Description

TECHNICAL FIELD

[0002] Big cooling bed is the last procedure on the production seamless steel pipe hot rolling line, after the seamless steel pipe is rolled by the tension reducing machine, the steel pipe is transported to the pre-finishing area through the transport roller way. The first procedure of the finishing process line is cooling, that is, the cooling of the steel pipe is carried out on the cooling bed, and the steel pipe on the big cooling bed is a key link of the steel pipe on the big cooling bed, the steel pipe is pushed to the straightening plate through the steel pushing action, and then is transversely moved to the cooling bed rack through the action of the cooling bed moving beam. Since the temperature of the steel pipe is relatively high, about 600 DEG C, the surface hardness is low, the steel pipe is transported to the big cooling bed by the roller way after being rolled out of the tension reducing machine, and in the transportation process, the steel pipe is sent to the cooling bed through the two actions of descending and ascending of the steel feeding slide plate, and the steel pipe is contacted with the steel pipe and generates sliding friction, which often causes the scratch of the outer surface of the steel pipe, and seriously affects the quality of the steel pipe and the equipment failure rate.

[0003] The scratch quality problem of the steel pipe on the big cooling bed has been a difficult problem. From 2010 to 2020, the scratch quality problem of the steel pipe on the big cooling bed often occurs every year, which leads to a large number of steel pipes to be taken off line for grinding every year, and when the steel pipe scratch problem occurs every time, the hot rolling production line also needs to be stopped for checking and replacing the steel feeding vertical roll. According to statistics, the average annual steel feeding scratch failure downtime of the hot rolling production line is more than 20 hours, and the direct economic loss is 9.6 million yuan per year according to the calculation of 80 tons of pipe per hour and 6000 yuan per ton of pipe. At the same time, a large amount of manpower and material resources are needed to deal with the scratched off-line pipe, which seriously affects the normal production of the equipment and the product quality. In order to better solve this difficult problem, the causes of the steel feeding scratch and the steel feeding structure are reanalyzed and researched to solve the problem. UTILITY MODEL CONTENTS
