Black Solid Fireproofing Material Using For High Temp Furnace Ball Shape Pitch

pherical asphalt is a kind of high temperature coal tar, which is made from coal tar pitch by heating, dissolving, spraying and cooling forming process. Asphalt is divided into two categories, namely, coal tar pitch and petroleum asphalt. The bituminous binders used in refractories are mainly coal tar pitch. The test material of asphalt adding heating asphalt dissolving dissolving kettle, electric heating coil power supply connected at the same time, the asphalt is ejected from the nozzle, into small particles from air atomization, asphalt particles in the cooling tower with natural air cooling into semi-finished products, by the cooling tower bottom into the three dimension vibration screening filter classification, which was consistent with the spherical asphalt produc

 

Spherical Asphalt Features

Spherical Asphalt has the characteristics of fixed carbon, toluene insoluble, high resin content, low ash, softening point 110, coking value 58%, ash 0.3%, volatile 57%, carbon 45%. Spherical asphalt products: high temperature asphalt, high temperature and ultra high temperature (spherical asphalt, asphalt softening point > 180 degrees), modified asphalt, asphalt and other series of soft coal tar products used in the production of ferrous material, ramming material, mending material, stemming, and MgO-C brick and other refractory materials.
