Description
The present patent application is divisional application, parent application number：2015108634936；Female case title：A kind of pre- hot charging of welding
It sets and its applies；Parent application day：2015-11-27.
Technical field
The invention belongs to weld preheating technology field, and in particular to a kind of welding preheating device that bolt is adjusted.
Background technology
When welding steel thickness is more than 30mm, often there is the requirement of preheating, i.e., welding portion is first heated before welding
To 100 DEG C, then just start to weld.Preheating step can effectively prevent crackle and the deformation of welding.Existing general use flame adds
Heat, when heating steel sheet thickness is in 100mm or more, it may be desirable to many time can just make steel plate reach defined temperature, and
Energy waste is very big.
In the converter trunnion ring site welding technology of certain steel mill, which is in the site welding technology stage, due to its converter support
It is larger (δ 85mm~δ 130mm) to enclose babinet steel plate thickness, therefore needs to carry out weld preheating.It is pre- before backing ring lower box is welded
It, certainly will be to the backplate surface of backing ring babinet if heating is fixed using conventional backing ring tank surface spot welding round steel when hot
It damages, if heating plate to be directly placed on to the bottom plate lower part of backing ring babinet, since compression degree between the two is also bad
Control, causes the bad control of the preheating temperature of the bottom plate of backing ring babinet.
