Problems solved by technology

[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.

Abstract

The invention discloses cement for an intermediate frequency furnace lining. The cement is prepared from the components in percentage by mass: 70%-80% of dense corundum, 10%-20% of dense corundum powder, 5%-15% of a binder, 0.5%-2% of superfine powder, 0.5%-3% of an additive and 0.1%-5% of an explosion-proof agent. The cement has the characteristics of prolonged service life of the intermediate frequency furnace, high operation efficiency and simple maintenance and adapts to a highly heat environment.

Description

technical field [0001] The invention relates to a cement used for the lining of 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 in the present invention is to provide a kind of cement used for the lining of intermediate frequency furnaces. This cement has a l...
