Abstract
The invention provides a converter cone oxygen lance with surface coating, which belongs to the technical field of converter steel-making. The oxygen lance can prevent steel from being stuck or welded on the outer surface of a conical tube, consequently, a converter cone oxygen lance can carry out blowing under any conditions, the matters stuck on the conical tube can automatically come off, and thereby the sticking problem of the converter oxygen lance is thoroughly solved. The converter cone oxygen lance with the surface coating comprises the converter cone oxygen lance, and is characterized in that the surface coating is fixed on the outer surface of the conical tube of the converter cone oxygen lance; and the surface coating is one or more of copper, aluminium, magnesium, manganese, zirconium, calcium, zinc, chromium, nickel, silicon, boron and carbon or the oxides of copper, aluminium, magnesium, manganese, zirconium, calcium, zinc, chromium, nickel, silicon and boron.
Description
Technical field
The invention belongs to the converter steeling technology field, particularly relate to a kind of converter oxygen lance with conical that has top coat.
Background technology
Converter oxygen gun is when blowing, and the body of a gun often sticks slag, causes sticking rifle.At present, the dry slag on the oxygen rifle is mainly cleared up by manual work, and cleaning oxygen rifle dry slag is the hottest in the converter, the most tired, the most dangerous manual work always; In addition, cleaning oxygen rifle dry slag also can influence production.The sticking rifle of converter oxygen gun is a global difficult problem, and countries in the world all do not have well to solve.
For fear of the sticking rifle of converter oxygen gun, adopt the converter oxygen lance with conical usually.Dry slag majority on the converter oxygen gun is slag or slag mixture, adopts oxygen lance with conical, can solve the sticking rifle problem of converter oxygen gun.It is many that dry slag glues, because the weight of self, dry slag has just come off along the tapered tube of oxygen lance with conical.But, be to process if form the tapered tube of converter oxygen lance with conical with the weldless steel tube of steel, then with converter in molten steel bond easily or weld together.If what glue on the converter oxygen lance with conical is not slag or slag mixture, but has been stained with the steel or the steel of having burn-on on the tapered tube, then the agglutinating material just can not come off on the converter oxygen lance with conical, and oxygen lance with conical also need carry out the labor cleaning, influences the production of converter.
Summary of the invention
To the deficiency of easy steel bonding of existing converter oxygen lance with conical steel tapered tube or welding steel, the present invention provides a kind of converter oxygen lance with conical that has top coat.This oxygen rifle can be stopped steel bonding of tapered tube outside surface or welding steel, thereby guarantees that the converter oxygen lance with conical blows under any condition, and the dung on the tapered tube can both come off voluntarily, thereby has thoroughly solved the sticking rifle problem of converter oxygen gun.
To achieve these goals, the present invention adopts following technical scheme, and a kind of converter oxygen lance with conical that has top coat comprises the converter oxygen lance with conical, is characterized on the outside surface of the tapered tube of said converter oxygen lance with conical, being fixed with top coat;
Said top coat is one or more in the oxide compound of copper, aluminium, magnesium, manganese, zirconium, calcium, zinc, chromium, nickel, silicon, boron, carbon or copper, aluminium, magnesium, manganese, zirconium, calcium, zinc, chromium, nickel, silicon, boron.
The degree of depth that said top coat infiltrates into the top layer of tapered tube is 1～10mm.
The treated length of said top coat on the outside surface of tapered tube is 0.01～10m.
Fixed surface coating on the outside surface of said tapered tube at the converter oxygen lance with conical, it adopts in plating, plasma spraying, high temperature sintering infiltration, electric welding or oxygen welding built-up welding, the pressure of explosion moulding process one or both.
Beneficial effect of the present invention:
The converter oxygen lance with conical that has top coat of the present invention has been avoided converter oxygen lance with conical tapered tube and molten steel, slag or slag mixture bonding or has been welded together; The molten steel, slag or the slag mixture that stick on the oxygen lance with conical tapered tube can be come off voluntarily, thereby reached the target that oxygen lance with conical avoids gluing rifle.

Among the figure: 1-shower nozzle, 2-tapered tube, the 3-oxygen rifle body of a gun, 4-oxygen rifle gun breech, 5-top coat.
Embodiment
As shown in Figure 1, a kind of converter oxygen lance with conical that has top coat comprises the converter oxygen lance with conical, on the outside surface of the tapered tube 2 of said converter oxygen lance with conical, is fixed with top coat 5;
In the oxide compound that said top coat 5 is copper, aluminium, magnesium, manganese, zirconium, calcium, zinc, chromium, nickel, silicon, boron, carbon or copper, aluminium, magnesium, manganese, zirconium, calcium, zinc, chromium, nickel, silicon, boron one or more.
The degree of depth that said top coat 5 infiltrates into the top layer of tapered tube 2 is 1～10mm, and its treated length on the outside surface of tapered tube 2 is 0.01～10m.
Fixed surface coating 5 on the outside surface of said tapered tube 2 at the converter oxygen lance with conical, it adopts in plating, plasma spraying, high temperature sintering infiltration, electric welding or oxygen welding built-up welding, the pressure of explosion moulding process one or both.
Fixed surface coating 5 on the outside surface of said tapered tube 2 at the converter oxygen lance with conical, its concrete steps are following:
Step 1: the outside surface of converter oxygen lance with conical tapered tube 2 is polished, polishes, and clean out;
Step 2: one or both in employing plating, plasma spraying, high temperature sintering infiltration, electric welding or oxygen welding built-up welding, the pressure of explosion moulding process; With in the oxide compound of copper, aluminium, magnesium, manganese, zirconium, calcium, zinc, chromium, nickel, silicon, boron, carbon or copper, aluminium, magnesium, manganese, zirconium, calcium, zinc, chromium, nickel, silicon, boron one or more, be fixed on the outside surface of converter oxygen lance with conical tapered tube 2.
The present invention also alloy steel pipe of available taper replaces common steel tapered tube.
The outside surface of converter oxygen lance with conical tapered tube 2 is polished, polishes, and after cleaning out; Employing contains chromium more than 5%, nickeliferous nickel chromium triangle base welding rod more than 3%, carries out the electric welding built-up welding at tapered tube 2 outside surfaces, forms top coat 5; The degree of depth that said top coat 5 infiltrates into the top layer of tapered tube 2 is 4mm.Postwelding polishes, and adopts plasma spraying again, with zirconium oxide spray coating on outside surface.
