Description
Technical field
The present invention relates to high temperature work-piece cools residual neat recovering system, particularly one casting, forging high efficiency cooling bootstrap system.
Background technology
Announce and implement 2008 " Energy Conservation Law of the People's Republic of China ", country just constantly promotes enterprise and reduces output value energy consumption and energy consumption of unit product, eliminate highly energy-consuming production technology and equipment, encourage, help the power-saving technologies such as industrial enterprise's UTILIZATION OF VESIDUAL HEAT IN, accelerate the mode of production and the consumption mode that form energy-conserving and environment-protective, strengthen the capability of sustainable development.The technique that cools before iron and steel, machinery production industry must carry out workpiece transport after producing steel ingot, casting, forger part or before next procedure production, will a large amount of heat energy of release in the process that cools, to be directly discharged in environment and not only to cause energy waste but also to causing environmental pollution.
In production, foundry goods after being cast, before knockout, all needs certain cool time, after casting solidification, and can knockout.Cool too fast foundry goods easily to crack, therefore the cooling velocity of foundry goods must meet the requirement of process for cooling.But in order to enhance productivity, accelerate place and sandbox turnover, cool time must be shortened again, so controlled very important to cool time as far as possible.The iron casting workshop of mechanical production line, the casting mold after cast is in the process of mould conveyer conveying, realize gravity-flow ventilation cooling.Forging cooling is requisite operation in Forging Technology process, because cooling after forged is improper in production, often makes forging warpage, and case hardness raises, and even cracks.For ensureing forging quality, often the forging after forging is put in atmosphere cooling naturally, the method cooling velocity is uncontrollable, easily causes workpiece quality problem, and cooling residual heat to be all discharged in environment and not only to cause energy waste but also contaminated environment.Or the forging after forging is imbedded filling in the melt pit of the less sand of thermal conductivity, slag, lime or asbestos carry out cooling also known as hole cold, but this method cooling velocity is slower, usually the medium-sized forging of medium carbon steel, alloy tool steel and most of low-alloy steel is only applicable to, and carbon, C steel forgings is cheated cold again after needing first air cooling to 700 DEG C-650 DEG C, and heat still all wastes.Put into the heating furnace of 500 DEG C one 700 DEG C again or by the forging after forging immediately, with stove cooling (claiming: stove is cold), this is one cooling means the most slowly, be suitable for the large forgings of medium carbon steel and low-alloy steel and the strength member of high-alloy steel, though energy controlled cooling model speed, but heat is not still recycled, but also occupy the service efficiency of heating furnace.
Summary of the invention
The present invention is directed to existing production procedure and technology Problems existing, a kind of casting, forging high efficiency cooling bootstrap system are provided, be intended to the cooling velocity of cooling velocity requirement conservative control foundry goods by different workpieces or forging, avoid cracking at inside workpiece because work-piece cools speed is uncontrollable, be out of shape or the defect such as warpage, and by effective for work-piece cools waste heat recycling, improve the recycling rate of resource, reduce environmental pollution.
