Solid coal tar pitch is extruded into small rods and, for this reason, is often referred to as pencil pitch. In the aluminum industry, coal tar pitch is used as a binder in the manufacture of electrodes which primarily consist of petroleum or anthracite coal. As these electrodes are heated at high temperatures over a period of weeks, the ingredients in the electrodes are converted to C. For this reason, coal tar pitch is also often referred to as ‘C pitch’ or ‘binder pitch’. Coal-tar pitch is used in the manufacture of grate electrodes for steel arc furnaces. It is also used to impregnate and strengthen refractory brick (for lining industrial furnaces) and in surface coatings, such as pipe-coating enamels and black varnishes used as protective coatings for industrial steelwork and as antifouling paints for boats. It is also used as a component in the manufacture of activated C, and C refractory for blast furnace lining and tap-hole clays. Hard pitch is used as a binder for foundry cores. It is also used to produce pitch coke, which is used as the C component of electrodes, carbon brushes, and carbon and grate particles.Please feel free to us for more information.
