机械毕业设计403步进式加热炉同步顶升液压控制系统说明书

摘要

加热炉是将物料或者工件加热的设备。在冶金工业中加热炉习惯上指把金属加热到轧制成锻造温度的工业炉。步进梁式再加热炉是连轧生产线提供钢管再加热所有。它是依靠专用的步进机械使工件在炉内移动的一种机械化炉子。

步进梁式加热炉设计一种连续式加热炉它是靠专用的步进机构，按照一定的轨迹运动，使炉内钢料一步一步地向前推进。

步进梁式加热炉炉底的结构和传动方式要根据出料的频率和炉子的生产能力决定，它要考虑被加工工件的尺寸参数和工地方面的尺寸大小。所以必须严格计算其内部参数，保证炉子的生产和安全。

炉底机械采用双轮斜轨机构。步进梁的升降和平移动作采用液压缸驱动。加热炉炉床由固定梁和步进梁两部分组成，步进梁由双重轮对的多轴框架支撑，其外侧走轮由液压缸驱动，可以在倾斜轨道上滚动，使步进梁作上升或者下降运动。上层托轮直接拖住步进梁，而步进梁则由另两个液压缸带动，实现平移运动。

Abstract

Heating furnace is the material or workpiece heating equipment. In the metallurgical industry in the metal to heating habits heated to rolled into the industrial furnace temperature forging. Walking beam type furnace is provided to steel rolling line heating all again. It depend on special stepping machinery to make the work in the furnace stove a mechanized moving.

Stepping beam furnace design a continuous reheating furnace of it is to rely on special stepping institutions, according to certain trajectory, making furnace of steel material within step forward.

Step reheating furnace bottom structure and driving mode according to the material of the frequency and the production capacity of the stove, it should consider decision by the size of the machining parameters and the site of size. So must strictly calculation its internal parameters, guarantee the production and the stove safety.

Furnace bottom machine adopts double inclined rail agencies. The rise and fall of walking beam by hydraulic cylinder for peace movement driven. Heating furnace bed by fixed girders and walking beam two parts, walking beam of by double round multiaxial framework, the lateral go round supported by hydraulic cylinder drive, can tilt orbit in rolling make walking beam rise or fall as sport. The upper roller direct tugged walking beam, and walking beam is driven by two other hydraulic cylinder, realize the shift movement.

KeyWords：stepping beam furnace，walking beam，double inclined rail mon rail agencies，hydraulic transmission
