Vertical conveying system for core winding frame

Abstract

The invention provides a vertical conveying system for a core winding frame, which comprises the core winding frame, a lifting roller machine, a turning roller machine, a conveying roller machine and a rotating roller machine, wherein, the core winding frame bears coils; the lifting roller machine clamps and lifts the core winding frame to a coil collecting drum for bearing the coils and then returns and delivers the core winding frame; the turning roller machine turns over the delivered core winding frame to a horizontal position; the conveying roller machine horizontally conveys the core winding frame; and the rotating roller machine horizontally rotates 90 degrees. In the invention, the coils are born by the equipment with simple structures, thus being easier to control, lowering faultrate of the equipment and being more beneficial to normal operation of the whole process; in addition, the conveying roller machine is arranged between the lifting roller machine and the turning roller machine for conveying the core winding frame carrying the coils, which avoids direct contact between the coil surfaces and the conveying roller machine so as to stably control the surface quality of the coils. In addition, the conveying system of the invention is equipped with the rotating roller machine for changing the delivery direction of the core winding frame, which greatly saves plant space on the premise of guaranteeing sufficient cooling sections.

Description

technical field [0001] The invention relates to the fields of iron and steel and metallurgy, in particular to a conveying technology. Background technique [0002] In the wire rod rolling project of the existing steelworks, the commonly used process flow is as follows: figure 1 Shown: [0003] First, rough materials such as iron ore and steel billets are sent to the heating furnace for high temperature treatment and initially form slabs; then these slabs are sequentially subjected to rough rolling, intermediate rolling, pre-finish rolling, and finish rolling to form Formed coils; Next, these formed coils are sent to the loose coil air-cooling system for air-cooling and cooling treatment, so that the temperature is partially reduced. For a 2-ton coil (the specification is usually Φ1250×Φ850L= 3000mm), the temperature after air cooling is about 600 degrees Celsius. These coils are then sent to the coil collection station, where the main equipment in operation is the double-...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned double-arm mandrel system is a set of equipment integrating mechanical, electrical, and hydraulic controls. Its structure is complex and its integration is relatively high. In actual use, the failure rate is also relatively high. The relatively high level of integration brings difficulties to rapid maintenance and will cause the entire process to fail to work normally

Also, it is difficult to replace the mandrel, which is constantly in contact with the coil

[0005] In addition, in the above process, after the coil leaves the mandrel of the double-arm mandrel system, it will directly contact the subsequent equipment, which will wear the surface of the coil, thereby greatly affecting the appearance quality of the coil, especially when the rolling mill When making high-quality smooth coils, the use of equipment in the above process cannot stably control the surface quality of the coils

[0006] In addition, the coil temperature after air-cooling treatment is still around 600 degrees Celsius, which requires sufficient cooling sections in the subsequent process. Since the P / F line cooling system can only be arranged along the length direction, it will undoubtedly occupy more workshops space
