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.

Description

Exempt to toast the production method of magnesia carbon brick
Technical field
The present invention relates to the production method of magnesia carbon brick, especially relate to a kind of production method of exempting to toast magnesia carbon brick.
Background technology
Used magnesia carbon brick on the Thermal Equipments such as steel-making ladle, hot metal ladle, electric furnace, its conventional production method generally need be carried out drying treatment under 160~245 ℃ temperature, through 48~80 hours, after making resin solidification and setting up intensity, place again about 12 hours and just can choose, pack.This method not only the production cycle long, labor strength is big, when dry need with methods such as fire coal, combustion gas or electrically heated also can waste energy contaminate environment.
Summary of the invention
The object of the present invention is to provide a kind of high efficiency, labor strength is low and the production method of exempting to toast magnesia carbon brick of save energy.
For achieving the above object, the present invention can take following technical proposals:
Production method of exempting to toast magnesia carbon brick of the present invention, it comprises the steps:
The first step adds 5~20% ambient cure agent in heat-reactive phenolic resin, it is standby as wedding agent to stir;
Second the step, routinely ratio prepare the used particulate material of magnesia carbon brick and powder raw material standby;
The 3rd step, the magnesia carbon brick particulate material is put into the stone roller machine, add the wedding agent that the first step prepares according to 3.2% of total raw material, mixing 2~5 minutes, powder raw material is added continue to become in mixing 7~15 minutes the magnesia carbon brick pug in the stone roller machine again;
In the 4th step, the 3rd magnesia carbon brick pug that mix of step is transported to the moulding in 60 minutes of pressure board finishes;
In the 5th step, the room temperature after visual testing of the magnesia carbon brick after the moulding was placed 36 hours;
The 6th step, will place 36 hours magnesia carbon brick by batch carrying out conventional physics, Chemical Analysis, be finished bricks after qualified.
Used ambient cure agent is NL or hydrochloric acid.
The invention has the advantages that ambient cure agent such as NL or hydrochloric acid are added in the heat-reactive phenolic resin into (Re solidity Fen aldehyde Shu Zhi ﹕ ambient cure agent=100 ﹕ 5~20) by a certain percentage as the extraordinary wedding agent of magnesia carbon brick, can guarantee the moulding in 60 minutes of magnesia carbon brick pug, set up intensity in room temperature in 36 hours, do not need to adopt ordinary methods such as fire coal, combustion gas or electrically heated to impel magnesia carbon brick to solidify, not only accomplished to save energy and reduce the cost, also avoided pollution atmospheric environment.
