Problems solved by technology

During the process of the slab hot delivery system, the oxide scale will fall off due to the friction between the slab and the roller table, the collision between the slabs, the collision between the slab and the buffer, etc., and the time is long under the roller table of the slab hot delivery system. There is a large amount of iron oxide scale, and generally the site is cleaned manually, not only the amount of cleaning is large, but also the space for cleaning the iron oxide scale is small, and it is easy to cause problems such as difficult cleaning and unclean cleaning

[0024] In the slab hot delivery system, the motor 3 drives the hot delivery roller table 2 to transport the slab 1 from the continuous casting process to the steel rolling process, such as Figure 1 to Figure 4 As shown, a plurality of motors 3 are supported by concrete or other devices, and drive a plurality of rollers to rotate, thereby conveying the cast slab. The first belt conveyor 4 and the second belt conveyor 11 are installed below the hot-feeding roller table 2 and parallel to the direction of the hot-feeding roller table. The belt width is 800mm, the maximum temperature resistance is 250°C, and the running speed is 0.8m / s . And, the first belt conveyor 4, the second belt conveyor 11 have an interval at the support beam 9 of the hot delivery roller table 2, but the interval between the first belt conveyor 4 and the second belt conveyor 11 can also be set at the hot delivery. For other positions of the roller table, as long as there is space to move the hopper transpo...

[0028] For continuous loading and unloading, two hoppers can be set on the hopper transport vehicle, and a cantilever crane 51, 52 is respectively set on both sides. Such as Figure 5 , Image 6As shown, when the hopper transport vehicle moves to the loading station, the hopper 82 is under the support beam 9, and the oxide scale is first collected in the hopper 82. When the scale in the hopper 82 is full, the hopper transporter moves to the left to the lifting station 1, while the hopper 81 is located under the support beam 9, and the cantilever crane 52 lifts the hopper 82 to the transport vehicle 10 for transport. , and place a new hopper 82 at the original hopper 82 place. And the hopper 81 can also continue to collect iron oxide scales. After the hopper 81 was collected full, the hopper transport vehicle moved to the right side to the lifting station two relative to the lifting station one on the other side of the heat delivery roller table, so that the hopper 82 was po...

Abstract

The invention provides a device and method for collecting iron oxide scales used in a slab heat transfer system. The device includes: a first belt conveyor and a second belt conveyor arranged below the heat transfer roller table along the direction of the heat transfer roller table, and There is an interval between the first belt conveyor and the second belt conveyor; the hopper transport vehicle is provided with the first hopper for containing the iron oxide scale, and the hopper transport vehicle moves along the direction perpendicular to the heat delivery roller table so that the first hopper is in the position of When it is below the interval, it will arrive at the loading station; cantilever crane, the cantilever crane is located next to the hot delivery roller table, and the hopper transport vehicle moves to the hoisting range of the cantilever crane along the direction perpendicular to the hot delivery roller table, that is, it reaches the hoisting station. Among them, the hopper transport vehicle moves to the loading station, collects the iron oxide scale generated by the billet, and transports the collected first hopper to the lifting station, and the cantilever crane lifts the first hopper to the transport vehicle for transport. The invention improves the collection rate of iron oxide scale in the heat delivery system, and effectively reduces the labor intensity of workers on site.

Description

technical field [0001] The invention discloses a device and method for collecting iron oxide scales used in a slab hot delivery system, and belongs to the technical field of continuous casting technology and comprehensive utilization of resources. Background technique [0002] Iron and steel enterprises are the basic industry of the national economy. Under the situation of rapid development of the national economy, steel production has been continuously increasing in recent years. In 2015, my country's crude steel production reached 8.04×10 8 t / a, accounting for 49.5% of global crude steel production. [0003] With the development and maturity of continuous casting technology, the continuous casting slab hot charging and hot delivery technology, which makes full use of the continuous casting slab's own heat energy, has become one of the important means of energy saving and consumption reduction in steel production enterprises. Oxidized iron scale is the oxide produced by th...
