The utility model provides a contact type driving roller bar and roller bottom type heat treatment equipment, and relates to the technical field of heat treatment, the contact type driving roller barcomprises a bearing roller bar structure and at least one transmission shaft, at least one end of the bearing roller bar structure is provided with an expansion guide groove, and the transmission shaft is assembled in the expansion guide groove at intervals. And a connecting piece is arranged on the transmission shaft and is clamped in the expansion guide groove, so that the transmission shaft andthe bearing roller rod structure are kept relatively fixed. Compared with the prior art, the contact type driving roller rod has the advantages that the original integrated roller rod is replaced bythe split type bearing roller rod structure and the transmission shaft, and is fixed through the connecting piece, so that the overall heat conduction efficiency of the roller rod can be greatly reduced, heat is prevented from
