Abstract
The utility model discloses liquid steel casting equipment comprising an ingot mold; the upper part of the ingot mold is provided with an insulating cap; the ingot mold is arranged on an ingot mold chassis; a steel flowing channel is arranged in the ingot mold chassis and is communicated with a middle filling pipe arranged at one side of an ingot mold body; the steel flowing channel is communicated with a casting port at the bottom of the ingot mold; and the at least one casting port is arranged at the central position of the bottom of the ingot mold. In the liquid steel casting equipment, the slag rolling phenomenon in the casting process of liguid steel can be improved by changing the position and the quantity of the casting port of the ingot mold or deviating from the center of the bottom of the ingot mold or adding a plurality of casting ports; after the liquid steel casting process or the casting is finished, the flow field distribution and the temperature field distribution of the steel liquid in the ingot mold are changed, the defects such as center segregation and looseness of steel ingot are relieved, and simultaneously the segregation position of the steel ingot also can be changed to lead the segregation to deviate from the center but close to the rolling surface of the steel ingot.
Description
Technical field
The utility model belongs to smelt uses the production equipment technical field, is specifically related to a kind of liquid molten steel casting equipment.
Background technology
Along with development and national economy; Nuclear power with steel, boiler and pressure vessel with steel, wind power flange steel; Structural steel such as bridge, skyscraper requires increasingly stringent to the steel plate internal soundness, adopts technology such as forging, electroslag remelting and directional solidification to produce such steel plate mostly for guaranteeing the steel plate internal soundness, but owing to its production cycle is long; Manufacturing expense is high, and restriction enterprise further dwindles production cost.And the steel ingot that adopts conventional ingot mould production to pour into a mould, the sprue gate is in the center of ingot mould, according to metallurgical transmission principle knowledge; The steel stream relative temperature that is in the sprue gate vertical direction is high; Then cause steel ingot inside to have serious segregation and center porosity easily, steel ingot centre macrosegregation is eliminated in the subsequent handling and is alleviated with loose being difficult in, therefore rolling steel plate especially >=super-thick steel plate of 200mm; Inside often exists microdefect, causes flaw detection not conform to easily.
The utility model content
The purpose of the utility model is to provide a kind of can improve segregation of steel ingot inside center and loose liquid molten steel casting equipment; Adopt the utility model patent equipment and pouring procedure, but industrial mass manufacture goes out to meet more than the 200mm other steel plate of forge piece non-destructive testing standard JB/T5000.15-2007 F2 level.
A kind of liquid molten steel casting equipment; Comprise ingot mould, said ingot mould top is provided with hot top, and said ingot mould is arranged on the ingot mould chassis; Said ingot mould is provided with ladle canal in the chassis; Said ladle canal is communicated with the feed trumpet that is arranged on ingot mould one side, and the sprue gate of said ladle canal and ingot mould bottom is communicated with, and said have at least a sprue gate to be arranged on to deviate from the ingot mould bottom centre position.
Position, said sprue gate is arranged on the ingot mould bight.
Position, said sprue gate is arranged on ingot mould limit portion.
Said ingot mould bottom departs from ingot mould bottom centre, near on two adjacent side positions of ingot mould one or more sprue gates being set all.
Said ingot mould bottom departs from ingot mould bottom centre, near on two relative side positions of ingot mould one or more sprue gates being set all.
The utility model passes through to change the position and the quantity of ingot mould bottom pouring mouth, or departs from ingot mould bottom centre, or increases a plurality of sprue gates; Can improve after pouring molten steel process or cast finish, the flow field of the inner molten steel of ingot mould not only can alleviate the volume slag phenomenon of molten steel at casting process; After the high-temperature molten steel that pours from the bottom cast gate simultaneously gets into ingot mould, can improve the field distribution of steel ingot temperature inside, make in certain setting time of molten steel after casting process to notes are finished owing to the influence of original steel circulation road; On the cross section near cast gate above the molten steel temperature at position be higher than the molten steel temperature at other position; And be positioned at the sprue gate of bight or limit portion, since nearer apart from the ingot mould outer wall, cooling fast easily; Thereby can reduce the molten steel temperature of top, sprue gate, and then can influence the process of setting of whole steel ingot.Moving of position, sprue gate changed the position of segregation to a certain extent, makes segregation deviate from the center near surface of steel ingot, helps under the effect of the power of depressing greatly of the operation of rolling or follow-up heat treatment process makes segregation obtain fragmentation and improvement.Provide the foundation for producing the special heavy plate of protecting flaw detection and guaranteed cost, this equipment making is simple simultaneously, and the method operation is prone to row, has satisfied the demand of industrialized production.
