天津碱厂六十万吨纯碱扩建配套项目自备电站150m烟囱,设计要求内壁牛腿为倒三角形,筒壁内有抗硫酸盐水泥砂浆层、防腐涂层、水泥珍珠岩块隔热保温层、耐火砖内衬共五道工序。通常做法是先滑筒体,然后再搭吊架完成筒内四道工序和牛腿的二次浇灌。这种做法,一般在外筒滑完后,还需3～4个月工期。为缩短工期,工程技术
The 600,000-ton soda ash expansion project of the Tianjin Soda Plant is a self-contained power station with a 150m chimney. The design requires that the inner bulge be an inverted triangle with a sulfate-resistant cement mortar layer, an anti-corrosion coating, and a cement perlite block thermal insulation layer. Firebrick lining a total of five processes. The usual method is to slide the cylinder body first, and then take the hanger to complete the four steps in the cylinder and secondary watering of the calf leg. This practice generally takes 3 to 4 months after the outer cylinder has finished sliding. To shorten the construction period, engineering technology
