Abstract

Be used for a kind of high-speed welding flux that repair at the damaged position of metallurgy industry foundry goods and new foundry goods welds, major technique feature of the present invention is: high-speed welding flux is made up of effective mixed powder, is filled in defective or damaged position, lights with device for igniting, through 40～60 seconds, after 5 minutes burning times.Foundry goods be melted solidify, speed welds together, technology of the present invention is simple, welding is firmly fast, heat energy and mechanical performance with blast furnace molten steel make useless parts regeneration, improve ingot mould service life, save the energy, improve 40 times of work efficiency, be convenient to apply in each big steel mill than manual welding.

Description

High-speed welding flux
Be used for the metallurgy industry foundry goods, big base plate, ingot mould, square slag ladle, novel high-speed welding flux when the repairing at damaged positions such as center cast tube and new foundry goods welding.
Existing salvage of casting technology: to the method that damaged position adopts welding rod to weld more, long to the weld interval of big foundry goods, power consumption is big, and is poisonous, the waste raw material.
The present invention overcomes the prior art deficiency, invented a kind of high-speed welding flux, its principal character is: fast welding flux is made of effective mixed powder, be filled in defective or damaged position, light with device for igniting, through the 40-60 time of second, temperature reaches 1400-1500 ℃, the local foundry goods of rejected region is melted, and welded together by speed.
Concrete prescription of the present invention and welding procedure are finished by following: state the effective material of solder flux by aluminium powder 14% brown iron oxide 77%, accuse stone flour 7%, answer stone 1.6%, and sodium nitrate 0.4%, all % counts by weight, evenly mixes and forms dry powder, its process:
Closely surround with several piece fire insulation brick around the damaged position during welding, at first combustion adjuvant is filled its bottom, thick-layer is 2mm, secondly insert uniform mixed powder above the combustion adjuvant again, its thickness is higher than damaged height 40-50mm, the dry powder that installs is lighted with device for igniting, burning time is 40-60 second, the dry powder ignition temperature is that 1400 degree-1500 are when spending, with local foundry goods fusing around the damaged position, spontaneous combustion is solidified after 5 minutes, and damaged position speed is welded together, residue above removing, as exceed damaged position and can tie with emery wheel.
Embodiment:
The normal welding of burning time (second) temperature (degree)
40 1400-1500 normally weld
50 1400-1500 normally weld
Technology of the present invention is simple, and cost is low, welds the advantages such as fast, firm, has heat energy and the mechanical performance of blast furnace molten steel; Fast welding flux makes useless parts regeneration, improves the service life of ingot mould and saves the energy than 40 times of manual welding raising work efficiency. Be convenient to promote the use of in each big steel mill.

Claims (1)

  1. Being used for a kind of high-speed welding flux that repair at the damaged position of metallurgy industry foundry goods and new foundry goods welds is characterized in that: the effective material of fast welding flux is by aluminium powder 14%, brown iron oxide 77%, accuse stone flour 7%, answer stone 1.6%, sodium nitrate 0.4% evenly mixes forms its process of dry powder (all %) by weight:
