Abstract
The invention discloses alloy for a cutting bit. The alloy is characterized by containing the ingredients in percentage by mass: 0.60 to 2.22% of carbon, 0.5 to 1.8% of Si, 1.00 to 3.2% of manganese, 0.10 to 0.52% of chromium, 0.07 to 1.9% of titanium, 0.1-0.25% of vanadium, 0.03-0.55% of tungsten, 0.06 to 2.6% of lithium, 0.1 to 1.8% of zinc, 0.24% to 1.5% of rhenium, 0.10 to 0.55% of phosphorus and the balance of ferrum. A cutting bit cutter body made from the alloy has the characteristics of relatively high hardness, good wear resistance, long service life and the like.
Description
Technical field
The present invention relates to a kind of alloy for pick, belong to mining equipment manufacture field.
Background technology
Pick is the key part of coalcutter, is the main tool of coal breakage and broken coal.Adopting pick in process in coalcutter pick acts directly on coal, coal stone or rock, working conditions is severe, require high wear resistance, intensity and good toughness, its performance quality directly affects the work-ing life of the performance of coalcutter throughput, the consumption of power, stable working and other related components.
Summary of the invention
The object of the present invention is to provide a kind of alloy for pick, the cutting pick body using this material to make has the features such as hardness is higher, wear resisting property good, long service life.
The solution of the present invention is as follows: a kind of alloy for pick, and the mass percent of component is: carbon 0.60 ~ 2.22%, silicon 0.5 ~ 1.8%, manganese 1.00 ~ 3.2%, chromium 0.10 ~ 0.52%, titanium 0.07 ~ 1.9%, vanadium 0.1-0.25%, tungsten 0.03-0.55%, lithium 0.06 ~ 2.6%, zinc 0.1 ~ 1.8%, rhenium 0.24 ~ 1.5%, phosphorus 0.10 ~ 0.55%, surplus is iron.
Further, the mass percent of component is: carbon 0.80 ~ 2.22%, silicon 0.6 ~ 1.2%, manganese 1.00 ~ 2.2%, chromium 0.10 ~ 0.32%, titanium 0.07 ~ 1.5%, vanadium 0.1-0.15%, tungsten 0.09-0.35%, lithium 0.06 ~ 1.6%, zinc 0.1 ~ 1.6%, rhenium 0.24 ~ 1.5%, phosphorus 0.10 ~ 0.35%, surplus is iron.
Further, the mass percent of component is: carbon 1.6%, silicon 0.9%, manganese 1.5%, chromium 0.2%, titanium 1%, vanadium 0.15%, tungsten 0.21%, lithium 1.3%, zinc 0.85%, rhenium 1.1%, phosphorus 0..23%, and surplus is iron.
The pick using material produce of the present invention to go out, has following mechanical property: tensile strength: 1200-1600MPa, yield strength: 800-1000MPa, hardness: 50-60HRC.Therefore, use the present invention, the wear resistance of pick, hardness can be improved, increase the service life.
