Abstract
The utility model discloses a steel casting middle package. The main body is an open vessel with a fluid outlet (2), the open vessel (2) is connected with a vacuum tank body (1) through a pipeline (3), the vacuum tank body (1) is equipped with a fluid intake tube (5) equipped for connecting the hot metal ladle, and the vacuum tank body (1) is equipped with a vacuum equipment (4). The steel and iron casting middle package of the utility model can respectively place the open vessel (2) and the vacuum tank body (1) to different places according to the location used, the pipeline (3) connected with the open vessel (2) and the vacuum tank body (1) can be randomly lengthened or shortened, therefore, the location can be flexibly utilized with no limitation; the open vessel (2) and the vacuum tank body (1) are two parts, therefore, the maintenance can be performed separately, simply and conveniently.
Description
Technical field
The utility model relates to a kind of iron and steel casting equipment, especially a kind of iron and steel cast tundish.
Background technology
At present, in China's steel smelting procedure, need enter strand equipment again with molten steel in the ladle through the tundish purified treatment.Publication number is that the Chinese patent of CN2600197 discloses a kind of cast tundish, its primary structure is that open containers is provided with top pressure closure, the high-temperature liquid metal molten steel flows into tundish main opening container in the ladle, vacuum equipment makes the header field on open containers top form vacuum, handles thereby molten metal is carried out vacuum purification.This tundish is because open containers and top cover are connected as a single entity, and volume is bigger, so use this tundish to be subjected to place limitation constraint; Moreover volume is too big, also is unfavorable for safeguarding.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned weak point, and a kind of place of applying in a flexible way is provided, and is beneficial to the iron and steel cast tundish of maintenance.
The utility model is achieved in that iron and steel cast tundish comprises the open containers that has liquid outlet, and this open containers connects vacuum tank by pipeline, and this vacuum tank is provided with for the feed tube that links to each other with ladle, and described vacuum tank is connected with vacuum equipment.
As a kind of improvement of the present utility model, described vacuum tank internal upper part is provided with screen pack.
As another kind of improvement the of the present utility model, described vacuum tank is divided into multi-segment structure, between each section for being tightly connected.
As another kind of improvement the of the present utility model, described vacuum tank is divided into expansion chamber and vacuum chamber two parts, and its expansion chamber communicates with vacuum chamber by aperture.
As another kind of improvement the of the present utility model, described vacuum tank top is provided with and adds the alloy material mouth.
As another kind of improvement the of the present utility model, the feed tube of described vacuum tank is provided with breather pipe.
During use, the vacuum tank of the utility model iron and steel cast tundish links to each other with ladle by feed tube, molten steel in the ladle enters vacuum tank by pipeline, gas in the molten metal and non-metallic inclusion float after through the vacuum tank vacuum, then, the molten steel that vacuum purification is handled enters open containers by pipeline, and molten steel flows out the steel billet of casting from the liquid outlet of open containers again.The utility model iron and steel cast tundish, different local according to using the place open containers and vacuum tank can be placed in, the pipeline that the two connected can prolong arbitrarily or shorten, the place so the utility model can be applied in a flexible way is not subjected to place size restriction; Because open containers and vacuum tank are two parts,, safeguard simple and convenient so can safeguard respectively when safeguarding.The vacuum tank internal upper part of the utility model iron and steel cast tundish is provided with screen pack, is beneficial to the gas and the dust that separate in the molten steel, the protection vacuum system.The utility model also is provided with expansion chamber at the vacuum tank internal upper part, is beneficial to collection and eliminating to gas in the molten steel and dust.For easy to maintenance, the utility model also is divided into multistage with vacuum tank, but each section be necessary for when connecting and be tightly connected, and is provided with manhole on vacuum tank, with convenient to safeguarding and change refractory material etc. in the tank body.The utility model also has on vacuum tank top and adds the alloy material mouth, so that molten steel is carried out alloying, improves yield of alloy.The feed tube of the utility model vacuum tank is provided with breather pipe, and gas enters in the vacuum tank together with molten steel, to increase degasifying effect.
Description of drawings
Fig. 1 is the utility model iron and steel cast tundish structure schematic diagram.
The specific embodiment
As shown in Figure 1, the utility model iron and steel cast tundish, its main body is the open containers 2 that has liquid outlet, open containers 2 connects vacuum tank 1 by pipeline 3, this vacuum tank 1 is connected with vacuum equipment 4, also be provided with feed tube 5 on the vacuum tank 1, feed tube 5 couples together ladle and vacuum tank 1, molten steel just enters from ladle and carries out alloying, the degassing, impurity elimination etc. in the vacuum tank 1 by this pipe 5, is equipped with valve on open containers 2 and the pipeline 3 that vacuum tank 1 is connected with on the feed tube 5 of vacuum tank 1.Vacuum tank 1 internal upper part of the utility model iron and steel cast tundish is provided with screen pack 13, the motion that is beneficial to gas and dust in the molten steel with separate.The utility model also is provided with expansion chamber 12 at vacuum tank 1 internal upper part, promptly vacuum tank 1 is divided into two chambers with refractory plate, less is expansion chamber 12, another is a vacuum chamber, this expansion chamber 12 communicates with vacuum chamber by aperture 11, gas enters expansion chamber 12 with the mixture that is mingled with by aperture 11 in the molten steel in the vacuum chamber, and falls to this 12 bottoms, chamber, and the bottom has the dedusting mouth.For install, carrying, easy to maintenance, the utility model also is divided into multistage with vacuum tank 1, as being divided into two sections or three sections, each section is connected to and is tightly connected; The utility model can also be established a plurality of manholes at vacuum tank 1, when to the maintenance of this section or when changing refractory material, can enter from the manhole of this section and gets final product.The utility model has on vacuum tank 1 top and adds the alloy material mouth, so that alloy material fully mixes with molten steel, improves billet quality and yield of alloy.The utility model is provided with breather pipe on the feed tube 5 of vacuum tank 1, to increase degasifying effect.The vacuum tank liner of the utility model iron and steel casting tundish is a refractory material, and the outside is a steel construction.
