Different Kind Of Casting Method For Fused Cast Series Block

Made from high-purity, high-density, high-strength materials and MAS matrix-optimized system, shaped by pressing, prefabrication and vibration. With subtle formula design, unique technical process, they have, which identified up to the leading domestic level and received recognition and praise.

Refractoriness of refractory brick refers to the property that refractory’s multiphase reaches to a specific softening degree when at high temperature without any load, which shows the ability of resistance to high temperature. It is a basic scale to measure the ability of resistance to high temperature and basic technical index to show its high temperature property.

1. Normal casting: fused cast series block adopts normal riser casting and the riser is eliminated in hot state. The cut section is divided into two parts, the first part is

solidified which crystallized dense, and this part accounts for 40%-50% thickness of casting; another part is then solidified which has shrinkage and coarse crystallization. The price of fused cast block produced in this way is relatively low, and it is mainly use in upper structure and sidewall of the tank of glass furnace.

2. Tilt casting: Tilt casting is that makes the mold in a special angle before casting and then casts the mold by putting the riser in one side. This can get a dense area in the T section and can be used to get higher accuracy in the T direction, so fused cast block produced in this way can be mainly used in side wall of glass furnace.

3. Void free casting: The shrinkage hole is concentrated in a certain area, and removes the shrinkage with diamond saw after cooling. The remaining useful part is homogeneous and dense, and the average bulk density is close to the theoretical density. Fused cast block manufactured in this method is mainly applied to bottom of tank, channel, electronic refractory brick for sale and other high request parts in glass furnace, and the price is also relatively high.

After melting and refining the mixed material of fused cast series blocks in the electric arc furnace which needs to reach the casting standard, then pouring the molten liquid into the casting mold by the electric furnace, the operation process is called casting.
