Oil drum waste heat utilization heating device capable of guaranteeing uniformity of oil film on surface of steel plate

Abstract

The invention relates to an oil drum waste heat utilization heating device capable of guaranteeing the uniformity of an oil film on the surface of a steel plate. The oil drum waste heat utilization heating device comprises a spiral heat radiation pipe, a vertical column, a rotating mechanism, a lifting mechanism and an oil drum clamping mechanism; the spiral heat radiation pipe is arranged in a pit, the vertical column is arranged on the position, on one side of the pit, of the ground, the rotating mechanism is arranged on the upper part of the vertical column, the lifting mechanism is arranged on the rotating mechanism, and the oil drum clamping mechanism is arranged at the bottom of the lifting mechanism and used for clamping an oil drum; and the spiral heat radiation pipe is located below a moving path of the oil drum, the inner diameter of the spiral heat radiation pipe is larger than the outer diameter of the oil drum, and the height of the spiral heat radiation pipe is larger than that of the oil drum. As for drum anti-rust oil before being added into an oil tank of an oiling machine, the device can heat the oil drum and the anti-rust oil together, thus a thixotropic agent playing a key role in the stability of the steel plate oil film is fully dissolved into oil liquid, and the problems that as for the hot-dip galvanized steel plate, a steel coil leaks the oil, anti-rustcapability is lowered, and production continuity is affected due to the uneven oil film are effectively solved.

Description

technical field [0001] The invention relates to the technical field of production of hot-dip galvanized steel sheets for automobiles, in particular to a heating device for utilizing the waste heat of an oil drum to ensure the uniformity of the oil film on the surface of the steel sheet. Background technique [0002] In the production process of hot-dip galvanized steel sheets for automobiles, the surface of the steel sheets will be coated with a layer of anti-rust oil, and the uniformity of the oil film of the applied anti-rust oil will affect the follow-up links such as preventing oil leakage of steel coils, storing anti-rust, and ensuring smooth stamping production. Therefore, how to ensure that the oil film on the surface of the hot-dip galvanized steel sheet is in a uniform state is particularly important for the production of hot-dip galvanized steel sheets for automobiles. [0003] In order to ensure the uniformity of the oil film on the surface of the hot-dip galvaniz...
