Arrangement structure of double-station RH multifunctional top lance

Abstract

The invention relates to a double-station RH external refining system, in particular to an arrangement structure of a multifunctional top lance in double-station RH external refining. The arrangement structure comprises 2-4 vacuum truck systems which respectively contain vacuum tanks and hot elbows, multifunctional top lance devices, two treatment stations and 2-4 standby stations, wherein the two treatment stations are respectively a first two treatment station and a second two treatment station. The arrangement structure is characterized in that the numbers of the multifunctional top lance devices and the vacuum truck systems are equal, and the structure further comprises translation trolleys with reducing motors, wherein the numbers of the reducing motors and the multifunctional top lance devices are equal; the multifunctional top lance devices are respectively and fixedly arranged on the translation trolleys with the reducing motors; and the multifunctional top lance devices and the vacuum truck systems move under the control of a computer and can switch in the way of reciprocatory translate between adjacent treatment stations or standby stations so as to meet the requirementsfor different smelting processes. The arrangement structure provided by the invention overcomes defects in the prior art.

Description

technical field [0001] The invention relates to a dual-station RH external refining system, in particular to an arrangement structure of multifunctional top lances in the dual-station RH external refining. Background technique [0002] At present, the known double-station RH refining system is divided into four cars and six positions (that is, four sets of vacuum tank car systems are set up, with six process positions, two processing positions and four standby positions), three cars and five positions. position (i.e. set up three sets of vacuum tanker systems, with five process positions, two processing positions and three standby positions) and two-vehicle four positions (that is, set up two sets of vacuum tanker systems, with four process positions, two treatment position and two standby positions), the top gun device and preheating gun device are set independently of each other, the number of top gun and preheating gun device is the same as the number of stations in the d...

AI Technical Summary

Problems solved by technology

[0004] The vacuum treatment of molten steel at the processing position is completed by the top gun device; the heating of the vacuum tank at the standby position is completed by the preheating gun device; the number of top guns and preheating gun devices used online at the same time is the same as the number of online vacuum tanker systems , the redundant top gun device and preheating gun device can only be used as a backup, and their capabilities are not really used; in order to make room for the hoisting of the vacuum tank and the hot bend pipe, the preheating gun must be rotated to the inspection position; according to the traditional top gun and The process layout of the preheating gun will inevitably increase the inventory of spare parts, and at the same time increase the amount of maintenance during normal work, which will increase the operating cost
