Description
Technical field
The present invention relates to technical field of welding materials, specifically a kind of high-chromium wear-resistant manual build up welding welding rod.
Background technology
In recent years, in process of producing product and actual application, to mechanical part performance, such as surface strength, wearability, corrosion resistance propose higher requirement.Built-up welding is quick process as a kind of economic of material surface modifying, is applied to more and more widely during the manufacture of each industrial department part repairs.Wearability and the corrosivity of existing electric welding rod for built-up welding are the most less desirable, cause reaching intended welding effect.
Summary of the invention
For solving the problems referred to above, the present invention provides a kind of high-chromium wear-resistant manual build up welding welding rod, it is easy to built-up welding, and with low cost, and welding rod wearability is good, and corrosion resistance is strong.
The technical solution used in the present invention is: a kind of high-chromium wear-resistant corrosion-resistant manual build up welding welding rod, and described welding rod includes the component of following weight portion: ferrosilicon 1-3 part, ferrochrome 30-40 part, molybdenum-iron 2-5 part, nikel powder 1-2 part, ferrotungsten 1-2 part, ferromanganese 1-5 part, ferro-boron 0.5-2 part, ferro-niobium
8-15 part, ferrotianium 0.6-2 part, titanium dioxide 1-2 part, rare earth alloy 1-2 part.
Preferably, described welding rod includes the component of following weight portion: ferrosilicon 1-2 part, ferrochrome 35-40 parts, molybdenum-iron 3-4 part, nikel powder 1-2 part, ferrotungsten 1-2 part, ferromanganese 2-4 part, ferro-boron 0.5-1 part, ferro-niobium 8-10 part, ferrotianium 1-2 part, titanium dioxide 1-1.5 part, rare earth alloy 2 parts.
Preferably, in described ferrochrome, the content of chromium is 70%.
The invention has the beneficial effects as follows: chromium element improves anti-corrosion, heat-resisting, non-oxidizability and the cracking resistance of welding rod；Boron element can improve compactness and the hot rolling performance of welding rod, improves welding rod intensity；Niobium element energy crystal grain thinning, improving welding property, prevent intercrystalline corrosion phenomenon, improve resistant to hydrogen, nitrogen, ammonia corrosion ability under weather-resistant and high temperature；Molybdenum element, except energy crystal grain thinning, also can improve quenching degree, thermostrength and creep resisting ability；Rare earth alloy can participate in redox reaction during welding, crystal grain thinning, increases crack resistance, toughness and plasticity.In a word, this welding rod prescription proportioning is scientific and reasonable, it is easy to built-up welding, and with low cost, and welding rod wearability is good, and corrosion resistance is strong.
