Monolithic Refractory

  • Electric furnace gunning material

    Electric furnace gunning material

    During the smelting process, the gunning material for electric furnace is subjected to the same high temperature and harsh working environment as the lining of the repaired furnace. Therefore, the gunning material should not only have high fire resistance, corrosion resistance, erosion resistance, spalling resistance, etc., but also must be Furnace repair lining has good adhesion.

  • Insulating Castable Refractories

    Insulating Castable Refractories

    Insulation refractory castable have light bulk density, low thermal conductivity, high strength, uniform air tightness, and are resistant to acids and alkalis. It is suitable for the furnace body, furnace wall and furnace roof of medium and low temperature thermal equipment. After being cast on site, the insulation layer becomes a whole and the insulation performance is enhanced. It is used on various power station boilers and industrial kilns. Excellent heat insulation and energy saving effect.

  • Plastic Castable

    Plastic Castable

    Plastic castable is made of high alumina bauxite clinker, corundum, mullite and silicon carbide as aggregates or powders, and is formulated with different binders and additives, and has high wear resistance. A type of unshaped refractory, a refractory made of 70% to 80% granular and powdery materials, 10% to 25% of plastic clay and other binders, and an appropriate amount of plasticizer.

  • Low Cement Castable

    Low Cement Castable

    Low cement castable refers to a castable with a lower amount of cement. The cement dosage of refractory cement castables is generally 15% to 20%, and the cement dosage of low cement castables is about 5%, and some even reduce to 1% to 2%. The purpose of reducing the amount of cement is to improve the fire resistance of the castable.

  • Refractory Mortar

    Refractory Mortar

    Refractory mortar consists of refractory powder, binder and admixture. Almost all refractory raw materials can be made into powder used to prepare refractory mortar. The ordinary refractory clay made by adding refractory clinker powder and an appropriate amount of plastic clay as a binder and plasticizer is called ordinary refractory clay, which has low strength at room temperature, and high strength is formed by ceramic bonding at high temperatures. The chemically bonded refractory clay, which uses hydraulic, air-hardened or thermosetting bonding materials as the bonding agent, produces a certain chemical reaction and hardens before it is lower than the ceramic bonding temperature.

  • Precast Block

    Precast Block

    Precast block also known as unshaped refractory prefabricated block, is mainly made of refractory castable and refractory plastics. Its classification includes castable prefabricated block and plastic prefabricated block; there are aluminate cement, water glass, Phosphoric acid and aluminum phosphate, clay binding and low cement binder prefabricated blocks; according to the type of aggregate, it is divided into high alumina, clay, siliceous and corundum prefabricated blocks; according to the molding method, it is divided into vibration molding and vibration compression molding And ramming and forming prefabricated blocks; the mass of prefabricated blocks is dozens of kilograms to several tons, so they are divided into large, medium and small prefabricated blocks; the prefabricated blocks are equipped with steel bars and anchors, so they are divided into ordinary prefabricated blocks and steel prefabricated blocks. Blocks and anchors prefabricated blocks, etc.

  • Castable Refractories

    Castable Refractories

    Castable refractories are kind of granular and powdery materials made of refractory materials, and a certain amount of binder and moisture are added together. Castable refractories have high fluidity and is suitable for construction by casting method. It is an unshaped refractory that can be hardened without heating. The refractoriness is similar to that of refractory bricks of the same texture, the load softening point is slightly lower than that of refractory bricks, and the overall performance is better than refractory bricks. The castable has higher compressive strength at room temperature due to the effect of low temperature on the binder. Due to the good integrity of the masonry, the airtightness of the blast furnace is good, it is not easy to be deformed, and its resistance to machine vibration and impact is better than that of brick masonry.

  • High Strength Castable Refractories

    High Strength Castable Refractories

    High strength castable refractories are kinds of cement based composite single component dry mortar, which is prepared by industrial production of high strength cement, mineral admixture, high strength aggregate and anti-crack wear-resistant agent.

    High strength castable refractories can be used by adding water and stirring on site. It has good construction and work ability. A certain thickness of anti-wear layer is formed on the surface of the silo or ore trough by manual plastering. After normal maintenance, it can meet the technical requirements and has abrasion resistance. High, high bonding strength with basic concrete (steel silo), strong impact resistance, high compressive strength, good durability, long service life, etc.
