Description

Technical Field

[0001] This utility model belongs to the field of metallurgical equipment technology and relates to a steel tapping machine support arm for a pusher-type heating furnace. Background Technology

[0002] Medium and heavy plate heating furnaces use a pushing method to heat slabs. As the furnace's service life extends, the refractory material in the high-temperature zone at the tapping end is prone to detachment due to the vibration of the pushing action, further exacerbating damage to the sliding block. In severe cases, the entire sliding block may detach, causing the slab tapping height to drop by 10-30mm compared to normal. At this point, the upper surface of the wear-resistant plate on the tapping machine support arm is already higher than the lower edge of the slab. Forcing tapping at this point can cause severe scratches on the lower surface of the slab, leading to product defects. In more serious cases, it can cause jamming at this point, easily leading to serious production accidents such as bending and cracking of the water beam, posing an uncontrollable risk to the stable operation of the heating furnace.

[0003] In addition, the burnt-out and detachment of the water beam slider requires a temporary shutdown for maintenance, emptying the slabs in the furnace, replacing the sliders at the burnt-out locations, and recasting to resume production. The estimated cycle is 5-10 days, which disrupts normal production and causes losses in output and costs. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the background technology by providing a pusher-type heating furnace tapping machine support arm.

[0005] Therefore, the present invention adopts the following technical solution:

[0006] A steel tapping machine support arm for a pusher-type heating furnace includes a support arm with a first wear-resistant block installed on its upper surface. The first wear-resistant block is located at the end of the support arm. The upper surface of the first wear-resistant block includes a horizontal support surface and an inclined connecting plate surface. A plurality of second wear-resistant blocks are provided on one side of the first wear-resistant block. The second wear-resistant blocks are installed on the support arm and arranged along the length of the support arm. The upper surface of the second wear-resistant blocks is horizontally arranged and is located in the same horizontal plane as the horizontal support surface.

[0007] Furthermore, a plurality of support rollers are provided on the inclined connecting plate surface along the length direction of the inclined connecting plate surface, and the support rollers are arranged along the width direction of the inclined connecting plate surface.

[0008] Furthermore, the inclined plate surface is provided with a plurality of arc-shaped slots that correspond one-to-one with the support rollers, and the support rollers are located in the corresponding arc-shaped slots.

[0009] Furthermore, each side of the first wear-resistant block is provided with a mounting plate, and the mounting plate is provided with a plurality of through holes corresponding one-to-one with the support rollers, and the ends of the support rollers pass through the through holes.

[0010] Furthermore, the mounting plate is provided with mounting holes, and the first wear-resistant block is provided with screw holes corresponding to the mounting holes. A fixing bolt is provided in the screw hole and passes through the mounting hole.

[0011] Furthermore, the inclined connecting plate surface forms an angle of 10-30 degrees with the horizontal plane.

[0012] The beneficial effects of this utility model are as follows: by setting an inclined connecting plate surface on the first wear-resistant block, the height of the end of the first wear-resistant block is reduced, which can effectively prevent accidents such as jamming caused by the reduction of the billet's steel output height, effectively prevent equipment damage, reduce equipment maintenance time, and improve production efficiency; the structure is simple and the method of use is convenient.

[0018] The present invention will now be described in detail with reference to the accompanying drawings:

[0019] like Figure 1-4As shown, a steel tapping machine support arm for a pusher-type heating furnace includes a support arm 1. A first wear-resistant block 2 is installed on the upper surface of the support arm 1. The first wear-resistant block 2 is located at the end of the support arm 1. The slab being tapped is first pushed onto the first wear-resistant block 2 and then formed by the support arm 1. The upper surface of the first wear-resistant block 2 includes a horizontal support surface 201 and an inclined connecting plate surface 202. The inclined connecting plate surface 202 is located at the end of the first wear-resistant block 2, and the inclined connecting plate surface 202 forms a 10-30° angle with the horizontal plane. The angle between the first wear-resistant block 2 and the inclined connecting plate 202 reduces the height of the end of the first wear-resistant block 2, making the height of the end of the first wear-resistant block 2 lower than the slab tapping height. When the refractory material at the tapping end falls off, causing the slab tapping height to drop, the slab can move through the inclined connecting plate 202 to the horizontal support surface 201 at the top of the first wear-resistant block 2, and then tap normally onto the support arm 1, effectively preventing the slab from getting stuck when moving to the support arm. Multiple second wear-resistant blocks 3 are provided on one side of the first wear-resistant block 2. In this embodiment, three second wear-resistant blocks 3 are provided. The second wear-resistant blocks 3 are installed on the support arm 1 and arranged along the length of the support arm 1. The upper surface of the second wear-resistant blocks 3 is horizontally positioned and is located in the same horizontal plane as the horizontal support surface 201. Both the first wear-resistant block 2 and the second wear-resistant block 3 are made of existing conventional support arm materials and are installed on the support arm 1 in the existing conventional support arm manner. To reduce the impact between the slab and the inclined connecting plate... To reduce friction between the two surfaces, multiple support rollers 4 are provided on the inclined connecting plate surface 202 along its length and width. When the slab moves along the inclined connecting plate surface 202, the support rollers 4 can support and rotate the slab, reducing friction. Specifically, the inclined connecting plate surface 202 is provided with multiple arc-shaped grooves 5 corresponding to the support rollers. The support rollers 4 are located in the corresponding arc-shaped grooves 5. At the same time, a side baffle 6 is provided on each side of the first wear-resistant block 2. The side baffle 6 is provided with mounting holes 7. The first wear-resistant block 2 is provided with screw holes 8 corresponding to the mounting holes 7. The screw holes 8 are provided with fixing bolts 9. The fixing bolts 9 pass through the mounting holes 7 and the side baffles 6 are installed on the first wear-resistant block 2 by the bolts 8. The ends of the support rollers 4 abut against the side baffles 6. The side baffles 6 can prevent the support rollers 4 from coming out of the arc-shaped grooves 5.

[0020] The method of using this utility model is as follows:

[0021] During tapping, if the refractory material in the high-temperature area at the tapping end is prone to falling off, causing the slab tapping height to drop by 10-30mm compared to the normal state, the slab can move onto the inclined contact plate surface 202 of the first wear-resistant block 2 during the movement process. It can then move on the inclined contact plate surface 202 and move onto the second wear-resistant block 3 via the horizontal support surface 201. When the slab moves on the inclined contact plate surface 202, the support roller 4 contacts and rotates with the lower surface of the slab, effectively reducing the friction between the lower surface of the slab and the front end of the slab and the inclined contact plate surface 202. Using this support arm can effectively prevent the slab from getting stuck between the support arm due to the drop in tapping height, which could cause an accident. It also reduces the time required for the water beam slider to be repaired.
