Aluminium

Industrial thermal insulation materials are crucial in aluminum casting processing to maintain melt temperature, reduce energy costs, and improve the casting quality, typical materials include ceramic fiber boards, calcium silicate boards, and insulating castable, which have a low thermal conductivity, high-temperature resistance, and non-wetting aluminum properties, preventing reactions with molten aluminum. They are used in various applications like holding furnace bath linings, ladles lining, and transfer troughs, launders, spouts, floats, hot top ring headers, and holding furnaces for die-casting. ensuring efficient heat management throughout the casting process.

High Density Calcium Silicate Board is an ideal thermal insulation materials for aluminum casting. In the aluminum casting processing, high density calcium silicate board is one of the key materials for getting high quality aluminum, its excellent strength & quite low thermal conductivity and good performance at high-temperature conditions make it the most suitable material to be used as lining for smelting, casting, and molten metal handling. These boards address limitations of traditional materials like ceramic fiber or refractory bricks by combining durability, thermal efficiency, and chemical resistance.

NR-80 boards and NR-85 boards are two most widely used products for aluminum casting also including the components such as transition plates, bushes and tubes made from them, these materials are a xonotlite-based calcium silicate materials with excellent heat resistance, excellent in machinability.  NR boards are reinforced with caron fiber or glass fiber, which endure they have a quite great performance on shock resistance and enhance the life span of casting equipment.
