Description
Technical field
The utility model relates to a kind of auxiliary welding tools, and in particular to disk outstanding greatly welds in a kind of converter connecting apparatus
Heating and thermal insulation ring.
Background technique
Pneumatic steelmaking is the essential smelting link of modern steel enterprise, in converter smelting equipment, converter body with
The attachment device of towing loop is can be closely joined together furnace body with towing loop and the important machine of the various modifications of furnace body
Tool device.Spherical hinge slide bar attachment device is the relatively good converter connecting apparatus of effect, and disk outstanding greatly therein needs to be welded to converter
On furnace body, since entire attachment device is for the importance of converter system, so the welding quality of disk outstanding greatly is most important.In order to
Guarantee welding quality, needs the welding position to big outstanding disk and converter body to heat before welding, weld seam needs slow after welding
Slow cool down is to room temperature, and to guarantee weld seam crystal quality, and disk outstanding greatly is circular ring structure, and is radially set centainly in outer ring
Quantity reinforcing rib, since its size is larger, Heat artificially cannot be guaranteed the synchronism of heating, need quantity with electric heating wire heating
It is more, higher cost, so suitable weld heating attemperator is needed to carry out weld heating and heat preservation to big outstanding disk.
Utility model content
The purpose of the utility model is to provide disk weld heating insulating ring outstanding greatly in a kind of converter connecting apparatus, the devices
It is evenly heated before being able to achieve welding and postweld heat preservation, install convenient is at low cost.
The technical scheme adopted by the utility model is
Disk weld heating insulating ring outstanding greatly in a kind of converter connecting apparatus is greater than the hollow of big outstanding dish external diameter including internal diameter
Annulus, several along hollow circular ring inside circumference uniformly distributed straight tube burner, the air inlet that is connect with hollow circular ring outer circumference
Straight tube, several be located at hollow circular ring with side end face and for the fixation bracket that is mounted on converter shell, straight tube burner
It is directed to the hollow circular ring center of circle and is connected to hollow circular ring, air inlet straight tube is directed toward the hollow circular ring center of circle and connects with hollow circular ring
Logical, fixed bracket is not connected to hollow circular ring, and air inlet straight tube is connected to the coal gas source at converter scene by gas pipe.
Preferably, fixed bracket is symmetrical about straight line where air inlet straight tube.
Preferably, hollow circular ring, air inlet straight tube and fixed bracket are all made of aluminium alloy, and straight tube burner uses resistance to heat seal
Gold.
The beneficial effects of the utility model are:
1. the device is mounted on converter shell by fixed bracket, it is located in the periphery of big outstanding disk, install convenient；
When work, by air inlet straight tube into coal gas, hollow circular ring distributes coal gas, and the flame of straight tube burner can be directly to big outstanding disk
Annulus weld (reinforcing rib root) is toasted, and heating and postweld heat preservation before uniform welding are carried out；Equally distributed straight tube
Burner can be formed with the reinforcing rib in big outstanding disk and be misplaced, and not influence work；Coal gas is largely generated by converter smelting, cost
It is low.
2. converter shell is substantially that circumference is symmetrical, fixed bracket uses symmetry arrangement, fixed steady, easy for installation.
Detailed description of the invention
Fig. 1 is the perspective view of the utility model embodiment.
Fig. 2 is the front view of Fig. 1.
Fig. 3 is the sectional view in Fig. 2 at A-A.
In figure: 1- hollow circular ring；2- straight tube burner；3- air inlet straight tube；4- fixes bracket.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1 to Figure 3, disk outstanding greatly is greater than with weld heating insulating ring, including internal diameter in a kind of converter connecting apparatus
The hollow circular ring 1 of big outstanding dish external diameter, several along the uniformly distributed straight tube burner 2 of 1 inside circumference of hollow circular ring, with hollow circular ring 1
The air inlet straight tube 3 of outer circumference connection, several be located at hollow circular ring 1 with side end face and for being mounted on converter shell
Fixation bracket 4, straight tube burner 2 is directed to 1 center of circle of hollow circular ring and is connected to hollow circular ring 1, and air inlet straight tube 3 is directed toward
It 1 center of circle of hollow circular ring and is connected to hollow circular ring 1, fixed bracket 4 is not connected to hollow circular ring 1, and air inlet straight tube 3 passes through coal gas
Pipe is connected to the coal gas source at converter scene.The device passes through fixed bracket 4 and is mounted on converter shell, is located in the circle of big outstanding disk
All outsides, install convenient；When work, by air inlet straight tube 3 into coal gas, hollow circular ring 1 distributes coal gas, the fire of straight tube burner 2
Flame can directly toast the big annulus weld (reinforcing rib root) for hanging disk, and progress is heated before uniformly welding and postwelding
Heat preservation；Equally distributed straight tube burner 2 can be formed with the reinforcing rib in big outstanding disk and be misplaced, and not influence work；Coal gas is by turning
Furnace smelts a large amount of generations, at low cost.
As shown in Figure 1, in the present embodiment, fixed bracket 4 is symmetrical about 3 place straight line of air inlet straight tube.Converter
Furnace shell is substantially that circumference is symmetrical, and fixed bracket 4 uses symmetry arrangement, fixed steady, easy for installation.
In the present embodiment, hollow circular ring 1, air inlet straight tube 3 and fixed bracket 4 are all made of aluminium alloy, mitigate gross weight, directly
Pipe burner 2 uses heat-resisting alloy, enhances service life.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations all should belong to the protection scope of the appended claims for the utility model.
