Abstract
The invention discloses a carbon steel welding electrode special for steel for boilers and pressure vessels, with low-hydrogen coating. The welding electrode is characterized in that the coating of the welding electrode is prepared from the following components by weight: 30-40% of marbles, 20-30% of fluorites, 5-10% of low carbon ferromanganese, 8-15% of quartz, 10-15% of rutile, 4-16% of ferrous powder, 8-16% of ferrosilicon, 0.5-1.5% of CMC and 0.8-1.6% of sodium carbonate. The welding electrode is formed by selecting and adjusting the materials. The coating of the welding electrode is mainly protected by slag, and the satisfactory deposited metal performance is obtained by adjusting the components and the alloy materials in the coating.
Description
Affiliated technical field
The invention belongs to the flux material field, relate to a kind of boiler of hydrogen controlled covering, carbon steel welding electrode special of steels for pressure vessel use of being applicable to.
Background technology
Along with the development of society, more and more higher to the specification requirement of welding rod product.In the prior art, as E5015 type carbon steel welding electrode, its main alloy system does not satisfy its requirement under condition of heat treatment.The present invention is a 50KG level welding rod, and intensity will satisfy the requirement of 50KG level under as-welded and condition of heat treatment, and the selected and adjustment by to batching is optimized combination to prescription, obtains good welding procedure and deposited metal performance.
Summary of the invention
In order to satisfy various requirement, the invention provides a kind of boiler, steels for pressure vessel use carbon steel welding electrode special of low hydrogen type pharmacopoeia skin, this welding rod can reach the requirement of 50KG level simultaneously under as-welded and condition of heat treatment.
The present invention solves the technical method that its technical problem takes: by analyzing and the characteristic of research material, through proportioning test repeatedly, the chemical coating of welding electrode prescription (in weight proportion) of selected employing is: 30-40, fluorite 20-30, the violent iron 5-10 of low-carbon (LC), quartzy 8-15, rutile 10-15, iron powder 4-16, ferrosilicon 8-16, CMC 0.5-1.5, soda ash 0.8-1.6 are closed in Dali.Be mixed into welding rod crust spice by said ratio, add waterglass or other binders, be coated in HO8A special-purpose steel core wire or other high-quality steel core wires become welding rod through electrode extrusion press, drying typing again is made for the welding rod that diameter is all sizes such as 2.5CM, 3.2CM, 4.0CM, 5.0CM.
The present invention is a welding rod of material being matched, adjusted composition.Electrode coating of the present invention is mainly done protection with slag, by component and alloy material in the adjustment coating, thereby obtains satisfied deposited metal performance.
Show through test of many times, this product have splash less, moulding is attractive in appearance, it is easy to take off slag, can carry out all-position welding.
The specific embodiment
The embodiment of the invention:
| Material name | Prescription one | Prescription two |
| Marble | 32 | 30 |
| Fluorite | 25 | 22 |
| Rutile | 10 | 12 |
| Quartzy | 10 | 8 |
| Low-carbon ferromanganese | 8 | 8 |
| CMC | 1 | 1 |
| Iron powder | 5 | 10 |
| Soda ash | 1 | 1 |
| Ferrosilicon | 8 | 8 |
By above-mentioned chemical coating of welding electrode proportioning, spice added on request add the waterglass binder in the mixer again and stir, the group of making joins after extrusion press is coated in the special-purpose core wire of HO8A again, enters dryer baking typing, after test package, make the welding rod of different size.
