Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of trolley-type resistance furnaces, and in particular to a trolley-type resistance furnace for producing high-chromium cast iron composite rolls. Background Technology
[0002] High-chromium cast iron composite rolls are high-performance rolls designed specifically for the steel rolling industry. They are characterized by achieving a balance between wear resistance, thermal crack resistance, and economy through material composites and advanced processes. High-chromium cast iron composite rolls are rolls with high-chromium white cast iron as the outer layer and ductile iron or high-strength gray cast iron as the core, which are combined into one roll through centrifugal composite casting.
[0003] For example, the trolley-type resistance furnace disclosed in the utility model patent application number CN202421112555.0 represents a type of prior art. Its main structure includes a resistance furnace, a heat insulation layer, a track, a trolley, wheels, an electric heating plate, a heat-conducting plate, a temperature sensor, and a conveying pipe. The function of the trolley-type resistance furnace is realized through the cooperation of the resistance furnace, heat insulation layer, track, trolley, wheels, electric heating plate, heat-conducting plate, temperature sensor, and conveying pipe.
[0004] Because the high-chromium cast iron composite roll is cylindrical, when the high-chromium cast iron composite roll is transported into the furnace by a traditional bogie-type resistance furnace, the high-chromium cast iron composite roll will roll off the bogie. Furthermore, after the high-chromium cast iron composite roll is heated, the temperature inside the bogie-type resistance furnace is still relatively high, making it difficult for the traditional bogie-type resistance furnace to utilize the residual heat. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a trolley-type resistance furnace for producing high-chromium cast iron composite rolls. The high-chromium cast iron composite rolls are placed on limiting mechanisms to prevent slippage during transportation. After heating, a heat exchange mechanism is activated to exchange heat within the heating mechanism. The heated water and steam are then discharged through the heat exchange mechanism for heat utilization, thus improving the practicality of the equipment.
