Abstract
The utility model relates to a swing chute of a composite material. The swing chute comprises a shell, a lifting lug mounted on the outer side of the shell and a firebrick lining layer mounted on the inner side of the shell, wherein the firebrick lining layer is provided with a work lining layer; the thickness of the work lining layer is 200-300mm; the bottom surface on the inner side of the work lining layer is in an arc shape; an impact layer is arranged on the inner side of the work lining layer; the thickness of the impact layer is 150-250mm; the product is simple and convenient to construct and is quickly dried after pouring construction; quick roasting of the work lining of the swing chute can be realized, and the work lining can be quickly applied to tapping; once iron flux is 80,000-90,000 tons; the swing chute has the characteristics of good resistance against scrap iron scouring, good erosion resistance, good thermal shock resistance, reduction of comprehensive cost, remarkable increase of product benefits and the like; and the comprehensive benefits and once iron flux of the work lining of the swing chute can be effectively increased, and the service life can be effectively prolonged.
Description
Technical field
The utility model relates to technical field of refractory materials, is specifically related to a kind of oscillating chute of matrix material.
Background technology
The anti-material of blast furnace discharge yard oscillating chute working lining now generally adopts low cement deposit material, and low cement deposit material is because the aluminate cement add-on is more, and hydration time is longer, needs maintenance after the construction, and the construction period time lengthening can not rapid drying and baking; Described above material is shorter work-ing life, it is too frequent to cause the wobble groove working lining to repair, about 4 to 50,000 tons of general iron influxs, and the construction labor strength is big, the environment of high heat causes multiple unsafe factor again, and frequent maintenance repairs the oscillating chute working lining and quality more is difficult to guarantee; Along with the continuous progress of iron-smelting process, require also more and more higher work-ing life to the oscillating chute working lining with refractory materials; According to its damage mechanism in the anti-material use of oscillating chute working lining is thought: the working lining mould material not only will stand the erosion of high temperature sludge iron, the crackle of pour mass under the rapid heat cycle environment, bear the abrasion resistance of slag flowing molten iron, also must improve requirements such as the anti-material of working lining work-ing life.
Therefore, provide a kind of preparation method simple, installation is simple and efficient, and anti-slag iron performance of flushing is good, and erosion-resisting characteristics is good, and the oscillating chute of the matrix material of good thermal shock stability has market outlook widely.
Summary of the invention
At the deficiencies in the prior art, the utility model provides that a kind of preparation method is simple, installation is simple and efficient, anti-slag iron performance of flushing is good, erosion-resisting characteristics is good, the oscillating chute of the matrix material of good thermal shock stability.
The technical solution of the utility model is achieved in that a kind of oscillating chute of matrix material, comprise shell, be installed in the shell outside hanger, fire-brick lining inside the shell is installed, described fire-brick lining is provided with one deck work lining, the thickness of described work lining is 200 millimeters to 300 millimeters, the inside bottom surface of work lining is arc, be provided with silting deposit in work lining inboard, silting deposit thickness is 150 millimeters to 250 millimeters.
Described work lining cold crushing strength is 35 MPa to 42MPa, heat permanent line change %(1500 ℃ * 3H)+0.28-0.32, strength at normal temperature is 6.5 MPa to 7.3MPa, volume density 2.95 g/cm3 to 3.02g/cm3.
The utlity model has following positively effect: the utility model is simple in structure, easy to operate, fire-brick lining is provided with one deck work lining, the thickness of described work lining is 200 millimeters to 300 millimeters, the inside bottom surface of work lining is arc, be provided with silting deposit in work lining inboard, silting deposit thickness is 150 millimeters to 250 millimeters, the product easy construction, fast drying behind the casting and constructing can be realized oscillating chute working lining quick baking, drops into the use of tapping a blast furnace fast, an iron influx is at 8 to 90,000 tons, have good anti-slag iron performance of flushing, the good and good thermal shock stability of erosion-resisting characteristics, comprehensive cost reduces, characteristics such as the product benefit promotes greatly, comprehensive benefit and an iron influx requirement that can effectively improve and prolong the oscillating chute working lining.
