High-purity Alumina Hollow Ball Solves Heat Loss and High-temperature Aging Problems of Steel Industrial Furnace Linings

Project Overview

Our client is a professional iron and steel smelting manufacturer, focusing on carbon steel and alloy steel production. Its steel ladles, heating furnaces and tundishes work under long-term high-temperature circulating conditions, requiring lightweight, high-temperature resistant and stable thermal insulation refractory raw materials to ensure furnace body stability and reduce production energy consumption.

Our client is a professional metallurgical and steel enterprise, mainly engaged in steel smelting and processing. A large number of high-temperature industrial furnaces and steel ladles are used in the production process, which require lightweight and high-efficiency thermal insulation refractory raw materials to reduce heat loss.

Customer Pain Points

Traditional steel furnace insulation materials have high bulk density, poor thermal insulation effect and unstable high-temperature performance. Long-term impact of high-temperature flue gas and molten steel radiation leads to serious heat loss, fast lining aging and peeling, frequent furnace maintenance, and high energy consumption and production cost in steel smelting.

Traditional thermal insulation materials have high bulk density, large heat conduction and poor high-temperature stability. The equipment has serious heat loss, high surface temperature and large molten steel temperature drop, resulting in high energy consumption and unstable smelting quality.

Our Solution

We provide high-purity alumina hollow ball with uniform particle size and ultra-low thermal conductivity. As a key lightweight thermal insulation raw material for steel furnace linings and ladle back insulation layers, it has excellent high-temperature stability and pressure resistance. It can effectively fill the gaps of refractory layers, form a closed thermal insulation structure, and isolate high-temperature heat conduction.
