[0013] The present invention will be further described below.
[0014] A process for manufacturing a hatch cover for a 10,000-ton container ship, comprising the following steps:
[0015] A. Manufacture tire frame. The tire frame is the basis for hatch cover accuracy assurance. Due to the foundation settlement of the production site, the level error of the tire frame is large. Before construction, the tire frame level should be corrected, requiring ±1mm to ensure the assembly of the hatch cover. Accuracy, according to the product, the tire frame is reasonably divided to maximize the utilization rate;
[0016] B. Lofting and blanking. Since more than 90% of the materials used in the hatch cover are thin plates below 10mm, it is difficult to control the welding shrinkage and deformation. According to the company's production conditions and characteristics, combined with the past production experience of similar products, the The shrinkage allowance is refined to each part of the...
