Embodiment 1

[0034] A cleaning method using the internal bonding cleaning tool of the converter air eye tube of the present invention under manual control, which specifically includes the following steps:

[0035] 1. Use manual operation to realize the lateral parallel movement of the base assembly, and manually push the base assembly to the required position along the guide rail, so that the twist drill bit is aligned with the wind hole to be cleaned;

[0036] 2. Turn on the cylinder to generate thrust, push the sliding seat forward, and at the same time turn on the air motor to drive the twist drill to rotate. When the twist drill drills into the wind hole to be cleaned, the adhesion in the wind hole will be After the cleaning is completed, the cylinder generates a pulling force, which pulls the sliding seat to slide backward, and the twist drill exits the wind eye;

[0037] 3. If there are still burrs in the cleaned wind eye, remove the twist drill, and manually push the base assembly t...

Embodiment 2

[0039] A cleaning method using the internal bonding cleaning tool of the converter air eye tube of the present invention under automatic control, which specifically includes the following steps:

[0040] 1. First move the cleaning tool to the far left in the horizontal direction, start the controller, and set the speed of each lateral movement of the cleaning tool, the time of lateral movement and the interval between two cleanings on the controller , setting the forward speed of the cylinder, the time of advancement, the retreat speed, the time of retreat and the interval between two cleanings, the speed of the air motor, the opening time and the time interval between two cleanings;

[0041] 2. After the setting is completed, press the controller run button, the controller outputs instructions to the servo motor according to the set speed and time, and controls the servo motor to rotate at a certain angle, so that the twist drill bit is aligned Eyes to be cleared;

[0042] 3...

Embodiment 3

[0045] A cleaning method using the internal bonding cleaning tool of the converter air eye tube of the present invention under automatic control, which specifically includes the following steps:

[0046] 1.

Abstract

The invention discloses a converter wind eye pipe inner bonding cleaning tool. The converter wind eye pipe inner bonding cleaning tool comprises a base assembly, a poking and beating device and a rotation device. The base assembly comprises bearing wheels, guiding wheels, a support and guide rails. The base assembly can transversely move on the guide rails in a reciprocating manner. The poking and beating device is fixedly arranged on the support and comprises an air cylinder, a sliding base, guiding rods and drill rods and is used for poking and beating a converter wind eye. The rotation device comprises a pneumatic motor, a speed reducer, a coupler, a transmission shaft, a rotation rod and a twist drill. The pneumatic motor is fixedly arranged on the sliding base, a rotation shaft of the pneumatic motor is connected with the speed reducer, the torque output end of the speed reducer is connected with the transmission shaft through the coupler, and the transmission shaft is connected with the rotation shaft. The torque is transmitted to the rotation shaft to drive the rotation rod to rotate, and the tail end of the rotation rod is detachably provided with the twist drill. According to the converter wind eye pipe inner bonding cleaning tool, for the problem of wind eye blockage of a PS large converter wind gap, drilling is used for replacing a poking and beating manner, and the technical problem that due to existing design, refractory bricks in a wind eye area in a converter are likely to be damaged abnormally is solved.

Description

technical field [0001] The invention belongs to the technical field of smelting equipment for industrial copper smelting, and in particular relates to a tool for cleaning the internal adhesion of a converter eye tube. Background technique [0002] The matte blowing process is the last process of pyrometallurgy to produce blister copper. During the production process, desulfurization and iron removal are carried out and other harmful impurities in matte are further reduced. The desulfurization and iron removal system and the impurity removal system both adopt the specification of 260t / furnace PS large-scale converter. The whole blowing process is carried out in the converter furnace, the melt is stirred by gas, and a violent chemical reaction occurs. When the blowing is over, there will be cold copper bonding in the inner tuyere area. Before entering the next charge, each tuyere must be closed. Clean up the wind eye, otherwise it will affect the normal production rhythm of...
