Foundry chromite ore sand AFS40-45 is suitable for train axlebox casting production.Train axlebox casting is an important component of the train axle, with built-in journals and other components. The railway axlebox also needs to withstand loads and has the function of storing axle oil. The axle box bearing housing and axle box should be tightly fitted to prevent oil leakage, dust, and rainwater from entering. The axlebox is usually made of cast iron or cast steel material, with high strength and complex structure.

Chromite sand AFS25-30 gets a particle range of 0.4-0.8mm. It always works for lost foam casting process for Casting steel and Casting Iron such as mechanical parts. There are several advantages of casting chromite sand AFS25-30:

Casting chromite sand AFS45-50 AFS40-45 are mostly used for steel casting and iron casting. The consumption quantity is large. Recently we delivered 1000 tons for the customer in North Asia.

Chromite sand AFS 40-45 is a quick chilling material with high refractory temperature and excellent thermal conductivity. Therefore, in the casting of cast iron, it is necessary to prevent cold iron from being replenished outside the casting to prevent expansion and deformation of the cast iron after pouring.

Chromite sand AFS40-45(40-70mesh)is a commonly used foundry sand for the resin No-bake process. Resin no-bake sand is generally a casting molding method for foundry. In this procsss, the furan resin is added to the original sand for mixing. And then the molding sand can self-harden without heating or adding air. This casting process does not require high equipment requirements, has high casting accuracy, and is widely used. However, the resin No-bake process has high requirements for the original sand. Especially for the recycling and reuse of casting sand. It requires high requirements for the hardness, strength, particle size, acid consumption value, etc. of the original sand.

Chromite ore sand AFS 55-60 is a high-quality casting sand for shell molding. This sand generally refers to the high thermal strength, long heat resistance time, and small deformation at high temperatures. It can take a tough task that silica sand can’t do.
