[0002] At present, there are a large number of intermediate frequency furnaces used for smelting alloys and heating annealing in our country. Some of them use silicon carbide as the lining or use a single resin combined with cement for the protection and insulation of intermediate frequency furnace coils. Easy to break, short service life, high frequency of replacement, inconvenient, high energy consumption, and insufficient protection for intermediate frequency furnace coils
Moreover, the labor intensity of workers is too high for each repair and maintenance, and it is easy to cause many unsafe factors in a high-heat environment.

[0017] The technical scheme of the present invention is: a kind of preparation method of cement for intermediate frequency furnace, comprises the following steps:
[0018] A. Evenly mix the raw materials consisting of dense brown corundum, dense brown corundum fine powder, binder, superfine powder, additives and anti-knocking agent;
[0019] B. Put the mixed raw materials into the forced mixer for stirring. After stirring evenly, add additives and stir evenly. When using, add a certain proportion of water and stir evenly. The evenly formed cement should be spread around the coil;
[0020] C. After construction, it should be dried naturally for 4 hours in order to complete the hydration reaction process. During partial renovation, it should be dried naturally for 1 hour to facilitate the full volatilization of water, ensure the inter-turn and overall insulation of the intermediate frequency furnace coil, and make it have the corresponding strength.
[0021] In the present inv...

Abstract
The invention discloses a preparation method of cement gum for an intermediate frequency furnace. The preparation method comprises the following steps: first, uniformly mixing raw materials formed by compact brown aluminum oxide, compact brown aluminum oxide fine powder, a bonder, superfine powder, an additive and a detonation inhibitor; then, stirring the mixed raw materials and plastering the uniformly stirred cement gum around a coil; finally, after construction, naturally drying to complete hydration reaction to ensure the turn-to-turn and integral insulativity of the coil of the intermediate frequency furnace, wherein the coil has corresponding strength. The cement gum prepared by the method is long in furnace life, high in work efficiency, simple to maintain and suitable for a high-heat environment.
Description
technical field [0001] The invention relates to a preparation method of cement for an intermediate frequency furnace. Background technique [0002] At present, there are a large number of intermediate frequency furnaces used for smelting alloys and heating annealing in our country. Some of them use silicon carbide as the lining or use a single resin combined with cement for the protection and insulation of intermediate frequency furnace coils. Easy to break, short service life, high replacement frequency, inconvenient, high energy consumption, and insufficient protection for intermediate frequency furnace coils. Moreover, the labor intensity of workers is too large when repairing and maintaining each time, and it is easy to cause many unsafe factors in a high-heat environment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for preparing the clay for intermediate frequency furnaces. The clay has a long ...
