Product Details
6+4 composite wear-resistant steel plate 6+5 6+6 8+6 10+6 surfacing wear-resistant manufacturers


Wear-resistant composite steel pipe is made of ordinary steel pipe (Q235 20#, 35#, 45#, 20G, 16Mn (Q345A, B, C, D), 27SiMn, 15-42CrM0+ wear-resistant layer 4mm 5mm 6mm 8mm 10mm) and high wear resistance The alloy composition, that is, the high wear-resistant alloy is metallurgically combined with the substrate through a special surfacing welding process, forming a layer of 3-6MM wear-resistant alloy layer on the inner wall of the steel pipe, the hardness is 58-67HRC.

Wear-resistant steel plate; copper-steel composite steel plate; wear-resistant composite steel pipe; bi-metal wear-resistant composite steel plate;; wear-resistant electrode; double-metal composite pipe; Tian place round transition pipe wear-resistant three-way wear-resistant round steel wear-resistant elbow; Grinding liner; wear-resistant sieve plate; wear-resistant chute; wear-resistant hopper; fly ash conveying pipe; surfacing welding wear-reducing pipe; vibrating sieve plate; plasma surfacing machine

Wear-resistant layer alloy composition: C: 5.0%, Cr: 27-30%, martensite matrix + a large number of Cr7C3 type carbides of more than 60%
Composite wear-resistant steel plate hardness: alloy layer macro hardness HRC57-65, carbide hardness HV1400-1800
Abrasion resistance: 20-25 times of low carbon steel, 8-12 times of stainless steel and high manganese steel, 1.5 times or more of general high carbon high chromium wear resistant steel plate
High temperature resistance: normal type <600 ° C; high temperature type <1000 ° C
Impact resistance: The wear-resistant alloy layer is completely metallurgically bonded to the substrate, resisting strong impact, and does not have to worry about falling off.
Advantages of wear-resistant composite steel pipe:
1. High anti-wear performance: Fully automatic CNC stacking equipment, independent of manual welding technology, produces fully qualified high quality products, special automatic welding technology to control the chromium content of the wear layer to more than 28%, hardness Between 58-62, we ensure that our wear layer has a consistently good, balanced wear resistance. Through the wear test of metallurgy, cement and other industries, it is confirmed that the wear resistance of the wear-resistant composite steel plate wear layer is equivalent to 30 times of the 16Mn plate of the same thickness.
 
2. High impact resistance: Due to the use of mild steel substrate, the wear-resistant composite steel plate has high impact resistance, which fully reflects the advantages of the composite material being both wear-resistant and impact-resistant. This is beyond the reach of as-cast wear resistant materials.

Application of composite wear-resistant steel pipe:
 
Composite wear-resistant steel pipe can be used for surface strengthening of various wear-resistant equipment parts in steel metallurgy, building materials machinery, electric machinery, mining machinery, cement industry, wind turbine industry, and other industries.
 
(1) Cement industry: the selection of powder blades, mixer blades, skid platforms, internal grinding liners, wind guide cones, conveying pipes, vibrating screens, silos, chutes, and repair of cement vertical mills.
 
(2) Fan industry: fan impeller, cyclone separator, fan blade, rear disc liner, fan port, easy to wear parts, etc.
 
(3) Steel metallurgy: cloth chute, silo lining, sloping ramp, net curtain, blast furnace bell-shaped hood, skip, blast furnace strengthened steel plate, sintering feed cylinder, pipeline, distribution plate, slag slag , exhaust fan, blast furnace tank liner, dry quenching coke tank liner, push-cart car lining skateboard bottom plate, sliding car lining skateboard bottom plate, sintering machine single roll crusher, scraper, water beam and siding repair production, etc. .
 
(4) Coal industry: the cone wear-resistant lining of the bucket excavator, the middle tank of the scraper type coal conveyor, the feed trough, the hopper, the well mine lifting bucket, the pipe of the coal washing plant, and the chute.
 
(5) Electric machinery: fan impeller, coal ash pipe, silo, feed trough, coal conveying parts, hopper lining, medium-speed grinding mill repair, burner nozzle, etc.
 
(6) Other industries: solar glass, mining machinery, construction machinery, coal mining machinery, wear-resistant fan manufacturing, brick making, sand mining, silo lining in the coal industry, scraper conveyor bottom plate, sieve plate, etc.
 
(7) Providing the surfacing board directly to the user, and the user can cut off the material by himself, and complete the on-site construction project such as silo, chute, big bucket, stacking and unloading equipment.
 
(8) According to the size of the wear area of ​​the user parts, the collar unit is provided for on-site tailor welding maintenance to reduce the on-site welding workload, such as the bucket of the working machine and the dredger of the dredger.

7390 6+4 composite wear-resistant steel plate, the price has changed from rising to falling
In the market, prices have gone from rising to falling. The price of 6+4 composite wear-resistant steel plate increased slightly. 6+4 composite wear-resistant steel plate market deviation, merchants in order to ship, compete to cut prices. In the area where the price of 6+4 composite wear-resistant steel plate increased slightly, the transaction also shrank day by day.

    In the 6+4 composite wear-resistant steel plate, the price slowed down. The price of 6+4 composite wear-resistant steel plate has widened, and the price of Shanghai, Hangzhou and Guangzhou has dropped by 20 yuan to 110 yuan per week. The price of the northern market has been low, which has led to the gradual southwardness of resources. The pressure on the 6+4 composite wear-resistant steel plate market is also increasing, and the bearish sentiment in the market is increasing. The price of 6+4 composite wear-resistant steel plate continued to weaken and fell. When the market of 6+4 composite wear-resistant steel plate was light, it was difficult to effectively suppress the continuous decline of prices.

   The 6+4 composite wear-resistant steel plate market is becoming more and more “dismal”. In the 6+4 composite wear-resistant steel plate market, the price of 6+4 composite wear-resistant steel plate fell sharply. As of the 6th, the 6+4 composite wear-resistant steel plate index closed at US$47.8 per ton, down by US$2.1 per week. In the case of oversupply, international mainstream mining companies insisted on continuing to expand production and reduce costs. Mine shipments remained stable and port inventory remained at a high level. The 6+4 composite wear-resistant steel plate plant continues to lose money, the expectations of steel mills to reduce production are increasing, and the demand for ore is subject to greater pressure. Some international investment banks predict that global iron ore prices will fall to $40 per ton in the next two years. The price of 6+4 composite wear-resistant steel plate fell below the marginal output cost line, which triggered the discontinuation of production by mining enterprises.

    The demand for 6+4 composite wear-resistant steel plate will continue to weaken. The contradiction between supply and demand of 6+4 composite wear-resistant steel plate will be intensified, and the price of 6+4 composite wear-resistant steel plate will also face downward pressure.
