钛钢复合板生产工艺
目前执行的国家新环保规定中，要求新建火力发电厂工程必须同时安装烟气脱硫设施，薄复层钛钢复合板在电厂烟囱领域的使用，为电厂烟囱的防腐设计提供了新的思路和经验，并取得了巨大的经济效益。从国内和国际钛钢复合板的生产情况看，主要由三条钛钢复合板复合板生产工艺，即爆炸复合法、直接轧制复合法、爆炸-轧制复合法。
a、爆炸复合法，直接通过爆炸焊接生产钛钢复合板复合板的工艺方法，这种工艺生产的复合板爆炸面积不大，比较成熟的爆炸工艺复材厚度必须为1.5～12㎜，面积不大于10㎡，且钛钢复合板存在拼焊缝；
b、直接轧制复合法，直接通过轧机强大的轧制力生产钛钢复合板的工艺方法，这种工艺方法可直接生产出大面积、无焊缝钛钢复合板复合板，但需选用合适的夹层材料，对轧制力（大于9000t）、加热温度、真空除污、叠合方式等技术要求高，目前国内厂家很少采用此种工艺；
c、爆炸-轧制复合法，先通过爆炸制坯，再将坯料加热轧制生产钛钢复合板的工艺方法。这种方法可得到大面积无焊缝薄复层金属复合板，效率高、质量稳定，工艺简便易行，但宽幅轧机是关键设备，否则无法实现。
Titanium steel composite plate production process
At present, the implementation of the new national environmental regulations, requiring new thermal power plant project must be installed at the same time flue gas desulfurization facilities, thin multilateral titanium steel composite panels in the power plant chimney areas for the power plant chimney corrosion design provides a new way of thinking and experience , And achieved huge economic benefits. From the domestic and international titanium steel composite plate production situation, mainly by the three titanium steel composite plate composite plate production process, namely explosive compound method, direct rolling compound method, explosion - rolling compound method.
a, explosion compound method, directly through the explosive welding production of titanium steel composite board composite board process method, the production of composite board blast area is not large, relatively mature explosion process complex thickness of material must be 1.5 ~ 12 mm, the area is not More than 10 square meters, and titanium steel composite panels exist welding seam;
b, direct rolling compound method, directly through the rolling mill strong rolling force of titanium composite plate production process, this process can directly produce a large area, no weld titanium steel composite board composite board, but the need to choose the right Of the sandwich material, the rolling force (greater than 9000t), heating temperature, vacuum decontamination, stacking and other technical requirements, the domes
tic manufacturers rarely use this technology;
C, explosion - rolling compound method, first through the billet explosion, and then the billet heated rolling production of titanium steel composite plate process. This method can be a large area without weld thin clad metal composite panel, high efficiency, stable quality, easy process, but the wide mill is the key equipment, otherwise cannot be achieved.
