Wear-resistant liner characteristics
1.High wear resistance The thickness of the wear-resistant layer of the composite wear-resistant liner is 3-12 millimeters,. The hardness is HRC58-62. The abrasion resistance is more than 15-20 times that of ordinary steel plate, 5-10 times that of low alloy steel plate, and 2-5 times that of high chrome cast iron. Wear resistance is much higher than spray welding and thermal spraying. 2. Good impact performance
1.High wear resistance
The thickness of the wear-resistant layer of the composite wear-resistant liner is 3-12 millimeters,. The hardness is HRC58-62. The abrasion resistance is more than 15-20 times that of ordinary steel plate, 5-10 times that of low alloy steel plate, and 2-5 times that of high chrome cast iron. Wear resistance is much higher than spray welding and thermal spraying.
2. Good impact performance
Wear-resistant liner is a double-layer metal structure. The wear-resistant layer is metallurgically bonded to the base material with high bonding strength. Energy is absorbed during the impact process, and the wear-resistant layer will not fall off. Applicable to vibration, impact conditions, than casting wear-resistant materials, ceramic materials.
3. Good temperature resistance
Composite wear-resistant liner carbide has a strong high temperature stability. Wear-resistant liner can be used at 500 ℃, other special requirements can be customized, can be used at 1200 ℃; ceramics, polyurethane, polymer materials and other wear-resistant materials can not meet the requirements of such a high temperature.
4. Good connection performance
The base material of composite wear-resistant liner is ordinary Q235 steel plate. It ensures the toughness and plasticity of the composite wear-resistant liner and provides the strength to resist the external force. It can be connected with other structures by welding, plug welding, bolting and so on. Firm connection, not easy to fall off, more connection methods than other materials;
5. Good selection performance
Wear-resistant liner plate adopts different thickness of base material and different layers of alloy wear-resistant layer. Obtain different thicknesses of steel plates for different purposes, and the maximum thickness can be more than 30 millimeters;
6. Good processing performance
Wear-resistant liner plate can be processed into different specifications and sizes according to the needs,. Can be processed, cold molding, welding, bending and so on. , easy to use; can be welded on-site molding, maintenance and replacement work is time-saving and convenient. Greatly reduce the work intensity.
7. Good gender-price ratio
The price of wear-resistant liner is higher than ordinary materials, but considering the service life of the product, maintenance costs, spare parts costs and downtime losses, its price-performance ratio is much higher than that of ordinary steel plates and other materials.
Double-arch space laying wear-resistant liner structure is a new type of structure proposed by applying the design concepts of large-span space structure and bionics. The structure has the advantages of high stiffness, steel saving, clear force transmission path and simple joint design.
Calculations show that, compared with the ordinary gate structure. Steel consumption is reduced by about 30%. The company studied the double arch structure on the basis of the completed double arch steel pipe gate. Firstly, the origin of this structure is discussed and the concept of double continuous arch space structure is introduced. Compared with the traditional solid web beam and common truss structure. The advantages of the double arch structure are demonstrated, and the application of the double arch space steel tube structure in the tidal floodgate is introduced.
Then, the parameters and shapes of the continuous arch structure were optimized, including the number of arrangements of the continuous arch structure, the linear shape of the continuous arch and the thick span ratio. The effects of load, end-span ratio, span and chord were considered. Meanwhile, based on the optimization results, a searchable design table was established to provide a basis for designers to carry out preliminary design. In addition, SURFACE wear-resistant liner double arch structure is introduced in the design of flat plate gates and herringbone gates, and the parameters in the application are analyzed. Steel pipe structure has been widely used in space structure with its unique superior performance.
