Abstract
The present invention relates to a spraying apparatus for spraying cooling water onto a workpiece, the spraying tool being located along at least one of upper and lower sides of a workpiece to be transferred along a width direction of the workpiece; And shut-off portions that cover the spray portion at the end portions of the spray portion and block the cooling water sprayed from the spray portion by moving along the spray portion. The material cooling apparatus as described above cools the material in accordance with the width of the material and reduces the temperature variation in the width direction of the material, thereby improving the quality of the material upon cooling.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material cooling apparatus, and more particularly, to a material cooling apparatus for cooling a material by spraying cooling water in accordance with the width of the material.
The material produced by the continuous casting process, such as a slab, is heated in a heating furnace, and is produced as a product having a predetermined thickness through a rolling process such as a roughing and finishing mill. At this time, the material is heated to the target temperature according to the steel species in the heating furnace. Further, in the case of a material which is first rolled to a predetermined thickness through a rough rolling mill, acceleration is considered for grain refinement or control of a transformed structure.
Generally, the accelerated cooling is performed by the headers positioned above and below the conveyed material. The headers have a plurality of nozzles. The cooling water is supplied to the headers through the pump and the supply pipe, and is injected through the nozzles. The injected cooling water contacts the conveyed material to realize cooling of the material.
On the other hand, when the material is actually cooled, the cooling water is injected through the entire header, and the operation of the header is controlled according to the thickness, feed rate, or the component of the material, and the cooling water is injected through only a part of the header.
However, materials having various widths are applied, and the material is transported along the width direction. As a result, it becomes difficult to control the temperature along the width direction of the work, and flatness or deformation of the work may be caused.
The present invention provides a material cooling apparatus capable of cooling a material in accordance with the width of the material.
Another object of the present invention is to provide a material cooling apparatus capable of reducing the temperature variation in the width direction of a material to improve the quality of the material upon cooling.
The present invention provides an image forming apparatus comprising: an upper spray portion positioned above a material to be transferred along a width direction of the material and spraying cooling water on an upper side of the material; A lower spraying part located below the material to be transferred along the width direction of the material and spraying cooling water below the material; Blocking portions that are located at both ends of the upper injection portion and cover both end portions of the upper injection portion and block the cooling water which is moved along the upper injection portion and injected from the upper injection portion; Guide portions extending downward from the blocking portion toward the workpiece, respectively, and being moved by the blocking portion; And auxiliary blocking portions located parallel to each other and spaced apart from the blocking portion and connected to the guide portion and positioned adjacent to the upper side of the lower jetting portion, wherein the auxiliary blocking portions are upwardly injected from the lower jetting portion And the cooling water is shut off.
The cooling water injected from the upper jetting portion may flow into the guide portions and be guided to the workpiece along the guide portions.
The guide portion includes a main guide portion formed in a plate shape and extending from the blocking portion toward the workpiece; And auxiliary guide portions extending from both sides of the main guide portion and positioned in parallel with each other so that the cooling water injected from the upper jetting portion passes between the auxiliary guide portions.
The blocking portion includes a slide portion formed with an insertion space portion for inserting the end portion of the upper injection portion and covering at least a part of the upper injection portion and moving along the upper injection portion to change an area covered by the upper injection portion; And a slide driving unit connected to the slide unit to move the slide unit along the upper injection unit.
Wherein the slide driving unit includes: a guide bar passing through the slide unit and connected to the upper ejecting unit; A driving body connected to the slide portion to move the slide portion along the guide bar; And a connecting bar connecting the guide bar and the driving body.
Wherein the upper jet portion includes: a head portion positioned along the width direction of the workpiece and supplied with and storing cooling water; And nozzle portions formed in the head portion to face the transported material.
