Description
Technical field
The present invention relates to a kind of liner plate, the extraordinary composite liner of ceramic-steel iron.
Background technology
Equipment such as the hopper in the industry feeding system, hopper improve service life for preventing the apparatus body wearing and tearing, all at the position of materials flow process abrasion-proof backing block are set.The material of abrasion-proof backing block employing at present has cast steel liner plate, rubber ceramic composite lining board or the like, and the impact resistance of cast steel liner plate and anti-vibration resistance are good, be not easy fragmentation and come off, but its anti-wear performance is relatively poor, and cost is also higher; The rubber ceramic composite lining board is a ceramic embedded plate on rubber, is characterized in that anti-wear performance is good, and cost is lower, but impact resistance and anti-vibration resistance are poor, and heatproof not.Ceramic wafer comes off from rubber slab easily.At the problems referred to above, the applicant has developed the extraordinary composite liner of a kind of ceramic-steel iron, to improve the combination property of liner plate.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of extraordinary composite liner of ceramic-steel iron of good combination property.
The technical solution adopted for the present invention to solve the technical problems is:
The extraordinary composite liner of ceramic-steel iron is characterized in that it comprises metal backing, by casting or founding technology special ceramic block is cast in the metal backing in the described metal backing, and special ceramic block and metal backing merge in aggregates.
The special ceramic block that the present invention adopts is to form at 1700 ± 50 ℃ of high temperature sinterings, by in the alundum (Al more than 90%, adding rare earth metal, and as yttria, unique formula productions such as rhodium oxide.Special ceramic block can be embedded in the metallic plate by following pouring procedure: fixedly be suspended at special ceramic block in the mould, melt metal liquid is cast in the mould, promptly obtains special ceramic block and sheet metal after the molten metal bath cooled and solidified and be fused into the extraordinary composite liner of holistic ceramic-steel iron.
Above-mentioned metal backing can adopt metal materials such as cast iron, cast steel or gray iron.
The special ceramic block that the present invention adopts can adopt main material preparation by following weight percentage to form: the Al about 90%
2O
3Reach rhodium sesquioxide, oxidation hundred million, dispersant, wherein dispersant is colourless or weak yellow liquid.Special ceramic block have good wearability can and heat endurance.
The invention has the beneficial effects as follows: the present invention is a skeleton with metal backing such as the metals such as cast iron, cast steel or gray iron sheet material with excellent impact resistance and anti-vibration resistance, with the good pottery of anti-wear performance as insert, and by special ceramic block being suspended in the metal backing fused solution, cooling forming again, thereby both performances are organically combined, make the present invention have good heat endurance, impact resistance, anti-vibration resistance and high temperature resistant.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a cross-sectional schematic of the present invention.
The specific embodiment
With reference to Fig. 1, Fig. 2, the extraordinary composite liner of ceramic-steel iron disclosed by the invention, comprise metal backing 1, be inlaid with several special ceramic blocks 2 by technologies such as casting or founding in the sheet metal 1, and special ceramic block 2 merges in aggregates with metal backing 1, the shape of metal backing can be made into square, polygon or other shape, also can be according to hopper, the interior shape of equipment such as hopper is determined, this metal backing can adopt cast iron, metal material such as cast steel or gray iron, cast iron preferably adopts spheroidal graphite cast-iron, wherein the fusing point of spheroidal graphite cast-iron reaches 1600 ℃, and the fusing point of cast steel reaches 1700 ℃, and the fusing point of gray iron also reaches 1200-1300 ℃.That special ceramic block can be made into is cylindrical, box-shaped or the like shape, and special ceramic block can mainly adopt the material preparation by following weight percentage to form: the Al about 90%
2O
3Reach rhodium sesquioxide, oxidation hundred million, dispersant, wherein dispersant is colourless or weak yellow liquid, and special ceramic block has good abrasion resistance, resistance to elevated temperatures and heat endurance.The high temperature of special ceramic block ability more than 1700 ℃ that adopts above-mentioned ceramic material to make.
The present invention is a skeleton with metal backing such as the metals such as cast iron, cast steel or gray iron sheet material with excellent impact resistance and anti-vibration resistance, with the good pottery of anti-wear performance as insert, thereby both performances are organically blended, therefore the present invention has good heat endurance, impact resistance and anti-vibration resistance and high temperature resistant, its Rockwell hardness HRA reaches more than 85, anti-wear performance is good, can directly the present invention be welded in the equipment such as hopper, hopper, thereby be convenient to installation of the present invention.
And; the special ceramic block that the present invention adopts is to be embedded in by the following method in the metallic plate: fixedly be suspended at special ceramic block in the mould; melt metal liquid is cast in the mould; get final product after making the molten metal bath cooled and solidified; the fusion of sheet metal and special ceramic block is in aggregates like this, and special ceramic block is not easy to come off from sheet metal, and sheet metal also plays a protective role to special ceramic block simultaneously; make special ceramic block be not easy fragmentation, can be adapted to various working conditions.
More than be that preferable enforcement of the present invention is specified, but the invention is not limited to described embodiment, those skilled in the art also can make various equivalent variations or replacement under the prerequisite of spirit of the present invention, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
