Mineral wool, its manufacture method and its preparation system

Abstract

The invention discloses a mineral wool, its manufacture method and its preparation system, the method for manufacturing the mineral wool comprises the following steps: providing a silicon manganese slag hydrothermal solution and a carbon manganese slag hydrothermal solution, mixing and melting the silicon manganese slag hydrothermal solution and the carbon manganese slag hydrothermal solution to obtain a mixed melt; processing filament on the mixed melt to obtain the mineral wool. According to the manufacture method of the mineral wool, because the silicon manganese slag hydrothermal solution and the carbon manganese slag hydrothermal solution are in a high temperature state, heat energy can be used with the largest limitation, the color of the obtained mineral wool is naturally formed, the obtained color is permanent, the coloring process can be avoided, and the production cost is reduced.

Description

Technical field [0001] The invention belongs to the technical field of mineral wool or slag wool. More specifically, the invention relates to a slag wool and a manufacturing method and a preparation system thereof. Background technique [0002] There are two main types of ceramic fiber products: rock wool and slag wool. From the source of raw materials, rock wool is mainly made of basalt, diabase, granite and other acidic substances, and is obtained by melting with alkali fluxes such as limestone and dolomite. The main composition of acidic materials such as basalt, diabase, granite, etc. is SiO 2 , Al 2 O 3 . [0003] Among them, SiO 2 It is the structural skeleton of rock wool fiber, which improves SiO 2 The content increases the melt viscosity, which is conducive to fiber extension and improves the chemical stability of the fiber in the atmosphere and humid environment, but SiO 2 If the content is too high, it will be difficult to melt and the fiber will become thick. Al 2 O 3...

AI Technical Summary

Problems solved by technology

Although hot charging of blast furnace slag saves some heat energy, it still needs a lot of heat energy to heat and melt the main material in the tempering furnace, which also makes the acidity value of the molten material control lower and more alkaline substances, so that the product has silicic acid Dicalcium Risk

[0005] The inventor found that there are the following deficiencies in the process of research and practice of the prior art: Although the rock wool products produced by using natural raw materials have excellent quality, the production cost is high and the energy consumption is high; Although the slag wool produced by adding acidic materials has been utilized to varying degrees in terms of resources and heat energy, the production cost has been reduced. Although hot charging of blast furnace slag or ferroalloy hot slag liquid saves heat energy, it needs to be heated or melted in the tempering furnace and high temperature furnace. Other materials also require heat energy

In the past, the by-products were treated by quenching silicon-manganese slag hydrothermal solution and carbon-manganese slag hydrothermal solution and providing them to cement plants as raw materials, with extremely low added value.
