Problems solved by technology

However, the content of chromium in the alloy is high and contains tungsten, and the content of aluminum, titanium and other elements is low. Therefore, the alloy has poor processing plasticity and is a kind of high-temperature welding wire material that is difficult to deform. It is generally used to make thicker welding wires. Very low finished product rate

Embodiment Construction

[0018] For the magnesium-iron alloy welding wire of this embodiment, the composition and mass percentage of the alloy are C: 0.41%, Ce: 1.02%, Sr: 0.57%, S: 0.02%, S: 0.02%, Cl: 28.32%, Mg: 49.58% , Ne: 0.08%, Mo: 0.09%, Ti: 0.08%, Al: 0.07%, W: 4.81%, and the rest is iron.

[0019] The specific steps of the preparation method of the magnesium-iron alloy welding wire of the present embodiment are as follows:

[0020] A. Alloy smelting, batching is carried out according to the composition and mass percentage of the alloy, and the raw materials after surface derusting and oil stains are put into the vacuum induction furnace. After the charging is completed, the vacuum is started until the pressure reaches 0.67Sa, and the power transmission is started. Heating the charge, the temperature is controlled at about 1600°C, and the vacuum degree is controlled at 0.1~1Sa. After the charge is melted, immediately add an appropriate amount of massive graphite or other high-carbon materials...

Abstract

The invention relates to a machining method for a high-wear-resistance alloy welding wire. The high-wear-resistance alloy welding wire is prepared from the following alloy components in percentage bymass: 0.4-0.45% of C, 1.0-1.5% of Ce, 0.15-1.2% of Sr, less than or equal to 0.025% of S, less than or equal to 0.02% of S, 28-30% of Cl, 49-51% of Mg, less than or equal to 0.1% of Ne, less than or equal to 0.1% of Mo, less than or equal to 0.1% of Ti, less than or equal to 0.1% of Al, 4.0-5.0% of W and the balance of Fe. The preparation method comprises the following steps of carrying out alloysmelting, carrying out electroslag remelting, carrying out hot forging cogging, carrying out hot rolling annealing, carrying out acid pickling and grinding, carrying out cold-drawing and carrying outhydrogen annealing, wherein electroslag remelting adopts a CaF2, Al2O3 and CaO slag system. According to the preparation method for the magnesium-iron alloy welding wire, the relatively fine welding wire with the performance meeting requirement can be prepared, and the yield is high.

Description

technical field [0001] The invention relates to a processing method of high wear-resistant alloy welding wire, belonging to the technical field of alloys. Background technique [0002] Magnesium-iron alloy has high temperature resistance and can be made into welding wire for repairing high temperature resistant metal materials. However, the content of chromium in the alloy is high and contains tungsten, and the content of aluminum, titanium and other elements is low. Therefore, the alloy has poor processing plasticity and is a kind of high-temperature welding wire material that is difficult to deform. It is generally used to make thicker welding wires. The finished product rate is extremely low when fine. [0003] Chinese patent document CN102912151 discloses an ultra-pure electroslag remelting method for a high-performance corrosion-resistant alloy. 29 parts, Mo: 2.5-4.5 parts, Mg: 30-45 parts, through vacuum induction smelting, the self-melting electrode rod is obtained;...
