Embodiment 1
[0046] refer to figure 1 — Figure 4 , a kind of green silicon carbide reactive mixture, comprising the following materials by weight:
[0047] Add 0.2 parts by weight of quartz sand, 0.18 parts of petroleum coke, 0.2 parts of silicon carbide return charge, and 0.5 parts of fine crystals to 1 part by weight of roasting material;
[0048] The SiO of the quartz sand 2 Content≥99.3%, Al 2 o 3 Content≤0.3%, Fe 2 o 3 Content ≤ 0.2%, CaO content ≤ 0.1%, Ignition content ≤ 0.2%;
[0049] The fixed carbon of the petroleum coke is ≥ 90%, the ash content is ≤ 0.8%, the volatile content is ≤ 7%, and the sulfur content is ≤ 1%;
[0050] The calcined material is obtained after the front round green silicon carbide synthesis reaction, wherein the Sic content is 20%, SiO 2 Content 25%, Al 2 o 3 content 2%, MgO content 0.03%, CaO content 0.6%, Fe 2 o 3 Content 0.05%, F·C content 5%, NaCl content 0.1%;
[0051] The SiO of the silicon carbide return charge 2 Content ≥ 90%, F·C c...
