Problems solved by technology
A certain amount of water powder needs to be poured in to pray for the bonding effect, but the water consumption is difficult to control. If the water consumption is too much, a small amount of air bubbles will be generated inside the refractory material during sintering, which will affect the refractory performance. Split

Abstract
The invention discloses a compound additive for a dry type compound furnace lining of an intermediate frequency furnace, which is composed of the following components in percentage by mass: 20-60% sodium tripolyphosphate, 20-60% of boric acid and 10-30% of magnesium lignin phosphate. The compound additive can effectively reduce water consumption, and can prevent a refractory material from shrinking and cracking.
Description
technical field [0001] The invention relates to a composite additive, in particular to a composite additive used for the lining material of a dry-type composite furnace of an intermediate frequency furnace. Background technique [0002] At present, there are a large number of intermediate frequency furnaces with a volume of less than 50 tons for melting alloys. Generally, a single resin-bonded baking and ramming furnace lining is used as the inner lining, but when ramming the refractory lining material used for the intermediate frequency furnace lining. It is necessary to add a certain amount of water powder to pray for the bonding effect, but the water consumption is difficult to control. If the water consumption is too much, a small amount of air bubbles will be generated inside the refractory material during sintering, which will affect the refractory performance. Split. Contents of the invention [0003] The technical problem to be solved by the present invention is t...
