Abstract
The utility model discloses a tyre rotary spraying and cooling device for continuous casting and rolling of steel, comprising a casting wheel and a cooling steel belt, wherein the cooling steel belt covers a lower half circle of the casting wheel; a blank groove filled with liquid steel is arranged at the center of an outer circle of the casting wheel; an arc-shaped outer cooling device is arranged around the outer side of the cooling steel belt; an arc-shaped inner cooling device is arranged at the inner side of the casting wheel; and two side wall cooling devices are arranged on two side faces of the casting wheel. According to the tyre rotary spraying and cooling device for the continuous casting and rolling of the steel, the casting production efficiency is greatly improved and the energy consumption is reduced by more than 30%; with the adoption of a rotary indirect cooling way of the steel belt, the surface of the steel has no cracks and fewer oxidized skins, so that the quality and the precision of a finished product are improved, and the economic benefit is better.
Description
Technical field
The utility model relates to a kind of steel continuous casting and rolling cooling device, particularly a kind of wheel band rotary spray cooling device that is used for the steel continuous casting and rolling.
?
Background technology
At present, existing wire rod rolling technology is to use the continuous casting billet of bringing from steel mill, and the steel billet that comes out from steel mill also only is semi-finished product, after must going to be rolled to steel rolling mill, just can become the product of qualifying.At first be to get into heating furnace, be heated to 1050～1080 ℃ after, pass through then after the blooming mill repeat-rolling, get into finishing mill.The processing of steel rolling ownership stress metal, on hot rolling line, strip plate heating deliquescing is sent into milling train by roller-way, rolls into the size of customer requirements at last.
Wherein the process for cooling of steel embryo is a critical process wherein, guarantee that molten steel is even, the quality of the cooling of balance ability steel embryo, avoids occurring defectives such as face checking, center porosity, segregation.
Cooling means at present commonly used be free air cooling but, water-cooled but, the air water spraying type of cooling, the conventional type of cooling is difficult in and guarantees that steel billet cooling quality control shortens cool time again simultaneously.
The utility model content
Not enough in order to overcome existing steel continuous casting and rolling cooling device, the utility model provides a kind of wheel band rotary spray cooling device that is used for the steel continuous casting and rolling.
The utility model solves the technical scheme that its technical problem adopted: the wheel band rotary spray cooling device that is used for the steel continuous casting and rolling; Comprise casting wheel, cooling steel band; The cooling steel band wraps the lower branch of casting wheel, and center, casting wheel outer ring is provided with the embryo groove of perfusion molten steel; Be provided with the external cooler of arc around the cooling steel band outside, the inboard of casting wheel is provided with the interior device for cooling of arc, and the two sides of casting wheel are provided with two sidewall cooling devices.
The utility model has adopted unique wheel band rotation cooling to make the molten steel crystallization, and the steel speed of production increases substantially, and operation links up, energy loss is few; Through water spray cooling steel band, through steel band rotation carrying out heat exchange.
The beneficial effect of the utility model is, comes in from inside and outside and two sides in several roads of cooling moisture, and the cooling steel ingot is comparatively even, and every road water yield is adjustable at any time, and cooling effectiveness is high; Two side cooling points are arranged again, eliminated molten steel and put defectives such as bubble cracking, center porosity, segregation.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
The wheel band rotary spray cooling device that is used for the steel continuous casting and rolling comprises casting wheel 1, cooling steel band 2, and cooling steel band 2 wraps the lower branch of casting wheel 1, and center, casting wheel 1 outer ring is provided with the embryo groove 3 of perfusion molten steel; Be provided with the external cooler 4 of arc around cooling steel band 2 outsides, the inboard of casting wheel 1 is provided with the interior device for cooling 5 of arc, and the two sides of casting wheel 1 are provided with two sidewall cooling devices 6.
Interior device for cooling 5 is provided with 36～52 nozzles 7 that are equally spaced along cooling steel band 2 centers.
The overall diameter of casting wheel 1 is 3280～4980mm.
During casting, casting wheel 1 is divided into several cooling sections, and each cooling section is the arc length of module, in this length, adopts and the different water use model of relevant adjacent cooling section, and in fact the cooling arm is divided into section, and every section is supplied water separately.Cool off at casting wheel 1 four sides; Every section cooling water can be adjusted intake pressure and compressed air separately; 7 sections some places of nozzle endways; Casting wheel 1 is directly controlled through water control valve with the temperature of cooling steel band 2, can open, closes or reduce gradually, and cooling all is to accomplish through being adjusted in each nozzle 7 that ingot casting breaks away near each the cooling arm alone the casting wheel 1.The flow control valve of the nozzle 7 of device for cooling 5, external cooler 4 and sidewall cooling device 6 all is provided with meter accurately in being used for.Realize accurately control cooling water and compressed-air actuated flow through the valve of cooling arm.
The utility model has adopted unique wheel band rotation cooling to make the molten steel crystallization, and the steel speed of production increases substantially, and operation links up, energy loss is few; Through water spray cooling steel band, through steel band rotation carrying out heat exchange.Come in from inside and outside and two sides in several roads of cooling moisture, the cooling steel ingot is comparatively even, and every road water yield is adjustable at any time, and cooling effectiveness is high; Two side cooling points are arranged again, eliminated molten steel and put defectives such as bubble cracking, center porosity, segregation.
