Problems solved by technology
However, after the shutdown, the steering roller in the steering chamber will cool and shrink, and cannot provide sufficient tension to the strip. If the steering roller reaches a sufficient expansion temperature, it will take a long time to start the machine, which will have a great impact on production efficiency.

The invention discloses a furnace tail steering chamber for hot galvanizing band steel production. The furnace tail steering chamber for hot galvanizing band steel production comprises a steering chamber body and a steering roller, wherein a first heating mechanism and a second heating mechanism are fixed to two sides of the steering chamber body; heating areas of the first heating mechanism and the second heating mechanism are arranged facing the steering roller; and axes of the first heating mechanism and the second heating mechanism are parallel to an axis of the steering roller. The furnace tail steering chamber for hot galvanizing band steel production has the remarkable effects that two electric heating radiation pipes are arranged on opposite angles of the steering chamber body so as to heat the steering roller, so that the steering roller can be heated to be expanded and deformed within a short time so as to form convexity for producing a larger tensile force to band steel, theband steel is prevented from deviating, the starting-up time is greatly shortened, the production efficiency is effectively improved, and the starting-up cost is reduced.
Description
technical field [0001] The invention relates to the technical field of strip steel hot-dip galvanizing, in particular to a furnace tail turning chamber for hot-dip galvanized strip production. Background technique [0002] Hot-dip galvanizing, also known as hot-dip galvanizing, is a method in which steel components are immersed in molten zinc to obtain a metal coating. In recent years, with the rapid development of high-voltage power transmission, transportation, and communication, the protection requirements for steel components are getting higher and higher, and the demand for hot-dip galvanizing is also increasing. [0003] At present, the strip steel hot-dip galvanizing process is roughly divided into uncoiling, cleaning, annealing, cooling, hot-dip galvanizing, spraying, leveling, passivation, winding and other processes. In the above process, the annealed steel strip is required to be air-cooled and soaked to a certain temperature before entering the zinc pot for hot-...
