小型钢坯步进式加热炉液压传动系统

摘要   步进式加热炉用于加热小型初轧坯。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承,其外侧走轮由液压缸驱动,可在倾斜轨道上滚动,使步进梁作上升或下降运动。其内侧托轮直接托住步进梁,而步进梁则由另一液压缸带动,可在托轮上作水平前进或后退运动。通过两缸的操作,使步进梁作矩形轨迹运动,各段运动的行程可以调节,操纵方式可以连续或手动操纵。同一液压油源供双排炉床的步进梁传动,可以同时或交替动作;并可逆向运动,作为倒空炉内钢坯之用。由于作升降动作的液压缸和作水平动作的液压缸需要实现无级调速，所以采用了节流调速回路中的进口节流调速和出口节流调速。通过液压传动系统的设计，可实现上述各个动作。

Title  Walking into type transmission of hydraulic of heating furnace

of small-scale steel billet

Abstract   The type of tread into heats the stove to used for heating the small scaled and early steel .Heat a heat of bed from fix the beam and tread into the beam two parts to constitute, tread into the beam dual round is of many stalk frame pay to accept, its outside side walk the round be pressed the urn by the liquid to drive, can roll over in tilting to one side the orbit, making tread into the beam to make the rising or descend the sport.Its seamy side gives the round to give to tread into the beam directly, but tread into the beam then from another a liquid presses the urn to arouse, can make the level headway or retreat the sport in giving the round.Pass two urns operations, make tread into the beam to make the rectangle track sport, the route of travel of the each sport can regulate, manipulate the way and can continue or move to manipulate.Same liquid press the oil source to be provided for a bed of a pair of rowses to tread into the beam spreads to move, can at the same time or replace action; also contrary sport, the conduct and actions pours empty steel inside the stove. Because of making the liquid of ascend and descend the action to press the urn and make the liquid of the level action to press an urn of demand to carry out to have no the class to adjust soon, so adopted to reduce expenses to adjust soon back track in of import to reduce expenses to adjust to reduce expenses to adjust with exit soon.Press to spread the design of move the system through a liquid, can carry out the above-mentioned each action.

Keywords  the type of tread into  spread to move of hydraulic  the heated stove
