Description
Technical Field
The utility model relates to a steelmaking continuous casting slab field especially relates to a slab turns over base instrument.
Background
Continuous casting is the main cast steel production method at present. In 2004, the continuous casting ratio in China already reaches 96%. Most iron and steel enterprises realize full continuous casting. Due to the influence of steel grade and process, the surface of a part of continuous casting slab has certain quality defects and can be sent down after being cleaned. When the quality defect of the lower surface of the continuous casting slab is cleaned, the slab needs to be turned, but due to the fact that the length, the width and the weight of the continuous casting slab are large, special equipment needs to be used for turning the continuous casting slab. The traditional hydraulic slab blank turning machine has the disadvantages of complex structure, huge investment, high operating cost, low blank turning speed, more faults, periodic maintenance and complex operation, and greatly influences the cleaning and production of continuous casting slabs. Other blank turning tools are bound by clamps or steel ropes, turning is completed by means of a crane and the self gravity of the plate blank, and the turning speed is high. And part of the high-carbon steel plate blank is easy to brittle failure or crack in the turning process. If the turnover area has hard objects hit by the turnover slab, the hard objects are easy to splash, and potential safety hazards exist.
Disclosure of Invention
The utility model provides a slab turns over base instrument can solve the problem that exists among the continuous casting slab upset process. The utility model relates to a slab turns over base instrument places the continuous casting slab in the blank field and is used for on the slab of foreshadowing. The body of the slab blank turning tool is manually clamped on the longitudinal side face of the head or the tail of the continuous casting slab, the body is connected with two iron chains through connecting pieces, and the iron chains are connected with respective steel ropes. When turning over the blank, the steel rope is hoisted by a crane to erect the continuous casting slab, and the crane drives the continuous casting slab to one side to incline the casting slab to one side. And then the lifting hook is lowered to slowly lay the casting blank flat, and the blank turning operation can be finished. The slab turns over base instrument simple structure, the flexible operation turns over the base in-process, and the upset speed can be controlled by people, can not appear turning over the base too fast, avoids the slab to empty the damage or pound the well hardiness of its and appear splashing naturally.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a slab blank turning tool comprises a blank turning body, a handle, connecting pieces, iron chains and steel ropes, and is characterized in that the blank turning body is of a groove shape, the handle and the connecting pieces fixed through bolts are welded on the blank turning body, the blank turning body is connected with the two iron chains through the connecting pieces, and the iron chains are connected with the respective steel ropes.
The thickness of the turning blank body is 50 mm.
Compared with the prior art, the beneficial effects of the utility model are that:
1) the slab blank turning tool is simple in structure, convenient to install, flexible to operate, low in investment, low in operating cost and low in fault rate, slab cleaning time is saved, and slab cleaning efficiency is improved.
2) According to the slab turning tool, the slab turning speed is controllable, brittle fracture or cracks caused by impact force on the slab due to the fact that the slab is too fast in the slab turning process are prevented, and loss is reduced.
3) The slab turns over base instrument prevents that the slab from falling and pounding well hardwares and appearing splashing, reduces the incident hidden danger, improves the safe operation rate.

Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
as shown in fig. 1, a slab turning tool comprises a slab turning body 1, a handle 2, a connecting piece 3, iron chains 4 and steel ropes 5, wherein the slab turning body 1 is in a groove shape, the handle 2 and the connecting piece 3 fixed through bolts are welded on the slab turning body 1, the slab turning tool is connected with the two iron chains 4 through the connecting piece 3, the iron chains 4 are connected with the respective steel ropes 5, the slab turning body 1 of the slab turning tool is manually clamped on the longitudinal side face of the head or the tail of a continuous casting slab 7, the slab turning body 1 is connected with the two iron chains 4 through the connecting piece 3, and the iron chains 4 are connected with the respective steel ropes 5. The steel rope 5 is lifted by using the crane 6 when the slab is turned, the continuous casting slab 7 is erected, the crane 6 drives to one side, the slab 7 inclines to one side, then the lifting hook is lowered, the casting slab is slowly laid, and the slab turning operation can be completed, wherein the handle 2 on the slab turning body 1 is used for manual holding, the slab turning body 1 is clamped on the continuous casting slab 7, in the process of lowering the lifting hook, the iron chain 4 and the steel rope 5 can slowly lay the erected slab 7, and the slab 7 is prevented from being damaged or splashed when the slab 7 is hit due to natural dumping.
As shown in fig. 2, the thickness of the turning blank body 1 is 50 mm.
The following examples are carried out on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following examples. The methods used in the following examples are conventional methods unless otherwise specified.
[ examples ] A method for producing a compound
The slab 7 is flatly placed on the paved slab, the slab turning body 1 is clamped on the side face of the slab 7, the connecting body 3 is connected with the iron chain 4, and then the steel rope 5 connected with the iron chain 4 is hung on the lifting hook.
The slab 7 is lifted to be in an upright state by using the bridge crane 6, and then the crane 6 is driven to one side to drive the slab 7 to turn over, so that the slab turning operation is completed.
The utility model discloses in use, simple structure, convenient operation, the small investment, the working costs is low, has saved slab cleaning time, improves the cleaning efficiency of slab, avoids the slab to empty the damage to it naturally, eliminates unsafe factor.
