Abstract
The utility model relates to a sliding brick for controlling the flowing speed of the molten steel; the shape of the sliding brick for controlling the flowing speed of the molten steel is a rectangle with a lug boss; both ends of a bottom plate are in circular arc shape; both ends of the lug boss are also in the circular arc shape; the rectangle is provided with a through hole with a counter bore; the length a of the rectangle is 298 to 302mm, the width b is 208 to 212mm, and the thickness c is 42 to 46mm; the diameter d of the through hole is 28 to 32mm, and the distance e from the center line to the left end surface of the through hole is 118 to 122mm; the thickness f of the bottom plate of the rectangle is 19 to 21mm; and the radius of the circular arc of both ends (R1is equal to R2) is 103 to 107mm. The sliding brick for controlling the flowing speed of the molten steel has good thermal stability, strong anti-oxidation capability, and good molten steel and steel slag corrosion and erosion resistant capability, does not produce smoke and pollute the environment, and the use effect of the utility model up to four to five times.
Description
Technical field
The utility model belongs to a kind of refractory material, is specifically related to a kind of sliding plate brick of controlling molten steel flow speed.
Background technology
The sliding plate brick of control molten steel flow speed is the vitals that steel-making connects the equipment of annotating, and is the valve that the control molten steel draws off, and can accurately control many advantages such as molten steel flow speed, therefore, is widely adopted in the whole world.But the sliding plate brick of present domestic employing mainly is unburned and conventional aluminium carbonaceous sliding plate brick that burn till, the material that this series products uses is with sintered alumina, bauxite chamotte and electric smelting and fused mullite are main raw material, part is added carbon component and antioxidant in matrix, bond adopts phenolic resins, through mixing and molding, ≤ 200 ℃ of oven dry or under reducing atmosphere, burn till and form the carbon combined fire-resistant material, the slide plate of this material is organized little close, pore is fine, and the carbon residue that contains some, so molten steel and slag liquid are difficult to erosion, but resistance to impact is because the oxidation of carbon, cause short texture, reduced anti-erosion again.Its shape major part bottom is a rectangular slab, and the through-hole diameter of boss is 65mm, and reaming is too fast in the use like this, be generally service life once, because its volume is big, and Heavy Weight, consumable material is many in the steel-making.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of sliding plate brick of controlling molten steel flow speed, it is synthetic by aluminium, zirconium and carbon, this brick has Heat stability is good, the opposing molten steel that oxidation resistance is strong and good and the erosion and the scouring capability of slag, in use there is not smog, free from environmental pollution, its result of use reaches more than 4～5 times.
The technical solution of the utility model: a kind of sliding plate brick of controlling molten steel flow speed, its cuboid that is shaped as the band boss, the base plate two ends are circular arc, and the two ends of boss also are circular arc, and cuboid is provided with the through hole of band counterbore; The length a of cuboid is 298～302mm, and width b is 208～212mm, and thickness c is 42～46mm, through-hole diameter d is 28～32mm, the through hole center line is 118～122mm apart from the left side apart from e, and cuboid base plate thickness f is 19～21mm, and the radius R 1=R2 of two ends circular arc is 103～107mm.
The utility model compared with prior art has following beneficial effect: this brick has Heat stability is good, the opposing molten steel that oxidation resistance is strong and good and the erosion and the scouring capability of slag, in use do not have smog, free from environmental pollution, its result of use reaches more than 4～5 times.
Technical indicator is as follows:
Because reducing of its shape and through-hole diameter can make volume reduce, weight saving has reduced the consumption of steel-making material.
