Graphite refractory products Refractory Materials Iron and steel smelting
Product introduction
Firebricks are called firebricks. Refractories are made of refractory clay or other refractories. Light yellow or brown. Mainly used for the construction of melting furnace, can withstand the high temperature of 1580℃- 1770℃. Also known as firebrick. Refractory material of certain shape and size. According to the preparation process, it can be divided into sintered brick, non-sintered brick, cast brick (cast brick) and refractory insulation brick; Can divide for standard brick, common brick, unusual brick by shape size. Can be used as high temperature building materials, construction kiln and various thermal equipment structure materials. It can withstand various physical and chemical changes and mechanical effects at high temperatures. Such as firebrick, clay brick, high aluminum brick, silicon brick, magnesia brick and so on.
Its properties
Carbon brick has good thermal stability, small coefficient of thermal expansion, high temperature resistance, resistance to the erosion of various acids, alkali, salt and organic solvents, but easy to oxidize in an oxidizing atmosphere.
Carbon brick is dark gray, shiny, burned into a good carbon brick does not stain the hand, with a small hammer knock clear sound. High refractoriness and load softening temperature, good thermal shock resistance; It is not wet by molten slag and molten iron, and almost not corroded by all acid, alkali, salt and organic drugs. It has good slag resistance, stable volume at high temperature, high mechanical strength, good wear resistance, and good electrical and thermal conductivity.
In addition, carbon is easy to oxidize, whether the raw material calcination or product roasting and the use of products, must be carried out in the reducing atmosphere.
Graphite refractory products
Graphite refractory products are made of natural graphite as raw material and clay as binder. This kind of product has graphite clay crucible, distillation tank, cast steel plug brick, nozzle brick and sheng steel barrel lining brick. The most widely used graphite clay crucible for steelmaking and smelting of nonferrous metals.
