China Sinter Machine Grate Bars Suppliers - High-Quality Factory Cast Parts with 2Cr13 and ASTM HI Materials
We use coated sand shell superposing casting method for casting. This production process can ensure the stability of the internal structure of the grate bar. This technique not only makes the grate bars have beautiful surface but also increase the production efficiency.
Our related products mainly export to Japan, Germany, Russia and etc. With strict technique requirements of our long term customers, we never stop researching and developing to increase the products quality and the quality stability and make great success!

Grate bar is the main part of sintering machine. The grate bars are intended for holding and transporting the ore mill by forming a trough space with the railing plates on the pallets.
Variety grate bars with good heat resistant abrasion resistant and corrosion resistant capability. For Cr25 high Cr grate bars are inoculated with multiple active elements so its toughness increased largely, ak value achieved 8~12J/cm2, inoxidizability also increased 50~80%, shell mould casting, good surface roughness, accurate dimension.
DIN 1.4777 is a high-temperature resistant austenitic stainless steel material. It exhibits good mechanical properties, including high tensile strength, excellent creep resistance, and good fatigue strength. It also demonstrates a high resistance to oxidation and corrosion at elevated temperatures, making it suitable for use in applications such as furnace components, heat treatment equipment, and exhaust systems in automotive and industrial settings.
Frequently Asked Questions
What casting method is used for your grate bars?
We use the coated sand shell superposing casting method. This production process ensures the stability of the internal structure of the grate bars, improves surface appearance, and increases production efficiency.
What are the main functions and features of your grate bars?
Grate bars are the main parts of sintering machines, designed to hold and transport ore mill by forming a trough space with railing plates on pallets. Our grate bars offer excellent heat, abrasion, and corrosion resistance.
What makes your Cr25 high Cr grate bars unique?
Our Cr25 high Cr grate bars are inoculated with multiple active elements, which significantly increases toughness (ak value achieved 8~12J/cm²), and improves inoxidizability by 50~80%. They feature shell mould casting, excellent surface roughness, and accurate dimensions.
What are the properties and applications of DIN 1.4777 material?
DIN 1.4777 is a high-temperature resistant austenitic stainless steel with excellent tensile strength, creep resistance, fatigue strength, and oxidation resistance. It is commonly used in furnace components, heat treatment equipment, and industrial or automotive exhaust systems.
How do you guarantee product quality and traceability?
We implement a strict QC system along with complete inspection tools. We provide fully traceable material certificates and testing reports, and we report production progress to our customers in a timely manner.
