Abstract

The invention discloses a pretreatment mechanism for producing tantalum strips, and particularly relates to the technical field of tantalum strip processing. The pretreatment mechanism comprises a salt bath furnace body, a furnace cover is installed on the salt bath furnace body, two inclined holes are symmetrically formed in the furnace cover, two supporting tables are fixedly and symmetrically installed on the two sides of the upper end of the salt bath furnace body, an unwinding wheel base and a motor fixing base are fixedly installed on the two supporting tables respectively, an unwindingwheel is movably installed on the unwinding wheel base, a winding motor is fixedly installed on the motor fixing base, and a winding wheel is fixedly installed at the output end of the winding motor.The salt bath efficiency of the tantalum strips is improved, the oxidation effect of the surfaces of the tantalum strips is improved, and magnetic driving is adopted, so that the problems that a holeneeds to be formed in a salt bath furnace body during conventional motor driving, the heat preservation effect of a furnace body is affected, and even if the sealing effect is high, a sealing device is inevitable to be damaged are solved, and then the safety accident of solution exposure is avoided.

Description

technical field [0001] The invention relates to the technical field of processing tantalum bars, and more specifically, the invention relates to a pretreatment mechanism for producing tantalum bars. Background technique [0002] Capacitors are widely used in communications, computers, automobiles, home appliances, aerospace and other fields today. Tantalum electrolytic capacitors made of tantalum powder as anode and tantalum wire as anode lead have small size, large capacitance, high degree of chipping, It has the characteristics of good reliability, long service life and other excellent comprehensive performance, so it can work normally under the harsh conditions that many other capacitors such as ceramics and aluminum film capacitors cannot do. [0003] Tantalum is a steel-gray metal with a chemical symbol Ta. It has extremely high corrosion resistance. It does not react to hydrochloric acid, concentrated nitric acid and "aqua regia" no matter in cold or hot conditions. T...
