Packaging method of wide cold-rolling stainless steel coil

Abstract

The invention relates to a packaging method of a wide cold-rolling stainless steel coil, aiming at improving the packaging quality of the wide stainless steel coil. The packaging method comprises the following steps: selecting an inner paper angle protector and an outer paper angle protector according to the size of the inner diameter and the outer diameter of the coil; respectively wrapping one circle of paper angle protector on the inner ring and the outer ring of the coil; filling a cardboard tube in an inner core of the coil; selecting a packaging plastic cloth cover according to the size of the outer diameter of the coil, completely wrapping the coil with wire-adding film-laminating compound paper; wrapping an inner protection board and then wrapping an outer inner protection board; wrapping an inner protection angle and an outer protection angle and protection boards at two side ends, wherein the inner protection angle and the outer protection angle are made of cold-rolling galvanized plates, and according to the coil weight, the quantity of coil core-passing belts is 5-6 when the coil weight is more than 5t, and the quantity of coil core-passing belts is 3-4 when the coil weight is less than or equal to 5t; and wrapping 3-5 packaging belts in the circumference direction of the coil, wherein two belts must be wrapped on an outer protection angle ring, and the left are uniformly wrapped on the outer protection board.

Description

technical field

[0001] The invention relates to an outer packaging method for products in the metallurgical industry. Background technique

[0002] Cold-rolled stainless steel coils with a width greater than 1500mm are wide-width steel coils, and they are required to be packaged and transported before leaving the factory, which can better protect the surface quality and shape of the steel plate. The existing common packaging methods include simple packaging, ordinary packaging and fine packaging, all of which belong to the ordinary narrow-width steel coil packaging methods. If these ordinary packaging methods are used, wide-width steel coils often occur during storage, transportation, and lifting. The quality problems of steel coil surface quality reduction or plate shape change cause losses to the enterprise. Contents of the invention
