Abstract

The invention discloses a multifunctional one-furnace multi-strip quick high-efficiency heat treatment production line and a process for bimetal strip saw blades, and relates to a heat treatment production line and a quenching process for bimetal strip saw blades. By the production line and the process, a technology for heating and cooling the saw blades quickly is implemented, the saw blades have high quality, and high efficiency, high capacity, low input, low cost and low energy consumption are achieved. Quick step quenching is performed by a deep cooling, water cooling, air cooling and nitrogen composite cooling process, so that the high efficiency and high capacity of production and the high quality of the saw blades can be ensured; and all process equipment is integrated into one production line, all processes such as quenching, tempering, sand blasting, cleaning, drying, marking, oiling, straightening and the like are finished on one production line, and a plurality of band saw blades of various specifications can be produced on one production line simultaneously. After the production line is implemented, the capacity of the saw blades is improved by about 3 times, the quality of products is improved by about 30 percent, energy such as electricity, water, oil, gas and the like is saved by over 200 percent, project investment is saved by over 200 percent, plant and land are saved by over 150 percent, production cost is reduced by over 50 percent, and the contradiction and technical bottleneck problem of conventionally exchanging quality for yield and exchanging high input for high capacity for years are radically solved.

Description
