The impact-resistant and wear-resistant steel plate is different from the general wear-resistant composite steel plate. Nanomaterials are added to it. Its metallographic structure is fine and its structure is stable. According to customer feedback, the service life of the imported wear-resistant composite steel plate is only about 42 days, and the cost reaches 10 10,000 yuan per ton, and the service life of our impact-resistant and wear-resistant steel plate has been 4 months, and it is still in use. The president of a famous international wear-resistant steel plate sighed and visited the site. It is expected that this will be a steel plate material. A revolution, Beijing Naimer company also began a new course of development.
The impact-resistant steel plate is a wear-resistant layer with high toughness and strong bonding force formed by bonding up to 40%-60% of the carbide molten alloy to a suitable steel substrate by means of a laser. The material of the surfacing layer of the laminate is uniform, the appearance is regular, the carbides in the metallographic structure of the wear-resistant layer are distributed in a distinct manner, and are perpendicular to the surface, and the surface hardness can reach HRC63 or more. The steel plate is suitable for the environment with extremely severe impact wear. .
2. Application scope of impact resistant steel plate
Metallurgical industry: chutes, fans, weighing hoppers, powder separator blades, slide plates, slag removal pipes, blast furnace top hoppers.
Coal industry: cone wear-resistant lining plate of wheel bucket excavator, middle trough plate of scraper type coal conveyor, feeding trough, hopper, mine hoisting skip, coal washing plant pipeline, chute.
Cement industry: scraper, chute, air guide cone, guide fan blade, dust removal pipe. Slag chute.
Electric power industry: fan blades, burner pipelines, stacker and reclaimer hoppers, silo linings, coal mill linings, pulverized coal conveying pipes, pulverized coal distributor grids, coal unloading equipment linings.
3. Production process of impact-resistant and wear-resistant steel plate
The production process of impact-resistant and wear-resistant steel plate adopts the most advanced laser plasma process. The impact-resistant and wear-resistant steel plate is a wear-resistant layer with a volume fraction of more than 50% Cr7C3 carbide formed on the ordinary steel plate (Q235 (A3) or heat-resistant steel plate (15CrMo, 12Cr!MoV, etc.) and stainless steel plate. It has properties such as high wear resistance, impact resistance, deformability and weldability. It can be directly curled, deformed, cut and punched like a steel plate, and processed into engineering parts to meet the needs of wear and mining. It is used in many wear-resistant industries. Compared with materials, impact-resistant steel plate has its irreplaceable characteristics.
4. Advantages of impact-resistant and wear-resistant steel plates
1. Good impact resistance:
The base plate of the impact-resistant steel plate is made of ductile materials such as low-carbon steel or low-alloy steel, stainless steel, etc., which reflects the superiority of bimetal. It can withstand impact and wear such as high drop hoppers in material conveying systems.
2. Excellent wear resistance
The chemical composition of the alloy wear-resistant layer has a carbon content of 2.5%-3.5%, and a chromium content of up to 40%-50%. The volume fraction of Cr7C3 carbide in its metallographic structure is more than 50%. The hardness value of chromium is HV1700-2000. Since the carbides are distributed perpendicular to the wear direction, the wear resistance is more than three times higher than that of the cast gold items with the same hardness. The wear resistance comparison with several typical materials is as follows:
(1) and low-alloy carbon steel; 20 to 25:
(2) Paste steel with ceramics; 12~18
(3) Cast iron with Menggang; 16
(4) With tool steel; 13.5
(5) Ordinary wear-resistant steel; 6~8
3. Improve economic efficiency: reduce downtime and improve equipment operation rate
Improve equipment work rate, reduce downtime and maintenance losses, increase production capacity, and increase efficiency
4. Good heat resistance
The alloy wear-resistant layer has been recommended to be used under the working condition of ≤600℃. If vanadium, molybdenum and other alloys are added to the alloy wear-resistant layer, it can withstand high temperature wear of ≤800℃-900℃.
Recommended operating temperatures are as follows:
Ordinary carbon steel substrates are recommended to be used under working conditions of not higher than 380 °C;
Low alloy heat-resistant steel plates (15CrMo, 12Cr1MOV, etc.) substrates are recommended to be used under the working condition of not higher than 450 °C;
The heat-resistant stainless steel substrate is recommended to be used at a temperature not higher than 560°C.
5. Good corrosion resistance, strong impact resistance and certain shock resistance.
The alloy layer of the impact-resistant steel plate contains a high percentage of metallic chromium, so it has certain rust and corrosion resistance. It can prevent coal from sticking when used in coal drop drums and funnels, and has strong bottom impact resistance and certain shock resistance in the mining crushing industry.
6. Complete varieties and specifications
Wear-resistant steel plates are complete in specifications and varieties, and have become serialized products. The thickness of the wear-resistant alloy layer is 3-35mm, and the minimum thickness of the composite steel plate is 4mm, and the thickness is not limited. At present, the standard wear-resistant steel plate can provide 1200 or 1450×3000mm,=4.35㎡1500×6000㎜=9㎡, and can also be customized according to the user's needs and the size of the drawings. The wear-resistant steel plate is divided into three types: ordinary type, impact-resistant type and high-temperature type. Ordering high-temperature wear-resistant and impact-resistant composite steel plate should be explained.
7. Aspects of processing performance
Wear-resistant steel plate can be cut, bent or coiled, welded and punched, and it can be processed into various parts that ordinary steel plates can process. The cut wear-resistant steel plate can be tailored and welded into various engineering structural parts or components.
8. Functions and features,
Weldable, impact resistance, good wear resistance,
As mentioned above, the impact-resistant and wear-resistant steel plate has the dual properties of high hardness material and toughness material, which is compared with other engineering wear-resistant materials such as various alloy steel plates, cast wear-resistant plates, cast stone, rubber, ceramics, polyurethane, etc. , has irreplaceable comprehensive excellent performance, you are welcome to choose, and I hope our company's impact-resistant and wear-resistant steel plate can solve the problem of impact and wear in the production process for you.
