Submerged arc furnace combination gripper bottom ring

Name: bottom ring, bottom ring body material: T2 Process: Casting Uses: This device is a combination of the gripper closed submerged arc furnace cooled integral bottom ring. The inside of the stainless steel annular plate (1), water-cooled protective sheath insulating plate ring plate (2), half torus (3), the contact element protection support ring plate (4), the separator (6) composed of; the inside of the annular plate (1 ) and stainless steel ring plate (2), the contact element protection support ring plate (4) with welding, torus (3) and then with the ring-plate (2) and the contact element protection support ring plate (4) Welding welding a monolithic the bottom of the cooling loop. The bottom of the ring only to avoid the often barbed fire leaking, replace regular shutdown problems and to meet the closed carbide furnace combination gripper work demands in production, can effectively improve the quality of the electrode column, greatly enhance its gripper The results, to fully meet the protective effect and its role in guiding the electrode column conductive means to avoid leakage in the course of the phenomenon, but also has a better economy. Can greatly improve its service life, a significant reduction in the number of shutdown due to reasons of the bottom ring. Combined with the bottom ring gripper submerged arc furnace, is a submerged arc furnace parts, including the body, the body of the waterway, the bottom of the waterway outlet pipe welded ring in communication with the bottom ring outlet pipe Unicom lead pipes, the outside bottom ring glows "concave" shape, basically solved the retaining screen due to high temperature insulation powder insulation bad times fire, leakage problems and avoid accidents, improve the operation rate and reduce consumption. A combination of gripping means gripping the composition and description combination electrode consists of upper and lower electrodes coat the electrode shell, contact elements, the bottom of the ring, protection screen, feeding tubes, hot and cold air device electrode, an electrode waterway, electrode pressure release device, accident tongs, lift vertical cylinders and other components. Coat the end face of the upper electrode assembly electrode pressure release device and accident clamp assembly side electrode cooling, hot air devices. Coat the lower electrode fixed electrode waterways, feeding tube, the lower end of the contact element hanging at the bottom of the ring and stainless steel protection screen and other equipment. Second, the bottom ring Material Description Material: copper bottom T2 T2 copper ring with the whole cast, because the high thermal conductivity of copper, so that greatly improved the efficiency of cooling water, recycled water and difficult to scale, can greatly improve the service life, reduce the bottom ring of reasons maintenance shutdown three times, the bottom of the copper ring scope applies to all large submerged arc furnace, such as: calcium carbide furnace, ferrosilicon furnace, nickel furnace calcium, manganese alloy furnace operating modular gripper, quality assurance, welcome Advisory negotiations. Combined gripper electrode technology developed by the Norwegian company Elkem, the nineties of the first in the calcium carbide furnace introduce the technology. Enterprises through the digestion and absorption of technology and continuous improvement, the advantages of modular gripper electrode technology is increasingly apparent in recent years in large and medium submerged arc furnace construction, expansion is widely used.
