Embodiment Construction

[0024] For better understanding of the present invention, below in conjunction with specific embodiment is further described:

[0025] 1. Chemical composition design of high-temperature wear-resistant kiln mouth guard iron:

[0026] Chemical composition is the key factor determining the performance of alloys. To solve the problem of metal wear resistance under high temperature conditions, a reasonable composition design must be carried out first. Through comprehensive comparison and analysis, the present invention is determined to be based on chromium and nickel alloys, and adopts the combination of dominant alloying factors (chromium, nickel) and auxiliary elements (nitrogen, titanium, niobium, tungsten, rare earth) to form alloy materials. One is to obtain the austenite matrix, and the other is to form MC carbide and reduce M 23 C 6 Type compounds to ensure the oxidation resistance, creep resistance and wear resistance of alloy materials at high temperatures.

Abstract

The invention discloses a high-temperature wear-resistant kilneye protection iron alloy using the chromium-nickel alloy as the essential element. The kilneye protection iron alloy comprises the following components by weight percentage: C of 0.25-0.60, Cr of 26.00-30.00, Ni of 9.00- 12.00, Si of 0.80-1.50, Mn of 1.00-2.00, N of 0.15-0.30, Mo of 0.20-0.50, W of 0.50-1.00, Ti of 0.20-0.60, Nb of 0.20-0.60, V of 0.20-0.50, Re of 0.20-0.50, S<=0.04, P<=0.05, and Fe of the rest.The manufacturing process of the high-temperature wear-resistant kilneye protection iron alloy comprises steps of moulding preparation, smelting and pouring and thermal treatment. The invention solves the problem that the existing kilneye protection iron is un-wearable under a high temperature and the produced high-temperature wear-resistant kilneye protection iron alloy has three main advantages of high stretching and rigidity specific elongation index at normal temperature, strong oxidation resistance and antiwearquality at high temperature and service life longer than that of the existing products.

Description

Technical field: [0001] The invention relates to a high-temperature wear-resistant alloy material, in particular to a high-temperature wear-resistant kiln mouth sheath iron alloy and a production method thereof. Background technique: [0002] Most of the key equipment in basic industries such as metallurgy, chemical industry, electric power, and building materials operate at high temperatures, and the heat-bearing parts are often located at the core of high-temperature equipment. The quality of the heat-bearing parts directly affects the entire equipment. normal operation. For example, the kiln guard iron, the key component of the rotary kiln for slag roasting in the alumina industry, is located at the discharge end of the rotary kiln, which protects the inner lining of the rotary kiln and is also the connection between the rotary kiln shell and the external parts. body. When the rotary kiln is working, the magma-like alumina firing material above 1150°C, due to the rotati...
