Abstract
The present invention relates to an iron base high-chrome cast iron grinding ball which is characterized in that the grinding ball has good wear resistance and good toughness, and comprises the following chemical components of 2.0 to 4.0 wt% of C, 0.3 to 2.0 wt% of Si, 0.4 to 2.5 wt% of Mn, 0 to 0.1 wt% of P, 0 to 0.08 wt% of S, 10 to 25 wt% of Cr, 0 to 1.5 wt% of Mo, 0 to 1.2 wt% of Cu, 0 to 1.4 wt% of W, 0 to 1.0 wt% of V, and Fe as the rest. The grinding ball of the present invention is a novel high-chrome cast iron product, and is applied to ball mills to pulverize various materials of construction material industry, metallurgy ore dressing industry and electric power industry. The iron base high-chrome cast iron grinding ball is applied to large, medium and small cement mills, which proves that the iron base high-chrome cast iron grinding ball has the advantages of no exfoliation, no deformation and no ball breakage, and the ball consumption rate is 2.2 to 50 g/ton cement.
Description
The present invention relates to be used for the rich chromium cast iron of grinding material abrading-ball, particularly relate to a kind of rich chromium cast iron that is used for abrading-ball.
As everyone knows, rich chromium cast iron is a kind of good wear-resistant material that grows up along with the widespread usage of electric furnace the seventies, but because the component of material and consumption design are unreasonable, adopt ordinary sand casting technology again, cause the toughness and the wear resistance of abrading-ball can not reach better fit, not enough and must be in order to remedy abrading-ball wear resistance and flexible through quench hot and temper, to obtain martensitic matrix, but result of use is unsatisfactory, ubiquity abrading-ball early deformation and broken problem, far can not satisfy the service requirements of large-scale cement grinding machine.
In order to overcome the weak point that existing abrading-ball exists, the inventor is through the high cast-iron grinding ball of a kind of novelty of invention after the number of research projects for many years and be used for the rich chromium cast iron of abrading-ball.
The present invention is used for the rich chromium cast iron chemical composition and the consumption following (weight percentage) of abrading-ball:
C 3.2%;Si 1.6%;Mn 2.0%;P 0.05%;S 0.06%;
Cr 15%; Mo 1.0%; Cu 0.8%; W 0.7%; V 0.8%, and all the other are Fe.
Fig. 1 is hardness (HRc, the as cast condition) distribution plan of abrading-ball of the present invention.
Further specify to the following examples of the present invention, rather than restriction the present invention.
Embodiment
The steel material that will contain desirable composition mixes with a certain amount of chromium, molybdenum, copper, vanadium etc., through electrosmelting, when being warming up to about 1600 ℃, makes it fusing, and sampling analysis, and when it reached the chemical ingredients of following weight percent, promptly C 3.2%; Si 1.6%; Mn 2.0%; P 0.05%; S 0.06%; Cr 15%; Mo 1.0%; Cu 0.8%; W 0.7%; V 0.8%, and all the other are Fe, pour into a mould, water 1450 ℃ of temperature, obtained chromium Austria, bainite ten eutectic carbidess through the permanent mold casting mold casting, and obtained the abrading-ball of high rigidity, this hardness of wasting ball is referring to Fig. 1, and Fig. 1 is the hardness distribution (HRc, as cast condition) of three kinds of different diameter abrading-balls.
HI-chrome cast iron for grinding balls of the present invention is used for large, medium and small type cement mill, can obtains good effect, it the results are shown in Table 1.
