[0002] The intermediate frequency induction coil is the core component of the intermediate frequency induction coil. At present, the inner lining of the intermediate frequency induction coil on the market is mainly sintered with refractory mud. When the surface cools the sliding bearing, it is difficult to prevent water from splashing onto the inner lining of the induction coil. Such repeated heating-cooling conditions often cause the inner lining of the induction coil fired by refractory mud to burst, which seriously affects the safety of the operation. At the same time, it is often found in the process of use that the induction coil under the condition of cyclic heating and cooling is caused by the expansion of the induction coil and the inner lining fired by refractory mud.

Embodiment Construction
[0026] Taking the induction coil lining used in the ND5 piston pin sleeve as an example, the specific implementation of the present invention will be introduced below.
[0027] Such as figure 1 and figure 2 As shown, the inner lining of the induction coil is formed by nesting cylindrical asbestos boards layer by layer; preferably, the asbestos boards have 3 layers. The inner peripheral surface of the first asbestos board 1-1 located in the inner layer is coated with a water glass adhesive layer 1-2, and the outer peripheral surface is coated with an insulating varnish layer 1-3; the second asbestos board 2 located in the middle layer The inner peripheral surface of -1 is coated with a water glass adhesive layer 2-2, and the outer peripheral surface is coated with an insulating varnish layer 2-3; the inner peripheral surface of the third asbestos board 3-1 located in the outermost layer is coated There is a water glass adhesive layer 3-2, a glass cloth 3-4 is wrapped around ...

Abstract
The invention discloses an induction coil lining and a processing method thereof. The induction coil lining is formed by sleeving cylindric asbestos boards layer by layer; the inner circumference of the inner layer of the asbestos board is coated with a layer of sodium silicate binder, and the outer circumference of the inner layer of the asbestos board is coated with a layer of insulating paint layer; the inner circumference of the outermost layer of the asbestos board is coated with a layer of sodium silicate binder; the outer circumference of the outermost layer of the asbestos board is wound with spun glass cloth, and the outer spun glass cloth is coated with an insulating paint layer. The induction coil lining and the processing method have the advantages that the induction coil lining is made from a material with a completely novel structure instead of the conventional fire clay, so that the induction coil lining is an elastomer and is well matched with the induction coil under the working condition of cyclic heating-cooling; and phenomena such as burst and poor matching performance are avoided, the operation safety is improved, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the field of metallurgy, in particular to an induction coil lining used in the production of steel castings and a processing method thereof. Background technique [0002] The intermediate frequency induction coil is the core component of the intermediate frequency induction coil. At present, the inner lining of the intermediate frequency induction coil on the market is mainly sintered with refractory mud. When the surface cools the sliding bearing, it is difficult to prevent water from splashing onto the inner lining of the induction coil. Such repeated heating-cooling conditions often cause the inner lining of the induction coil fired by refractory mud to burst, which seriously affects the safety of the operation. At the same time, it is often found in the process of use that the induction coil under the condition of cyclic heating-cooling has problems with the cooperation between the induction coil and the inner lining fired ...
