Production technology for smelting and cladding alloy reinforced wear-resisting sliding plate

Abstract

The invention relates to a smelting and cladding alloy reinforced wear-resisting sliding plate, sliding block and lining plate in the industries, such as metallurgical equipment, mining equipment, mine equipment, petroleum drilling machine equipment and the like. The production technology for the smelting and cladding alloy reinforced wear-resisting sliding plate, sliding block and lining plate comprises the following steps of: 1) carrying out torch cutting and baiting to the matrix steel plate of the sliding plate, and cleaning torch cutting residues; 2) tempering and processing the matrix; 3) roughly processing the matrix; 4) carrying out stress relief annealing; 5) roughly grinding a matrix working plane, and cleaning surface greasy dirt; 6) smelting and cladding the working plane; 7) carrying out high-temperature tempering; 8) correcting; 9) carrying out machining; 10) carrying out stress relief annealing; and 11) roughly and finely grinding a smelting and cladding layer to obtain the smelting and cladding alloy reinforced wear-resisting sliding plate. The smelting and cladding alloy reinforced wear-resisting sliding plate disclosed by the invention has the advantages of good wear resistance, no delamination, good toughness and small possibility of deforming, the hardness can be above 55HRC, a hardness layer is eternally combined with the matrix, the product can be repaired and used, and the material cost can be greatly lowered.

Description

technical field [0001] The present invention relates to metallurgical equipment, mining equipment, mining equipment, oil drilling rig equipment and other industries of heavy-duty sliding pair wear-resistant parts, especially refers to cladding alloy strengthened wear-resistant slide plates, sliders, liners, such as rolls used in the metallurgical industry, Conveyor rollers, guide plates, pinch rollers, etc. Background technique [0002] Rolling mill slides, sliders, and liners play a key role in the precision of the rolling mill, and the precision of the rolling mill and the clearance control of the slide pair play a decisive role in the product quality. Therefore, the selection of the sliding plate of the rolling mill plays a vital role in the product quality of the steel rolling enterprise. [0003] At present, there are two types of slide plates, sliders, and liners used in domestic rolling mills (for the convenience of description, "slides" are used, and "slide plates, ...

However, the disadvantages of this skateboard are as follows: 1. During the use of this kind of skateboard, the bottom layer and the use layer (wear-resistant layer) must not only resist the alternating fatigue stress of cold and heat, but also resist the corrosion and cavitation of cooling circulating water The influence of the impact makes the skateboard peel off and delaminate earlier. Once delaminated, the skateboard will be di
