of the tool withdrawal groove of the rolling mill stand casting, the round steel is welded in the V-shaped through groove, and besides the round steel, the welding flux is overlaid in the V-shaped through groove, so that the problem of continuous cracking of a deep crack is thoroughly solved.
Description
technical field:
The utility model relates to a kind of rolling-mill housing foundry goods depth of recess crack welding and repairing structure.
background technology:
Current rolling-mill housing foundry goods, for fear of machined escape before processing rectangular through slot, can before casting rolling-mill housing foundry goods, on the turning in rectangular through slot, directly cast out escape, but often this escape place there will be the crackle of penetrability, thereby affect the quality of product, and general soldering cannot better address this problem.
summary of the invention:
The purpose of this utility model is to provide a kind of rolling-mill housing foundry goods depth of recess crack welding and repairing structure, and this rolling-mill housing foundry goods depth of recess crack welding and repairing reasonable in design, is conducive to solve the problem that through wall flaw appears in foundry goods escape.
The utility model rolling-mill housing foundry goods depth of recess crack welding and repairing structure, it is characterized in that: comprise rolling-mill housing foundry goods, described rolling-mill housing foundry goods is provided with rectangular through slot, the turning of described rectangular through slot is cast with escape, cracks at escape is cut with V-type through slot, in V-type through slot, be welded with round steel, in described V-type groove, except round steel, heap is welded with scolder.
The length of above-mentioned round steel connects whole V-type through slot.
The cross section of above-mentioned escape is the through slot of major arc shape.
The utility model rolling-mill housing foundry goods depth of recess crack welding and repairing structure is by be welded with round steel in V-type through slot, and in V-type groove, except round steel, also heap is welded with scolder, has thoroughly solved the problem that degree of depth crackle continues to split.
accompanying drawing explanation:
Fig. 1 is the organigram of rolling-mill housing foundry goods;
Fig. 2 is the K portion zoomed-in view of Fig. 1;
Fig. 3 is the utility model crack welding and repairing structural representation.
the specific embodiment:
The utility model rolling-mill housing foundry goods depth of recess crack welding and repairing structure, comprise rolling-mill housing foundry goods 1, described rolling-mill housing foundry goods is provided with rectangular through slot 2, the turning of described rectangular through slot 2 is cast with escape 3, cracks 4 at escape is cut with V-type through slot 5, in V-type through slot, be welded with round steel 6, in described V-type groove, except round steel, heap is welded with scolder 7.
This round steel can be reinforcing rod.Scolder is the scolder that melting welding is used, and has generally included core wire and coating, and core wire is metal material, not only as the electrode of welding use, also as the material of built-up welding.
For easy to process, increase fastness, the length of above-mentioned round steel connects whole V-type through slot.
For reasonable in design, the cross section of above-mentioned escape is the through slot of major arc shape.
The utility model rolling-mill housing foundry goods depth of recess crack welding and repairing structure is by be welded with round steel in V-type through slot, and in V-type groove, except round steel, also heap is welded with scolder, has thoroughly solved the problem that degree of depth crackle continues to split.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
