Description
Technical field
The present invention relates to a kind of liner plate, a kind of abrasion-resistant alloy steel lining plate.
Background technology
In the powder manufacturing apparatus of mine, electric power and manufacture of cement, liner plate is as main abrasion piece, and year consumption is huge.The lining board of grinder of China's use at present, traditional material is high mangaenese steel ZGMn
13, its initial hardness is HB185～200, can reach HB550 (HRC55.0) through shock peening, dash toughness ak 〉=147J/cm
2, in addition use more general material that rich chromium cast iron KmTBCr is arranged
26, KmTBCr
20Mo
2Cu
1Deng, its hardness is more than the HRC55, impelling strength ak≤8J/cm
2Because material mainly is by steel ball or running roller in grinding machine when revolution cylindrical shell pulverizing with shock action of material to be finished in the grinding machine grinding process, grinding machine mainly bears periodically high all secondary stress, therefore, grinding process can not make high manganese steel lining plate obtain sufficient shock peening, thereby the wear-resisting potentiality of high mangaenese steel can not obtain performance.And as the higher rich chromium cast iron of initial hardness, because impelling strength is low, easy fracture, and because of containing the Cr element up to 20% or higher, and containing precious metal elements such as Mo, Ni, cost is higher, is being difficult to reach requirement aspect economy, the reliability.
Summary of the invention
In order to solve the existing problem of present liner plate, the invention provides a kind of abrasion-resistant alloy steel lining plate.
Above-mentioned technical problem of the present invention is achieved through the following technical solutions:
A kind of abrasion-resistant alloy steel lining plate, chemical ingredients (wt%) is: 0.38%～0.48% C, 0.80%～1.30% Mn, 1.30%～1.80% Si, 1.50%～2.50% Cr, 0.28%～0.38% Mo, S≤0.035%, P≤0.035%, and the Re of trace, all the other are Fe.
A kind of method of making above-mentioned abrasion-resistant alloy steel lining plate, this method may further comprise the steps in regular turn:
A. carry out charge calculation according to chemical ingredients, the furnace charge heat fused of switching on behind the electric furnace of packing into;
B. add alloy material according to the oxidation order;
C. melt post analysis S, P and add molybdenum-iron, 1550 ℃ of oxygen blast of oxidizing temperature add ore;
D. be warming up to 1600 ℃ of backs of skimming and add ferrochrome, make reducing slag and add carbon dust;
E. molten steel is molten skims clearly with tapping after the aluminium block deoxidation, and tapping temperature is 1610 ± 10 ℃;
F. adding tempering by normalizing heat-treats.
A kind of liner plate adopts above-mentioned wear-resisting alloy steel to make.
Compare with prior art, the present invention has following beneficial effect: wear-resisting alloy steel of the present invention has good hardness, intensity and toughness, and its hardness is HRC51～57, impelling strength ak 〉=49J/cm
2, and alloying constituent is lower, and work-ing life is then long than high mangaenese steel, and has better economy and comprehensive mechanical performance than steel manganese steel, rich chromium cast iron.
Embodiment
Below in conjunction with embodiment the present invention is further described.
A kind of abrasion-resistant alloy steel lining plate, its chemical ingredients (wt%) is: 0.38%～0.48% C, 0.80%～1.30% Mn, 1.30%～1.80% Si, 1.50%～2.50% Cr, 0.28%～0.38% Mo, S≤0.035%, P≤0.035%, and the Re of trace, all the other are Fe.
A kind of method of making above-mentioned wear-resisting alloy steel, this method may further comprise the steps in regular turn:
A. carry out charge calculation according to chemical ingredients, furnace charge electric furnace (electric arc furnace or medium-frequency induction furnace) the back energising heat fused of packing into;
B. add alloy material according to the oxidation order;
C. melt post analysis S, P and add molybdenum-iron, 1550 ℃ of oxygen blast of oxidizing temperature add ore;
D. be warming up to 1600 ℃ of backs of skimming and add ferrochrome, make reducing slag and add carbon dust;
E. molten steel is molten skims clearly with tapping after the aluminium block deoxidation, and tapping temperature is 1610 ± 10 ℃;
F. adding tempering by normalizing heat-treats.
The liner plate of using in a kind of powder manufacturing apparatus adopts above-mentioned wear-resisting alloy steel to make.
Experiment showed, that wear-resisting alloy steel of the present invention has good hardness, intensity and toughness, its hardness is HRC 51～57, impelling strength ak 〉=49J/cm
2, and alloying constituent is lower, and work-ing life is then long than high mangaenese steel, and has better economy and comprehensive mechanical performance than high mangaenese steel, rich chromium cast iron.
