Technical field

The present invention pays close attention to a kind of device for casting continuously, and it allows cast metallic products continuously, such as has the slab of square-section, and has the bar (being also known as " shaped blank ") in two " T " cross section.

Especially, the device for casting continuously allows to install cast crystallizer and plate type crystallizer.

Background technology

Device for casting continuously is known, and it comprises supporting construction or framework, and supporting construction or framework limit closed tube-like support body, or limit the main body supporting and hold mould, hereinafter referred to as die main body.

Die main body can allow to install cast or plate mold according to its specific structural allocation.

Cast mould allows to obtain the metal product with very simple and uniform cross section, such as there is bloom or the billet of circle or square sectional, or there is bloom or billet that more complicated cross section still has arrowhead.

Known cast mould comprises: the first tube element, and it, during use in outside, is called conveyer; And second tube element, it, during use in inside, is called crystallizer.

Usually the crystallizer be made up of copper or its alloy has through chamber, and the shape and size of through chamber are roughly similar to the shape and size of the metal product be cast.

Due to high processing temperature, the outer surface of crystallizer continues cooling by cooling liquid (normally water).

In order to this object, hollow space or multiple cooling duct are set between conveyer and crystallizer, passing through and transmitting for water.

Make cooling water be circulated to the second end from the first end of crystallizer, the end that the corresponding cast article of described first end leaves, the end of described the second end correspondence casting molten metal, obtains adverse currentcooling relative to product in practice.

The mould of such acquisition inserts in die main body, and die main body limits accommodation chamber together with mould.

Fluid between first accommodating chamber and the second accommodating chamber connects by being included in hollow space between conveyer and crystallizer or cooling duct is made.

Cooling water is introduced into the first water accommodating chamber, through hollow space or cooling duct, and leaves the second accommodating chamber to be discharged subsequently.

Therefore, the cooling effect of crystallizer is roughly consistent in the whole extension on the surface of cooled impact.Exactly due to distinguishing cooling effect can not be obtained on its wall, this cooling condition makes cast mould not be very suitable for uneven with the consistent cast article of shape, particularly those large-sized cast articles, the beam (being also called " shaped blank ") in such as two " T " cross section.

When having the product in large scale cross section, due to the operational pressure of cooling liquid and due to thermal and mechanical stress, the wall of tubular crystallizer experiences sizable distortion.

Be similar to tubular crystallizer, each plate of plate crystallizer is provided with the cooling duct of multiple circulation for cooling water.

Cooling duct can directly be made in the thickness of each plate.Also be well known that, make longitudinal fluting on the surfaces of the board, during use, plate outward facing sides, longitudinal fluting is closed by closing slab to limit cooling duct.

The position of cooling duct in plate is designed to the function of the distinguishing cooling condition of the inner surface of crystallizer.

In each plate, the inlet end portion of cooling duct and outlet end refer to single inlet collector and single outlet collector respectively.

Inlet collector and outlet collector are connected to the equipment for supplying and process cooling water successively.

By suitably changing the flow of water by inlet collector and outlet collector, the cooling effect in plate can be distinguished, therefore, it is possible to the cooling effect in each section of difference cast article.

The appearance that distinguishing cooling effect prevents the inner tensions destroying cast metallic products or the appearance of breaking.

Inlet collector and outlet collector comprise port to be introduced by water and to be discharged in the cooling duct that arranges in plate, and these ports are arranged in frame element, near being connected to each other for the aperture place entered.

Introducing and discharge port are connected to the equipment of supply and process water successively with suitable pipe.
