Abstract
The invention belongs to the technical field of casting, and particularly relates to a casting surface box for a large rectangular casting and a manufacturing method of the casting surface box. The casting surface box for the large rectangular casting comprises at least two sand boxes, box belts, horizontal supporting nets, risers, baffles and molding sand, wherein the sand boxes are horizontally distributed above a molding surface at intervals, the box belts are distributed in the sand boxes in a latticed mode, the horizontal supporting nets are arranged between the sand boxes and the molding surface, and the bottoms of the risers abut against the molding surface. One baffle is arranged between two adjacent sand boxes, and the molding surface is filled with the lower end of the molding sand. The casting surface box for the large rectangular casting is manufactured according to actual production, a plurality of existing cover cores are replaced, the operation is easy when the casting surface box is used, sand is not prone to falling off, welding repair of the casting is reduced, and the production efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of casting, and in particular relates to a casting face box for a large-scale rectangular casting and a manufacturing method thereof. Background technique [0002] The quality of the casting has a lot to do with the smooth exhaust of the core during the pouring process. If the exhaust is good, the internal and external quality of the casting can be improved. Poor exhaust will cause the cavity to be suffocated during the pouring process, which may cause serious pouring. The molten steel in the cavity rolls or splashes, making the casting become honeycomb and scrapped. [0003] The production of the existing steel castings generally adopts the production method of the sand box. In this case, there are lower boxes and face boxes. The function of the sand box can effectively prevent the castings from rising and save the amount of molding sand. However, for the production of large-scale castings, due to the larg...
