Problems solved by technology

However, the single processing station RH has the advantages of energy saving, low investment cost, small footprint, and high equipment operation rate. After the emergence of new types such as V-shaped double ladle car type and ladle rotary type, the auxiliary operation time can also be effectively shortened. The single-handling station RH is back to life

Abstract

The invention relates to a method for shortening the replacement time of single-station RH vacuum chambers and an RH vacuum chamber replacement device. According to the method, two original vacuum chamber transporting vehicles of the single-processing-station RH are combined into a long double-vacuum-chamber transporting vehicle, the action that one of the two vacuum chambers operates from a processing station to a standby station and the action that the other of the two vacuum chambers operates from the standby station to the processing station can be completed at the same time, the non-production time of an RH vacuum refining furnace is shortened, and the RH vacuum refining furnace has the advantages of being light in equipment weight, small in total length and large in operation area.

Description

technical field [0001] The invention belongs to the field of steelmaking vacuum refining in the metallurgical industry, and in particular relates to a method for shortening the replacement time of a single-station RH vacuum chamber and an RH vacuum chamber replacement device. Background technique [0002] With the development of the economy, the user's demand for steel products continues to expand, and the requirements for steel quality are also increasing. From the perspective of the process itself and experience, RH (vacuum cycle degassing) series vacuum treatment technology has become one of the effective means to expand the product range and improve product quality. [0003] At present, there are two types of RH vacuum refining furnaces in steel mills: single processing station and double processing station. Generally speaking, since the double processing station RH uses two processing stations alternately, it can save auxiliary operation time such as sitting bag, hangi...
