Novel abrasion resistant steel plate and production method thereof

Abstract

The invention discloses a novel abrasion resistant steel plate and a production method thereof. The novel abrasion resistant steel plate comprises the following components by weight percent: 0.03-0.20% of C, 0.20-0.40% of Si, 3.5-6.0% of Mn, 0.010% or less of P, 0.005% or less of S, 0.002-0.020% of Ti, 0.20% or less of Mo and 0.055% or less of Al, with the balance being Fe and impurities. The technology comprises the steps of smelting process, continuous casting process, heating process, rolling and heat treatment process. The novel abrasion resistant steel plate and the production method thereof have the advantages that through the smooth implementation of the five key processes of manganese alloy melting during the smelting process, continuous casting, billet steel hot delivery, steel plate hot rolling and heat treatment, the produced abrasion resistant steel plate is high in low-temperature toughness and hardness, good in abrasion resistance and long in service life.

Description

technical field [0001] The invention relates to a novel wear-resistant steel plate and a production method thereof, belonging to the technical field of iron and steel manufacturing. Background technique [0002] According to the applicant's understanding, there are three main damage forms of materials "that is, fracture, abrasion and wear. Although wear is not like the other two forms, it rarely causes catastrophic damage to metal workpieces, but the economic losses it causes are quite staggering. Foreign statistics It shows that friction consumes 1 / 3 of the primary energy in the world, about 80% of the machine parts fail due to wear, and about 50% of the catastrophic accidents of mechanical equipment are due to lubrication failure and excessive wear. At present, the country's energy gap is getting bigger and bigger, and the role of the equipment manufacturing industry in the national economy is getting stronger and stronger, so it is of great significance to speed up the re...

Problems solved by technology

[0003] At present, the production process of martensitic wear-resistant steel at home and abroad is relatively complicated, and the process control is relatively difficult. Not only does it need to use quenching and tempering treatment to obtain uniform wear resistance, but also needs to add precious metal elements such as Ni and Mo to improve the toughness and resistance of steel.

my country has researched and developed high-quality wear-resistant steel in recent years, but there is still a significant gap between the overall level and foreign countries
