P-D Refractories CZ a.s. P-D Refractories CZ a.s. is one of the biggest producers and suppliers of refractory products and raw materials. We produce and supply complete or partial linings of the thermal aggregates, especially for coke ovens, blast furnaces (including hot blast stoves), glass furnaces, electrolyzers for the primary production of
10.1.2.1 Steelmaking Refractories The electric furnace requires a variety of refractory products. Most important are the refractories in direct contact with the steel. Today's electric furnaces and EBTs generally use magnesite or magnesite carbon products in the steel contact zones.
Magnesite refractory bricks are mainly used in steel-making alkaline open hearth furnace, electric furnace bottom and furnace wall, converter permanent layer, metal mixer working layer, non-ferrous metal smelting furnace, high temperature tunnel kiln, cement rotary kiln lining, glass furnace regenerative chamber checker brick etc. Specification:
Refractory Brick for sale, an excellent kiln refractory material, is briefly called fire brick that has certain shapes and sizes. Refractory brick includes different types of burnt brick, unburned brick, fused cast brick and refractory insulating brick according to different manufacturing processes.
High Alumina Fire Bricks can be used in many kinds of industrial furnaces or kilns, such as blast furnace, hot blast furnace electric furnace for steel making and molten steel ladle as the furnace top and wall. High alumina bricks also can be used for checkerwork of regenerative chamber, reverberatory furnace and rotary kiln.
These electric furnace are available with a combination insulation of refractory bricks in the corners and low heat storage or either a robust insulation of light refractory bricks, quickly cooling fibre material . with a wide variety of optional equipment, these models can be optimally adapted to your processes.so the electric furnace have
Corundum brick is a refractory product with the content of alumina more than 90% and the principle crystalline phase is corundum, which have the characteristics of high cold compressive strength (up to 340MPa), high load softening start temperature (more than 1700 degrees C). good chemical stability, strong resistance to acid or basic slag, metal and glass liquid.
Dr. Dmitri Kopeliovich Electric Arc Furnace (EAF) is a steel making furnace, in which steel scrap is heated and melted by heat of electric arcs striking between the furnace electrodes and the metal bath. Two kinds of electric current may be used in Electric Arc Furnaces: direct (DC) and alternating (AC).
All tests were conducted in a conventional electric arc steelmaking furnace (Lectromelt Corp, model ST) lined with a basic refractory brick and covered with a rammed-alumina roof. The inside diameter of the furnace was 39 in, and it had a nominal capacity of 1 st of molten metal.
The steel making process involves several stages of thermal and chemical treatment requiring a variety of refractory linings that are compatible with many application conditions. The steel making process represents the metallurgical sector involving the pig iron transformation into steel, its transport and refining until the molding stage.
