Problem Description During shield machine excavation, viene utilizzata la macchina a vite. Le lame vengono ruotate all'interno del contenitore del terreno. Di conseguenza, le scorie all'interno del contenitore provocano una continua usura delle lame. Sulla parte esposta del contenitore terriccio è necessario applicare un trattamento antiusura. Quando le scorie entrano nella canna della macchina a vite, cambia...
High manganese steels are used because of their excellent wear resistance and toughness.Two popular types are Mn13 and X120Mn12.In this guide, i punti chiave, usi, e le differenze verranno spiegate semplicemente. Overview of Mn13 and X120Mn12 Both steels are known for high strength and resistance to wear.They share similar compositions but are...
Wear-Resistant Steel Plates Overview Wear-resistant steel plates are used where heavy wear and damage often occur. These plates are made with a strong base and a durable surface layer. Composition and Structure Wear-resistant plates are made from two layers: Strato di base (Piastra in acciaio laminato a freddo):Used for strength and bending resistance. Surface Layer (Aluminum Alloy):Provides high wear resistance. 🔹...
1. Basic Concepts Both high manganese steel and manganese steel are special types of steel. They contain high levels of manganese and are known for their pressure resistance and wear resistance. Manganese steel usually contains 11%–14% manganese. High manganese steel contains more than 14%, often up to 18% or more. 2. Key...
Quali sono i materiali per tubi resistenti all'usura e come sceglierli? I tubi vengono spesso utilizzati per trasportare materiali nei sistemi industriali. They are like the blood vessels of factories. Tuttavia, because materials flow through them, pipe walls can wear down over time. To prevent this, wear-resistant pipes are needed. Different types of wear-resistant...
Alloy Composition The wear-resistant layer is made from a high-chromium alloy.Its composition includes: Carbonio (C): Di 5.0% Cromo (Cr): 27–30% A martensitic base with a high volume of Cr₇C₃ carbides, making up over 60% of the structure. Hardness Alloy layer hardness: HRC 57–65 Carbide hardness: HV 1400–1800 These values ensure high resistance to...
Introduction High-strength wear-resistant steel is created by adding alloying elements that enhance the material's structure through solid solution strengthening, rafforzamento dei bordi di grano, e rafforzamento della seconda fase. Questo tipo di acciaio include l'acciaio martensitico a bassa lega, acciaio bainitico, e acciaio bifase. Composition and Properties Recent advancements use silicon as the main alloying element, leveraging its ability...
Resistente all'abrasione (AR) la piastra in acciaio è un acciaio legato ad alto tenore di carbonio progettato per una maggiore durezza rispetto all'acciaio a basso tenore di carbonio. This increased hardness makes AR steel ideal for harsh, high-abrasion conditions but unsuitable for structural applications. Key Characteristics Unlike many structural steels, AR steel is not governed by ASTM codes or specific chemical compositions,...
