A known method of increasing the durability of elements exposed to intense abrasion is the use of alloyed steel, cast steel or cast iron. The disadvantage of this method is the high cost due to the use of expensive materials and the need to heat-treat the elements. Another method is to surfac the surfaces of the objects subject to abrasive wear through the use of coated electrodes. The most commonly used manual surfacing with coated electrodes is technically and economically unprofitable due to the high laboriousness of the process and the low quality of welds. self-shielding wires. In the development of these wires, the essential criterion for assessing their suitability is the achieved durability of the padding weld, taking into account the costs. This aim was achieved by selecting the appropriate chemical composition for the self-shielding strand wire. The alloy of self-shielding stranded wire consists of: carbon in an amount from 2.6% to 3%, chromium in an amount from 20% to 22 %, manganese from 1.7% to%, silicon from 1.4% to 1.7%, titanium from 0.1% to 0.5%, the rest iron. limestone dust containing SiO 2, Fe 2 O 3, CaCO 3, MgCO 3, Al 2 O a and others in an amount from 8% to 15% by weight of the core is added to the core mixture. Gradually made with the self-shielding flux-cored wire, which is the subject of the invention, it may have the chemical composition as in the examples given. 1.7%, silicon 1.4%, titanium 0.1%, the rest iron. Lime dust containing SiO 2, Fe 2 O 3, CaCO 3, MgCO 8, Al 2 O 3 and others is added to the core mixture in an amount from 8% to 15% by weight of the core. Example II. The flux cored weld metal consists of 3% carbon, 22% chromium, 2% manganese, 1.7% silicon, 0.5% titanium, the rest iron. Lime dust, containing SiO2, Fe2O3, CaCO3l, MgCO3, A12C8 and others in an amount from 8% to 15% by weight of the core, is added to the core mixture. hard carbon phase, consisting of chromium carbides, which provides it with high abrasion resistance and a hardness of 50 HRC. intense abrasion with low impact loads. This wire is especially suitable for surfacing various types of anti-abrasive linings, chutes, elbows, etc. The use of the wire according to the invention increases the durability of elements, and thus extends the periods between assembly works of machines and devices. surfacing, characterized in that the weld metal contains from 2.6% to 3% carbon, from 20% to 22% chromium, from 1.7% to 2% manganese, from 1.4% to 1.7%. % silicon, from 0.1% to 0.5% titanium, the rest is iron. 2. Flux cored wire according to claim The process of claim 1, characterized in that lime dust is added to the core mixture in an amount of 8% to 15%. 5 10 ZGK 679/1110/84 - 95 copies Price PLN 100, - PL PL
