Emergency plugging mechanical plug for ferronickel heating furnace

Abstract

The invention discloses an emergency plugging mechanical plug for a ferronickel heating furnace. A steel plate is fixedly installed on the right side of a plug body, and a steel pipe is welded to the right side of the steel plate. The emergency plugging mechanical plug comprises a transmission inner threaded pipe, an outer connecting sleeve and a button. The transmission inner threaded pipe is in threaded connection with the steel pipe, the right side of the transmission inner threaded pipe is in threaded connection with a transmission outer threaded pipe, and the transmission outer threaded pipe is connected with a drill rod of an external trepanning machine. The outer connecting sleeve is arranged on the surface of the plug body in a sleeving mode, and a deep groove is formed in the outer connecting sleeve. The button is movably installed in the outer connecting sleeve. According to the emergency plugging mechanical plug for the ferronickel heating furnace, the steel pipe is welded to the rear portion of the plug body, then the steel pipe is connected with the drill rod of the trepanning machine through the transmission inner threaded pipe and a transmission outer threaded pipe, the drill rod can be accurately pushed into a slag iron hole through rotation of the trepanning machine and a large arm, and then the plug is beaten into the slag iron hole through the rapping function of the trepanning machine. Sag iron is prevented from flowing out.

Description

technical field [0001] The invention relates to the field of nickel-iron submerged arc furnace emergency technology, in particular to a hole-blocking mechanical plug for emergency nickel-iron submerged arc furnace. Background technique [0002] In the production operation of the submerged arc furnace, we are faced with the process of slag and iron plugging every day. Once the slag and iron hole cannot be blocked, it will cause huge property losses, and even cause personal injury. Now Once the plugging of the slag iron hole fails and the plugging cannot be blocked in the stage, artificial plugging is often used for emergency rescue. Manual plugging is very dangerous, so mechanical plugging is required. [0003] And existing nickel-iron submerged arc furnace emergency plugging mechanical plug also has certain danger during operation, and existing nickel-iron submerged arc furnace emergency plugging mechanical plug does not have a good shell To protect the plug, the plug may b...
