Problems solved by technology

Due to the smelting of tent material, after the bulk material is put into the furnace, the air permeability is poor, the sintering of the material surface is not ideal, and the phenomenon of material collapse often occurs. After the material collapses, the open smelting heat loss is large, the smelting time is long, and the power consumption is high.
And the bulk material contains a large amount of binder asphalt, which contains 70% volatile matter. After the material collapses, a large amount of black smoke and dust will be generated instantly. The fans in the smelting area cannot remove it instantly, causing serious environmental pollution; And there is also a lot of black smoke and dust produced during the furnace pounding process, because coking asphalt contains a lot of toxic and harmful substances, which not only pollutes the environment, but also causes harm to the health of operators

Embodiment 1

[0018] Titanium carbon-based cold tamping material, its raw materials and parts by weight are 55% high-titanium slag, 10% foamed benzene plate particles, 10% crushed graphite, 3% rutile, 2% titanium carbide, 5% boric acid, humic acid Na2SO4 15%; the particle size of the particles in the high titanium slag is 10-15mm, the particle size is 5-10mm, the particle size is 1-5mm and the particle size is the weight fraction below 200 mesh The ratio is 2:1:1:2; the particle size of the crushed graphite is 15-25mm.

[0019] The preparation method of titanium carbon-based cold tamping material, the specific steps are as follows: high-titanium slag, foamed benzene plate, rutile, titanium carbide and graphite crushed into different particle sizes required, after mixing, add binder and boric acid, Put it in a strong stirring pot, 30 rpm, and stir for 30 minutes, so that the materials can stick together through knotting or tamping. The state is the best, and the material can be discharged. ...

Embodiment 2

[0021] Titanium carbon-based cold tamping material, its raw materials and parts by weight are 56% high titanium slag, 8% foamed benzene plate particles, 9% crushed graphite, 2.5% rutile, 2.5% titanium carbide, 6% boric acid, phosphoric acid 16%.

Embodiment 3

[0023] Titanium carbon-based cold tamping material, its raw materials and their weight parts are 60% high-titanium slag, 5% foamed benzene plate particles, 5% graphite crushed, 2% rutile, 2% titanium carbide, 8% boric acid, ring Oxygen resin 18%.

[0024] In order to further study the service life of the furnace cover prepared by the cold tamping material of the present invention, the existing materials were used to tamp the furnace cover, and after long-term smelting, the furnaces with damage to the furnace cover were counted. The results are shown in Table 1.

[0025] Table 1 Statistical results of the use of furnace covers for five kinds of materials cold tamped.

[0026]

[0027] It can be seen that the furnace cover protective layer made of the tamping material of the present invention has a longer service life.

Abstract

The invention belongs to the field of refractory materials and particularly relates to a titanium carbon based cold stamping material as well as a preparation method and an application thereof. The titanium carbon based cold stamping material is prepared from raw materials in parts by weight as follows: 55%-60% of high titanium slag, 5%-10% of foamed benzene board particles, 5%-10% of graphite scraps, 2%-5% of rutile, 2%-5% of titanium carbide, 5%-8% of boric acid and 15%-18% of a binder. The titanium carbon based cold stamping material cannot cause environmental pollution during smelting and is low in cost.

Description

technical field [0001] The invention belongs to the field of refractory materials, and in particular relates to a titanium carbon-based cold tamping material and its preparation method and application. Background technique [0002] In recent years, my country's titanium dioxide and titanium sponge industry has developed rapidly. Due to the high titanium content of high-titanium slag, the production of "three wastes" is small, the utilization rate of resources and energy is high, and it can help improve the quality of products. The high-titanium slag in my country The demand is growing rapidly. In recent years, the annual transaction volume of high-titanium slag in the world has exceeded US$1 billion. High-titanium slag is commonly known as titanium ore enrichment formed through the physical production process. It is a high-content titanium dioxide enrichment obtained after melting and separating titanium dioxide and iron in titanium ore by heating and melting titanium ore in...
