  • Zircon Sand for Casting Ceramics Refractory Material Factory

    Zircon Sand for Casting Ceramics Refractory Material Factory

    Zircon sand (zircon) is extremely resistant to high temperatures, and its melting point reaches 2750 degrees Celsius. And resistant to acid corrosion. 80% of the world’s production is directly used in the foundry industry, ceramics, glass industry and the manufacture of refractory materials. A small amount used in ferroalloy, medicine, paint, leather, abrasives, chemical and nuclear industries. Very small amounts are used for smelting zirconium metal.

    Zircon sand containing ZrO265 ~ 66% is directly used as the casting material of iron metal in the foundry because of its melting resistance (melting point above 2500℃). Zircon sand has lower thermal expansion, higher thermal conductivity, and has stronger chemical stability than other common refractory materials, so high-quality zircon and other adhesives together have good adhesion and are used in the casting industry. Zircon sand is also used as bricks for glass kilns. Zircon sand and zircon powder have other uses when mixed with other refractory materials.

  • Copper Slag Grit Sand Blasting Abrasive for Surface Cleaning

    Copper Slag Grit Sand Blasting Abrasive for Surface Cleaning

    Copper ore, also known as copper slag sand or copper furnace sand, is the slag produced after copper ore is smelted and extracted, also known as molten slag. The slag is processed by crushing and screening according to different uses and needs, and the specifications are expressed by the mesh number or the size of the particles. Copper ore has high hardness, shape with diamond, low content of chloride ions, little dust during sandblasting, no environmental pollution, improve the working conditions of sandblasting workers, rust removal effect is better than other rust removal sand, because it can be reused, economic benefits are also very considerable, 10 years, the repair plant, shipyard and large steel structure projects are using copper ore as rust removal.

    When quick and effective spray painting is needed, copper slag is the ideal choice. Depending on the grade, it produces heavy to moderate etching and leaves the surface coated with primer and paint. Copper slag is a consumable silica free substitute for quartz sand.

  • High quality steel slag 60-80Mesh for good rust removal effect

    High quality steel slag 60-80Mesh for good rust removal effect

    Iron and steel slag can be divided into blast furnace slag and steelmaking slag. On the first hand, the former one is produced by the melting and reduction of the iron ore in the blast furnace. On the other hand, the latter one is formed during the steelmaking process by changing the composition of iron.
