Abstract

The utility model provides a simple high -efficient miniature wire rod electric heat plates equipment especially utilizes the equipment of power direct heating work piece and coated metal. Its purpose is such realization: in treating that the plate wire material inserts two electrically conductive crucibles, adding the coated metal in the crucible, let in inert gas on the crucible, the high power current power supply of the low pressure circular telegram on two crucibles makes the coated metal melt and makes two wire rods part heating between the crucible simultaneously, the coated metal is hot dip to the part of wire rod between two crucibles under heating effect, moves the wire rod and make the whole hot dips of wire rod accomplish, close the power at last, close inert gas, take the wire rod out. The utility model discloses utilize electric current direct heating wire rod, very big increase the thermal efficiency of power, spraying inert gas by the spray tube is direct on molten metal and wire rod, having avoided the oxidation of molten metal, this improves coating quality and has the great role practicing thrift the coated metal.

Description

Miniature wire electric heating coating apparatus

(1) technical field

This utility model patent is related to hot-dip coating apparatus, the equipment for particularly carrying out hot dip process to metal wire rod.

(2) background technology

Hot dip is the workpiece that cleaning treatment is crossed is put in the coated metal pond dissolved etc. by oil removing, pickling, leaching medicine, drying Take out after temperature, surface of the work can wrap the thick coated metal of comparison, typically up to more than 0.2mm.

Plating is that pipe fitting is put in the solution that composition is zinc salt after oil removing, pickling using electrolysis installation, and is connected The negative pole of electrolysis installation, on the opposite of pipe fitting photo zincography is placed, and the positive pole for being connected to electrolysis installation switches on power, using electric current from just Pole to the displacement of negative pole will deposit one layer of zinc on pipe fitting.

Plated item coating is relatively thin, it is impossible to keep plating piece to avoid corrosion for a long time.For metal antirust treatment typically now Processed using hot dip.Hot plating technology needs are heated to fusing point temperatures above coated metal makes metal molten.

The hot-dip coating apparatus melting pan opened upper end of wire rod, bottom lock.Wire rod have top enter melting pan in Jing line balls deflector roll again Return on liquid level.This equipment has oxide and impurity is liable to stick to coating surface, and deflector roll is easily generated with coated metal The deficiencies such as Fe alloy slag.For improving equipment that a kind of this Patent No. ZL03284402.6 " hot-dip coating apparatus of metal wire rod " is proposed For：It is made up of melting pan, hot dip combination die, wire rod preheating and equipment water jetting cooler, there are the duct flowed out for plating solution, group in melting pan side Matched moulds has the upper and lower mould with the mould tire for flowing sideways into hole and with vertical centre bore stifled and core rod composition, and mould tire is fixed with melting pan UNICOM, upper and lower mould blocks up the other end for being mounted vertically in mould tire, the porous core rod of a middle clamping permeable plating solution.Preheating and water Device for cooling is respectively provided with the upper and lower with combination die.

Above equipment has following deficiency：1. structure or more complicated, it is impossible to be miniaturized.2. wire rod preheating is by sensing Coil, heating relies on heating.The thermal efficiency of induction coil is very low, and heating heats position away from wire rod, molten metal Heat is transmitted to wire rod and necessarily leads to amount of heat loss.3. coated metal liquation necessarily leads to a large amount of oxidations with air contact Slag.

Not enough for more than, this utility model directly heats wire rod, significantly increases the thermal efficiency of power supply using electric current； Noble gases are directly sprayed on molten metal by jet pipe, it is to avoid the oxidation of molten metal, this is improved to saving coated metal Quality of coating has great role.

(3) utility model content

The purpose of this utility model patent is just to provide a kind of simple efficient mini wire rod electric heating coating apparatus, in particular with The equipment that power supply directly heats workpiece and coated metal.

What the purpose of this utility model patent was realized in：The equipment has wire rod, conductive crucible 1, conductive crucible 2, electricity Source, coated metal, noble gases jet pipe；Characterized in that, having in the middle of conductive crucible 1, conductive crucible 2, wire rod can be passed through Hole, and holes is coaxial, two noble gases jet pipes directly on conductive crucible 1 and conductive crucible 2, its noble gas for spraying Protective coating metal and wire rod are not oxidized, and thermal source is that power supply acts on generation in wire rod and coated metal.Treating plated wire In being inserted into two conductive crucibles, coated metal is added in crucible, noble gases are passed through on crucible, it is low on two crucibles Pressure high current power supply is powered makes coated metal melt while heating the wire segment between two crucibles；Coated metal is in heat work With part of the lower hot dip to wire rod between two crucibles, moving wire rod completes wire rod whole hot dip；Power supply is finally closed, is closed Noble gases are closed, wire rod is extracted out.
