A process production method in which several ingot heating furnaces are parallel to the hot rolling direction at the same time

Abstract

The invention provides a process production method with multiple cast ingot heating furnaces simultaneously parallel to a hot rolling direction. A heating straddle is positioned between a cast ingot storage straddle and a hot rolling straddle; a track is communicated with a position beside a hot roll passage of the hot rolling straddle from the longitudinal direction of the cast ingot storage straddle, and the central line of the track is vertical to that of the hot roll passage; the operation direction of the hot roll passage is the hot rolling direction; a material storage table is arranged on the left side of the track of the cast ingot storage straddle; a plurality of rectangular box type furnace bodies are arrayed at equal intervals along the longitudinal direction of the heating straddle; the rectangular box type furnace bodies are positioned on the left side of the track; a trolley arranged on each rectangular box type furnace body can be in parallel docking with a composite skip car; as for one cast ingot, only a first-day vehicle and a second-day vehicle are needed for hoisting once, the loading time is shortened, the discharging speed is improved, rolling of a hot mill is greatly facilitated by continuous production, the hot rolling production efficiency is improved, and generated effects are apparent to common technicists in the art. The process production method has great significance in modern management of aluminum plate strip hot rolling workshops.

Description

technical field [0001] The invention belongs to the technical field of process production in aluminum strip hot rolling workshops, in particular to a process production method in which several ingot heating furnaces are simultaneously parallel to the hot rolling direction. Background technique [0002] The hot-rolling workshop is a production workshop that provides hot-rolled slabs and coils in the production of aluminum strips. The process flow of the hot-rolling workshop is roughly ingot casting→face milling→heating→hot rolling. The ingot heating furnace is the main equipment for this process. The ingot heating furnace is composed of a rectangular box-type furnace body and a trolley. The trolley is responsible for charging and discharging. The ingot heating furnace is characterized by a small furnace load and flexible production. It is mostly used for small batches and small-sized ingots. heating. [0003] Ingot heating furnaces are generally equipped with multiple sets a...

AI Technical Summary

Problems solved by technology

[0006]1. During the charging process, at least the cranes for the raw material span and the hot-rolled span need to lift the ingot once, and the charging time is relatively long;

[0007]2. The arrangement direction of the ingots on the trolley is perpendicular to the rolling direction of the hot rolling mill, so the crane needs to rotate the ingots by 90 degrees before putting them out. On the roller table of the hot rolling mill, due to the high heating temperature of the ingot, the rotation operation is extremely inconvenient;

[0008]3. The moving position of the trolley is limited by the roller table of the hot rolling mill, and cannot be completely moved out of the limit lifting position of the hot rolling span crane. In addition, the weight of the ingot must be within Within the hoisting range of the crane, the hoisting of lengthened or extra-heavy ingots is restricted
