Abstract

The invention discloses online full-automatic tempering equipment and technology for a same-furnace multi-strip bimetal strip saw, and relates to tempering equipment and tempering technology. The invention solves the problems that the conventional tempering equipment and technology for the bimetal strip saw cannot finish the tempering technology on one production line at one time, the tempering technology has low production efficiency and high energy consumption and the like. The tempering equipment comprises a front rotating device, a box-type tempering furnace and a rear rotating device. The production efficiency of the saw is improved by 5 to 8 times, the energy consumption is greatly reduced, a great amount of energy is saved, the energy consumption of the box-type tempering furnace is reduced by over 60 percent compared with that of a bell-type tempering furnace or a well-type tempering furnace due to calculation, the occupancy area is reduced by over 90 percent, the problems that the bell-type tempering furnace or the well-type tempering furnace has non-uniform inner and outer temperature field and upper and lower temperature field, the bending stress of the saw is non-uniform, and the saw is easily upwarped are solved, repeated rewinding processes needed by the box-type tempering furnace or the well-type tempering furnace are canceled, and the problem of difficulty in controlling the saw tempering technology and quality and the problem of difficulty in maintaining the equipment are solved.

Description

technical field [0001] The invention relates to heat treatment and tempering equipment and technology for producing bimetal band saw blade products. Background technique [0002] The most important process in the production of bimetallic band saw blades is heat treatment, which includes quenching and tempering. At present, bell-type furnaces or well-type furnaces are used at home and abroad to statically temper the saw blades for three times, and each tank needs more than 30 hours to complete. Repeated heating and cooling are required many times, and rewinding in forward and reverse directions is required, which consumes a lot of manpower and material resources. Therefore, the existing tempering equipment technology has the following problems: first, the equipment capacity is too low, the energy consumption is large, and the production cost is high. For example, a 60 kilowatt bell-type tempering furnace has a single-shift production capacity of only 2,000 meters, which con...
