Description

A kind of Flame Heating Temperature compensator for the long weld seam welding of steel plate
Technical field
The utility model relates to for more than thickness 32mm, a kind of Flame Heating Temperature compensator of the steel plate banjo fixing butt jointing submerged arc welding of length 15 ~ 50m.
Background technology
Along with the development of long strands, the steel beam column of Super High, super-span is more and more extensive in the application in construction steel structure field.High-strength steel thick plates has certain tendency of hardenability, overlong welded seam welding procedure is long for interval time, interlayer temperature controls difficult, weld seam cooling is relatively very fast, easily produces weld crack, again due to steel plate overlength, relative rigidity is lower, the welding deformation that the larger temperature difference causes is relatively also comparatively large, and not easily adjustment, high-strength steel slab overlong welded seam fabrication weldability is poor.Therefore effectively improve the problem of high-strength steel slab overlong welded seam fabrication weldability difference, be reduce weld defect, improve the key issue of butt weld flaw detection first-time qualification rate.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of Flame Heating Temperature compensator for the long weld seam welding of steel plate, effectively can solve and improve steel plate overlength welding point fabrication weldability, reduce weld defect, improve the problem of butt weld flaw detection first-time qualification rate.
The technical scheme that the utility model solves comprises reducer pipe, conduit and flame-thrower nozzle, and the big opening end of reducer pipe is connected with suction nozzle, and the osculum end of reducer pipe is equipped with the comb of level through conduit, comb is provided with uniform flame-thrower nozzle.
The diameter of described flame-thrower nozzle is less than the diameter of comb; The diameter of described conduit is less than the diameter of comb.
The utility model novel structure is unique, advantages of simple, easy production, easy to operate, substantially improve steel plate overlength welding point fabrication weldability, reduce weld defect, improve butt weld flaw detection first-time qualification rate, the welding procedure of low-alloy high-strength steel steel plate overlong welded seam can be widely used in, easy to use, effective, there is good economic benefit and social benefit.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Provided by Fig. 1-4, the utility model comprises reducer pipe, conduit and flame-thrower nozzle, and the big opening end of reducer pipe 6 is connected with suction nozzle 8, and the osculum end of reducer pipe 6 is equipped with the comb 2 of level through conduit, comb 2 is provided with uniform flame-thrower nozzle 1.
Shrouding 7 is equipped with for ensureing result of use, the big opening end of described reducer pipe 6, suction nozzle 8 to be fixed on shrouding 7 and with the intracavity inter-connection of reducer pipe 6;
The two ends of described comb 2 are equipped with the support end plate 3 for flat fixed calandria body, fixation respectively, stable;
The diameter of described flame-thrower nozzle 1 is less than the diameter of comb 2; The diameter of described conduit is less than the diameter of comb 2;
Described conduit comprises the first conduit 5 and the second conduit 4 be connected, the inlet end of the first conduit 5 is connected with the osculum end of reducer pipe 6, air inlet on outlet side second conduit 4 sidewall of the first conduit 5 and the intracavity inter-connection of the second conduit, the gas outlet at the two ends of the second conduit is equipped with respectively the comb of level, comb is provided with uniform flame-thrower nozzle 1.
Can clearly be found out by above-mentioned, suction nozzle 8, reducer pipe 6, first conduit 5, second conduit 4, comb 2 and flame-thrower nozzle 1 entirety forms a current path, wherein, flame-thrower nozzle 1 diameter is less than the diameter of comb 2, the diameter of the second conduit 4 is less than the diameter of comb 2, fuel gas enters current path by suction nozzle 8, gas successively logical reducer pipe 6, first conduit 5, second conduit 4, comb 2 sprays from flame-thrower nozzle 1, altogether through three reducings, the stable of flame-thrower nozzle 1 gas vent flow velocity can be guaranteed; During use, overlong welded seam welding adopts the uniform synchronous welding of multiple stage welding machine, each welder technological parameter is identical, welding direction is identical, welding machine is uniform, during welder is advanced, adopt Flame Heating Temperature compensator to follow heating compensation temperature, meet technological requirement to control interlayer temperature, greatly can be apt to the fabrication weldability of steel plate overlong welded seam; Compared with prior art, the utility model novel structure is unique, and advantages of simple, easily produces, easy to operate, substantially improve steel plate overlength welding point fabrication weldability, reduce weld defect, improve butt weld flaw detection first-time qualification rate, the welding procedure of low-alloy high-strength steel steel plate overlong welded seam can be widely used in, easy to use, effective, there is good economic benefit and social benefit.
