Abstract
The invention relates to a roller machine used abrasion resistant building up core welding wire, featuring in the pure gold stuffed in the steel belt or alloy material and weight proportion, ensuring the component proportion like this: C 0. 6-1. 8%, Si 1. 0-2. 5%, Mn 0. 5-1. 5%, Cr 5-10%, Nb 3-10%, Mo 0-1. 5%, Ti 0-0. 5%, V 0-0. 5%.
Description
Technical field
The present invention relates to a kind of abrasion-proof pile-up welding flux-cored wire for roll squeezer, it belongs to field of welding material, mainly be to use it as hardfacing materials, adopt the mode of submerged arc overlay welding especially forming wearable overlay on the roll squeezer of cement industry on the component surface, improve parts service life.
Background technology
The phenomenon that whole machinery can't be used prematurely owing to the wearing and tearing of parts is very extensive, and the protection of material becomes more and more important.Any method or material that can alleviate wearing and tearing can produce considerable economic.Need improve the occasion of wearability to increase the service life at parts, best solution is to use wearing face at the core piece surface of cheap and good toughness.In most of available process of surface treatment,, adopt the flux-cored wire hard-face overlaying welding to become the most general technology thereby make because the adjustment of flux-cored wire composition is quite convenient.
The manufacturing process of flux-cored wire relates to the mixing of various powder, and mixed-powder is dosed in the metal sheath with definite shape subsequently, pulls to final size and coiling subsequently.In the processing performance and serviceability of flux-cored wire, the composition of alloy or metal dust and proportioning are quite important in the medicine core, and another key factor that needs aborning to control is a filling rate.
Mainly contain rich chromium cast iron class, tungsten carbide class in the at present general wear-resistant material wearing and tearing flux-cored wire material, contain three kinds of the resurfacing welding materials of TiC.
The general chemical composition such as the table 1 of rich chromium cast iron class resurfacing welding material.
The general chemical composition of table 1 rich chromium cast iron class resurfacing welding material

| MKO606 | 4～6 | 1～2 | 1～2 | 21～34 | 7 | 7 | 2 | 1 | 63 |
The main chemical compositions such as the table 2 of tungsten carbide class resurfacing welding material.
The main chemical compositions of table 2 tungsten carbide class resurfacing welding material
| WC | Cr, Si, Mn, Mo, Ni etc. | Fe | HRC |
| 40～60 | Surplus | 57 | |
| 40～60 | 2～8 | Surplus | 60 |
The chemical composition that contains the resurfacing welding material of TiC is:
C 1.8％，Si 0.7％，Mn 1.2％，Cr 6.5％，Mo 0.8％，Ti 5.0％，V 0.2％。
The overlay cladding wear-resistant material abrasiveness of preceding two kinds of materials is fine, but the stress release crackle can occur inevitably in weld deposit process, like this, just can not use under the working condition that requires to bear than big pressure, on the roll squeezer as cement plant raw material and grog.Though a kind of material stress release crackle in back is few, overlay cladding can not carry out machined.In the process that built-up welding is repaired, must remove original overlay cladding sometimes in order to continue built-up welding, the existence of this resurfacing welding material has just increased difficulty, even causes and can not remove fully, and has further influenced the service life after the built-up welding.
The advantage of material of the present invention is the hardness height, and HRC can reach more than 60, and wearability is good, the multiple-bead deposit flawless, and machinability is arranged, can process with tungsten carbide or sintex.
The present invention realizes by following manner:
Select suitable metal or alloy powdery components and proportioning, mix various powder, then the powder that mixes is dosed in the steel band (generally being " U " shape) with definite shape, make it joint close,, reach suitable dimensions then by drawing by milling train.
Raw-material selection can be the alloy powder that contains various elements, as ferrochrome, and ferrosilicon, ferromanganese, ferro-niobium, molybdenum-iron, ferrotianium, vanadium iron, graphite etc. can be pure metal powders also, as chromium powder, silica flour, manganese powder, niobium powder, molybdenum powder, titanium valve, vanadium iron, graphite etc.When adopting alloy powder, need be converted into the amount of simple metal by purity.Filling rate (percentage of medicine core weight station welding wire weight) is between 10%～40%.
Welding wire of the present invention can well be applied to can carry out the on-the-spot built-up welding reparation in the workshop built-up welding manufacturing and cement plant on the roll squeezer of industry such as cement, surpasses material in the past service life.
Welding wire of the present invention mainly is to adopt the submerged arc overlay welding mode, cooperates alkaline solder flux to use.Also can be used for the open arc built-up welding.
