From the perspective of grey iron casting manufacturers, the characteristics of the product itself cannot be ignored. The following is an introduction to the basic features of gray iron casting.
First of all, the product is high in clay content and has low moisture content. In the process of sand preparation, we should pay attention to the content of mud and clay. The higher the content of the clay, the higher the strength of the clay will be.
In general, we should control the effective bentonite content between 7 and 10 percent. The amount of clay and effective clay in the sand should remain at the same level as the amount of mud.
Secondly, the water content of gray iron castings should be paid attention to whether they are purchased or produced. Water is one of the important factors that determine product adhesion and plasticity. If the water content is high, it will also cause the change in the cohesive force of the clay, leading to the decrease of the fluidity of the molding sand. Moreover, too low moisture will result in increased brittleness and some defects.
