I.What is silicon carbide corundum Refractory plastic?
Silicon carbide corundum refractory plastic is a high-performance monolithic refractory material refined from high-purity silicon carbide and fused alumina (Al2O3≥88%) as core aggregates, combined with composite binders and functional additives. This material combines the ultra-high hardness of silicon carbide with the excellent high-temperature stability of corundum, forming three core advantages:
1.Wear-resistant and erosion-resistant
Wear amount ≤4cm³/1100℃×3h, which is more than 40% better than ordinary refractory materials. It can withstand the high-frequency impact and cutting wear of materials in circulating fluidized bed boilers and metallurgical kilns.
2.Good thermal shock stability
Applicable temperature 1200℃~1700℃, short-term tolerance limit up to 1800℃, excellent thermal shock stability, no cracks after ≥50 water cooling cycles, can adapt to the temperature fluctuation conditions of frequent start-up and shutdown of kilns;
3.Super strong adhesion and formability
No steel formwork is required. It can be applied to any irregular part by coating and tamping. After construction, the adhesion strength with the substrate is ≥3.5MPa, which can effectively solve the protection problem of complex furnace structure.
II. Application Scenarios of Silicon Carbide Corundum Refractory Plastics
Our products have been widely used in core industrial sectors such as metallurgy, building materials, power, and petrochemicals worldwide.
Power industry: Wear-prone areas such as the dense phase zone of the furnace, the inlet of the cyclone separator, and the discharge port of the return feeder in CFB circulating fluidized bed boilers;
Metallurgical industry: Iron tapping trough of steel blast furnace, lining of non-ferrous metal smelting furnace, working layer of continuous casting tundish;
Building materials industry: Transition zone of cement rotary kiln, firing zone of ceramic kiln, regenerator of glass melting furnace;
Petrochemical industry: Repair of catalytic cracking units, oil refinery furnace linings and wear-resistant pipeline linings.
III. Construction and Usage Advantages
We offer a convenient end-to-end solution tailored to the specific characteristics of project construction:
High construction efficiency: No special large equipment is required; it can be formed by manual tamping, which increases construction efficiency by 50% compared to castable refractory and can significantly shorten the construction period.
No oven drying required: No special maintenance is needed after construction; the furnace can be ignited and operated directly, saving oven drying costs and time, making it particularly suitable for emergency repair projects.
Long service life: The design life is 3 to 5 years under normal working conditions, and it can be extended to 6 to 8 years through scientific maintenance.
