Tire type steel continuous-casting and continuous-rolling process and device thereof

Abstract

The invention discloses a tire type steel continuous-casting and continuous-rolling process and a device thereof. The process comprises the following steps of: A, a melting pot; B, pouring and boiling; C, tire rotating for crystallization; D, straightening; and E, continuous rolling without torque. The tire type steel continuous-casting and continuous-rolling device comprises a pouring ladle, a casting wheel, a steel belt, tires, a steel belt pressure device, a straightening device and a hydraulic rolling device, wherein the pouring ladle is arranged above the casting wheel, and the steel belt packs the lower semicircle of the casting wheel; the steel belt is closed around the four tires and clings the lower part of the casting wheel through the steel belt pressure device; the steel belt can glue the casting wheel to rotate; and a spraying device is arranged around the steel belt and the casting wheel. According to the process and the device thereof, the continuous-casting and continuous-rolling procedures are greatly decreased, the production cost is reduced, the production efficiency is greatly increased, and the energy consumption is reduced by more than 30%. A mode of steel belt rotating and indirect cooling is adopted, so that the surface of steel has no crack and less oxide skin, and the quality and precision of finished products are increased. The device has a better economic benefit.

Description

technical field [0001] The invention relates to a steel material continuous casting and rolling process, in particular to a belt-type continuous casting and rolling process for steel material and its device. Background technique [0002] At present, the existing wire rod rolling process is to use the continuous casting slab sent from the steelmaking plant. The steel slab coming out of the steelmaking plant is only a semi-finished product. It must be rolled in the rolling mill before it can become a qualified product. First, it enters the heating furnace, after being heated to 1050-1080°C, and then after repeated rolling in the preliminary rolling mill, it enters the finishing rolling mill. Steel rolling belongs to metal pressure processing. In the hot rolling production line, the slab is heated and softened, and is sent to the rolling mill by the roller table, and finally rolled into the size required by the user. [0003] The conventional continuous casting machine uses a ...

Problems solved by technology

The investment of a continuous casting production line plus a general rolling line is more than 250 million; such a high investment and such a complex production line bring high output, but there are intermittent rolling that affects the yield, and the processing of large-section billets and finished products. A series of problems such as high power consumption, long production line, complex technology, and many personnel
