Embodiment 1

[0034] A cleaning method using the adhesive cleaning tool inside the converter tuyere tube of the present invention under manual control, which specifically includes the following steps:

[0035] 1. Manual operation is adopted to realize the horizontal parallel movement of the base assembly, and the base assembly is pushed to the desired position along the guide rail by manual pushing, so that the twist drill bit is aligned with the wind eye to be cleaned;

[0036] 2. Turn on the air cylinder to make the air cylinder generate thrust, which pushes the sliding seat to move forward, and at the same time turns on the air motor to drive the twist drill bit to rotate. When the twist bit drills into the wind hole to be cleaned, it will adhere to the wind hole After the cleaning is completed, the cylinder generates a pulling force to pull the sliding seat to slide backward, and the twist drill exits the wind eye;

[0037] 3. If there are still burrs left in the wind eye after cleaning, remov...

Embodiment 2

[0039] A cleaning method using the adhesive cleaning tool inside the blower tube of the present invention under automatic control, which specifically includes the following steps:

[0040] 1. Move the cleaning tool to the leftmost side of the lateral 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, advancing time, retreating speed, retreating time and the interval between two cleanings of the cylinder, and setting the rotation speed of the air motor, the opening time, and the time interval between two cleaning openings;

[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 a certain angle so that the twist drill bit is aligned Eyes to be cleaned;

[0042] 3. After the co...

Embodiment 3

[0045] A cleaning method using the adhesive cleaning tool inside the blower tube of the present invention under automatic control, which specifically includes the following steps:

[0046] 1. Move the cleaning tool to the leftmost side of the lateral 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, advancing time, retreating speed, retreating time and the interval between two cleanings of the cylinder, and setting the rotation speed of the air motor, the opening time, and the time interval between two cleaning openings;

[0047] 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 a certain angle so that the twist drill bit is aligned Eyes to be cleaned;

[0048] 3. After the co...

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 cleaning tool for bonding inside a blower tube of a converter. Background technique [0002] The matte blowing process is the last process of pyrometallurgical production of blister copper. During the production process, desulfurization and iron removal are carried out and other harmful impurities in the matte are further reduced. Both the desulfurization and iron removal system and the impurity removal system adopt the specifications as PS large-scale converter with 260t / furnace. The entire blowing process is carried out in the converter. The melt is stirred by the gas and a fierce chemical reaction occurs. When the blowing is over, the internal tuyere area will have cold copper bonding. Before entering the next charge, each tuyere must be The eye of the wind should be cleaned again, otherwise it will affect the rhythm of the ...
