Abstract
The invention discloses an environment-friendly dry type vibrating material which is characterized by comprising the following raw materials in parts by weight: 45 parts of magnesium stone sand, 51 parts of fused magnesia, 2-5 parts of sodium metasilicate pentahydrate, 2 parts of phenolic resin and 0.2 part of urotropin. The environment-friendly dry type vibrating material has improved bending resistance and pressure resistant strength and favorable high-temperature service performance; through the experiment, the environment-friendly dry type vibrating material has the following performances: at a stage of 220DEG C*24 hours, the volume density is not less than 2.10g/cm<3>, the bending resistant strength is not less than 5.1MPa and the pressure resistant strength is not less than 7.45MPa; and at a stage of 1500DEG C*3 hours, the bending resistant strength is not less than 7.6MPa, the pressure resistant strength is not less than 12MPa and the linear change percentage is -1.9 percent, which can effectively meet the use requirement of refining. In addition, by using the sodium metasilicate pentahydrate, compared with the prior art, the invention can effectively reduce the content of the phenolic resin, that is to say, the invention reduces the content of carbon, thus the environment-friendly dry type vibrating material is more environment-friendly.
Description
Technical field
The present invention relates to a kind of amorphous refractory, especially a kind of environment-protection dry type vibrating material.
Background technology
Existing refractory materials is divided into setting and unsetting two classes, and unshape refractory comprises metallurgical with tundish paint, dry-type vibration material, electric furnace spraying and repairing material and various refractory castablies etc.Existing dry-type vibration material is a main raw material with the magnesia raw material, is made up of the additive and the wedding agent of some amount and proportioning, and this series products adopts the prescription of the dry-type vibration material nineties, the normal usually AL that adopts
2O
3Perhaps micro mist such as SiO2 and solid phenolic resin be as wedding agent, ubiquity that intensity is low, work-ing life not high situation.
Because not only working temperature is higher for each element in the furnace, and bearing molten steel and slag stronger wash away erosion, therefore anti-folding and compressive strength and high temperature use properties are two important indicators of dry-type vibration material, and existing dry-type vibration material can not effectively satisfy the service requirements of furnace.
Summary of the invention
A kind of anti-folding that provides for the deficiency that solves above-mentioned technology and the environment-protection dry type vibrating material that compressive strength increases, the high temperature use properties is good are provided.
In order to achieve the above object, the environment-protection dry type vibrating material that the present invention is designed, it is characterized in that it is made up of the following raw materials in parts by weight proportioning: magnesium is pressed against 45 parts in sand; 51 parts of electrosmelted magnesite clinkers; 2 parts～5 parts of metasilicate pentahydrate sodiums;
2 parts in resol; 0.2 part of urotropine.
As preferably, comprise 20 parts of 5-0mm electrosmelted magnesite clinkers, 31 parts of 180 order electrosmelted magnesite clinkers in described 51 parts of electrosmelted magnesite clinkers.
As preferably, described metasilicate pentahydrate sodium is 4 parts.
As preferably, described magnesium is pressed against sand and is pressed against sand for 5-0mm magnesium.
As preferably, described magnesium is pressed against sand and is pressed against sand for useless magnesium, can further save cost, and described electrosmelted magnesite clinker is 96 electrosmelted magnesite clinkers.
The resulting environment-protection dry type vibrating material of the present invention, anti-folding increases with compressive strength, the high temperature use properties is good, through overtesting, during 220 ℃ * 24h: volume density 〉=2.10g/cm
3, folding strength 〉=5.1Mpa, compressive strength 〉=7.45Mpa; During 1500 ℃ * 3h: folding strength 〉=7.6Mpa, compressive strength 〉=12Mpa, linear change % are-1.9%, can effectively satisfy the service requirements of furnace.In addition, adopted metasilicate pentahydrate sodium,, can effectively reduce the content of resol, promptly reduced carbon content, so the more environmental protection of the resulting environment-protection dry type vibrating material of the present invention than prior art.
