Description

technical field [0001] The invention relates to the technical field of high-temperature molten salt erosion equipment, in particular to an experimental device for simulating a high-temperature molten salt erosion environment. Background technique [0002] Corrosion, wear and protection have always been subjects of great concern in various industrial fields. my country is a country that mainly uses thermal power generation. In order to make full and reasonable use of coal resources, a large amount of low-quality coal with high ash content is used in power plant boilers. Therefore, the pipes of power plant boilers often suffer from high-temperature erosion, wear and thermal corrosion, causing the pipe wall to become abnormally thinned and fail prematurely. Coating technology for wear resistance. Simulating the wear and corrosion of components working in an erosive environment is of good guiding significance to predict the service life of the coating and to develop a more cor...

Problems solved by technology

The traditional thermocouple has a slow heating rate, poor heat preservation effect, and unsatisfactory simulation effect. It is necessary to have a set of temperature control and heating device with a fast heating rate and good heat preservation effect, and configure the erosion material with a specific molten salt ratio to heat the coating. Can simulate the corrosive environment of power plant boilers operating in high-temperature erosive environments
