- Product Introduction
As a long-standing partner deeply rooted in the foundry industry, we understand that the reliability and lifespan of your high-temperature furnace grates are critical to your productivity efficiency and operating expenses.
Today, I take great pride in introducing our factory's core advantage: heat-resistant grate plates (grate segments) made from high-chromium cast iron - fully customizable to your exact requirements!
About our company
Tengzhou Tiangong Machinery Co., Ltd. is a professional precision casting production enterprise with product development ability, quality assurance ability and batch product production ability.
Founded in June 2004, it is located in Nilou Industrial Park, Guanqiao Town, Tengzhou City, Shandong Province. It now has 82 employees, covering an area of 13,000 square meters and a workshop area of 10,000 square meters. Equipped with Germany imported spectrum analyzer, the United States standard mechanical performance testing machine, domestic famous brand impact testing machine, hardness meter and other a full set of physical and chemical equipment.
Why Choose Our High-Chromium Cast Iron Grate Plates for Your Demanding High-Temperature Applications?
Superior High-Temperature Performance
We utilize high-chromium cast iron (e.g., Cr30 grade) with chromium content up to ~30%. At elevated temperatures, this alloy forms a dense, stable chromium oxide (Cr₂O₃) protective layer, delivering:
Exceptional resistance to high-temperature oxidation (scaling) and gaseous corrosion
Reliable operation in environments exceeding 1000°C (1832°F)
Effective prevention of rapid degradation observed in conventional materials.
Superior Thermal Fatigue & Creep Resistance
Our high-chromium cast iron delivers exceptional high-temperature strength and hardness. Under rigorous thermal cycling (repeated heating-cooling), it significantly outperforms standard cast iron or heat-resistant steel in:
Resistance to deformation and cracking (thermal fatigue).
Outstanding high-temperature creep resistance.
Ensuring furnace grates maintain structural stability under prolonged high-temperature/heavy-load conditions without collapse or warping.
Exceptional Wear Resistance & Growth Stability
Our high-chromium cast iron features a high-hardness matrix reinforced with hard carbides, delivering outstanding wear resistance against fuel ash slag and furnace charge abrasion. With superior high-temperature microstructural stability, it exhibits minimal thermal growth (volumetric expansion), ensuring:
Long-term dimensional integrity of grate clearances
Consistent airflow distribution within the furnace
Guaranteed Reliability
We leverage advanced vacuum sealed molding (V-process) or lost foam casting technologies, combined with:
Precisely controlled melting via medium-frequency furnace refining
Scientifically optimized heat treatment (quenching & tempering)
This ensures each grate plate achieves:
● Defect-free internal integrity with uniform microstructure.
● Maximum performance realization of high-chromium cast iron.
Every product undergoes rigorous inspection before shipment under our certified quality control system.
We are not commodity suppliers of standard parts; we are casting specialists solving the challenge of short high-temperature grate lifespans!
Using high-performance high-chromium cast iron materials and deep customization capabilities, we build durable, long-lasting, stable, and high-efficiency grate solutions for you.
