Domestic bearing steel rolling new technology
(1) single austenite region of rolling process control; finishing rolling in austenite single phase region. For the rolling process of the most basic, after rolling product performance in general, all need to do post heat treatment.
(2) austenite and austenite and carbide two area of hot rolling process;
In control rolled austenite and ferrite co existing Ar3 ~ Ar1 temperature range. In the two-phase region of controlled rolling and the aim is to obtain more micro organization, in order to ensure the low temperature toughness does not reduce or slightly decreased under the premise, so that the strength of steel, especially yield strength greatly increased
(3) the production process of hot rolling and online spheroidizing annealing combination;
Refers to the rolling process of hot billet directly spheroidizing annealing in single-phase or two-phase region rolling zone after. Using this process after rolling of Yu Wen finished with appropriate cooling process directly, can get good performance, and can save energy, increase production efficiency.
(4) low temperature heating and rolling process;
Low temperature rolling is lower than that of the conventional billet heating to the heating temperature, rolling in lower than that of the conventional hot rolling temperature, more specifically is medium temperature rolling, the main purpose is to reduce the billet heating required energy consumption, reduce metal loss, reduce the roll consumption, improve the surface quality, product grain refinement, so as to improve the performance of the products, can be instead of process de heat treatment parts products.
