Problems solved by technology
[0002] Pipe annealing needs to go through several steps such as preheating, heating, and cooling. In the existing annealing furnace equipment, the preheating zone, heating zone, and cooling zone are not independent. When the fan is turned on in the cooling zone to cool the pipe, the annealing furnace The temperature of each section in the heating zone will drop, and when the furnace door of the heating zone is opened, the temperature in the heating zone will be lost to a certain extent.

Description
【Technical field】 [0001] The invention relates to the field of pipe material processing equipment, in particular to a chain annealing furnace and a pipe material transmission control method. 【Background technique】 [0002] Pipe annealing needs to go through several steps such as preheating, heating, and cooling. In the existing annealing furnace equipment, the preheating zone, heating zone, and cooling zone are not independent. When the fan is turned on in the cooling zone to cool the pipe, the annealing furnace The temperature in each section of the furnace will drop, and when the furnace door of the heating zone is opened, the temperature in the heating zone will be lost to a certain extent. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and propose a chain annealing furnace. The transmission speeds of pipes in different areas in the annealing furnace are different, which reduce...
