Product Description

Aluminum silicate plugging sleeve is sometimes also called asbestos plug and insulation cap for the outlet of the aluminum-copper-zinc smelting furnace. It is mainly made of high-grade aluminum silicate ceramic fibers and other formulas by vacuum forming. It has tough texture, high compressive strength, low heat storage and low heat loss. It is suitable for aluminum, copper and zinc centralized melting furnaces, refining furnaces, static furnaces, and electric furnaces. The excellent heat insulation and sealing effect of the water outlet makes the casting process of aluminum-copper-zinc and aluminum-copper-zinc alloy more convenient, safer and more reliable.
