Description
Technical Field
The invention relates to the technical field related to casting, in particular to a casting device and a casting method of a steel pipe for a building.
Background
Casting is a metal hot working process which is relatively early mastered by humans and has been known for about 6000 years. China has entered the full bloom of bronze castings between 1700 and 1000 years before the first official metase, and has reached quite high levels in technology. Casting refers to a processing mode of pouring solid metal into a casting mold with a specific shape after solidification. The cast metal comprises: copper, iron, aluminum, tin, lead and the like, and the materials of the common casting mold are raw sand, clay, water glass, resin and other auxiliary materials. The special casting mold comprises: investment casting, lost foam casting, metal mold casting, ceramic mold casting, and the like. (the raw sand includes quartz sand, magnesia, zircon sand, chromite sand, forsterite sand, orchid stone sand, graphite sand, iron sand, etc.). Casting-smelting metal, making casting mould, pouring molten metal into casting mould, solidifying and obtaining the invented forming method of metal part blank with a certain shape, size and performance. The casting is a technological process of smelting metal into liquid meeting certain requirement, pouring the liquid into casting mould, cooling, solidifying and cleaning to obtain the casting with preset shape, size and performance. Casting is one of the basic processes of the modern device manufacturing industry, with the goal of avoiding machining or minor machining due to near forming of the cast blank reducing costs and manufacturing time to some extent.
Mainly comprises sand casting and special casting 2 kinds.
1. Common sand casting uses sand as a casting material, also known as sand casting, foundry sand, including green sand, dry sand, and chemically hardened sand mold type 3, but not all sand may be used for casting. The advantage is lower cost, because the sand used by the casting mould can be reused; the disadvantage is that the mould is time consuming to manufacture, the mould itself cannot be reused, and the finished product can be obtained after being destroyed.
2 special casting, according to molding materials, can be divided into two types of special casting (such as investment casting, mud casting, shell casting, negative pressure casting, full mold casting, ceramic mold casting and the like) which takes natural mineral sand as a main molding material and special casting (such as metal mold casting, pressure casting, continuous casting, low pressure casting, centrifugal casting and the like) which takes metal as a main molding material.
