Description
Technical field
The invention belongs to weld preheating technology field, and in particular to one kind welding preheating device.
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 welding.Preheating step can effectively prevent crackle and the deformation of welding.Existing general use flame adds
Heat, when heating steel sheet thickness is in more than 100mm, it may be desirable to which 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, the converter trunnion ring is in the site welding technology stage, due to its converter support
Enclose casing steel plate thickness larger (δ 85mm~δ 130mm), therefore need to carry out weld preheating.It is pre- before backing ring lower box is welded
, certainly will be to the backplate surface of backing ring casing if heating is fixed using conventional backing ring tank surface spot welding round steel when hot
Damage, if heating plate to be directly placed on to the bottom plate bottom of backing ring casing, because compression degree between the two is also bad
Control, causes the bad control of preheating temperature of the bottom plate of backing ring casing.
