Abstract
The utility model discloses a hole-shaped composite lining board for a mill. The utility model is composed of a basal body (1) and a conical bar (2), wherein, the basal body (1) is cast into the hole-shaped lining board by alloy steel; the conical bar (2) is cast by wear resistant mediums, the dimension of the conical bar (2) is matched with the hole shape of the basal body (1), and the conical bar (2) is inserted into the hole of the basal body (1) by mechanical composites. The utility model has the advantages of favorable wearability, strong toughness, long service life, advanced technology, high rate of finished products, low manufacturing cost, valuable alloy saving and energy saving, the utility model is an ideal lining board for a mill, and is especially suitable for mine industry, metallurgy industry, electric power industry, building material industry, etc.
Description
The utility model relates to the machinery in general fragmentation, grinding or the field of pulverizing, the composite liner that particularly a kind of grinding machine is used.
Ball mill is the powder process machinery of industrial extensive uses such as smelting, mine, electric power, building materials.Lining board of grinder is the main wear-out part in the ball mill.According to statistics, the annual all size liner plate that consumes in the whole nation reaches more than 60,000 tons expensive about 500,000,000 yuan.A large amount of metal materials is not only wasted in the consumption of liner plate, and has a strong impact on the quality of powder process.
Common liner plate is divided into two big classes both at home and abroad at present: a class is the homogenous material liner plate, and a class is the liner plate of composite.Traditional high manganese steel lining plate, anti-wear performance is poor, and service life is short; High chrome lining poor toughness, using under the wet-milling operating mode does not have advantage, uses to be restricted in big grinding machine and power industry.Traditional composite liner has biliquid cast, powder sintering.Because biliquid pouring technology complexity, yield rate is low; And the compound composite thickness of powder is very little, is unsuitable for industries such as mine, metallurgy, electric power, building materials and uses.Chinese patent CN91225460.2 discloses a kind of grinding machine duplex metal composite lining board, and it is made up of matrix and tooth bar, adopts the alloying method that liner plate matrix and tooth bar two parts are cast for an integral body.Advantage is the wearability and the service life of improving high manganese steel lining plate.Weak point is a complex process, the production cost height, and yield rate is low.
The purpose of this utility model is to develop a kind of existing excellent wear and has fine obdurability, long service life, technology advanced person, yield rate height again, the hole shape composite liner that production cost is low.
To achieve these goals, solution of the present utility model is: the hole shape composite liner is made up of matrix (1) and circular cone rod (2).Matrix (1) pours into the hole shape liner plate with alloy steel material, and circular cone rod (2) adopts the wear-resistant material manufacturing, and the hole shape of the size of this circular cone rod (2) and matrix (1) is complementary, and adopts machinery compound in the hole of circular cone rod (2) embedding matrix (1).
During matrix (1) adopts, low-alloy steel or potassium steel makes, circular cone rod (2) adopts rich chromium cast iron series, carbide alloy, general white cast-iron, low chromium white cast iron, ceramic material or KMTBCr28 series.
The utility model compared with prior art has following advantage:
(1) toughness height, anti-wear performance are good.Increase the service life, production technology advanced person, yield rate height, production cost are low.
(2) the circular cone rod can adopt nonmetal wear-resistant material, as cast stone, pottery, has both improved the liner plate wearability, saves valuable alloy again, and alleviates ball grinding machine lining board weight, energy savings greatly, remarkable in economical benefits.
Below in conjunction with accompanying drawing the utility model is described in further detail.

Embodiment:
With rich chromium cast iron series (or carbide alloy, general white cast-iron, low chromium white cast iron, ceramic material, KMTBCr28 series), casting circular cone rod (2); With potassium steel (or in, low-alloy steel), adopt disappearance mould process for suction casting, the hole shape liner plate of casting matrix (1), the hole shape of the size of circular cone rod (2) and matrix (1) is complementary.Circular cone rod (2) is after foundryman's fever is handled, and employing machinery is compound to be embedded in circular cone rod (2) in the hole of matrix (1).Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4.
Claims (2)
1. grinding machine hole shape composite liner, it is characterized in that it is made up of matrix (1) and circular cone rod (2), matrix (1) is cast as the hole shape liner plate with steel alloy, circular cone rod (2) is selected the wear-resistant material casting for use, the hole shape of the size of this circular cone rod (2) and matrix (1) is complementary, and adopts machinery compound in the hole of circular cone rod (2) embedding matrix (1).
2. composite liner according to claim 1, it is characterized in that matrix (1) adopt in, low-alloy steel or potassium steel, circular cone rod (2) adopts rich chromium cast iron series, carbide alloy, general white cast-iron, low chromium white cast iron, ceramic material or KMTBCr28 series.
