Magmalox Fused Cast Blocks High Density and Erosion Resistant for Waste Incinerator Lining

Description of Magmalox Fused Cast Blocks

Magmalox Fused Cast Blocks is made of high-quality bauxite and imported Australian zircon sand, melted at high temperature in an electric arc furnace, and cast. Its compact structure has the advantages of wear resistance, impact resistance, high temperature resistance, and good thermal shock resistance. It is mainly used in parts that need wear resistance and high temperature resistance, such as slide rail blocks of metallurgical push-steel heating furnaces or tapping platforms (Outlet trough) The tapping platform of the walking-type heating furnace and the lining of the garbage incinerator.

Producing pcessing of FMagmalox Fused Zircon Mullite Block

1. Sand mold making:

The sand mold is made of silica sand and water glass as a binding agent. After the water glass and silica sand are mixed evenly in a mixer, a support box is installed according to the model requirements to start making the sand mold, and then it is loaded on the kiln car and pushed into the drying kiln for drying.

2. Raw material processing and proportioning by computer:

Raw materials such as alumina powder, zircon sand and desiliconized zirconium and other raw materials shall be put into storage for use or sent to raw materials for pretreatment after acceptance. After processing in the raw material workshop, the raw materials are proportioned for use in accordance with different product requirements.

3. Melting process:

Mainly in accordance with the requirements of the production plan, the matched fused zirconium corundum raw materials are added to the automatically controlled electric arc furnace and melted under the best conditions. If the temperature is low, a highly uniform melt cannot be obtained. It is easy to make the casting form a porous body, causing pores and cracks in the molten casting product, and the shrinkage will increase accordingly. The key to the melting process is to maintain a stable melting temperature system to obtain a melt with uniform chemical composition, low carbon content, a certain temperature and good casting properties. The melting process adopts a programmable computer program for automatic melting process control, so that the melting is sufficient and uniform.

4. Casting process:

Pour the molten material into a specially designed product mold. The fused cast electric fusion brick with compact structure and good performance is made. When casting with a suitably overheated melt, the shrinkage cavity of the zirconia corundum bricks is concentrated, the thickness of the dense zone increases, and the density of the entire product also increases. However, when the degree of overheating is too high, although the melt density increases, it is easy to cause cracks and large shrinkage holes in the product.

5. Heat preservation and annealing process:

The cast bricks are slowly cooled, so that the crystals of the prepared fused zirconia corundum bricks grow and form the best structure. Usually, an incubator filled with diatomaceous earth and other thermal insulation materials is used for annealing with molds, or an adjustable temperature resistance furnace or tunnel kiln is used for annealing with molds or demoulding according to a certain temperature system. The initial annealing temperature and holding conditions have a significant effect on the annealing effect.

6. Demoulding process:

The annealed fused cast zirconium corundum bricks are taken out of the cavity using equipment for product inspection.

7. Machining rocessing:

Check the appearance defects, brick size and surface accuracy of the bricks one by one, and carry out high-precision grinding according to the requirements of users to ensure the size and surface accuracy of the bricks.

8. Pre-assembling and packing:

After Machining processing, it is pre-assembled to ensure that the product size is packaged and shipped.
