Hot-dipping coating polymetallic compound horizontal continuous casting copper-clad steel device

Abstract

The invention discloses a hot-dipping coating polymetallic compound horizontal continuous casting copper-clad steel device with a good continuous casting effect, and the device comprises a pay-off rack, a descaling decorticator, a wiredrawing straightening machine, a polishing buffing machine, an ultrasonic cleaning device, a preheating furnace, a nitrogen protection device, a hot dipping nickel smelting furnace, a front ceramic film coating graphite crystallizer, a horizontal continuous casting furnace, a rear ceramic film coating graphite crystallizer, a circular cooling water tank, a guidance and traction device and a product forming device. The hot-dipping coating polymetallic compound horizontal continuous casting copper-clad steel device has the advantages that a copper-clad steel wire rod with large length can be produced, the thickness of a copper layer is convenient to control, a steel core wire is subjected to hot nickel dipping by virtue of a nitrogen protection device and a hot-dipping nickel smelting furnace; nickel is dipped before the steel core enters a copper liquid so as to ensure that the nickel-dipped copper core wire is dipped with copper; the copper liquid is free from the pollution of the steel core wire; and when the steel core wire enters the copper liquid, the purity of the copper can be relatively guaranteed, namely guaranteeing the electrical conductivity.

Description

technical field [0001] The invention relates to a horizontal continuous casting device, in particular to a hot-dip coating multi-metal composite horizontal continuous casting copper-clad steel device. Background technique [0002] The production methods of copper-clad steel currently include: electroplating method, welded pipe cladding method and casing cladding method. These methods are derived from the same type of process in different periods and different needs. Due to the different production processes, there are different disadvantages. The electroplating method is a copper plating process extended from electroplating zinc chromium and other processes. The conductor passes the current through the adsorption of anions and cations, and is completed in acid electrolysis. Due to the strength of the current, the thickness of the copper layer is generally relatively thin, and the acid electrolysis remains on the surface. Note, it is easy to cause secondary corrosion to form...

Problems solved by technology

The electroplating method is a copper plating process extended from electroplating zinc chromium and other processes. The conductor passes through the current and uses the adsorption of anions and cations, and is completed in acid electrolysis. Due to the strength of the current, the thickness of the copper layer is generally relatively thin, and the acid electrolysis remains on the surface. Note, it is easy to cause secondary corrosion to form holes, and the discharge of acid electrolysis in the electroplating process seriously pollutes the environment

The welded pipe cladding method and the sleeve cladding method use mechanical drawing shrinkage molding. This process has serious disadvantages and restrictions on the length and bonding degree of the product. The general length is only 6-9 meters, and the bonding interface is not in molecular form. Fusion, there is an interface containing air, easy to form an oxide layer, the product of this process is difficult to obtain satisfactory results in actual use
