Device and method for improving removal efficiency of round billet cutting edge

Abstract

The invention discloses a device and method for improving removal efficiency of a round billet cutting edge, and belongs to a round billet continuous casting machine device and application in the metallurgical industry. The device comprises a casting billet cutting surface detection device, a cutting edge removal scraper device, a cutting edge collection device and a cutting edge pushing device. According to the device and method, the characteristic that the bonding force between the cutting edge and a casting billet is small in a high-temperature state is utilized, after the casting billet iscut, the casting billet is conveyed to the billet discharging direction through a cutting roller way, and after the detection device detects the cutting end face of the casting billet, the cutting edge of the casting billet is completely removed through axial force applied to the front end face and the rear end face of cutting by forward and reverse rotation of the scraper device. By means of theapplication of the device and method, the casting billet can be directly loaded and transported after being discharged out of a burial pit, the transporting speed of the casting billet is greatly increased, potential safety hazards such as burning and heatstroke existing when an edge removal person works in a high-temperature environment are eliminated, the manpower and material resource cost needed by edge removal work is saved, the requirement of the subsequent procedure for the temperature of the casting billet is met, and the quality of the casting billet is guaranteed.

Description

technical field [0001] The invention relates to a device and a method for improving the removal efficiency of round blank cutting tumors, and belongs to the technical field of auxiliary equipment for steelmaking production. Background technique [0002] In recent years, with the rapid development of the railway industry, the number of round billet continuous casting machines for the production of wheel and axle steel in the steel industry has increased day by day. In order to meet the market demand, our factory built a three-machine three-strand round billet continuous casting machine in March 2015. Cutting is an important link in the continuous production of round slabs. During the process of cutting the slabs, the torch cutting machine will form cutting nodules on the lower surface of the first and last ends of the slabs. The cutting nodules not only affect the quality of the slabs but also endanger the equipment of the casting machine. Large domestic steel mills such as ...

AI Technical Summary

Problems solved by technology

The temperature of the slab is as high as 550 degrees after it comes off the line, and the tumor removal personnel work in the off-line area for a long time, which is prone to personal injury accidents such as scalding and heat stroke

Secondly, the operators work in a high temperature environment, which greatly reduces the working efficiency

Thirdly, after the slab is cooled by the slow cooling pit, the cutting nodules attached to the cutting surface of the slab become hard, and the bonding force with the slab becomes stronger, making it more difficult to manually clean the cutting nodules

After the slow cooling time is up, the casting slab needs to be shipped out of the pit in time. Due to the low efficiency of manual removal of tumors, the casting blanks cannot be shipped in time, and tumor removal has become a bottleneck restricting production.

On the other hand, if you encounter a slab that needs red delivery, it takes a long time to manually remove the tumor, which increases the temperature drop time of the slab in a normal temperature environment, affects the formation of the slab structure, and causes the quality of the slab to decline
