Embodiment Construction
[0035] combined with figure 1 to attach Figure 8 , the water-cooled wall anti-wear fish scale welding method, the water-cooled pipe is anti-wear by using the anti-wear plate and the fish-scale overlapping method successively, including the anti-wear plate and the water-cooled tube a set up side by side, and the water-cooled tube a is a cylindrical tube, so The wear-resistant plate described above includes long strips at the A-end g and the B-end h, and one side of the wear-resistant plate between the A-end g and the B-end h contains an arc i that matches the outer wall of the water-cooled tube a, and the circle On both sides of arc i, end A g is X welding point c, end B h is Y welding point f, X welding point c is on the upper side of the side edge of the wear plate, and Y welding point f is on the side edge of the wear plate The lower side; the welding steps are as follows: step 1, use the ink fountain to level the water-cooled tube a set up side by side. The arc i of the ...

The invention relates to a water wall abrasionproof scale type welding method. Abrasionproof plates are adopted to carry out abrasion prevention on water cooled pipes in a sequential scale type overlapped manner. One side of each abrasionproof plate is provided with circular arc matched with the outer wall of the corresponding water cooled pipe, wherein the two sides of the circular arc are provided with an X welding point and a Y welding point, and the two welding points are arranged on the two sides of the abrasionproof plate. A horizontal line is drawn for the water cooled pipes which are arranged side by side, and the abrasionproof plates intersect with the horizontal line. Frstly, the X welding points of the first abrasionproof plates are subjected to spot welding, then, the X welding points of the second abrasionproof plates are subjected to spot welding sequentially, the multiple abrasionproof plates are sequentially subjected to spot welding, the abrasionproof plates intersect with the horizontal lines and are mutually and partially overlapped, the X welding points of each abrasionproof plate are welded, and then the Y welding points of each abrasionproof plate are welded; or the X welding points and the Y welding points of each abrasionproof plate are sequentially welded. The method using the scheme has the beneficial effects that overlapping gaps of the abrasionproof plates are tight, the welding quality is high, the abrasionproof plates are not prone to disengaging, and the abrasionproof effect is good.
Description
technical field [0001] The invention relates to the technical field of boiler anti-wear, in particular to a water-cooled wall anti-wear fish scale welding method. Background technique [0002] Circulating fluidized bed combustion technology is a clean coal combustion technology highly recognized by the market. It has been widely used and developed at home and abroad for its advantages of high efficiency, low pollution, strong adaptability to coal types, and good load controllability. In the circulating fluidized bed boiler, there will be a large number of high-temperature and high-speed moving material particles that are close to the pipeline. Such particles have strong erosion and wear force. Therefore, how to prevent the water wall of the circulating fluidized bed boiler from wearing out and bursting is the long-term safety. The key to stable operation. [0003] At present, the anti-wear technology of the water wall of circulating fluidized bed boiler mainly adopts the po...
