Description

Supporting tray of steel mould for anode plate casting

Technical Field

The utility model belongs to the technical field of the tray, specifically a supporting tray of steel mould is used in anode plate casting.

Background

In the copper pyrometallurgical process, the copper anode plate casting mold is very important casting process equipment, and the casting process equipment is directly related to the quality and the casting cost of anode copper.

At present, the domestic and foreign copper anode plate casting mould mainly uses three materials of a cast iron mould, a cast steel mould and a copper mould. (1) The cast iron mold has low thermal conductivity and chilling and heat shock resistance, is easy to crack and even integrally fracture after being forcibly cooled after being cast by high-temperature molten copper, has short service life, poor safety and corrosion resistance, and Fe in the cast iron mold when the casting temperature is overhigh₃C will react with residual Cu in the copper liquid₂The cast wall is corroded by O, the porosity of anode copper is increased by CO released from the cast wall, and the cast iron mold is not high in cost but high in use cost and is gradually withdrawn from the market at presentA field; (2) the cast steel die has better shock resistance, is not easy to deform, has better thermal stability than a copper die, and the cast anode plate has regular physical appearance and good drapability. But the heat conductivity is poorer than that of a copper mold, so that the burning loss and the cracking of a casting washing area of a casting mold cavity are easily caused by insufficient temperature reduction in the casting process; (3) the copper mold has good thermal conductivity, does not react with copper liquid in the casting process, can be automatically cast by a female mold by a user, is simple and convenient to manufacture, can be used for remelting and remelting a waste mold in time, and the like, and large copper smelting enterprises can produce copper anode plates by using the self-casting copper mold under the condition of not considering fund occupation; however, when the copper mould is used, the casting scour area of the copper mould is easy to adhere to high-temperature copper water to cause mould sticking, so that a large amount of release agent is required to be sprayed on the surface of a copper mould cavity to prevent the mould sticking during casting. The price of the release agent serving as a chemical raw material rises again in recent years, so that the production cost is increased continuously, the release agent is attached to the surface of an anode plate and is easy to cause adverse effects on electrolysis and subsequent processes, the quality and the cost of enterprise terminal products are further influenced, and the release agent can cause mucous membrane due to uneven spraying or poor proportioning to form waste plates. Meanwhile, the copper mold is easy to deform and crack after being used for a long time, so that the plate surface thickness of the anode plate is uneven and the back ribs are increasedIs not good enoughThereby greatly reducing the quality of the anode plate and increasing the electrolytic production quality and the cost control difficulty of the next procedure.

Along with the comprehensive cost performance advantage of the steel die is continuously accepted and recognized, more and more enterprises adopt the steel die to cast the anode plate, but the heat conductivity of the steel die is poorer than that of the copper die, so how to improve the heat conductivity of the steel die is a problem which needs to be solved urgently.
