Abstract
The invention relates to a method for preparing glass fiber from liquid blast furnace slag as a main raw material. The method comprise the following steps of proportioning liquid blast furnace slag, solid sodium silicate, limestone, fluorite and boron trioxide at a certain mass ratio, melting and drawing to obtain glass fiber. The method has the characteristics of simple process, low energy consumption, high additional value of the product, high comprehensive utilization rate of slag and the like and is suitable for industrial production.
Description
Technical field
The present invention relates to a kind of method utilizing melting blast-furnace slag to prepare glass fibre, belong to field of inorganic nonmetallic material.
Background technology
The slag of discharging in blast furnace ironmaking process, also known as blast-furnace slag, different according to ore grade, often refine 1t iron and discharge 0.3t ~ 1t slag, ore grade is lower, and bed drain purge is larger.It is reported, the whole nation is annual discharge blast furnace slag 100,000,000 about t at present, and along with the development of China's Iron And Steel Industry, the quantity discharged of blast furnace slag increases day by day.If these slags not recycling treatment in addition, the significant wastage of still available stock, does not accumulate over a long period and occupation of land certainly will be caused to invade a series of serious problems such as field, contaminate environment.At present, due to environment, energy-conservation and the requirement of aspect such as to reduce costs, there is a lot of operation and utilized company and the factory of blast furnace slag.The utilization of blast furnace slag is all paid much attention to the research on secondary resource comprehensive utilization technique in U.S., day, method, English, Germany Deng Guo Steel Plant, substantially reaches deslagging and utilizes balance.With regard to existing state of the art and producing level, blast-furnace slag is used as material of construction and mainly comprises the following aspects: 1. for cement, concrete mixture.Baosteel now builds the factory that is produced per year 600,000 t slag micropowders, and its product can substitute the cement in concrete; 2. slag rubble is produced; 3. for the preparation of non-burning brick; 4. operating mine slag wool etc.
Because glass fibre has the excellent performance such as large, high temperature resistant, the unique electrical insulating property of intensity and good dimensional stability, have a wide range of applications in matrix material, Reinforced Rubber, abrasives, materials for wall, high-temperature resistant fabric, electronics and electric material etc.Since entering 21 century, China's fiber glass industry has had significant progress, and China has become world's glass fibre first big producing country, has very important status in the world.With melting blast-furnace slag for the principle meeting recycling economy " minimizing, recycling, resource utilization " completely of glass fibre prepared by raw material.
Current application number be 201010274345.8 patent of invention propose a kind of method that molten blast furnace slag directly makes devitrified glass, the method is with liquid blast furnace and melt of si O
2for main raw material, add in batching stove by certain mass ratio and mix; The compound prepared is transferred to heat treatment furnace by stove of preparing burden heat-treat, room temperature is annealed to gains, obtain devitrified glass.
The present invention is different from above-mentioned report, for the composition characteristic of blast-furnace slag, propose a kind of method preparing glass fibre using melting blast-furnace slag as main raw material, product is made to have higher added value, and have that technique is simple, cost is low, comprehensive utilization of slag rate high, be suitable for suitability for industrialized production.The oxide compound composition of each raw material involved in the present invention is as shown in table 1.
