Abstract
The invention relates to a ferrosteel welding technique and self-fusion welding powder technique, wherein said method comprises that: 1, cleaning the defect part, oily dirt and oxidized skin at 30mm around; 2, brushing air agent at the defect part; 3, using prepared self-fusion welding powder to cover the defect; 4, heating around base material at high temperature to burn the welding powder to fuse the welding powder and base material. Said air agent is solvent mainly formed by alkali oxide. And the welding powder comprises aluminum powder at 30-45%; carbon powder at 6-10%; silicon iron powder at 10-14%; titanium iron powder at 9-12% and the left is cast iron powder.
Description
Technical field:
What the present invention relates to is grey cast-iron welding procedure and material, and especially a kind of grey cast-iron soldering is with melting homogeneity welding powder and process for welding repair certainly.
Background technology:
In the prior art, technique known is disclosed No. 200510096376.8 patent applications of State Intellectual Property Office, this patent application discloses a kind of technical scheme that is used for the homogeneity welding rod/torch welding rods fabricated of casting pig and Nodular Iron Welding, this scheme, can realize at ambient temperature grey cast-iron being welded, and can reduce spoken parts in traditional operas and crackle tendency effectively, composition of weld line, tissue and color and luster and foundry goods basically identical, but the constituent complexity of this scheme, needing to be processed into welding wire again could use, and this is the existing in prior technology weak point.
Summary of the invention:
Purpose of the present invention is exactly at the existing in prior technology deficiency, and provide a kind of grey cast-iron soldering to use from the technical scheme that melts homogeneity welding powder and process for welding repair, this scheme adopts simple proportioning to form from molten homogeneity welding powder, use simple process for welding repair, utilize the soldering of the temperature realization of welding powder spontaneous combustion, can reach at room temperature and operate, do not occur the crisp sclerous tissues of spoken parts in traditional operas in the fusion area the grey casting defective, and, the color of soldering place and mother metal color basically identical.
This programme is realized by following technical measures:
The grey cast-iron soldering is with from molten homogeneity welding powder, its welding powder component consisting of by weight: aluminium powder: 30-45%; Carbon dust: 6-10%; Ferrosilicon powder: 10-14%; Titanium-iron powder: 9-12%; All the other are the homogeneity cast iron powder.
The process for welding repair of grey cast-iron from molten homogeneity welding powder:
The first step: greasy dirt and oxide skin in cleaning casting iron defect position and 30 millimeters scopes of periphery;
Second step: brush the gas agent at the casting iron defect position;
The 3rd step: cover the fault location that has been coated with the gas agent with the molten certainly homogeneity welding powder for preparing;
The 4th step:, make from molten homogeneity welding powder and burn from molten homogeneity welding powder periphery mother metal with high temperature heating, utilize the temperature of welding powder spontaneous combustion that welding powder and mother metal are melted simultaneously and carry out soldering.
Described gas agent is to be the main flux of forming with basic anhydride.
The beneficial effect of this programme can learn according to the narration to such scheme, owing in the molten certainly homogeneity welding powder that this scheme is used, contain aluminium powder, the main effect of aluminium powder is the ignition quality that utilizes it, when its spontaneous combustion, welding powder and mother metal can be fused simultaneously and is integral; The effect of institute's carbonaceous powder is the scaling loss that is used for replenishing the mother metal carbon, and promotes graphitization to carry out; The effect of contained ferrosilicon powder is a crystal grain thinning, also promotes graphitization to carry out simultaneously; The effect of contained titanium-iron powder is deoxidation and crystal grain thinning; The homogeneity cast iron powder then is identical with the mother metal composition in order to guarantee, is the main component of replenishing casting defect.The gas agent that this programme adopted is to be used for removing that the viscosity of silica generation in the welding is big, fusing point is high, the silica (SiO of poor mobile performance
2).This scheme is to have adopted simple proportioning to form from molten homogeneity welding powder, use simple process for welding repair, utilize the soldering of the temperature realization of welding powder spontaneous combustion to the grey casting defective, can reach at room temperature and operate, the crisp sclerous tissues of spoken parts in traditional operas does not appear in the fusion area, and, the material behavior of the material behavior of soldering place and color and mother metal and color basically identical.
