Push-rod furnace vertical material distribution machining method for ingot blanks

Abstract

The invention belongs to an ingot blank machining method and adopts a push-rod furnace vertical material distribution machining method for ingot blanks. A push-rod furnace is provided with a hydraulic feeding push rod 1, a push-rod furnace feeding port furnace door 3, a furnace body 4, a smoke exhaust flue pipe 5, a push-rod discharging port furnace door 6 and material pad track grooves 9. The two material pad track grooves 9 are arranged parallelly, material pads 8 are arranged in the material pad track grooves 9, and cuboid-shaped copper ingot blanks 7 are arranged on the material pads 8 vertically. By means of the machining method, contact area between the copper ingot blanks and the material pads is reduced, effects of material pad impurities on the surfaces of the material pads are reduced, charge amount of the furnace is also increased, and production efficiency is improved.

Description

technical field [0001] The invention belongs to a method for processing an ingot, in particular to a method for distributing materials for an ingot in a pusher furnace. Background technique [0002] Ingot pusher furnace is a heating furnace that uses natural gas to heat copper ingots through burners. The feeding method is to send ingots into the furnace through push rods. There are two parallel U-shaped rails installed at the bottom of the push rod furnace, and there are pads placed in the rails. The pads are section by section, and the pads in the two rails correspond one by one. On the corresponding material pads, a pair of material pads places an ingot. When feeding, the hydraulic cylinder drives two round rods to push the mats to slide in the track, and the mats in the furnace are pushed against each other from the direction of the furnace entrance to the direction of the furnace exit, thus completing the furnace feeding. [0003] The mats used in pusher furnaces curre...

AI Technical Summary

Problems solved by technology

[0003] The mats used in pusher furnaces currently on the market are rectangular (such as image 3 ), the running resistance of the material pad in the track is relatively large, and it is easy to cause the material pad to arch and cause the material pad to derail, which in turn causes the furnace to be stuck. The solution is to stop the furnace for treatment, resulting in energy waste

[0004] The ingot is placed flat on the rectangular material pad. Since the material pad is easy to absorb and accumulate impurities during the heating and cooling process, the material pad containing impurities on the surface enters the pusher furnace again during use. After reheating, the raised impurities are easy to damage the surface of the ingot. produce an effect that causes product flaws, defects
