Description

[Detailed Description of the Invention] The present invention relates to a device for attaching and detaching siding pipes and siding bricks from the outside of the hearth bottom of a bottom-blowing converter and a top-blowing converter having refining linings on the hearth bottom.

Conventionally, when replacing a bottom blowing tuyere, the hearth bottom is separated, and after transporting the separated hearth bottom to a repair shop, the tuyere pipe is first pulled out, the siding brick is removed or destroyed, and then a new siding brick is installed. This was done by inserting a cider tube.

In this invention, these replacements are performed at the converter operating position.
The present invention provides an apparatus that can perform these series of procedures consistently.

The work of replacing the siding required extremely high precision, and the location was extremely hot, so it was difficult to develop equipment suitable for this task.

In view of these circumstances, the present invention aims to provide a device that can consistently perform tuyere replacement, simplify the replacement work, and ultimately rationalize converter operation and increase productivity. It is.

The present invention will be explained below with reference to FIGS. 1 and 2.

In this figure, the attachment/detachment device A is placed on a cart 2 that moves back and forth with respect to the converter 1.

The desorption device consists of a cylinder 4 that moves the desorption jig back and forth.
, a cylinder 5 for turning, a moving cylinder 6 for moving left and right on a truck, a cylinder 7 for tilting, a cylinder 8 for moving the attachment/detachment device up and down on the truck, and a mechanism for holding the tuyere attachment/detachment jig in a replaceable manner.

Although the examples in FIGS. 1, 2, 3, and 4 show the clamping device 11 as the holding mechanism, the holding mechanism is not limited to this, and other ordinary tightening mechanisms such as bolts and bolts may also be used. may be a mechanism.

The clamp device 11 is fixed to the tip of the forward/reverse cylinder 4 via the mounting seat 3.

In addition to the clamp device, the attachment/detachment jig is replaceably fixed to the front H of a siding brick drawing rod 10 shown in FIG. 5, a siding brick breaking breaker 1, or a brick breaking drill.

12 is a support member installed on the trolley to receive the pulling reaction force; 13
is a protective canopy.

Now, the function of this device is to advance the cart 2 to the tilted converter 1.

Then, using the vertical cylinder 8, the left-right moving cylinder 6, the swing cylinder 5, and the tilting cylinder turf, the clamp device 11 fixed to the tip of the forward-reverse cylinder 4 is positioned at the center of the hearth bottom tuyere, and then the cylinder 4 is moved forward. When the bottom part 9 of the siding tube is gripped and pulled out, a member 12 installed on the cart receives the pulling reaction force.

Next, replace the tuyere pipe drawing jig with the siding brick drawing rod 10 (Figs. 5 and 6) and take it out in the same manner as before.

Furthermore, the installation of the tuyere pipe and siding bricks is carried out in the reverse order to that described above, and it is usually possible to install the tuyere pipe and siding brick as one unit.

As described above, the present invention is a practical device that allows the hearth bottom tuyeres to be easily replaced and installed using a single attachment/detachment device, and can be carried out extremely smoothly.
