Embodiment Construction

[0019] The following is based on Figure 1-2 The present invention is further described.

[0020] figure 1 The middle blade 4 is flat, and the upper and lower ribs 2 of the blade along the length direction are respectively two faces. Along the length direction, the end far away from the cutter head 3 is provided with a rectangular oval hole or a waist-shaped hole 1, and the semicircle of the waist-shaped hole 1 A clearance fit is used between the diameter and the blade shaft, and the diameter of the semicircle is larger than the diameter of the blade shaft.

[0021] figure 2 for figure 1 The front view of the middle blade 4 is also a structural dimension diagram. In order to facilitate the return of the blade, the length direction of the blade is designed as two surfaces up and down, so that the whole blade becomes flat. In this embodiment, the thickness of the preferred blade is 22mm , and can also be adjusted as needed. In order to reduce the resistance of the blade mo...

Abstract

The invention discloses a blade for a slab deburring machine and a manufacturing method thereof. The blade is characterized in that a substrate of the blade is prepared from 6CrMnSi2Mo1V, and the substrate is prepared from the following components according to weight percent: 0.40 to 0.70% of C, 0.50 to 1.2% of Si, 0.20 to 0.50% of Mn, 4.00 to 6.00% of Cr, 0.50 to 2.00% of Mo, 0.30 to 1.50% of V,less than or equal to 0.02% of P, less than or equal to 0.02% of S and the balance of Fe and inevitable impurity elements. Biphase hard coatings are applied to the top end surface and edges of the blade, and the blade is put in a vacuum sintering furnace to be sintered after the biphase hard coatings are dried. The blade has the advantages of simple structure and process, unique component and difficulty in peeling and breaking, and the wear resistance of the blade is increased. Compared with a 45 steel blade, the slab deburring requirement can be completely satisfied.

Description

technical field [0001] The invention relates to the technical field of continuous casting slab deburring, in particular to a blade for a slab deburring machine and a manufacturing method thereof. Background technique [0002] The blade is a core device of the deburring machine, and its service life is a key indicator to determine the performance of the deburring machine, so how to improve the service life of the blade is a very important content. Through theoretical analysis, it is found that the blade is repeatedly impacted by the billet at high speed during the working process, and the traditional cutting tool cannot meet the high-precision requirements of billet burr removal, and is prone to wear, peeling and fracture. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a blade for a slab deburring machine, which has a simple structure and unique composition, improves the wear resistance of the blade, and is not e...
