[0036] Refer to Figure 2 And Figure 3The drying device 3 comprises a drying cover plate 31 and a drying kiln body 32. The upper end of the drying kiln body 32 is open. The drying kiln body 32 is divided into a drying inner kiln 321 and a drying outer kiln 322. The heat preservation pipeline 34 is S-shaped. The heat preservation pipeline 34 is fixedly installed on the four peripheral side walls of the drying inner kiln 321 towards the drying outer kiln 322 through a plurality of pipeline clamps 35. Four support blocks 323 for supporting the drying cover plate 31 are installed on the end face of the opening of the drying outer kiln 322 at intervals, so that a transmission channel 33 for the round steel 6 to pass through is formed between the drying cover plate 31 and the drying kiln body 32.
