Abstract
The utility model provides an anti-oxidation layer, which is composed of a wood charcoal layer (2) and a graphite layer (3), wherein the bottom layer is the wood charcoal layer (2) and one layer of the graphite layer (3) is paved on the wood charcoal layer (2). In a copper product production line frequency furnace for production, a copper liquid anti-oxidation layer disclosed by the utility model is adopted, so that the problem that copper in the line frequency furnace is oxidized when the production of copper products is at a heat-preservation and material-waiting phase; through the practices and operations, the anti-oxidation effect of liquid copper in the furnace is obvious: the oxidized degree of the copper in the furnace is effectively controlled when the production is recovered again and a phenomenon that the copper liquid is oxidized nearly does not happen; with the adoption of the method disclosed by the utility model, the product rejection rate is changed from the previous 100% into 2-3%; and therefore, the finished product rate is improved, the energy consumption is reduced and the production period is shortened.
Description
Technical field
The utility model relates to the anti oxidation layer that is used to protect metal, is specifically related to be used for the anti oxidation layer of copper liquid protection.
Background technology
Existing high-quality oxygen-free copper rod blank all adopts up-drawing method production; Up-drawing method is the method that a kind of need melt cathode copper, cast continuously; Comprise that specifically cathode copper is fused into copper water, is distracted into steps such as copper bar base, roll forming through draw-gear in main frequency furnace; Can produce and obtain oxygen content below 30ppm, length can reach the copper bar blank of endless.
Because raw material cathode copper price fluctuation in recent years is big; Make aggravation of contradictions between the sale of supply of raw material and product; Like this in order to reduce business risk; Often occur interimly stopping production, copper water occurs and in main frequency furnace, be incubated situation to be expected, but during insulation is waited to expect, be easy to cause the oxidation of copper in the stove, the copper in the back main frequency furnace that resumes production is almost completely oxidized, give next time that production causes very big influence.
The utility model content
The purpose of the utility model is to provide a kind of anti oxidation layer, and this oxide layer is invested in the stove between copper material main frequency furnace soak, makes to have improved subsequent steps such as copper liquid is intact, can directly be used for drawing, rolling lumber recovery, reduced energy resource consumption.
The purpose of the utility model realizes through following technical measures:
A kind of anti oxidation layer is characterized in that: be made up of charcoal layer and graphite linings; Bottom is a charcoal layer, on said charcoal layer, is provided with graphite linings.
Above-mentioned anti oxidation layer is in the protection that is used for copper liquid, thereby in order further to make copper liquid be in reducing environment raising antioxidant effect, the thickness of above-mentioned charcoal layer is good between 120mm～150mm.
In order to make the further isolated outside air of copper liquid, further improve antioxidant effect, the thickness of above-mentioned graphite linings is good between 80mm～100mm.
Preferably, above-mentioned charcoal is the calcination charcoal of particle diameter at 1～10mm, and this charcoal layer thickness is 120mm～130mm; Above-mentioned graphite preferably adopts commercially pure 3299 graphite phosphorus sheets, and this graphite linings thickness is 90mm; They are the commercially available prod.
More preferably, above-mentioned charcoal is through calcining, and after screening, gravity preparation and magnetic separation, do not contain the charcoal of metal impurities such as iron filings.
Specifically, a kind of anti oxidation layer is characterized in that: be made up of charcoal layer and graphite linings; Bottom is that thickness is 120mm～130mm, the particle diameter calcination charcoal layer at 1～10mm, and being equipped with thickness on the said charcoal layer is technical pure 3299 graphite linings of 90mm.
The utility model beneficial effect is following:
Produce employing the utility model anti oxidation layer in the main frequency furnace at copper material to be produced; Drawing copper material production on having solved is in insulation and waits to expect the oxidized problem of copper in the stage main frequency furnace; Through practice, the oxidation-protective effect of liquid copper is remarkable in the stove: the oxidized degree of copper has obtained effective control in the stove when resuming production once more, the oxidized phenomenon of copper liquid almost do not occur; Product rejection rate by original 100% to adopting 2～3% behind the utility model; Improve lumber recovery, reduced energy resource consumption, shortened the production cycle.
