Embodiment approach

[0043] According to a preferred embodiment of the present invention, the preparation method of the special coke for the ceramic fiber vertical melting furnace includes: mixing the blended coal and the binder and then performing dry distillation; the dry distillation process includes: first heating up to the Require dry distillation temperature, then carry out constant temperature dry distillation; The weight ratio of described mixed coal and binder is 100:2-12;

[0044] The blended coal includes coking coal, fat coal, 1 / 3 coking coal and lean coal; based on the total amount of the blended coal, the coking coal content is 40-85% by weight, and the fat coal content is 10-15% by weight %, the 1 / 3 coking coal content is 0-30% by weight, and the lean coal content is 5-15% by weight;

[0045] Wherein, the binder satisfies: the content of β resin is 25-30% by weight, the content of γ resin is 64-75% by weight, and the content of α resin is 0-6% by weight; the binder has the following...

Embodiment 1

[0062] After mixing the blended coal and binder, carry out dry distillation to obtain special coke for ceramic fiber vertical melting furnace; the dry distillation process is as follows: firstly, heat up from room temperature at 1°C / min to 1050°C (i.e. dry distillation temperature), and then carry out constant temperature Dry distillation 170h. The weight ratio of the blended coal to the binder is 100:4.9. The indicators of the mixed material of the blended coal and binder are shown in Table 2.

[0063] Among them, the composition of blended coal is: 45.5% by weight of Xinjing (i.e. coking coal), 36.5% by weight of Xinyuan (i.e. 1 / 3 coking coal), 12% by weight of Xinsheng 2# (i.e. fat coal), 6% by weight of New promotion 9+10# (that is, lean coal). The blended coal has a particle size distribution: based on the total amount of blended coal, the part with a particle size of ≤0.5mm accounts for 8% by weight, the part with a particle size of 0.5-1mm accounts for 57% by weight, ...

Embodiment 2-4

[0068] According to the method of Example 1, the difference is that the binders are different, specifically the binders shown in Table 1 are used. The test results are shown in Table 2.

Abstract

The invention relates to the technical field of production of special coke for ceramic fiber vertical melting furnaces, and specifically discloses a preparation method of special coke for ceramic fiber vertical melting furnaces, special coke for ceramic fiber vertical melting furnaces and its application. The method includes: dry distillation after mixing the blended coal and the binder; wherein, the binder satisfies the following requirements: β resin content is 25-30% by weight, γ resin content is 64-75% by weight, and α resin content is 0-6% by weight . The present invention can increase the special coke size for ceramic fiber vertical melting furnaces while ensuring the quality of special coke for ceramic fiber vertical melting furnaces by using blended coal and a binder with a specific composition, as well as other technical features. The yield of lump coke (particle size ≥ 80mm) and other quality indicators meet the standards for coke used in ceramic fibers; the method is simple in process, does not require new equipment, and reduces the cost of coal blending.

Description

technical field [0001] The invention relates to the technical field of production of special coke for ceramic fiber vertical melting furnaces, in particular to a method for preparing special coke for ceramic fiber vertical melting furnaces, special coke for ceramic fiber vertical melting furnaces and applications thereof. Background technique [0002] Ceramic fiber products usually use high-quality basalt, dolomite, etc. as the main raw materials. After the agent is collected by the cotton collector, the pendulum method is used, and the cotton is laid by the three-dimensional method, and then solidified and cut to form ceramic fiber products of different specifications and uses. The equipment for ceramic fiber production is generally a vertical melting furnace, which is a vertical furnace. For the production of ceramic fibers, the most important thing is stable furnace conditions. First, the material level in the furnace is stable, and second, the temperature in the furnace...
