Continuous casting billet conveying device and method

Abstract

The invention discloses a continuous casting billet conveying device and method, and belongs to the technical field of metallurgy. The continuous casting billet conveying device comprises a continuous casting machine tail end roller way, a straight roller way and a shared roller way, the straight roller way and the shared roller way are connected with the outlet end of the continuous casting machine tail end roller way, a first allocating device is arranged between the straight roller way and the shared roller way and used for allocating continuous casting billets, the outlet end of the shared roller way is connected with a first heating furnace, the straight roller way is connected with a rolling line, and the first heating furnace is connected with the rolling line through a first inlet roller way. By means of the device, when multi-strand continuous casting is conducted on double-rolling-line or single-rolling-line production, continuous casting straight rolling billets, uniform-temperature billets and cold billets can flexibly enter rolling lines for production, the requirements of different rolling lines for the temperature and number of different continuous casting billets are met, a production plan is reasonably arranged, and the production efficiency is improved; and heating control over the continuous casting billets can be arranged according to the actual conditions needed by the continuous casting billets and the rolling line, so that energy conservation and emission reduction of the working procedures are achieved, and meanwhile the normal production working procedures and yield of the rolling line under various conditions are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to a continuous casting slab conveying device and method. Background technique [0002] Multi-strand continuous casting machines are commonly used in the industrial production process of iron and steel, non-ferrous metallurgical plants and other places. Multi-strand continuous casting usually refers to the continuous casting process of casting two or more continuous casting slabs on one continuous casting machine at the same time, also known as combination Continuous casting. It improves the production capacity of the continuous casting machine and is easy to match with the large-capacity steelmaking furnace. Multi-strand continuous casting can be divided into two types: one machine with multiple streams and multi-machine with multiple streams. When the multi-strand continuous casting slabs produced are connected to two rolling or single rolling line production line...

Problems solved by technology

[0003] The current continuous casting and direct rolling technology refers to the process of using the waste heat of the continuous casting slab, and the continuous casting slab directly enters the rolling line of the rolling mill for rolling without going through the heating furnace or only through online compensation heating. The corresponding adjustment of the production rhythm of the rolling line will be limited. For example, when the continuous casting machine is temporarily unable to supply hot continuous casting slabs, or when the temperature of the supplied continuous casting slabs is low, the rolling line still needs to continuously obtain high-temperature continuous casting slabs to maintain production requirements. can not satisfy

However, the existing heating furnaces are all designed to meet the requirements of heating cold slabs. When heating continuous casting slabs that only require a small amount of uniform temperature, energy will be wasted. Therefore, more flexible and energy-saving production lines and production methods are required.
