Description

Technical Field

[0001] The utility model relates to the technical field of heating production, in particular to a heating furnace. Background Technique

[0002] In the metallurgical industry, a heating furnace is a device (industrial furnace) that heats materials or workpieces (usually metals) to the rolling or forging temperature. Heating furnaces are widely used in many industrial fields such as petroleum, chemical industry, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, and pharmaceuticals. In the production process of high-speed wire laying pipes, a heating furnace is usually used. When using this heating furnace, the billet is conveyed to the inlet of the heating furnace through a roller table, and then the billet is fed from the inlet into the furnace body of the heating furnace through a lifting and feeding assembly. A continuous heating furnace that moves the billet forward step by step by the rising, advancing, descending, and retreating movements of the water-cooled metal beams in the furnace. After heating, the billet is lifted out from the outlet of the furnace body through the lifting and feeding assembly, and then placed on the roller table on the other side to transfer the heated billet to the next processing step.
