Abstract
A new type low carbon steel welding wire is composed of welding wire and welding flux, it is characterized in that the welding wire is CIF wire and the welding flux is composed of rutile, reductive ilmenite, mica, sepiolite clay, marble, wood dust, white clay, medium carbon manganese, electrolytic maganese or low carbon manganese, ilmenite. By using new core welding-wire material and welding flux formulation, not only can reach the physical and chemical properties of conventional low carbon steel welding wire, but also the raw material comprehensive cost can be reduced by 10% compared with the low carbon steel welding wire.
Description
The present invention relates to a kind of low carbon steel welding wire, belong to the welding material class.
Common mild steel arc welding electrode (E4303) generally all adopts H08 welding wire and the coating material supporting with it to form at present; Under normal conditions, the coating material that is adopted mainly is by rutile, titanium dioxide, reduced ilmenite, white clay, feldspar, mica, marble, dolomite, medium carbon manganese and wood powder etc.Mild steel arc welding electrode with this traditional core material and coating making, because the cost of its core material and some coating major ingredient has been reduced to the limit, institute thinks makes manufacturer can obtain better economic benefit, and finding new outlets from habitual raw material reduces cost, and has not almost had any possibility.Its only way out is: seek new solder wire material and new coating recipe material.
Purpose of the present invention promptly is: under the prerequisite that guarantees mild steel arc welding electrode physicochemical property and welding performance, seek the combination of a kind of new core wire material and coating recipe, form a kind of low carbon steel welding wire that can keep the low cost of raw material, to guarantee the profit of enterprise.
This low carbon steel welding wire is made up of welding wire and coating, it is characterized in that: described welding wire is the C1F silk; Described coating is made up of rutile, reduced ilmenite, mica, sepiolite clay, illite, marble, wood powder, white clay, medium carbon manganese, ilmenite, electrolytic manganese or low carbon manganese, and the percentage by weight of each composition part is respectively in described coating: 8～28 parts of rutile; 32～40 parts of reduced ilmenites; 0～2 part of sepiolite clay; 4～8 parts of illites; 4～5 parts in marble; 3～4 parts of wood powders; 4～6 parts of white claies; 3～7 parts of medium carbon manganeses; 2～4 parts of electrolytic manganese or low carbon manganeses; 0～30 part of ilmenite.
Described low carbon manganese, its effective ingredient should be more than 80%.
The low carbon steel welding wire of producing according to technique scheme, owing to adopt the C1F welding wire to substitute the H08 welding wire, adopting with low carbon manganese or the electrolytic manganese medium carbon manganese that replace 78% effective content of effective content more than 80% simultaneously again is the coating recipe adjustment of technology contents; Making and adopting the C1F welding wire is this low carbon steel welding wire of core wire, not only kept the physicochemical property and the welding performance of former E4303 mild steel arc welding electrode, but also corresponding 10% the cost of raw material that reduced is guaranteed the profit of manufacturer reliably.
Below provide embodiments of the invention, and further set forth the present invention in conjunction with the embodiments.

In the various embodiments described above, also bamboo powder of the wood powder that adopts.
Below provide the operating position that adopts the mild steel arc welding electrode that C1F welding wire and new combination coating make and with the GB contrast of J422 welding rod.
One, weld metal chemical analysis

Three, C1F welding wire and H08 welding wire are made the contrast of welding rod cost
| The II08 welding wire | The C1F steel wire | II08 silk pressure welding bar | C1F silk pressure welding bar |
| φ 6.5 valencys/ | φ 6.5 valencys | The dry mash cost | The dry mash cost |
| 3200 yuan/ton | 2700 yuan/ton | 2200 yuan/ton | 2250 yuan/ton |
Four, J422 welding rod cost accounting contrast per ton
1, H08 welding wire welding rod welding wire materials: 3200 yuan * 65%=2080 unit dry mash: 2200 yuan * 35%=770 unit totle drilling cost: 2080 yuan+770 yuan=2850 yuan
2, C1F welding wire welding rod welding wire materials: 2700 yuan * 65%=1755 unit dry mash: 2250 yuan * 35%=787.5 unit totle drilling cost: 1755 yuan+787.5 yuan=2542.5 yuan
As seen adopt the C1F welding wire to produce the J422 welding rod and produce welding rod, cost-saved 307.50 yuan per ton than adopting traditional H08 welding wire.
