Enviroment friendly dry material formula

Abstract

The invention discloses an environmental protective dry vibrating material formula with the purse of solving the problems that the current dry vibrating material releases harmful gases when in use and poor anti-erosion ability, difficult disintegration and short service life of dry magnesia refractory are easily caused. The environmental protective dry vibrating material formula comprises the components with the following weigh percentages: 5 percent to 10 percent of carbohydrate complex binding agents, 2 percent to 4 percent of sintering agents, 8 percent to 12 percent of antioxidants, 55 percent to 65 percent of magnesia and 18 percent to 22 percent of waste magnesium carbon brick particles. The environmental protective dry vibrating material formula has the advantages that: by introducing carbohydrate complex binding agents, middle-temperature sintering bonding agents and antioxidants, the dry magnesia refractory is good in anti-erosion ability, easy in disintegration and long in service life, does not have toxic and harmful gases and has no pollution to environment.

Description

technical field [0001] The invention relates to an environment-friendly dry material. Background technique [0002] With the development of the iron and steel industry, currently used dry material binders generally use resin to bond dry materials. The advantages are: compared with coatings, the service life is longer, the construction process is simple, and the steel plant has high operating efficiency; the disadvantage is: dry materials are in Harmful gas will be produced during the baking process, and the scope of use is limited. [0003] In view of the harmfulness of resin-bonded dry materials, people have proposed to use sodium phosphate, boron glass, borate, etc. as binders. Although no harmful gas will be produced during use, these binders have low melting points and will As a result, the magnesium dry material has poor corrosion resistance, difficulty in disassembly, and low service life. Contents of the invention [0004] The purpose of the present invention is t...
