The casting methods of cast iron tables Small cast iron tables generally use resin sand. On the one hand, it is to facilitate sand removal. There are also the following reasons: 1. Relatively speaking, lost foam casting has great advantages over traditional sand molds for the production of single or small batches of automobile covering parts, machine tool beds and other large molds. It not only saves expensive wood mold costs, but also facilitates operation. , It shortens the production cycle, improves the production efficiency, and has the advantages of high dimensional accuracy, small machining allowance, and good surface quality. 　 2. The resin sand mold has good rigidity and high sand mold strength in the initial stage of casting. This makes it possible to use the graphitization expansion of the cast iron solidification process to effectively eliminate shrinkage and shrinkage defects, and achieve fewer and no risers for gray cast iron and ductile iron. 3. In the production of solid casting, polystyrene foam is used to form furo resin self-hardening sand. When the molten metal is poured into the mold, the foamed plastic pattern quickly vaporizes under the action of the high- temperature molten metal, burns and disappears. The molten metal replaces the original foamed plastic position, and cools and solidifies into a solid casting with the same shape as the pattern. cast iron table Jinggong Measuring Tools Producing Co., Ltd is specializing in manufacturing and exporting all kinds of cast iron products，especially for cast iron floor plates, cast iron surface plates, cast iron clamping plates, cast iron angle plates, cast iron box table and other machine tool castings.

Tempering temperature is 530°C, constant temperature is 2-3 hours, more than 48 hours, the furnace temperature drops below 200°C, the furnace is cooled naturally, and then transferred to the next process. It is machine-added, and leaves the factory after passing the final inspection. Processing process and equipment: Casting: use resin sand lost foam, cupola smelting; take the amount of processing according to the actual situation; the shrinkage rate of the manufacturing casting process is 0.8%, and the anti-deformation amount is 3mm/m; Equipment required: 4mX8m drying kiln, 10T/n, 15T/n, cupola for smelting 10T, 5T, 8T. Hot metal ladle QI-2GAJF, carbon and sulfur combined tester, 100T universal tensile testing machine. For the first time, internal stress is removed, aging temperature is 550 degrees, and equipment required is 4mX8m annealing kiln. Roughing: marking and roughing leave a margin of 5mm. The second time to remove the internal stress is the same as the first time. Finishing: Machining the top and bottom, leaving a margin of 0.2-0.3mm. And processing the surrounding four sides to meet the requirements. Finally, the working surface is finished and chamfered.

Characteristics and methods of castings Casting is a forming method in which molten metal liquid is poured into a mold similar to the shape of the part, and after cooling and solidification, a blank or part with a certain shape and performance is obtained. 1. Casting and its characteristics Castings are generally blanks, which need to be cut before they can become parts. Parts with lower precision requirements and larger surface roughness parameter values, or castings produced by special casting methods can also be used directly. 2. There are many casting production methods, and there are two common types: a. Sand casting: a casting method in which molding sand is used to form compactly. The source of molding sand is wide, the price is low, and the sand casting method is adaptable, so it is the most basic casting method used in production at present. b. Special casting: other casting methods different from sand casting, such as investment casting, metal mold casting, pressure casting, low pressure casting and centrifugal casting. casting of cast iron plates 3. Casting production has the following advantages: a. Can be made into blanks with very complex shapes and cavities. Such as various boxes, beds, racks, etc. b. Wide application range. It can cast workpieces of different sizes, weights and shapes; it is also suitable for different materials, such as cast iron, cast steel, and non-ferrous alloys. The weight of castings can range from a few grams to more than 200 tons. c. Wide sources of raw materials. Scrap parts or chips can also be used; the cost of process equipment is small and the cost is low. d. The size of the obtained casting is close to that of the part. It can save metal consumption and reduce the workload of cutting. However, castings also have disadvantages such as poor mechanical properties, many production processes, unstable quality, and poor working conditions of workers. With the development of casting alloys and casting technology, especially the development of precision casting and the successful application of new casting alloys, the surface quality and mechanical properties of castings have been significantly improved, and the scope of application of castings has been expanding. Jinggong Measuring Tools Producing Co., Ltd is specializing in manufacturing and exporting all kinds of cast iron products，especially for cast iron floor plates, cast iron surface plates, cast iron clamping plates, cast iron angle plates, cast iron box table and other machine tool castings.
