Abstract

The invention discloses a high-thermal-conductivity and high-temperature-resistance pan material for zinc-aluminum alloy hot dip coating and a machining process of the high-thermal-conductivity and high-temperature-resistance pan material. The high-thermal-conductivity and high-temperature-resistance pan material comprises, by weight, 1.2-1.5% of Li, 0.2-0.4% of Ti, 0.3-0.5% of Ba, 9.0-10.5% of Cr, 5.0-8.0% of Ni, 2.0-4.0% of Mn, 2.0-3.0% of Sn, 0.2-0.4% of B, and the balance Fe. The development and industrialization of the material provides a solution of material science for solving the current problems that existing iron pans are too short in service life and inconvenient to replace and mount in hot dip coating zinc-aluminum alloy production. The implementation and industrialization of the material is of great importance in solving the current industry status in China and improving the product international competitiveness of the metallurgical industry in China.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a zinc alloy. Background technique [0002] The ocean covers about 71% of the earth's surface, and the marine industry has become an important pillar of the world's economic development. The salt concentration in seawater is high, oxygen-rich, and there are a large number of marine microorganisms and macrobiotics. Coupled with the impact of waves and sunlight, the marine corrosion environment is relatively harsh. Corrosion in the marine environment has become the most important factor affecting the safety, service life and reliability of facilities, and has attracted great attention from governments and industries around the world. [0003] After the steel is galvanized, the corrosion resistance is greatly improved, which can save materials and resources, and exert better economic and environmental benefits. During the use of steel, the coating is partially damaged, and the expo...
