Technological method and device for hot delivery and hot charging of continuous casting billet

Abstract

The invention discloses a technological method and a device for hot delivery and hot charging of continuous casting billets. According to the technological method, the continuous casting billets produced by a continuous casting machine are conveyed onto a hot delivery roller bed for hot delivery; when the continuous casting billets are conveyed to heating furnaces in a hot delivery manner, roller bed transverse-moving trolleys capable of performing reciprocating motion transversely are parked at the position of a hot delivery line along a track in advance; when the continuous casting billets are conveyed to the roller bed transverse-moving trolleys, the roller bed transverse-moving trolleys raise the continuous casting billets through platform lifting mechanisms to the height, corresponding to the heating furnaces, of a furnace feeding roller bed; and when the roller bed transverse-moving trolleys move transversely, the continuous casting billets are conveyed to the furnace feeding roller bed, and then delivered to the corresponding heating furnaces. The technological method has the advantages that through the roller bed transverse-moving trolleys equipped with the platform lifting mechanisms, hot delivery of the continuous casting billets in a plurality of steel rolling lines can be achieved; accordingly, not only can the hot delivery height of the continuous casting billets be adjusted to meet the requirements for the heights of different steel rolling furnace feeding roller beds, but also the quantity of the continuous casting billets can be determined according to the quantity of steel billets pushed by the heating furnaces at a time; and the device is simple in structure, flexible in delivery process, and efficient.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a device for conveying continuous casting hot slabs to a steel rolling heating furnace. Background technique [0002] With the development and maturity of continuous casting technology, the continuous casting billet hot delivery and hot charging technology, which makes full use of the continuous casting billet's own heat energy, has become one of the important means of energy saving and consumption reduction in steel production enterprises. Since the continuous casting slab hot delivery and hot charging process turns steelmaking-steel rolling into a closely linked integrated production system, it can not only greatly reduce energy consumption, increase metal yield, shorten product production cycle, but also improve product quality , and can reduce the floor area of ​​the plant and save investment. Therefore, this technology has shown great advantages in saving investment, redu...

Problems solved by technology

[0003] However, due to objective reasons such as the limitations of the process layout and the fact that a single continuous casting unit corresponds to multiple steel rolling production lines, the existing hot-feeding and hot-charging lines cannot be elevated according to the required roller table height, and the elevation is not accurate, and the hot-feeding position is not accurate.
