Abstract
The invention belongs to the technical field of fire-resistant tools, and particularly relates to an integral type mixing steel ladle tap hole prefabricated part. The integral type mixing steel ladle tap hole prefabricated part comprises an integrated body which is an arc-shaped concave part, an inner side opening is formed in one end of the arc-shaped concave part, an outer side opening is formed in the other end of the arc-shaped concave part, the arc-shaped concave part is gradually contracted from the inner side opening to the outer side opening, and hanging parts are fixed on two sides of the arc-shaped concave part. The integral type mixing steel ladle tap hole prefabricated part overcomes defects of site construction, and is scientific and reasonable in production process, a product produced through the integral type mixing steel ladle tap hole prefabricated part has higher compactness and higher strength than a product of the field construction, therefore, the service life of the product is greatly prolonged, and can be prolonged by more than two times, and labor intensity and fire-resistant cost are reduced.
Description
Technical field
The invention belongs to fire-resistant apparatus technical field, relate in particular to a kind of monoblock type and convert ladle tapping hole prefabricated component.
Background technology
Ladle is used for steel mill, Foundry Works accepts molten steel, carries out pouring practice before open hearth, electric furnace or converter.So general ladle all is to have one to go out the tapping hole that molten steel is used.Because present ladle tapping hole (mouth) degree of depth and width when design is all less, thereby the anti-material that makes the tapping hole place use often is subjected to various adverse effects when constructing at the scene, finally causes the anti-material intensity in construction back not high.Since can't bear washing away when frequently putting molten steel upside down, so the life-span is not long, for guaranteeing smelting work, be through repeatedly repairing.Cause the hidden danger of smelting and secure context.
Summary of the invention
The objective of the invention is to solve above-described technical problem, provide a kind of monoblock type to convert ladle tapping hole prefabricated component, its technical scheme is as follows:
A kind of monoblock type is converted ladle tapping hole prefabricated component, it is characterized in that, described monoblock type is converted ladle tapping hole prefabricated component and is comprised the integral type body, described integral type body is recessed of arc, the end that described arc is recessed is inboard mouthful, the other end that described arc is recessed is lateral port, recessed of described arc by inboard mouth laterally mouth shrink gradually, suspender member is fixedly arranged on the both sides that described arc is recessed.
Optimal way is that recessed of described arc waters material feeding by the high alumina spinel and injects the moulding of mould after vibration.
Optimal way is that described inboard mouth and lateral port are provided with outward extending transition inclined-plane.
Monoblock type provided by the invention is converted ladle tapping hole prefabricated component, when making, before being the ladle construction, according to the shape and size of converting ladle tapping hole (mouth), carry out mould in advance, and the high alumina spinel is watered material feeding requirement according to pre-manufactured product in mould carry out vibration moulding, maintenance, baking, produce required prefabricated refractory product, corresponding suspender member is installed when prefabricated, the position that installs to capable of hoisting during use, and fixing with pressure ring or steel plate welding.When in use, the inboard mouth of recessed of arc is placed on the inboard of ladle and since recessed of described arc by inboard mouth laterally mouth shrink gradually, so inboard mouthful bigger, can better draw molten steel.And the lateral port of recessed of arc is placed on the outside of ladle because lateral port is less, so that the speed that steel flow goes out speeds, the outflow of convenient molten steel.Fixedly there is suspender member both sides recessed of described arc.Can so that the installation of recessed of whole arc and shift more convenient, laborsaving.
Recessed of arc of the present invention waters material feeding by the high alumina spinel and injects the moulding of mould after vibration.Make product better strengthened aspect compactness and the intensity.
Inboard mouth of the present invention and lateral port are provided with outward extending transition inclined-plane.Molten steel can play good guiding function so that can enter in recessed of the arc better, more efficiently.
The present invention has overcome the limitation of site operation, and production technology is scientific and reasonable, and the product of producing will be higher than site operation aspect compactness and the intensity.So the life-span increases substantially; Can improve more than 2 times service life, reduced labour intensity and saved fire-resistant cost.

The specific embodiment
Specify embodiment below in conjunction with Fig. 1:
A kind of monoblock type is converted ladle tapping hole prefabricated component, it is characterized in that, described monoblock type is converted ladle tapping hole prefabricated component and is comprised integral type body 1, described integral type body 1 is recessed 1 of arc, the end that described arc is recessed 1 is inboard mouthful 2, the other end that described arc is recessed 1 is lateral port 3, and recessed 1 of described arc mouthfuls 3 shrinks laterally gradually by inboard mouthful 2, and suspender member 4 is fixedly arranged on the both sides that described arc is recessed 1.
Optimal way is that recessed of described arc waters material feeding by the high alumina spinel and injects the moulding of mould after vibration.
Optimal way is that described inboard mouth 2 and lateral port 3 are provided with outward extending transition inclined-plane 5.
Monoblock type provided by the invention is converted ladle tapping hole prefabricated component, when making, before being the ladle construction, according to the shape and size of converting ladle tapping hole (mouth), carry out mould in advance, and the high alumina spinel is watered material feeding requirement according to pre-manufactured product in mould carry out vibration moulding, maintenance, baking, produce required prefabricated refractory product, corresponding suspender member is installed when prefabricated, the position that installs to capable of hoisting during use, and fixing with pressure ring or steel plate welding.When in use, the inboard mouth of recessed of arc is placed on the inboard of ladle and since recessed of described arc by inboard mouth laterally mouth shrink gradually, so inboard mouthful bigger, can better draw molten steel.And the lateral port of recessed of arc is placed on the outside of ladle because lateral port is less, so that the speed that steel flow goes out speeds, the outflow of convenient molten steel.Fixedly there is suspender member both sides recessed of described arc.Can so that the installation of recessed of whole arc and shift more convenient, laborsaving.
