根据莱钢焦化厂改质沥青生产工艺的特点和存在问题，自主设计并采用了全自流改质沥青的生产工艺，实践结果表明，新生产工艺优化了反应釜加热炉炉体的结构，解决了造成改质沥青液下泵使用寿命较短的关键性技术难题，提高了生产开工周期，降低运行成本。%According to the characteristics and problems about production technology of the modified bitumen, designed and used a full self - gravity production technology. The experimental results Showed that new production technology optimized the structure Of the heating furnace of the reactor, resolved the key technical problems of the resulting modified asphalt liquid pump shorter service life , improved the production operating cycle, reduced operation cost.
