Abstract
The present invention relates to an improvement on hardfacing electrode composition. Said invented hardfacing electrode is made up by uniformly mixing (wt%) high-carbon ferrochrome 40-42.5%, metal chromium 6-8%, medium-carbon ferromangaese iron 1.5-2%, low-carbon ferromanganese iron 1-2%, ferrotitanium 0.8-1.5%, ferromolybdenum 2-3%, ferrovanadium 2-3%, marble 13-15%, fluorite 5-7%, rutile 23.2-25%, quartz 3-6% and soda 0.5-1.0%. Because of integrated action of all ingredients, the service life of said welded layer can be up to 3-4 years, and said invented electrode also possesses the advantages of high hardness, good crack resistance, non-scale welded layer and good weldability.
Description
The present invention relates to the improvement of welding rod composition.
Blower fan is one of the visual plant in power plant, but because the blade of blower fan quick-wearing very under the big working environment of temperature height, fume amount, had a strong impact on the operate as normal of blower fan, and the life-span short (only about 6 months), for improving the anti-wear performance of fan blade, the way of mainly taking at present is the surface overlaying at blade, but the welding rod performance of its use is desirable not to the utmost.
Purpose of the present invention is exactly at the problems referred to above, and a kind of life-span length, high rigidity, hardfacing electrode that welding procedure is good are provided.
The object of the present invention is achieved like this: the present invention gets high carbon ferro-chrome 40-42.5%, crome metal 6-8%, mid-carbon fe-mn 1.5-2%, low-carbon ferromanganese 1-2%, ferrotianium 0.8-1.5%, molybdenum-iron 2-3%, vanadium iron 2-3%, marble 13-15%, fluorite 5-7%, rutile 23.2-25%, quartzy 3-6%, soda ash 0.5-1.0% evenly to mix the back by weight.
High carbon ferro-chrome (carbon containing 6.0-9.0, silicon≤3.0, chromium 〉=60, sulphur≤0.04, phosphorus≤0.04), crome metal (carbon containing≤0.03, chromium 〉=98.5, sulphur≤0.020, phosphorus≤0.010), mid-carbon fe-mn (carbon containing≤1.0, manganese 〉=78, sulphur≤0.020, phosphorus≤0.020), low-carbon ferromanganese (carbon containing≤0.20, manganese 〉=78, sulphur≤0.020, phosphorus≤0.020), ferrotianium (titaniferous 〉=29, carbon≤0.15, sulphur≤0.020, phosphorus≤0.020), vanadium iron (carbon containing≤0.15, sulphur≤0.010, phosphorus≤0.010), molybdenum-iron (carbon containing≤0.15, sulphur≤0.010, phosphorus≤0.010), marble (contains calcium carbide 〉=97, sulphur≤0.020, phosphorus≤0.020), fluorite (fluorinated calcium 〉=95, sulphur≤0.020, phosphorus≤0.020), rutile (contains titanium dioxide 〉=97, sulphur≤0.020, phosphorus 〉=0.020), quartz (contains silica 〉=98, sulphur≤0.020, phosphorus≤0.020), the comprehensive function of soda ash, make the overlay cladding life-span can reach 3-4, high hardness (HR is 55), but also it is good to have crack resistance, overlay cladding does not come off, and welding procedure is good, and (striking is stable, it is few to splash, the removability of slag is good, characteristics such as appearance of weld is attractive in appearance, product of the present invention is also applicable to puddle mixer, the hydraulic turbine, coal pulverizer, the built-up welding of the wearing part of cement machinery and brickmaking machine etc. or reparation.
