Description
Technical Field
The utility model relates to a steel ingot pouring technical field, concretely relates to a chassis for pouring of polydisc steel ingot.
Background
The steel ingot casting is a process of pouring molten steel into a steel containing barrel to be cast and solidified into a steel ingot. After the molten steel is smelted in a steel-making furnace, the molten steel can be processed only by casting into ingots or billets with certain shapes. The process of casting steel by using the casting mould is called as ingot casting or die casting for short; the technological process of casting by the continuous casting method is called continuous casting for short. The steel ingots are classified into three basic types of killed steel, boiling steel and semi-killed steel according to the difference of oxygen content in molten steel before casting.
The casting method comprises the following steps: the steel ingot casting adopts an upper casting method and a lower casting method. The upper cast steel ingot generally has a better internal structure, less inclusions and lower operation cost; the surface quality of the lower cast steel ingot is good, but inclusions in the steel are increased due to the passing of the middle casting pipe and the runner. The size of the ingot depends on many factors, such as the capacity of the steelmaking furnace, the cogging capacity of the blooming mill, the size of the steel and the characteristics of the steel grade. The ingots used for the production of bars and sections are generally square in section (called square ingots); the steel ingots from which the slabs are produced are generally rectangular in section (called slab ingots); the steel ingots for producing the forging and pressing materials have square, round and polygonal shapes.
When a die casting process is adopted for casting steel ingots, in the casting process, molten steel flows into a steel flowing hole from a middle pouring pipe through a cross gate on a chassis and then enters a cavity of a steel ingot mold, and the molten steel is cooled and solidified to form steel ingots. In the process of cooling and solidifying the steel ingot, the tail part of the steel ingot, the steel flowing hole and the residual molten steel in the horizontal pouring channel are cooled and solidified together, and the steel column at the bottom of the steel ingot and in the steel flowing hole is pulled apart by the traditional steel ingot through the solidification shrinkage at the tail part of the steel ingot. On one hand, residual molten steel exists in the cross gate, and the later use of the cross gate is influenced after the molten steel is solidified; on the other hand, with the increasing of the output, the common pouring chassis can not meet the production requirement, the number of chassis pouring holes needs to be further increased, the disc multi-ingot pouring is realized, and the production efficiency is improved.
