Abstract
The invention discloses a combined protection brick for a side blowing gun and relates to a steel-making converter structure. The protection brick is formed by combining an upper brick body and a lower brick body which have a semi-sector shape. The upper surface and the lower surface of each of the upper brick body and the lower brick body are parallel; the front end faces of the upper brick body and the lower brick body are rectangular planes; the rear end faces of the upper and lower brick bodies have a curved surface shape corresponding to the corresponding positions of a furnace wall; both side surfaces of each of the upper brick body and the lower brick body are symmetrical planes; the lower surface of the upper brick body is provided with an inclined semicircular groove with a downward opening; the diameter of the semicircular groove is less than that of the side blowing gun; the space intersection angle of the axis line of the semicircular groove and the axis line of the furnace wall is equal to the space intersection angle of the set axis line of the side blowing gun and the axis line of the furnace wall; the upper surface of the lower brick body is provided with an inclined semicircular groove with a downward opening; the diameter of the semicircular groove is less than that of the side blowing gun; the space intersection angle of the axis line of the semicircular groove and the axis line of the furnace wall is equal to the space intersection angle of the set axis line of the side blowing gun and the axis line of the furnace wall; and after the upper brick body and the lower brick body are combined into one whole body, the outline shape of the whole body is the same as that of the integrated protection brick. The combined protection brick has the advantage that fire clay is tightly filled into a gap between the side blowing gun and the protection brick so as to avoid penetration of molten steel and prevent the accidents of gun burning and steel leakage.
Description
Technical field:
The present invention relates to the steel-making converter structure, particularly a kind of built-up type side-blown rifle protects brick.
Background technology:
In converter steelmaking, in order to strengthen the stirring in molten bath, improve the metallurgical reaction dynamic conditions, adopt the bottom blowing technology usually, in converter end rifle is installed and is blown into stirring gas.In order to protect end rifle and to prevent that molten steel from infiltrating the bottom furnace lining, need end rifle be installed in monobloc(k)type and protect in the brick, and fill end rifle and the slit protected between the brick full with refractory mortar.Because the medullary ray of end rifle protects the radially identical of brick with the end rifle of furnace bottom, adopt monobloc(k)type at the bottom of rifle protect brick, to end rifle with when protecting the slit filling refractory mortar between the brick; Easily the slit is filled completely and filled closely; Thereby prevented the molten steel infiltration, protected end rifle, avoided burning rifle and bleed-out accident.
In order further to strengthen the stirring in combined blown converter molten bath, particularly after the converter employing slag splashing technology, because furnace bottom rising, the end rifle stirring action of combined blown converter descends, and obtains good stirring in order to make converter molten pool, bottom side, top blow converter steel-smelting technology occurred.This steel-smelting technology is external except adopting end rifle to be blown into microgas, also on the converter molten pool sidewall, with certain side-blown angle (being defined as side-blown rifle medullary ray and converter molten pool sidewall furnace lining radial angle) the side-blown rifle is installed, and is blown into stirring gas to the molten bath.The side-blown rifle also need protect the brick protection, prevents that molten steel from infiltrating and taking place bleed-out and burning the rifle accident.
Existing monobloc(k)type is protected brick and is shaped as: the brick body is half fan piece shape, and upper and lower surfaces is parallel, and front end face is a rectangle plane, and aft end face is the curved surface shape corresponding to the furnace wall correspondence position, and two sides are the plane of symmetry, and two plane of symmetry space extending Plane intersects are axial line in the furnace wall.
Because there is the angle that blows side in the furnace lining of side-blown rifle medullary ray and converter molten pool furnace wall between radially; Protect brick if still adopt monobloc(k)type; Because side-blown rifle and the slit of protecting between the brick are little; Be difficult to refractory mortar the side-blown rifle and protect slit between the brick and fill full and fill closely, molten steel infiltrates easily, causes rifle and the bleed-out accident of burning.Therefore, need the new side-blown rifle of invention to protect brick and protect the side-blown rifle.
Summary of the invention:
The objective of the invention is to overcome above-mentioned defective, provide a kind of built-up type side-blown rifle to protect brick.
First scheme of the present invention is: protect brick and combined by the upper and lower brick body of partly fanning piece shape, the thickness of upper and lower brick body equals monobloc(k)type respectively and protects the half the of brick thickness; The upper and lower surfaces of upper and lower brick body is parallel; Front end face is a rectangle plane, and aft end face is the curved surface shape corresponding to the furnace wall correspondence position, and two sides are the plane of symmetry; Two plane of symmetry space extending Plane intersects are axial line in the furnace wall; Last brick body lower surface offers the tilting half slot that Open Side Down, and the half slot diameter is less than side-blown rifle diameter, and the side that the half slot axial line and axial line space, the furnace wall angle of cut equal to set is protected the rifle axial line and axial line space, the furnace wall angle of cut; Following brick body upper surface offers the tilting half slot that Open Side Down, and the half slot diameter is less than side-blown rifle diameter, and the side that the half slot axial line and axial line space, the furnace wall angle of cut equal to set is protected the rifle axial line and axial line space, the furnace wall angle of cut; Behind the upper and lower brick body zoarium, it is identical that gabarit shape and monobloc(k)type are protected the brick gabarit.
Alternative plan of the present invention is: protect brick and combined by left and right brick body; Protecting brick with monobloc(k)type is that the interface is split to form along the plane perpendicular to brick body upper and lower surfaces that the side of setting is protected rifle axial line place; Left side brick body right flank offers opening tilting half slot to the right; The half slot diameter is less than side-blown rifle diameter, and the side that the half slot axial line and axial line space, the furnace wall angle of cut equal to set is protected the rifle axial line and axial line space, the furnace wall angle of cut; Right brick body left surface offers opening tilting half slot left, and the half slot diameter is less than side-blown rifle diameter, and the side that the half slot axial line and axial line space, the furnace wall angle of cut equal to set is protected the rifle axial line and axial line space, the furnace wall angle of cut.
The invention has the advantages that: adopt built-up type side-blown rifle to protect brick, can guarantee that refractory mortar closely is filled into the side-blown rifle and protects in the slit between the brick, avoid molten steel to infiltrate, prevent to burn rifle and bleed-out accident.
