Steel Ladle Vermiculite Boards | High-Temp Insulation

Designed for high‑temperature insulation systems of metallurgical steel ladles, steel ladle vermiculite board adopts expanded vermiculite as the core raw material, and forms a stable porous structure through advanced sintering process, integrating high‑efficiency thermal insulation, high temperature resistance and corrosion resistance. In the actual production of steel plants, it is laid on the inner wall of steel ladles as a special insulation layer, which can effectively reduce the temperature loss of molten steel, ensure the stability of pouring temperature, and help to improve the mechanical properties and surface quality of steel. Its excellent thermal stability enables it to withstand long‑term baking and scouring of high‑temperature molten steel without softening, deformation or damage. The closed microporous structure reduces heat conduction and convection, greatly improving energy utilization efficiency and reducing production costs. It has strong anti‑stripping performance, adapts to the frequent temperature changes in the process of steel ladle turnover, and is not easy to burst and fall off. As an asbestos‑free and environmentally friendly material, it does not produce harmful substances in high‑temperature use, protecting the health of operators and complying with environmental protection standards. Lightweight and easy to cut and install, it shortens the maintenance time of steel ladles and improves production efficiency. It can be used together with other refractory materials to form a composite insulation system, enhancing the overall insulation effect. Customized products can be provided according to the size and structure of different steel ladles. Please contact us for price details and technical solutions.
