XinRuiJi offers high-quality customized fire grate bars for refuse incinerators. Our products are designed for efficient waste incineration. These fire grate bars are made from durable materials to withstand extreme conditions.
Materials
We use a range of materials, including cast iron, heat-resistant alloy steel, and high-chromium cast steel. Common materials include HT200, HT250, DIN 1.4710.
Dimensions
Our fire grate bars come in various sizes. For instance, Witdge Alloy provides a size of 450mm×200mm×45mm. The dimensions can be customized to meet specific needs.
Temperature Resistance
These fire grate bars are built to endure temperatures from 550°C to 1200°C. This makes them ideal for high-heat environments like refuse incineration.
Structure
The grate bars consist of fixed and movable parts. The movable bars are driven by chains, pushing waste into the incinerator for combustion.
Surface Treatment
Our products undergo sandblasting to improve surface quality and durability. This enhances performance in harsh conditions.
Manufacturing Process
We use advanced casting techniques such as vacuum casting, resin sand core casting, and precision lost-wax casting. These methods ensure high-quality, durable products.
Performance
Our fire grate bars are designed for exceptional wear resistance. They also have corrosion resistance, protecting them from the harsh, corrosive environment of a waste incinerator.
Certification
Some of our fire grate bars are ISO 9001:2008 certified. This ensures our products meet international quality standards.
Application
These fire grate bars are primarily used in refuse incinerators. They help push waste into the furnace for high-temperature combustion, ensuring efficient waste management.

High-Temperature Resistance
Made from heat-resistant cast iron, alloy steel, and high-chromium cast steel, these bars can withstand temperatures from 550°C to 1200°C without cracking or warping.
Special structural designs, such as heat-insulating layers, further enhance heat resistance and extend their lifespan.
Wear Resistance
The high-chromium cast steel provides excellent hardness and wear resistance, preventing damage from abrasive particles like ash and debris.
Some models undergo sandblasting to improve surface texture, ensuring better friction and smoother waste movement across the bars.
Corrosion Resistance
The materials resist corrosion caused by acidic gases and chlorides generated during incineration, preserving the integrity of the bars.
Some fire grate bars are coated with high-temperature, anti-corrosion coatings, offering extra protection and enhancing their service life.
Structural Stability
The design ensures sufficient strength and rigidity to withstand the weight of waste and forces during combustion.
Reliable connections between bars, such as high-strength bolts or welding, ensure long-term stability and prevent loosening or detachment.
High Adaptability
These bars are compatible with various waste types, including municipal, industrial, and medical waste, without compromising performance.
They perform reliably under continuous or intermittent use, adapting quickly to load changes and furnace start-up or shut-down cycles.
Ease of Maintenance
The modular design allows for quick replacement of individual bars, minimizing downtime and reducing maintenance costs.
The bars are designed for easy cleaning, preventing ash accumulation and helping maintain combustion efficiency.
High Combustion Efficiency
The arrangement and shape of the fire grate bars enhance air circulation and optimize waste distribution, promoting efficient combustion.
Their durability reduces the occurrence of unburned waste, contributing to lower residue and improving overall waste incineration efficiency.
The production process of our fire grate bars involves several key steps, ensuring high quality and durability:
Furnace Selection: Heat-resistant steel is melted in electric arc or induction furnaces; high-quality alloys use vacuum refining.
Charging Sequence: Charge hard-to-melt alloys first, followed by scrap steel using a specific layering method.
Melting and Deoxidation: Maximum furnace power is used to melt metals, followed by deoxidation with ferromanganese, ferrosilicon, and aluminum.
Pouring: Once the temperature reaches 1480°C, the molten iron is poured after resting in the furnace for proper settling.
Casting Process Selection: High-alloy heat-resistant steels are cast for their superior strength, especially in fire grate bars.
Mold Making: Molds are created based on the product’s shape and size using sand casting, metal mold casting, or lost-wax casting.
Pouring Control: The pouring temperature is carefully controlled at 10-30°C above the liquidus line, and chromium carbide powder is added for enhanced crystallization.
Pearlitic Heat-Resistant Steel: Generally normalized or tempered to improve performance.
Martensitic Heat-Resistant Steel: Tempered to stabilize structure and enhance mechanical and high-temperature strength.
Ferritic Steel: Annealed to relieve internal stresses and avoid brittleness in the temperature range of 650-830°C.
Austenitic Oxidation-Resistant Steel: Treated with high-temperature solution heat treatment for improved cold formability.
Austenitic Heat-Resistant Steel: Solution treated and aged at 60-100°C above the working temperature for structural stability.
Casting Cleaning: Burrs and flashing are removed, followed by polishing to improve surface finish.
Machining: Precision machining such as turning or milling ensures the required dimensions and shapes.
Surface Treatment: Surface treatments like sandblasting, painting, or coating improve corrosion and wear resistance.
