Fused Ceramic Sand Plays an Important Role in Foundry Industry
As the basic industry of equipment manufacturing, fused ceramic sand plays an important role in the development and application of national economy. The total output and demand of castings are increasing year by year. The industry benchmark enterprises in the field of metal casting and surface treatment always pay attention to technology research and development, and constantly introduce new products and technologies to meet the requirements of customers, more and more foundries use fused ceramic sand as a new molding sand material.
We all know that fused ceramic sand is a black round spherical sand, so why is the color of fused ceramic sand black?
Color is one of the important optical properties of minerals, and can also be used as a mineral identification feature. White is the natural color of the mineral. If there are impurities in the mineral, it will show another color different from white. For example, bauxite presents light yellow and brown yellow. After high temperature, because it contains pigment ions such as Ti and Fe, the color of fused ceramic sand is different according to the content of pigment ions, and it will appear dark brown and black.
Sanmenxia Qiangxin Foundry Material Co., Ltd. specializes in the production of fused ceramic sand - a new type of casting sand. It is resistant to high temperature, easy to collapse, small thermal expansion, good regeneration performance, smooth surface, high casting precision, and non- sticking sand. It has good casting performance and is recognized by casting experts at home and abroad.
Fused Ceramic Sand Applications
Fused ceramic sand is suitable for various casting methods: sand casting, special casting (investment, solid mold, EPC, ladle drainage sand, etc.). It is also used for the production of shot peening, low expansion and high temperature resistant coated sand. 200/270 mesh is used for the production of EPC coating. Adding 10-35% can effectively improve the air permeability. It is suitable for the use of various casting binders. It has been used by many cast iron and non-ferrous metal casting manufacturers at home and abroad.
Fused Ceramic Sand Advantages
The surface of fused ceramic sand is very smooth. As long as the old sand is slightly rubbed, the bonding film on the sand surface can be removed. Therefore, fused ceramic sand has a strong regeneration ability. Relatively speaking, after the foundry uses fused ceramic sand, the dedicated fused ceramic sand supplier for ladle drainage can collect the old sand, and then it doesn't need too much cost, as long as the bonding part of the sand surface is removed. After screening, it can be recycled. In this way, fused ceramic sand can be used repeatedly, greatly reducing the use cost, which can't be replaced by other molding sand.
