Abstract

The invention relates to alloy coating paste for manufacturing a steel back pure copper lining composite conductive tile. The alloy coating paste mainly comprises, by mass percentage, 38-42% of Mn, 18-22% of Ni, 35-40% of Cu and 2-3% of dehydrated borax. The materials are mixed, anhydrous alcohol and phenolic resin are added to the mixture to make the paste coasted on the surface of a back body of the composite conductive tile, the heat of molten metal fuses the coating layer into a layer 2-3mm in thickness after casting pouring, and the layer is composited with poured metal through metallurgical bonding. The alloy coating paste has the advantages that the back body is made of stainless heat-resistant steel or heat-resistant cast iron, the molten pure copper generated by thermit reaction is used as the material of a lining, the two materials are composited through metallurgical bonding, the back body is high in heat intensity, heat-impact-resistant and gas-corrosion-resistant, the lining is high in conductivity, and the composite body of the two can give ideal working features to workpieces, and low cost is achieved.

Description

Be coated with cream for the alloy of making steel backing fine copper lining electric conducting compound tile

Technical field

The present invention relates to the technology of processing for the Conducting copper tile of mineral hot furnace, particularly a kind of for making the alloy painting cream of steel backing fine copper lining electric conducting compound tile.

Background technology

Current mineral hot furnace method is the main method of producing ferroalloy, and the main expendable part-Conducting copper tile of mineral hot furnace electrode used therein holder is the vital part (seeing Figure of description Fig. 1) of this equipment, directly affects its service life and produces life originally.

Traditional Conductive holding element is to form with H96 brass casting, because its entirety is to do by copper, the consumption of copper is large, cost is high, and H96 copper has 4% foreign material (being mainly deoxidation residue and other element of adding for improving casting character), and large with respect to fine copper (T99) resistance, electric conductivity reduces by 20～30%, and that another shortcoming is the elevated temperature strength of copper is low, because this workpiece operating ambient temperature is high, its in being on active service often because of ablation, crackle, fall piece and lost efficacy, service life is limited.

Summary of the invention

Object of the present invention is just to provide a kind of using steel, iron as back of the body body, using fine copper liquid that thermit reaction was produced as lining material, the complex that bi-material metallurgical binding is formed, back of the body body material is stainless refractory steel or heat-resisting cast iron, calorific intensity is high, and heat shock resistance and gasproof body burn into lining body material are fine copper, and electric conductivity is strong, the two gives workpiece desirable operating characteristic with metallurgical binding complex, and the low alloy for making steel backing fine copper lining electric conducting compound tile of cost is coated with cream.

Solution of the present invention is such:

Be coated with a cream for the alloy of making steel backing fine copper lining electric conducting compound tile, described alloy is coated with cream mainly to be mixed by mass percentage by containing following raw material: Mn:38-42, and Ni:18-22, Cu:35-40, after dewatering borax: 2-3 cast; Add absolute alcohol and phenolic resins furnishing paste to be coated on the back of the body surface of electric conducting compound tile said mixture, after casting-up, the heat of molten metal is combined into composite bed with the metal metallurgy smelting of cast after coat is fused into 2～3mm thickness.

Advantage of the present invention is using steel, iron as back of the body body, using fine copper liquid that thermit reaction was produced as lining material, the complex under apocarpy, bi-material metallurgical binding being formed, back of the body body material is stainless refractory steel or heat-resisting cast iron, calorific intensity is high, and heat shock resistance and gasproof body burn into lining body material are fine copper, and electric conductivity is strong, the two gives workpiece desirable operating characteristic with metallurgical binding complex, and cost is low.

Brief description of the drawings

Fig. 1 is the back of the body body structure schematic diagram of electric conducting compound tile.

Fig. 2 is the top view of Fig. 1.

In figure, the 1st, back of the body body, the 2nd, compound lining.

Detailed description of the invention

The back of the body system of electric conducting compound tile of the present invention do be by workpiece figure paper size deduct will be compound liner thickness be shaped with being cast as method, as shown in Figure 2, different from conventional cast method is in the time making back of the body body casting mold, applies by the designed alloy powder of technical solution of the present invention and is coated with cream at the ad-hoc location of type wall.

Painting paste composition proportioning of the present invention is as follows:

Element term	Mn	Ni	Cu	Dewatering borax
					Mass percent	38-42	18-22	35-40	2-3
Granularity order <	200	200	200	200
					Purity	Electrolysis	99.5	Electrolysis	Technical grade

This alloy powder is coated in the surface of back of the body body with absolute alcohol and phenolic resins furnishing paste, as shown in Figure 2, coat is after casting-up, the heat of molten metal fuses into coat the composite bed of being combined with the metal metallurgy smelting of cast after 2～3mm thickness, and this composite bed is direct and fine copper backing layer metallurgical binding in the production technology of implementing subsequently.

Following table is embodiments of the invention:

?	Mn	Ni	Cu	Dewatering borax	Absolute alcohol and phenolic resins
						Embodiment 1	40	22	35	3	In right amount
Embodiment 2	38	22	38	2	In right amount
						Embodiment 3	40	20	37.5	2.5	In right amount
Embodiment 4	40	18	40	2	In right amount
						Embodiment 5	42	18	37	3	In right amount
