There are many iron material brands that are suitable for casting in an iron casting manufacturer, depending on the specific application and requirements. Some of the most common brands used in iron casting include:

These listed materials offer a range of properties that can be tailored to specific applications, making iron casting a versatile manufacturing process.

According to the formation mechanism of sand inclusions, the occurrence of sand inclusions can be prevented from the following aspects:

(1) The correct selection and preparation of molding sand is the main measure to prevent sand inclusion in iron casting manufacturers. If quartz feldspar sand with a small coefficient of thermal expansion is selected as the original sand. Major castings use special sand with low thermal expansion coefficient, no phase change, high thermal diffusion rate, and high thermal storage coefficient as the raw sand. Select raw sand with dispersed particle size (preferably distributed on five adjacent sieves).
Choosing bentonite with high hot wet tensile strength and low hot compression stress, increasing the amount of bentonite added, can improve the anti sand inclusion ability of molding sand. Adding coal powder, heavy oil, wood chips, etc. to the molding sand can reduce thermal stress; Minimize the moisture content of the molding sand as much as possible to ensure the mixing time; The mixed sand, after being evenly mixed and loosened, has a good effect on maintaining stable sand performance and preventing sand inclusion.

(2) In terms of casting technology, avoid pouring large flat surfaces in a horizontal position: the iron casting manufacturer’s pouring system should be able to allow the metal liquid to smoothly enter the mold cavity, and the internal runners should be evenly distributed to prevent local overheating; Increase the blocking area of the sprue appropriately to quickly seal the surface of the baked mold; Reduce the pouring temperature appropriately.
The iron casting manufacturer uses high-strength molds such as sodium silicate sand, limestone sodium silicate sand, resin sand, etc., which can effectively prevent sand inclusion.
The shape requires that the compactness of the molding sand should be uniform, avoiding local hardening or looseness; In areas prone to sand inclusion such as the upper surface and near the pouring channel, more air holes should be drilled to reduce gas pressure, and local reinforcement should be carried out by inserting nails; Dry the surface of the sand mold to improve surface strength.

(3) In terms of casting structure, try to avoid large flat surfaces and ensure that the casting angles are appropriate. The ability of different shaped cavities to resist sand inclusion varies, with concave shapes having the best resistance, followed by flat shapes, and convex shapes having the worst resistance. When conducting process design, iron casting manufacturers should take necessary measures for convex shaped cavities to prevent sand inclusion.
