Description
Technical field
The present invention relates to a kind of liner plate and manufacture method thereof, particularly relate to a kind of tube mill lining board and manufacture method thereof.
Background technology
Tuber grinder is widely used in industries such as cement, mine.Because of being subjected to impact, the ablation of grinding medium and material, the working condition of tube mill lining board is comparatively abominable, so tube mill lining board will have good comprehensive physicalies such as high tenacity and high-wearing feature.Especially for the tube mill lining board of φ more than 3 meters, its requirement to comprehensive physicals such as high tenacity and high-wearing feature is more outstanding.
Except the physicals of tube mill lining board, the manufacturing cost of tube mill lining board also is a very important Consideration in the industry.The employed material of tube mill lining board also has the part ball grinding machine lining board to use alloy steel material to make based on high mangaenese steel simultaneously at present.
Because the initial hardness of high mangaenese steel is lower, so the work hardening of leaning on HI high impact to produce guarantees the wear resistance of high manganese steel lining plate, but the shock peening speed of most of high manganese steel lining plates is lower than its rate of wear, so the wear resistance of high manganese steel lining plate can reduce greatly; And the high mangaenese steel yield strength is low, and in use high manganese steel lining plate easily produces viscous deformation, thereby makes the workpiece lost of life, and causes the dismounting and change difficulty of liner plate.
The steel alloy liner plate, particularly thicker steel alloy liner plate can satisfy the requirement of high rigidity, high tenacity and high-wearing feature, but adds the valuable iron alloy of part mostly in the manufacturing processed of steel alloy liner plate, as add molybdenum-iron more than 0.6% etc., realize the good physical of steel alloy liner plate.Though the physicals of existing steel alloy liner plate has met actual needs to a certain extent, but because it uses precious metal thereby causes the with high costs of existing steel alloy liner plate in castingprocesses, selling price is high, thereby cause the performance and price of steel alloy liner plate lower, be not easy to promote the use of on a large scale.
Summary of the invention
The object of the present invention is to provide a kind of tube mill lining board and manufacture method thereof, when producing, do not use tube mill lining board the steel alloy that contains noble metal, cost is low, and described tube mill lining board hardening capacity is good, has that hardness height, section difference of hardness are little, a good toughness, the excellent characteristics of wear resistance.
To achieve these goals, the invention provides a kind of tube mill lining board, it comprises the component of following weight percent: C:0.35～0.48%, Si:1.5～1.8%, Mn:0.8～1.2%, Cr:1.5～2.5%, S :≤0.035%, P :≤0.035%, RE:0.01～0.05%, B:0.002～0.006%, surplus are Fe.
To achieve these goals, the present invention also provides a kind of manufacture method of tube mill lining board, and it comprises the steps:
(1) chooses each component according to described tube mill lining board desired content, cast this liner plate then;
(2) the described liner plate that will in step (1), cast, oil quenching is handled under 920 ℃～940 ℃ temperature, and the treatment time is 3～6 hours;
(3) to the liner plate temper under 240 ℃～250 ℃ temperature through quench treatment described in the step (2), the treatment time is 10～20 hours.
According to technical conceive of the present invention, employed quenchant is No. 30 machine oil in step (2).
According to technical conceive of the present invention, the time of handling at the described oil quenching of the every increase of the thickness of tube mill lining board described in the step (2) 25mm just increases by 1 hour.
Beneficial effect of the present invention is: tube mill lining board of the present invention adopts medium carbon alloy steel, contain rare earth, silicon, magnesium, boron iso-metamorphism agent going bad processing by adding in the castingprocesses, make particularly wall thickness liner plate of liner plate through proper heat treatment again, not only hardness height, section hardness are even, and good toughness, wear resistance is good, improved the work-ing life of liner plate, reduced cost, the cast properties price is than high, the market competitiveness is strong, has very high practical value.
