Classification, Performance and Applications of Mainstream Grate Plate Materials Core requirements for grate plates: high-temperature resistance, thermal shock resistance, wear resistance, oxidation resistance and resistance to ash and slag corrosion. Listed below in order of most common use in industrial boilers: I. Standard cast iron types (the preferred choice for small-scale, low-temperature, atmospheric-pressure coal-fired boilers; offering the best value for money) 1. Grey cast iron (HT150/HT200) Characteristics: Lowest cost, simple casting, good thermal conductivit..

A comprehensive, practical approach to selecting grate bar materials Core selection logic: combustion temperature > fuel type (sulphur, ash, corrosion) > stress conditions of the grate structure > budget; simply compare these factors step by step to make your selection. I. Step 1: Determine the long-term operating temperature of the furnace chamber (the most critical indicator) The primary cause of grate failure: high-temperature oxidation and burnout, and cracking due to thermal expansion and contraction. Selection criteria based on temperature: Operating temperature <..

I. Basic Material Parameters Grade: RTSi5, heat-resistant cast iron conforming to Chinese national standards, with a silicon content of 4.5%–5.5% and a predominantly ferritic matrix; Design long-term safe operating temperature: 750°C–850°C; capable of withstanding short-term peak temperatures of up to 880°C. II. Comprehensive Performance (under optimal conditions) within the Suitable Temperature Range (750–850 °C, typical boiler operating conditions) 1. High-Temperature Oxidation Resistance (Key Advantage) A dense, intact protective layer of SiO₂ (silicon dioxide) spontaneously forms ..
