Wide pure nickel strip and large specification wide strip are a kind of widely used market in urgent need of product, it needs to be prepared by smelting large specification big single weight (>5 tons) ingot again processing. But due to the limitation of current production equipment, only small specification nickel electrode can be prepared, and the large specification ingot needs to be group welded as consumable electrode in the process of electroslag remelting, and the large specification ingot smelted exists poor surface quality, cold separation, especially poor transition of electrode group welding stub part, and the risk of fracture is prone to occur during subsequent processing, especially during ultra-thin strip rolling.

[0007] Further, the inclination angle α of the inclined surface is 4°~15°.

[0008] Further, the length of the first clamping plate and the second clamping plate is not greater than the length of the sawing machine clamping assembly.

[0009] The utility model has the advantages of the following:

[0017] The utility model will be described in further detail below in combination with the drawings and examples.

[0018] Please see Figs. 1-3 The utility model discloses a clamp for nickel electrode preparation, specifically includes: first clamping plate 1 and second clamping plate 2, first clamping plate 1 and second clamping plate 2 are oppositely arranged and the inner end face is the inclined plane that is parallel to each other, and are fixed on the sawing machine through the sawing machine clamping assembly 3 set up on the outside of first clamping plate 1 and second clamping plate 2, the inclination angle of inclined plane is alpha, and nickel electrode ingot 4 (namely the ingot obtained by induction smelting) is clamped between first clamping plate 1 and second clamping plate 2 when sawing, so that the end of nickel electrode ingot 4 is in alpha angle with the saw blade on the sawing machine.

[0019] Further, first clamping plate 1 and second clamping plate 2 are same in structure, and the outer end face is the plane that is parallel to each other, the sawing machine clamping assembly 3 is parallel to the outer end face of first clamping plate 1 and second clamping plate 2, and first clamping plate and second clamping plate 2 are fixedly connected with the sawing machine clamping assembly 3 through bolt, so that first clamping plate 1 and second clamping plate 2 are fixed in parallel on the sawing machine clamping assembly 3, and pressure is applied through the hydraulic rod 5 of one side of sawing machine clamping assembly 3.

[0020] Further, the inclination angle of the bevel is 4°-15°, so that the inclination angle of the nickel electrode ingot 4 is 4°-15° when the nickel electrode ingot 4 is located between the first clamp plate 1 and the second clamp plate 2. After the nickel electrode ingot 4 is cut by the clamp, the end portion has a bevel of 4°-15°. The nickel electrode ingots 4 with several end portions having bevels of 4°-15° are welded by the bevels, so that the welded electrode is vertically placed, the welds have an inclination angle of 4°-15° with the ground. When large-scale nickel and nickel alloy ingots are prepared, only the nickel electrode ingots are welded by the bevels. During smelting, the welds can be smoothly melted, without causing metallurgical defects and cold shut. The transition problem of the electrode welding joint is effectively eliminated, the surface of the final ingot is smooth and consistent, the quality of the ingot is greatly improved, the cracking risk in subsequent processing is eliminated, and the yield is improved. When the inclination angle of the bevel is less than 4°, the effect is not good, and when the inclination angle of the bevel is greater than 15°, a large amount of nickel electrode ingots are wasted, so that the economy is poor.

[0021] In addition, in order to ensure that the first clamp plate 1 and the second clamp plate 2 do not affect the normal sawing of the sawing machine, the length of the first clamp plate 1 and the second clamp plate 2 is not greater than the length of the sawing machine clamping assembly 4.

[0022] Preferably, the first clamp plate 1 and the second clamp plate 2 are made of carbon steel or stainless steel. Stainless steel has low cost, is not easy to deform and damage.

[0023] The above is a further detailed description of the utility model in combination with specific preferred embodiments, and cannot be considered as limiting the specific implementation of the utility model to these descriptions. For ordinary skilled persons in the technical field to which the utility model belongs, without departing from the concept of the utility model, a number of simple deductions or substitutions can be made, which should be considered as belonging to the protection scope of the utility model.
