Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel belts, in particular to a wear-resistant stainless steel belt of a ferrous metal smelting and rolling product. Background Art

[0002] Stainless steel strip is a metal product manufactured during the ferrous metal smelting and rolling process. First, the stainless steel raw material is melted at high temperature to form stainless steel liquid. At this stage, the properties of the final product can be adjusted by adding different alloying elements. The molten stainless steel is then cast into preliminary shapes, such as billets or plates. Next, these billets or plates are hot-rolled at high temperatures to reduce their thickness and increase their toughness. The hot-rolled products are then further thinned by a cold rolling process to achieve the desired thickness. The cold rolling process can increase the strength and hardness of the material. After cold rolling, the stainless steel strip may undergo heat treatment, such as annealing, to restore its flexibility. Finally, depending on the application requirements, the stainless steel strip may undergo surface treatment, such as polishing, plating or painting, as disclosed in the authorization announcement number CN216579547U A wear-resistant stainless steel belt of ferrous metal smelting and rolling product, comprising a stainless steel belt base, the upper part of the stainless steel belt base is fixedly connected with a high wear-resistant base, and the lower part of the stainless steel belt base is fixedly connected with a high wear-resistant expansion layer; the high wear-resistant base comprises a wear-resistant layer 1, the bottom of the wear-resistant layer 1 is fixedly connected with a wear-resistant lining layer 1, the bottom of the wear-resistant lining layer 1 is fixedly connected with an elastic layer 1, and a wear-resistant lining layer 2 is fixedly connected between the elastic layer 1 and the stainless steel belt base, etc., which greatly improves the wear resistance by adopting high-toughness cemented carbide and tungsten carbide infiltrated steel-based alloy, but the cross-sectional shape of the stainless steel belt base in this technical solution is a long rectangular structure, and its deformation resistance is poor, especially the edge line of the stainless steel belt is easily deformed under twisting or bending stress, thereby generating cracks at the corners or edges.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4The utility model provides an embodiment: a wear-resistant ferrous metal smelting rolled stainless steel belt, comprising an inverted I-shaped stainless steel belt core 1 and an upper U-shaped steel belt 2 and a lower U-shaped steel belt 3 installed on the upper and lower surfaces of the inverted I-shaped stainless steel belt core 1, and the outer peripheral surfaces of the upper U-shaped steel belt 2 and the lower U-shaped steel belt 3 are coated with a wear-resistant layer 4;

[0018] The cross-sectional shape of the inverted I-shaped stainless steel strip core 1 can provide greater bending stiffness and strength compared to a rectangular cross-section, and the flange of the I-shaped cross-section can withstand greater tensile and compressive forces, thereby reducing deformation when subjected to bending forces;

[0019] The lower surface of the upper U-shaped steel strip 2 and the upper surface of the lower U-shaped steel strip 3 are both provided with rectangular grooves of the same length as themselves, and the rectangular grooves are used to improve the fitting strength of the upper U-shaped steel strip 2 and the lower U-shaped steel strip 3;

[0020] The outer peripheral surface of the inverted I-shaped stainless steel belt core 1 is provided with a carburized layer 101. The inverted I-shaped stainless steel belt core 1 after carburization can increase its surface compressive strength, thereby improving the fatigue strength of the steel belt, so that the steel belt can maintain its core toughness while increasing its surface hardness, which helps to resist the impact and sudden force.

[0021] The wear-resistant layer 4 is a ceramic coating with a thickness of 20 microns to 50 microns. The outer peripheral surfaces of the lower U-shaped steel belt 3 and the wear-resistant layer 4 are coated with the wear-resistant layer 4. The ceramic coating 4 has extremely high hardness and wear resistance, which can significantly improve the wear resistance of the steel belt.

[0022] The upper surface of the inverted I-shaped stainless steel belt core 1 is installed with a glass fiber braided layer 6, which has high strength and good toughness, and can increase the overall structural strength and impact resistance of the stainless steel belt core. The lower surface of the upper U-shaped steel belt 2 is installed with a copper foil protective layer 5, which has high thermal conductivity, and is helpful to dissipate the heat generated inside and maintain the temperature stability of the structure;

[0023] An alloyed galvanized belt 7 is installed on the lower surface of the inverted I-shaped stainless steel belt core 1. The alloyed galvanized belt 7 can protect the stainless steel belt core from oxidation and corrosion in a humid environment or an environment containing corrosive chemicals.

[0024] When the embodiment of the present application is in use, firstly, an upper U-shaped steel strip 2 and a lower U-shaped steel strip 3 are smelted and rolled on the upper and lower surfaces of the inverted I-shaped stainless steel strip core 1 respectively, and a wear-resistant layer 4 is arranged on the outer peripheral surfaces of the upper U-shaped steel strip 2 and the lower U-shaped steel strip 3. Compared with the rectangular cross-section, the cross-sectional shape of the inverted I-shaped stainless steel strip core 1 can provide greater bending stiffness and strength. The flange of the I-shaped cross-section can withstand greater tensile and compressive forces, thereby reducing deformation when subjected to bending force, and the structural design helps to resist distortion caused by external loads, and can distribute stress more evenly over the entire cross-section, reducing the risk of material fatigue and cracks. The upper U-shaped steel strip 2 and the lower U-shaped steel strip 3 make the inverted I-shaped stainless steel strip core 1 completely covered into a strip structure, providing additional support, reducing stress concentration in the steel strip, and thus reducing the risk of material fatigue and cracks.
