Walking beam furnace

Abstract

The invention discloses a walking beam furnace. The walking beam furnace comprises a furnace body, a conveying device and a heating device; the conveying device at least comprises a conveying table, a horizontal moving mechanism moving the conveying table in the horizontal direction and a lifting mechanism lifting the conveying table in the vertical direction, wherein the horizontal moving mechanism is connected under the conveying table and is movably connected to the lifting mechanism in a linear mode in the horizontal direction; and supporting tables are arranged in the furnace body and are arranged on two sides of the conveying table in parallel. According to the walking beam furnace, the conveying device is matched with a supporting structure in the furnace body to transfer steel pipes in a circulation mode of lifting, horizontal moving and laying down.

[0002] The heating furnace plays a very important role in the production of steel pipes. The structure of the traditional steel pipe heating furnace is an ordinary inclined bottom furnace. Overheating furnace, so that the process of heating steel pipes can be completed in a streamlined manner during the transportation of steel pipes, but in the actual production process of steel pipes, the steel pipes in the heating furnace need to be fully heated, which requires preheating and reheating steps. The speed of conveying in the heating furnace for a single steel pipe to complete this step is generally lower than the normal conveying track, so it is easy to transport confusion here, resulting in inconsistent gaps and quantities of steel pipes in the heating furnace, which ultimately affects the overall quality. Heating efficiency has a great influence on the quality of steel pipe after forming

[0003] The existing technology uses conveying tracks with different conveying speeds to pass through the steel pipes, and uses a manual pipe pulling device to move the steel pipes from the normal conveying track to the conveying track of the heating furnace. The distance between the steel pipes, and the steel pipes entering the heating furnace in this state are prone to surface adhesion and other quality problems under the action of heating, and the labor intensity is high
