Low-cost high-density graphitized carbon block and preparation process thereof
The invention relates to a low-cost high-density graphitized carbon block and a preparation process thereof. The low-cost high-density graphitized carbon block is prepared from the following raw materials: sponge coke with the particle size of 6-9mm; the particle size is less than 0.5 mm; shot coke with the particle size of 0.5-6 mm; the particle size of the shot coke is less than 0.5 mm; the pellet coke is calcined for 1-5 minutes at the temperature of 1300-1500 DEG C and is calcined for 1-5 minutes at the temperature of 1900-2200 DEG C before being crushed. According to the invention, a large amount of projectile coke which is not used in the traditional graphitized cathode carbon block production is adopted, the use bottleneck of the projectile coke is solved, and the production cost is reduced. An optimal material particle size ratio of the sponge coke to the shot coke and a mixing and forming process are adopted; in combination with an exclusive roasting heating curve, excellent strength, thermal conductivity, resistivity, sodium permeation expansion rate and finished product rate are realized; and the cathode material is very suitable for being used as a cathode material of an electrolytic cell and can completely meet industrial low-cost batch production requirements.
本发明一种低成本高密度石墨化炭块及其制备工艺，由以下原料制备而成：粒径6～9mm海绵焦；粒径＜0.5mm海绵焦；粒径0.5～6mm弹丸焦；粒径＜0.5mm弹丸焦，煤沥青；弹丸焦粉碎前经过1300℃～1500℃煅烧1～5分钟，1900℃～2200℃煅烧1～5分钟。本发明大量采用了传统石墨化阴极极炭块生产中不用的弹丸焦，解决了弹丸焦使用瓶颈，生产成本得到了降低。采用了最优的海绵焦和弹丸焦的料粒度配比，以及混合成型工艺；结合独家的焙烧升温曲线，实现了优良的强度、导热率、电阻率，钠渗透膨胀率，成品率；非常适合作为电解槽的阴极材料使用，能够完全满足工业化低成本批量生产需求。
