Currently, China has the strongest and strictest requirements for energy conservation and environmental protection in the metallurgical industry. Therefore, in order to meet the requirements of low-carbon emission reduction and achieve sustainable development, it is imperative to adopt new technologies for rolling steel heating furnaces. This means that the design and technical performance of many related machines must be improved.

The hydraulic furnace repairing rig is an essential equipment for the construction of the converter in the metallurgical industry. It is a special equipment and is used when the converter is built. The furnace repairing rig is mainly composed of an upgrade device, a hoisting device, a frame, a wheel assembly device and a lifting device hydraulic system. During the operation, the furnace repairing rig is located on the track directly below the masonry converter. The hydraulic station drives 3 to 4 cylinders to lift the table. The hoisting lifting system is responsible for driving the material transfer platform to realize material transfer between the ground and the working platform. For relatively large converters, the larger furnace repair mechanism is even more important because the inner diameter and height of the converter are too large. The repairing rig produced by Hebei Hong Yuan Hydraulic Machinery Co., Ltd. has the characteristics of reasonable structure, durable body, and stable and reliable operation system. The furnace repairing rig has the stretching platform, the upper platform, the supporting device, the telescopic ladder, the supporting oil cylinder, the flat cylinder and other components. It effectively increases the working range of the staff and improves the safety of the operators.
