Energy-saving roasting process for large-size carbon electrode
The invention provides an energy-saving roasting process for a large-specification carbon electrode. The energy-saving roasting process comprises the following steps: burdening; pressing to form an electrode; roasting and heating; according to the 552-hour energy-saving roasting curve formed by the scheme, the temperature rise time of the curve is short and is shortened by 25% compared with 736 hours of a common roasting curve of a phi1146 electrode; however, the roasted product has the same technical index and use performance as the product with the long roasting curve; the energy consumption of the product is reduced by more than 25%, the roasting capacity is increased by more than 25.0% on the original basis, and the energy-saving short roasting curve is very beneficial to energy conservation and cost reduction of enterprises.
本发明提出一种大规格炭电极节能焙烧工艺，包括配料；压制形成电极；焙烧升温步骤；本方案形成的552小时节能焙烧曲线，曲线升温时间短，比φ1146电极常见焙烧曲线736小时缩短25%；但焙烧的产品与长焙烧曲线产品的技术指标、使用性能相同；产品能耗降低25.%以上，焙烧产能在原基础上增加25.0%以上，节能短焙烧曲线对企业节能、降成本生产非常有利。
