Abstract
The invention discloses a method for producing a baking-free magnesia carbon brick. The method comprises the following steps of: adding 5 to 20 percent of normal-temperature curing agent into thermoset phenolic resin, and uniformly stirring; preparing particle raw materials and powder raw materials used for preparing the magnesia carbon brick according to the conventional proportion; putting the particle raw materials into a mill, adding a binding agent for mixing, and adding the powder raw materials into the mill and continuously mixing to form pug; molding the mixed pug within 60 minutes; placing the molded magnesia carbon brick at room temperature for 36 hours; and performing the conventional test on the magnesia carbon brick to obtain a finished product brick after the magnesia carbon brick is qualified. The method has the advantages that the normal temperature curing agent such as NL or hydrochloric acid and the like are added into the thermoset phenolic resin according to a certain proportion and used as a special binding agent of the magnesia carbon brick, so that the magnesia carbon brick pug can be molded within 60 minutes, and the strength can be built at room temperature within 36 hours; and the magnesia carbon brick can be cured without the conventional method of coal burning, gas burning or electrical heating, so that energy is saved, consumption is lowered and the pollution to atmospheric environment is avoided.
