This paper analyzes the causes of accidents of the spindle clamping device of a certain finishing mill,and makes improvement in order to ensure stable clamping and effective and reliable automatic roll changing,avoid accidents such as falling of spindle and interference during roll assembly,shorten automatic roll changing time and ensure stable operation of the production line.
This paper studies the low voltage ride through technology of the photovoltatic power plant on the basis of control algorithms and hardware addition while considering the grid connection structure of the high-power photovoltaic power plant,in order to provide reference for research and construction of low voltage ride through of the photovoltaic power plants.
This paper analyzes the corrosion mechanism and influencing factors of supercritical water oxidation,and introduces the corrosion behaviors of different engineering materials.Since no material has been found with corrosion resistance under all conditions,suggestions for improving the process and structure design of supercritical water oxidation are proposed.
In order to solve the severe wearing problem of the side guide in front of the coiler of hot rolling mill,this paper proposes the innovative method of changing the traditional"fixed position"friction into"variable position"friction.Practical results show that this method can significantly prolong the online service life of the side guide and improve the strip quality.
According to the technical requirements of inner wall overlay welding of small pipes of nuclear power and petrochemical pressure vessels,a multifunctional digital straight pipe overlay welder that is easy to operate,and can provide multiple functions is designed to effectively improve production efficiency and product quality.The welder is adopted for overlay welding of the corrosion-resistant layer of the inner wall of small pipes,and can meet the technical requirements of the products.
