Problems solved by technology

[0003] Imported ion igniters are generally divided into several sections and assembled on site due to the limitation of transportation length. The assembly workload is heavy and the precision requirements are high.
When assembling the ignition needle of the igniter and the connecting steel wire of the transformer, there are multiple joints. These joints will generate abnormal high-voltage discharge when the igniter is working, which will affect the stability of the igniter.

Abstract

The invention relates to a long igniter which comprises a barrel body. A circuit board and a transformer are fixed in the barrel body, one end of the barrel body is connected with an electrical plug, the other end of the barrel body is sequentially connected with an installing flange and an outer tube, a gas tube is arranged in the outer pipe, an air connector and a gas connector are arranged on the installing flange, the air connector is communicated with the outer tube, and the gas connector is communicated with the gas tube. The outer end of the gas tube is connected with a spray head, an ignition needle and a detection bar are arranged nearby the spray head, the ignition needle is connected with the transformer through a detection bar connecting steel wire and a detection bar cable, and the detection bar is connected with the circuit board through an ignition needle connecting steel wire and an ignition needle cable. Most parts of the detection bar connecting steel wire and the ignition needle connecting steel wire are replaced by the detection bar cable and the ignition needle cable, only a small part of connecting steel wires located in a high-temperature region is reserved, the joint number of the connecting steel wires is decreased, the stability of the igniter is improved, and the cost of the igniter is reduced.

Description

technical field [0001] The invention relates to a RH refining furnace, in particular to a long igniter used in the oxygen lance equipment of the RH refining furnace. Background technique [0002] At present, there are more than 100 domestic steel mills adopting RH refining technology. The ion igniter matched to the oxygen lance equipment of the RH refining furnace brings a large amount of objective rigid demand due to its own consumable characteristics. Usually, the annual demand of large steel plants is nearly several hundred sets. Since there are currently no manufacturers of such ion igniters in China, steel mills now rely on imports, which greatly increases the production cost of steel mills. [0003] Imported ion igniters are generally divided into several sections and assembled on site due to the limitation of transportation length. The assembly workload is heavy and the precision requirements are high. When the ignition needle of the igniter and the connecting steel...
