Aluminium alloy Polishing and Shot Blasting old vacuum sand casting parts.
Description
Sand casting refers to a casting method in which castings are produced in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting methods.
The basic raw materials for making sand molds are foundry sand and sand binder. The most commonly used foundry sand is siliceous sand. When the high-temperature performance of silica sand cannot meet the requirements of use, special sand such as zircon sand, chromite sand, and corundum sand are used. In order to make the finished sand mold and core have a certain strength and not be deformed or damaged during handling, molding and pouring of liquid metal, it is generally necessary to add a sand binder in the casting to bond the loose sand particles to form sand. The most widely used molding sand binder is clay, and various drying oils or semi-drying oils, water-soluble silicates or phosphates and various synthetic resins can also be used as molding sand binders. The outer sand molds used in sand casting are divided into three types: clay green sand, clay dry sand and chemical hardened sand according to the binder used in the sand and the way it builds its strength.
The advantages of clay green sand casting are:
①The clay is rich in resources and cheap.
②Most of the used clay wet sand can be recycled and reused after proper sand treatment.
③The cycle of manufacturing the mold is short and the work efficiency is high.
④The mixed molding sand can be used for a long time.
⑤After the sand mold is pounded, it can still tolerate a small amount of deformation without being damaged, which is very beneficial for drafting and core setting.
