Description
Technical Field
The invention belongs to the technical field of welding wires, and particularly relates to a ceramic particle welding wire for a roller surface of a roller press and a preparation method thereof.
Background
At present, abrasion, corrosion and fracture are three modes of failure of metal materials, and the economic loss caused by abrasion is the most serious. For example, ceramic rolls, which are grinding members of vertical roller mills, have considerable wear resistance and are widely used in cement production and thermal power plants for the production of raw materials, coal, and clinker. However, some ceramic rollers fail prematurely due to the presence of irregular material or excessive wear, resulting in surface spalling and cracking, resulting in breakage of portions of critical areas before the end of life expectancy, resulting in reduced productivity and even downtime. The existing solution is to order imported new ceramic rolls for replacement, but the lead time plus installation down time takes 3-6 months. Therefore, to avoid the huge economic losses associated with downtime, it is imperative that the weld overlay repair be performed before the new roll arrives. The wear-resistant surfacing welding is an economic and rapid process method for modifying the surface of a material, can effectively change the wear resistance, corrosion resistance and other mechanical properties of the surface of the material, has obvious effects of prolonging the service life of parts, reasonably using the material, improving the product performance and reducing the cost, and is more and more widely applied to the manufacturing and repairing of mechanical parts. Especially for the work piece that high abrasion resistance, high temperature corrosion resistance nature environment required under extreme operating mode, especially important. The more commonly used flux-cored wires E501T-1(E71T-1) all belong to titanium flux-cored wires, and the powder of the flux-cored wires is mainly acidic oxides and reaches the balance of oxidation and reduction with deoxidizers in the powder in molten pool reaction. The ceramic liner is mainly composed of silicon dioxide and aluminum oxide. When the ceramic liner is used together with a flux-cored wire, electric arcs directly act on the ceramic liner during first backing welding, and silicon dioxide and aluminum oxide in the ceramic liner enter a molten pool to react, so that oxides in the molten pool are increased, the balance of redox reaction is broken, and inclusions in deposited metal are increased. The plasticity and the toughness of the welding seam are reduced, and the crack tendency is increased.
