Steel tempering equipment

The invention discloses steel tempering equipment. The steel tempering equipment is characterized by comprising a machine body housing, a reaction furnace, a rotary main shaft, connection shafts, a support frame and a power motor, wherein the reaction furnace is arranged in the machine body housing; the rotary main shaft is arranged at the center in the reaction furnace; the connection shafts arearranged at the two ends of the rotary main shaft; the support frame is arranged at ends away from the rotary main shaft, of the connection shafts; the power motor is arranged in the support frame; and the power motor is connected with the connection shafts. Compared with the prior art, the steel tempering equipment is reasonable in structure; through arrangement for a console, a temperature in the reaction furnace can be automatically controlled; and a cooling liquid enters the rotary main shaft through the connection shafts, and then is uniformly injected from holes in the rotary main hole,so that the technical problems of low efficiency caused due to the need of manual detection control in temperature control, low steel quality caused due to non-uniform adding for the cooling liquid, in a steel tempering process in the prior art, are solved.
