The Designing Of Medium Plate 2800 Hot Straightening Main Drive System

Abstract

Rolling production has become the metallurgical industry in the production of steel billets made important production processes, with the yield, variety, is the degree of mechanization and automation of many of the advantages of higher domestic production process, it is an important technology to meet the national production needs. The design of the leveler was 11 roll straightener main drive system. The first step in analyzing the straightening technology development status at home and abroad, analyzes the use classification, and the different types of leveler straightening machine; the second step, a detailed comparison of the advantages and disadvantages between the two programs, select the the main transmission system optimal solution, and were selecting the motor, reducer, gear housing, couplings and other components; the third step, identified a number of basic parameters and power leveler energy parameters, such as: basic parameter determines the roll diameter, roll away, roll number, roll speed and roll body length, force and energy parameters determined its Straightening and straightening moment; the fourth step, conducted a roller bearing areas such as the strength of the school does not feed ah Collar nuclear determine choice involved and not into the ah safety performance and whether it meets the requirements; Finally, the selection of lubrication, the economic feasibility analysis, environmental analysis and so on.
