Abstract
The utility model relates to a blast-furnace tapping channel with impact area liners. The blast-furnace tapping channel comprises a tapping channel shell, a tapping channel working liner arranged in the shell and a tapping channel arranged on the tapping channel working liner, wherein a tapping channel bottom liner is arranged at the bottom of the tapping channel, two impact area liners are arranged vertically at two sides of the tapping channel, the height of each impact area liner is 1/2 of the height of the tapping channel, the vertical section of each impact area liner is arc-shaped, and the cross section of each impact area liner is also arc-shaped, and the thickness of each impact area liner is 25cm to 50cm; when in use, the impact area liners are under even stress, and the impact area liners are reasonable in structure, high in pressure-resisting capacity, high in corrosion resistance and scientific and reasonable in thickness, therefore the service life of the tapping channel is prolonged and the general tapping amount of the tapping channel is enhanced.
Description
Technical field
The utility model relates to technical field of refractory materials, is specifically related to a kind of blast furnace iron outlet groove with the impact zone lining.
Background technology
Occur in the use procedure of blast furnace iron outlet groove working lining that the damage position is mainly at the molten iron impact zone, for ensureing the normal operation of tapping a blast furnace safely of blast furnace iron outlet groove, need to carry out work lining cover is watered to repairing, repairing is carried out after having gone out iron, at first iron and slag remaining in casting house are cleaned out, casting house work lining after repairing, whole service life extends, and the consumption of ton iron reduces.These materials are shorter because of work-ing life; In the use procedure of tapping a blast furnace, molten iron washes away and can be penetrated into gradually wherein, and after acquiring a certain degree, repair material can be peeled off by washing away of molten iron integral body, and patching material work-ing life is short, and to cause the casting house working lining to repair too frequent.The reparation construction labor strength is large, and the environment of high heat causes again multiple unsafe factor, and frequent maintenance is repaired the casting house working lining and caused quality more to be difficult to guarantee.Traditional work liner structure arranges and has irrational place, and work-ing life is short, affects the casting house working efficiency.
Therefore, provide a kind of simple in structure, installation is simple and efficient, and scour resistance is good, and erosion-resisting characteristics is good, and the blast furnace iron outlet groove with the impact zone lining of combination reasonably optimizing, have market outlook widely.
Summary of the invention
For the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, and installation is simple and efficient, and scour resistance is good, and erosion-resisting characteristics is good, the blast furnace iron outlet groove with the impact zone lining of combination reasonably optimizing.
The technical solution of the utility model is achieved in that a kind of blast furnace iron outlet groove with the impact zone lining, comprise the casting house shell, casting house working lining in the enclosure is set, be opened in the casting house on the casting house working lining, described casting house bottom is provided with casting house ditch bottom lining layer, be vertically arranged with two impact zone linings in the casting house both sides, the height of impact zone lining is 1/2nd of casting house height, the vertical tangent plane of impact zone lining be shaped as arc, the shape of the horizontal tangent plane of impact zone lining is also arc, the thickness of impact zone lining is 25 centimetres to 50 centimetres.
The upper surface of described impact zone lining is concordant with the upper surface of casting house working lining, and the width of impact zone lining upper surface equals the width of casting house working lining upper surface.
Between the bottom surface of described casting house shell and casting house working lining, fire-brick lining is set.
The utlity model has following positively effect: the utility model is simple in structure, easy to operate, comprise the casting house shell, casting house working lining in the enclosure is set, be opened in the casting house on the casting house working lining, described casting house bottom is provided with casting house ditch bottom lining layer, be vertically arranged with two impact zone linings in the casting house both sides, the height of impact zone lining is 1/2nd of casting house height, the vertical tangent plane of impact zone lining be shaped as arc, the shape of the horizontal tangent plane of impact zone lining is also arc, the thickness of impact zone lining is 25 centimetres to 50 centimetres, in use, the impact zone lining is stressed evenly, rational in infrastructure, anti-pressure ability is strong, corrosion resistance is strong, thickness is scientific and reasonable, work-ing life and the comprehensive iron influx of casting house have been improved.
The accompanying drawing explanation
Fig. 1 is the utility model plan structure schematic diagram.
Fig. 2 is the vertical tangent plane structural representation of the utility model.
Fig. 3 is the horizontal tangent plane structural representation of the utility model.
Embodiment
As Fig. 1, 2, shown in 3, a kind of blast furnace iron outlet groove with the impact zone lining, comprise casting house shell 1, be arranged on the casting house working lining 3 in shell 1, be opened in the casting house 5 on casting house working lining 3, described casting house 5 bottoms are provided with casting house ditch bottom lining layer 6, be vertically arranged with two impact zone linings 2 in casting house 5 both sides, the height of impact zone lining 2 is 1/2nd of casting house 5 height, impact zone lining 2 vertical tangent planes be shaped as arc, the shape of impact zone lining 2 horizontal tangent planes is also arc, the thickness of impact zone lining 2 is 25 centimetres to 50 centimetres.
The upper surface of described impact zone lining 2 is concordant with the upper surface of casting house working lining 3, and the width of impact zone lining 2 upper surfaces equals the width of casting house working lining 3 upper surfaces.Between the bottom surface of described casting house shell 1 and casting house working lining 3, fire-brick lining 4 is set.
The utility model only has casting house working lining 3 by original, change improvement and increased impact zone lining 2 at casting house work lining innermost layer, can realize the on-the-spot Quick pouring repairing of impact zone lining 2 and come into operation, casting house working lining 3 and impact zone lining 2 materials form through reasonably optimizing, the preparation method is easy, high and the comprehensive cost of product strength reduces, substantially improved the resistance to fouling of casting house working lining impact zone lining to the high temperature sludge flowing molten iron, scour resistance, antistripping, thermal shock resistance, the characteristics such as explosion-proof excellent property, can increase substantially and extend casting house working lining 3 and 2 work-ing lifes of impact zone lining, comprehensive iron influx is more than 200,000 tons.Impact zone lining 2 material selection compact aluminas are major ingredient, optimize and form a certain amount of electrofused mullite, and the high quality carbon SiClx, alumina powder and carbonaceous matrix material, high-strength compound wedding agent and detonation suppressor, through strict proportioning process, mixing evenly rear package encapsulation.Transport to behind the casting house scene after adding gauge water and stirring can realize the rapid construction cast after and come into operation, greatly shorten the construction maintenance time and, the height of this product impact zone lining 2 is 1/2nd of casting house 5 height, impact zone lining 2 vertical tangent planes be shaped as arc, the shape of impact zone lining 2 horizontal tangent planes is also arc, the thickness of impact zone lining 2 is 25 centimetres to 50 centimetres, rational in infrastructure, thickness forms through measuring and calculating, not only effectively extended the life-span of casting house, and old this locality, sound construction is stable, special shape design pressure resistance, work-ing life and the comprehensive iron influx of casting house have been improved.There is good society and economic benefit.
