Gunning material is made from high-quality magnesia and high purity magnesia-dolomite clinker inappropriate granularity ratio, it has good sticking ability, low rebounding rate, and high abrasion-resistance. They are widely used in blast furnace body, hot stove body, the protective layer and the lining of piping and flue systems.
Castable is a type of concrete product. A variety of additives is applied to improve the construction ability and water content during construction. A variety of products is used depending on the applications such as float, inflow, and gunning construction. The most common binder used in castables is HAC (high alumina cement). Other binders that are often used include hydratable aluminas and colloidal silica. Castables are mixed with water and then installed by either pouring or pumping. Placement of the material then requires vibration.
Mortar is unshaped refractory, and its main use is adhesive for bricks. Various mortar products are produced according to the characteristic and type of bricks.
Mortar is classified into the air-set mortar, which is hardened at normal temperature after construction, and heat-set mortar, which is sintered at high temperature after construction, and is applicable to the entire area where refractories are used. Wet-type mortar, which is used in the area of non-ferrous metals, is highly appraised for its superior adhesive strength and usage.
The ramming material, with characteristics of small input, strong impact resistance, corrosion resistance and easy on-line maintenance . It has less sintered layers even after a long operation and excellent protection against slag attacks. The quality of dry ramming mass is widely recognized.
Plastic refractories are manufactured with various liquid binders, clay, and water. They’re classified into Patching, Plastic, Ramming, and Stamp according to the quantity of clay and water. Plastic refractories are applied to various types of furnaces such as reheating furnace or induction furnace.
