180吨转炉倾动机构设计

摘要

在转炉设备中的倾动机械是实现转炉炼钢生产的关键设备之一，炉体的工作对象是高温的液体金属，在兑铁水、出钢等项操作时，要求炉体能平稳地倾动和准确的停位。为获得如此低的转速，需要很大的减速比。转炉炉体自重很大，再加装料重量等，整个被倾转部分的重员要达上百吨或上千吨本设计说明书以鞍钢180吨转炉全悬挂倾动装置为借鉴，以倾动角度连续回转360度，倾动速度范围从0.1r/min~1.0r/min进行设计。主要内容包括：分别对转炉的空炉，炉液的重心进行计算；转炉倾动力矩的计算；电机的确定和传动比的分配；倾动机械及其传动件的设计（包括传动方案的选择，根据倾动力矩进行电动机的选择和校核，减速器的设计，主要零部件的强度校核）；抗扭缓冲装置的设计，此外，还进行了技术经济性分析。

180 Tons Of Converter Titled Holding Mechanism

Design

ABSTRACT

In converter equipment is to realize the titled holding machinery converter steelmaking production of one of the key equipment, furnace work object is the temperature of the liquid metal, confirmed the steel in metal, and wait for an operation, requirements can smoothly titled holding furnace and accurate stagnate. To obtain such a low speed, need a great deal of the deceleration than. The converter furnace self-respect is very big, install additional material weight, the whole is turned out of the part of the heavy member to reach over tons or thousands of tons of this design specifications in angang 180 tons of converter for reference for the suspension titled holding device, titled holding Angle continuous rotary 360 degrees, titled holding speed range from 0.1 r/min ~ 1.0 r/min to carry on the design. The main contents include: to the empty respectively of converter furnace, the furnace calculated the center of gravity of the fluid; The calculation of torque converter titled holding; Determination of the motor and the transmission ratio of the distribution; and Titled holding machinery and transmission parts design (including transmission scheme choice, according to the choice of the motor torque of titled holding and check, the design of the speed reducer, the main components of stress test); The design of the buffer device to wrest resistant, in addition, also carried out technology economy analysis.

Key: The converter; Steelmaking institutions;;Titled holding machinery; Titled holding device.
