Embodiment

[0020] Embodiment: a kind of unique production method of slag fiber cotton is implemented according to the following steps:

[0021] 1. Use low-grade, difficult-to-separate lean ore magnet powder ore to crush first, and then select high-quality iron concentrate powder through a magnetic separator, and the iron content is more than 62%~65% after testing; the iron concentrate powder + Lime powder + reducing agent + binder, mixed according to the proportion, then rolled and cold-pressed into 18*28*38mm pellets, adding covering agent, entering the tunnel kiln for internal combustion and external combustion (temperature at 1100-1200 ℃ high temperature, so that the metal ball lumps are melted into molten iron and cast into parts).

[0022] 2. The hot liquid slag floating on the melting furnace enters the tempering furnace again, and the acidity coefficient is adjusted to 1.2~1.3. The acidity coefficient of this product is 1.26. The hot liquid slag falls from the outlet gradually, ev...

Abstract

The present invention provides a slag fiber cotton production method, which comprises that: thermal liquid state floating slag in a melting furnace is subjected to re-upgrading, the re-graded slag enters a quenching and tempering furnace, acidity coefficient is adjusted to 1.26, the thermal liquid state slag enters a centrifuge, and inorganic fiber filaments with a diameter of 7 [mu]m are drawn under centrifugal hot wind blowing pressure; when the thermal liquid state slag is blown into the inorganic fiber filaments, a mist-like dust preventing oil agent is blown and sprayed on the inorganic fiber filaments, a water soluble thermosetting type powder phenol formaldehyde resin binder is uniformly sprayed on the inorganic fiber filaments, and wind separation is performed, such that the fibers settles in a cotton collection chamber; and the cotton collection chamber makes the fibers be uniformly distributed on a conveyor belt through the provided negative pressure so as to be output, the material is conveyed into a curing furnace, and pressurization shaping and other processes are performed to prepare the cotton felt and the structure cotton product. According to the present invention, the thermal liquid state slag is directly upgraded to prepare the inorganic fiber filaments, such that the production method is unique, the production cost is low, the production method is superior, the energy sources are circularly and comprehensively utilized and the effects of energy saving and consumption reducing are achieved during the production, and the ecology and the environment are protected.

Description

technical field [0001] The invention relates to slag cotton, in particular to a production method of slag fiber cotton. Background technique [0002] Slag fiber cotton is a kind of mineral wool. Slag fiber cotton is made of smelting industrial waste (slag) as the main raw material. [0003] It has the characteristics of light weight, small thermal conductivity, non-combustible, moth-proof, corrosion-resistant, good chemical stability, and excellent sound-absorbing performance. It can be used for filling, sound absorption, heat insulation, heat preservation and fire prevention in construction projects. [0004] At present, the production method of domestic slag wool and rock wool is: crushing slag and basalt, melting at high temperature, and centrifuging to dry to produce slag and rock wool fiber wool. The disadvantages are: the content and quality of slag and basalt raw materials cannot be self-controlled, and the cost of procurement and transportation is high. [0005] T...
