Products Description
The structural design of the Grate Bar For Power Plant is optimized according to the actual working conditions of power plant boilers, focusing on practicality and durability. We adopt a scientific cross-sectional structure and reasonable force-bearing design, which makes the Grate Bar For Power Plant have uniform force during operation, strong load-bearing capacity and good thermal conductivity, ensuring full combustion of fuel (coal, biomass, waste, etc.) and improving the thermal efficiency of the boiler. At the same time, the Grate Bar For Power Plant has precise dimensional control, which can be perfectly matched with the boiler grate frame and transmission mechanism, ensuring smooth operation without jamming and reducing the risk of equipment failure.
Compared with ordinary grate bars, our Grate Bar For Power Plant has obvious competitive advantages in performance and service life. Its wear resistance is 5-8 times that of ordinary carbon steel grate bars, and it has strong corrosion resistance to acid-base flue gas and ash in power plant boilers, which greatly extends the service life of the product. The long service life of the Grate Bar For Power Plant reduces the frequency of replacement and maintenance, shortens the downtime of the power generation system, and effectively reduces the comprehensive operation cost of power plants.
Core requirements for power plant operation matching
The working environment of Grate Bar for Power Plant in power plants is extremely harsh. During operation, they are continuously baked by high-temperature sintering materials and subjected to severe wear and corrosion. To adapt to such working conditions, this product must meet strict performance standards: first, excellent wear resistance and heat resistance to withstand long-term high-temperature erosion and material friction; second, high casting quality, with dense internal structure and high flatness to avoid structural damage caused by temperature changes and load pressure; third, balanced cost and service life, as a single set of sintering trolley requires a large number of grate bars, which needs to achieve cost control while ensuring long service life.
Product material
We provide grate bars made of two major categories of high-performance materials, covering the diverse needs of power plant sintering operations, and supporting customization according to customer drawings and requirements:
High Manganese Cast Steel Series
Including Mn13, Mn18, Mn22, Mn13Cr2, Mn18Cr2, Mn22Cr2, Mn13CrMo, Mn13CrMoNi. This series of materials has excellent impact toughness and work hardening performance, which can effectively resist the impact wear of bulk sintering materials, and is suitable for working conditions with high material fluidity.
High Chrome Steel Series
Including Cr13, Cr15, Cr18, Cr20, Cr25, Cr27, Cr15Mo1, Cr18Mo1, Cr25Mo0.5Ni0.5. Among them, the Cr25 high-chromium grate bar is specially optimized by inoculation with multiple active elements, which significantly improves its toughness, with an ak value reaching 8~12J/cm², and its oxidation resistance is increased by 50~80%, showing outstanding performance in high-temperature and corrosive environments.
