Production line design: to meet the production demand of 10000 t / a of mechanical casting wholesale, this chapter mainly introduces the design of lost foam production line the selection of relevant equipment. Mechanical casting manufacturers can realize the automation of casting production machinery, reduce labor intensity, improve production efficiency, ensure the coordinated development of product quality environmental protection.
Workshop production program is the basic basis for workshop design. The production program of casting workshop includes: product name output, casting type quality, material part characteristics, quantity of spare parts to be produced quantity of outsourced parts, etc. In this design, the product name is tee pipe, the annual output is 10000 tons, the casting is pipe fitting, the quality requirement is high, the material is gray sheet, the parts have typical symmetrical structure characteristics, etc.
Foamed plastic is a kind of foam. Its texture is very light. It is several times even several times more than that of the same kind of plastic. The foams of foam plastics have the function of preventing air convection, so it is easy to heat transfer play the role of thermal insulation. Therefore, under the action of high temperature liquid metal, its gasification disappearance speed is several times to dozens of times faster than the same kind of plastic. There are many kinds of foam plastics, such as polyvinyl chloride, polystyrene, phenolic resin polyurethane foam.
The three way connections are made of polystyrene foam (EPS). EPS is relatively cheap; it is very easy to form under the requirements of low steam, atmospheric pressure water; the surface of the produced EPS is very smooth; EPS can meet the metallurgical requirements of this process; as the foamed polystyrene has the advantages of small density, rapid gasification, less residue, abundant resources easy processing forming.
