Furnace Hitachi crawler bottom roller surfacing equipment can be used for surfacing welding furnace Hitachi crawler bottom roller surface wear surface, furnace Hitachi crawler bottom roller or workpiece surface surfacing welding wear-resistant, corrosion-resistant, other alloy materials, or repair worn Furnace Hitachi crawler bottom roller. The main welding process adopts the mature flux-cored open arc welding process in the surfacing industry to repair the bottom roller of the furnace Hitachi crawler crane, and cooperates with the automatic welding displacement tool to complete the automatic repair work of the bottom roller of the furnace Hitachi crawler. First, use the spreader to hoist the workpiece to be surfacing between the chuck and the thimble on the bottom roller of the furnace Hitachi crawler crane, and fix the workpiece with the chuck and thimble according to the lathe process, and adjust the lateral movement mechanism and the submerged arc welding gun Welding position, and finally start the welding system, chuck seat rotating mechanism and trolley moving mechanism to implement submerged arc surfacing welding. While the chuck seat rotates, the moving trolley will drive the submerged arc welding torch to automatically move slowly, with each rotation of the workpiece One circle moves a distance of the width of the welding seam to realize the comprehensive movement of the whole set of equipment.
The combined high chromium cast iron furnace Hitachi crawler bottom roller, a new type of furnace Hitachi crawler bottom roller processing technology, is mainly based on different parts of the furnace Hitachi crawler bottom roller, using different technologies to divide it into roller sleeves The two parts of the roller core are made of high chromium cast iron, and the roller core is made of ductile iron or alloy cast iron or cast steel. The process of processing in this way can obtain machines with different performances. Finally, a binder is selected to integrate the roller sleeve and the roller core to complete the production of the entire furnace Hitachi crawler bottom roller.
