Qingyun Hongsheng Machinery Parts Co., Ltd. is one of the most reliable manufacturers and suppliers of wear-resistant lining casting with material zg35cr24ni7sin in China. We warmly welcome you to wholesale high quality wear-resistant lining casting with material zg35cr24ni7sin at low price from our factory. If you have any enquiry about quotation, please feel free to email us.
When high temperature, material abrasion and flue gas corrosion coexist in your furnace, ordinary steel liners will deform, crack and wear out rapidly, causing frequent shutdowns and extra maintenance costs. Our ZG35Cr24Ni7SiN casting lining plate is professionally developed for harsh high-temperature working conditions of coke ovens, heating furnaces, sintering kilns and incinerators, integrating high-temperature resistance, anti-abrasion and anti-corrosion performance to extend your equipment service life drastically.
Products Description
Core Material Advantage of ZG35Cr24Ni7SiN Alloy
ZG35Cr24Ni7SiN is a premium austenitic heat-resistant cast steel with balanced chemical composition of carbon, chromium, nickel, silicon and nitrogen, complying with national casting standard GB/T 8492-2014.
◆24% High Chromium Content
Forms dense anti-oxidation protective film on the surface under 1100℃ high temperature, resisting sulfur flue gas corrosion, high-temperature oxidation and slag adhesion.
◆7% Nickel & Nitrogen Reinforcement
Stable austenite microstructure, excellent thermal shock resistance. No cracking or deformation under repeated cold-heat cycling of furnace start-stop. Nitrogen element strengthens high-temperature hardness while cutting extra material cost.
◆Optimized Silicon & Manganese Ratio
Improves casting fluidity and grain refinement, eliminates internal casting defects like pores and sand holes, guarantees consistent mechanical performance of each lining plate.
Two Main Types to Match Your Working Conditions
1. ZG35Cr24Ni7SiN Wear Resistant Lining Plate
Designed for positions with continuous high-temperature material scouring: coke oven feeding chute, furnace inlet & outlet guide plates, sinter machine high-temperature blanking sections.
Outstanding high-temperature anti-abrasion performance, resistant to friction impact of hot coke, clinker and high-temperature ore;
Hard oxide layer will regenerate automatically after slight surface abrasion, stable long-term wear resistance.
2. ZG35Cr24Ni7SiN Heat Resistant Lining Plate
Mainly used for furnace wall lining, furnace door guard plate, furnace base side baffle and static high-temperature protection areas.
Continuous service temperature up to 1050℃, short-term peak temperature reaches 1200℃ without creep deformation;
Ultra-low thermal expansion rate, effectively protect furnace shell from high-temperature damage, reduce heat loss.
Compare with Ordinary Wear-Resistant Materials
VS ZGMn13Cr2 Manganese Steel: ZGMn13Cr2 only works under room temperature; its wear resistance collapses above 400℃. Our ZG35Cr24Ni7SiN maintains stable performance under 1100℃ high temperature, the only choice for high-temperature abrasion scenarios.
VS Carbon Steel & Low Alloy Steel: Carbon steel liners oxidize severely above 600℃, crack after several furnace cycles. Our alloy liner reduces replacement frequency by 3-5 times, cutting your spare part and shutdown cost greatly.
Our Production & Customization Service
Precision Sand Casting Process: Strict mold control to avoid internal defects, full annealing stress relief after casting to prevent deformation during high-temperature operation.
Full Drawing Customization: We produce lining plates strictly according to your drawing numbers (such as E220033 series, 2K202222 series). We can machine bolt holes, lap grooves and reinforcing ribs as your technical requirements.
Complete Quality Inspection: Each batch has chemical composition test, high-temperature tensile test and hardness test; test reports can be provided for import customs clearance.
