Formula and preparing method for rapidly manufacturing cast iron electrodes

Abstract

The invention relates to the technical field of welding consumables, and specifically relates to a formula for rapidly manufacturing cast iron electrodes. A common steel electrode is used as a substrate, flux is applied to the substrate, the flux comprises compositions including, by mass, 80% of iron sesquioxide, 15% of ferroferric oxide and 5% of calcium carbonate. By means of the formula and themanufacturing method for rapidly manufacturing the cast iron electrodes, according to the obtained cast iron electrodes, in the welding process, powder coated on the substrate uses heat of the electrodes to participate in a redox reaction, a core wire of the substrate is oxidized and reduced into materials similar to base metal, and therefore the welding aim is achieved; the manufacturing cast issimple, fast, ready-to-use, low in formula raw material price and easy to purchase and reduces the business capital backlog and the capital cost; and the quality of the cast iron electrodes manufactured according to the manufacturing method in the embodiment is ensured, and the welding quality and effect are ensured.

Description

technical field [0001] The invention relates to the technical field of welding consumables, in particular to a formula and a production method for rapidly producing cast iron welding rods. Background technique [0002] Cast iron welding rods are often used to solve the welding problems of engine shells, covers, machine bases, and cast teeth with wheel breakage, cracks, wear, and punching holes. For example: weld repair on the cast iron module of the stamping die, the weld layer is martensite, and has excellent wear resistance; it is applied to the weld repair of gray cast iron and ductile iron, and has good machining performance, and its strength is twice that of ordinary welding rods; stamping Welding repair on the cast iron module of the mold, the welding layer is martensite, excellent wear resistance; used for the bottom buffer layer, has high strength and high strength, and is used for welding of cast iron, alloy cast iron, steel and cast iron, etc. Therefore, the cost ...

AI Technical Summary

Problems solved by technology

[0003] Existing manufacturers often equip cast iron electrodes for emergency needs, and usually purchase ready-made cast iron electrodes for backup, but the disadvantages of doing so are: first, the cost of cast iron electrodes is several times that of ordinary structural steel electrodes, and the input cost is more. It is a long-term need to stock up for emergencies, resulting in a backlog of corporate funds and increasing capital costs. Third, the quality of cast iron welding rods is mixed, good and bad.
