[0002] Furnace rolls generally work continuously in an environment full of corrosive media at a high temperature of 800-1200 °C and a pressure of 2.0-4.0 MPa. The use environment is very harsh, but the design life should reach 100,000 hours. The existing furnace rolls usually use rolling Due to the limitations of the rolling production process, the grains of the product are relatively fine, the C content of the material can only be below 0.2, and microalloys such as Ti, Zr, and Nb cannot be added, which affects its high temperature resistance and Improvement of service life

Abstract
The invention relates to a high-strength high-alloy furnace roller production equipment system. The high-strength high-alloy furnace roller production equipment system mainly comprises smelting equipment, a roller body centrifugal casting device, a roller neck static casting device, a shot blasting device, a roller body straightening device, performance testing equipment of a roller body and a roller neck casting, roller body machining equipment, roller neck machining equipment, roller body and roller neck assembly welding equipment, a shaft head machining workpiece, and roller body and roller neck assembly and shaft head assembling and welding equipment, and is further provided with a full-fiber energy-saving box type resistor furnace for carrying out solid solution heat treatment on the casting; preferably, the smelting equipment is an IGBT medium-frequency induction smelting furnace; an inverter of the IGBT medium-frequency induction smelting furnace adopts an IGBT module; surfacing equipment also can be arranged to carry out surfacing on partial or whole surface of a roller body, and a coating used for surfacing adopts a specific ratio, so as to be adapted to use environments and performance requirements of the roller body. The furnace roller prepared by the system is good in high temperature resisting performance and long in service life, and the energy consumption in a preparation process can be easily reduced.
Description
technical field [0001] The invention relates to a high-strength and high-alloy furnace roll production equipment system. Background technique [0002] Furnace rolls generally work continuously in an environment filled with corrosive media at high temperature of 800-1200 ℃ and pressure of 2.0-4.0MPa. The use environment is very harsh, but the design life should reach 100,000 hours. The existing furnace rolls usually use rolling. Due to the limitation of the rolling production process, the grains of the product are relatively fine, the C content of the material can only be below 0.2, and micro-alloys such as Ti, Zr, Nb cannot be added, which affects its high temperature resistance and performance. Increased service life. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-strength and high-alloy furnace roll production equipment system. The furnace roll prepared by using this system has g...
