Induction Coil Red Mud

中频感应炉tion coil insulation red mud: designed to protect the core of the coreless induction furnace coil and the inner surface of the coil to protect the material. Insulate and delay the deformation of the coil. It has the characteristics of high strength, high density, high insulation, etc., which can effectively prevent the occurrence of coil ignition breakdown caused by the turn-to-turn short circuit of the coil; and can block the penetration of molten metal and other harmful substances in a certain period of time.

The high-purity fused corundum material is selected as the main raw material, and the coil insulating red mud has a good viscosity, and the smear is also very convenient to apply the smooth surface formed on the coil, which can buffer the expansion and contraction of the working lining. It can be used as a coating. It can be used as a casting after appropriately increasing the water content by 0.5%-1%. It has excellent construction performance, high strength and high wear resistance. The addition of organic fibers to the material greatly reduces the drying time. The material is red to distinguish it from the color of the work lining.

Designed as a coating protection material for the core of the coreless induction furnace coil and the inner surface of the coil. The coil red mud is also called coil cement and coil mud, and has the characteristics of high strength, high density and high insulation. Insulation, heat insulation and delaying the deformation of the coil can effectively prevent the occurrence of short circuit between the turns of the coil; and can block the penetration of molten metal and other harmful substances for a certain period of time.

Construction Process

A lead hammer is placed in the center of the intermediate frequency furnace to check whether the coil is concentric with the furnace at the bottom or other parts.

When applying the coil red mud to the coil, use a boring tool to smash the material between the coils to ensure that the material is in place.

平均10 - 15毫米厚线圈赤泥应用于the inner surface of the coil to make the surface of the coil red mud concentric with the coil.

When the coil red mud begins to solidify, use a wire brush to gently scrape the surface of the coil red mud to help dry.

When repairing the coil red mud, first clean all the insulation materials on the coil red mud.

After the construction is completed, it is naturally dried for 8 hours, and then dried by an external heating source at a temperature of 100-410 ° C for about 24 hours. After the coil red mud is completely dried, the lining can be applied.

When the coil red mud is dried, gas or electric furnace can be used to avoid direct contact of the flame with the red mud of the coil, and avoid using a heater that is not sufficiently burned by a spray gun to prevent conductive impurities such as char from entering the coil red mud. Baking with hot air is the best choice.
