Abstract
A kind of process for producing magnesium silicate refractory, it is characterized in that: mineral and rock with serpentinite, serpentine matter asbestos tailings, peridotites, rich magnesium silicon components are main raw material, through operations such as broken, 700～1100 ℃ of calcinings down, levigate, moulding, low temperature are synthetic, obtain the refractory products that quality is good, cost is low.
Description
The present invention relates to a kind of production technique of refractory materials, particularly a kind of production technique of magnesium silicate refractory.
In the prior art, be the forsterite fire resistant materials of main raw material with serpentinite, peridotites, in its production technique calcining temperature up to 1400 ℃, even more than, the energy of consumption is a lot, products production cost height.
The purpose of this invention is to provide a kind of mineral and rock with serpentinite, serpentine matter asbestos tailings, peridotites, rich magnesium silicon components is main raw material(s), and production cost is low, the production technique of the low temperature synthetic silicic acid magnesite refractory of good product quality.
Content of the present invention is: a kind of process for producing magnesium silicate refractory is characterized in that being made up of the following step:
A, with the mineral of serpentinite, serpentine matter asbestos tailings, peridotites, rich magnesium silicon components and any one or more the mixture fragmentation in the rock;
B, 700～1100 ℃ of following calcining pretreatment, make starting material dehydrations, activation; With the calcining manners difference, calcination time also can be different;
Wear into fine powder after c, the cooling;
D, add 0～30%(weight % of weight of powdery material again, the back with) magnesia is or/and 0～20% activated magnesia, 4～20% water mix; Add magnesia and can improve refractoriness, add activated magnesia and can strengthen handing over the effect of coagulating;
E, moulding; Can extrusion forming on pressing machine, also can adopt mode moulding such as extruding, compacting, the shape that is become is determined with the need;
F, put into autoclave water vapor steam press maintenance; Water vapor pressure is generally 0.3～10MPa, and steaming pressuring curing system can require and the variation arbitrarily of working condition do with product performance.
Raw material described in the content of the present invention after the fragmentation is calcined down in 700～1100 ℃ after can also wearing into fine powder again, and is no longer levigate after the calcining.
Material described in the content of the present invention after the moulding is put into the autoclave steam press maintenance after can quietly putting for some time again, thereby can improve the performance of fire resistive material product.
Obtaining product drying can also be dried behind the steam press maintenance described in the content of the present invention, seasoning etc.
Compare with existing close forsterite fire resistant materials, the present invention has following characteristics:
(1) the raw materials pretreatment temperature of forsterite fire resistant materials is up to 1300～1500 ℃, the goods firing temperature up to 1500 ℃ about, energy consumption is very high; And the raw material pretreatment temperature is 700～1100 ℃ among the present invention, and goods synthesis temperature (being the steam temperature in the autoclave) only is 100～400 ℃, and energy consumption is very low, and is energy-conservation obvious;
(2) produce the white olivine fire resistive material product and adopt high-temperature sintering process, it is very high to produce the investment of founding the factory; The present invention adopts and steam to press handles, and technology is simple, and it is less to produce the investment of founding the factory;
(3) starting material of the present invention source is very extensive, can utilize industrial by-products in a large number, for example asbestos tailings etc.;
(4) not only quality is good for the refractory materials produced of the present invention, and production cost is significantly less than existing similar technology, and is practical.
