Novel casting furnace

Abstract

The invention relates to comprehensive development and utilization of a machine design, physical metallurgy and a casting furnace and belongs to casting system engineering. Aiming to reduce the unnecessary loss and improve the product quality of casting enterprises, the invention designs a novel durable casting furnace. A dynamic physicochemical numerical value of a whole process is finished by the control of a computer and the requirements of a product design are met. A cylindrical grid type finance liner framework is designed on the structure of a furnace body; temperature-resisting materials including high-smelting-point 2*20 circular iron, gold powder, quartz, sand and the like are poured on the finance liner framework to form a high-quality furnace liner; an electric furnace grate is in a coil shape and heats uniformly so as to conveniently raise and control a furnace temperature. Tapping liquid of the casting furnace is driven by a speed reducer and is finished by a linkage mechanism, so as to realize automatic control and safety. The quality of molten iron in the casting furnace is required to be detected for three times in each hour to detect various physicochemical indexes until the yield of the molten iron is up to more than 98%.

Description

technical field [0001] The invention relates to comprehensive development and utilization of mechanical design, metallurgy and casting furnace, and belongs to casting system engineering. Background technique [0002] Existing foundry furnaces are divided into large, medium and small tonnages, and some electric melting furnaces are also in use, but regardless of the furnace form and tonnage of large, medium and small foundry enterprises, most of their internal structures are boric acid, gold powder, quartz, sand, stone, etc. Cotton cloth, sodium hydroxide and other materials are made by compacting and vibrating. The common problem is that the quality of use is not durable, mainly manifested in the cracking of the furnace, and it has been repaired many times within a year, which cannot meet the needs of high-quality workpieces. The control of furnace temperature, metal decomposition density control, critical control, and chemical element control cannot be achieved. The design...
