Automatic sampling device in front of high-temperature furnace

Abstract

An automatic sampling device in front of a high-temperature furnace comprises a rack, a displacement mechanism and a swing mechanism, the displacement mechanism is arranged on the rack, the swing mechanism is arranged on the displacement mechanism, a drag chain is further arranged on the rack, and two hooks are arranged at the top of the rack at intervals; the automatic sampling device is installed at the front end of a furnace mouth of the high-temperature furnace, the swing mechanism is pushed into the high-temperature furnace through the displacement mechanism, the swing mechanism drives the sampling spoon to be inserted into furnace liquid of the high-temperature furnace and drives the sampling spoon to conduct sampling operation, and therefore automatic sampling of the furnace liquidof the high-temperature furnace is achieved. In the process, an operator is far away from the furnace mouth, the sampling device is operated by the operating handle, and manual sampling is replaced byequipment, so that sampling from the operator to the front end of the furnace mouth is avoided, the distance from the operator to the furnace mouth is increased, the potential safety hazard during manual sampling of the operator is eliminated, and the safety of high-temperature furnace stokehole sampling is greatly improved.

Description

technical field [0001] The invention relates to the technical field of sampling equipment, in particular to an automatic sampling device in front of a high-temperature furnace. Background technique [0002] In the production process of the alloy smelting and casting industry, the composition detection through the sampling method before the furnace is the main means to track the change of the composition of the furnace liquid, and it is also an important basis for adjusting the alloy composition in the furnace liquid to ensure product quality. The traditional sampling method in front of the furnace usually uses a graphite crucible. This method requires the operator to remove the covering material on the furnace liquid, then extend the sampling crucible into the furnace liquid, scoop up the furnace liquid and pour it into a special sample cup. Inside, after cooling, demould and send for inspection. However, before manually sampling from the furnace mouth, the converter furnac...

AI Technical Summary

Problems solved by technology

However, before manually sampling from the furnace mouth, the converter furnace mouth is shaken toward the front of the furnace, and the molten steel flows in the furnace body. In the case of some violent reactions of oxygen and carbon, there is a possibility of slag spraying, which seriously affects the safety of the furnace front operators. Personal safety

[0003] In view of the potential safety hazards that may cause personal injury and death in the existing manual sampling operation technology, it is necessary to design an automatic sampling device in front of the high-temperature furnace
