中部槽焊接预热

Preheating for middle groove plate welding

 

1.产品概述与使用方法:Product overview and usage 

中部槽板需要承载着矿石或煤炭从矿坑底部运到地面,所以槽板和帮板的焊接必须牢固且耐冲击。我们设计并制造了双火焰加热平台,专门针对中部槽的槽板和帮板焊前预热。直排多火口加热炬的方向可以调节,两排加热炬之间的距离可以调节,完美地满足了不同尺寸中部槽焊接的要求。多火口交叉排布,使火焰有效覆盖在焊缝两边,保证焊缝周围受热均匀,防止焊接过程中氢致裂纹产生保证焊接工艺的实施,也就保证了焊接质量。加热平台配备了PLC操控系统,可以由操作人员一键启动,也可与自动焊接生产线匹配使用。

The middle groove plates need to carry ore or coal from the pit bottom to the ground, so the welding of the groove plates and the edge plates must be strong and impact resistant. We design and manufacture a double-row flame heating platform specifically for preheating the grooved and edge plates. The direction of the inline multi-nozzle heating torch can be adjusted, and the distance between the two rows can be adjusted, which perfectly meets the requirements of middle groove welding with different sizes. Multi-nozzle cross-arrangement can have the flame effectively covering both sides of the welding seam, to ensure that the welding seam and its surroundings are evenly heated up, to prevent hydrogen cracks, to ensure the implementation of the welding process, and to ensure the quality of welding. The heating platform is equipped with a PLC control system, which supports one click on. This system also could be used in conjunction with the automatic welding production line.
