Abstract
The invention relates to a packing method of hot continuous rolling steel strips. A two-step packing method is adopted for the packing method of the hot continuous rolling steel strips, the hot continuous rolling steel strips are prepackaged after passing through a recoiling machine, final packing is performed after steel coils are cooled (the temperature of the steel coils is lower than 200 DEG C), according to different thickness and width specifications of the steel coils, different pre-packing methods and final packing methods are selected, therefore, in the loading, unloading and transporting process of the hot continuous rolling strips, the coil scattering degree is substantially reduced, packing quality of the hot continuous rolling products is improved, and a downstream user can more smoothly hoist and uncoil the products.
Description
Technical field
The present invention relates to a kind of hot continuous rolling steel band packaging method, belong to hot continuous rolling steel band packaging technique field.
Background technology
Packing of product quality is the important component part of product quality in kind, and its quality directly influences product in the in the eyes of image of client.
The hot continuous rolling production process: steel billet enters heating furnace heating, carries out controlled rolling and control cooling after reaching target temperature and being incubated certain hour, be cooled to target temperature after, the hot continuous rolling steel band coils into coil of strip through taking-up equipment.After taking-up equipment comes out, pack, check then, put in storage.The purpose that the hot continuous rolling steel band is packed is to make coil of strip that the volume phenomenon of loosing not take place in loading and unloading, transportation.Because packaging method is unreasonable, the diffusing volume of hot continuous rolling steel band phenomenon is outstanding, has potential safety hazard in loading and unloading, transportation, influences the downstream client simultaneously and uses.
Current hot continuous rolling production line is general to adopt online packing to be combined with manual packing manner, namely batches the back that finishes coil of strip is carried out online circumferential packing, manually radially packs at warehouse for finished product then.It is higher that coil of strip batches the back temperature that finishes, in the warehouse for finished product cooling process, because the inherent inhomogeneous cooling of coil of strip is even, and the outside face tension, the inside face pressurized, the cooling of coil of strip two ends is fast, and central authorities' cooling is slow, thereby forms the uneven situation of distribution of stress at the coil of strip diverse location.If packaging method is unreasonable, then cause strap in processes such as loading and unloading, transportation, to rupture easily, the diffusing volume of coil of strip takes place, make the user can't lift, use.

Summary of the invention
The purpose of this invention is to provide a kind of hot continuous rolling steel band packaging method, solve the problem of the volume that looses in coil of strip loading and unloading, the transportation.
Technical scheme of the present invention is: a kind of hot continuous rolling steel band packaging method of the present invention, adopt two step bolus dressings, the first step is that the coil of strip after the hot continuous rolling steel band is batched through reeler is packed in advance, and second step was to carry out whole packing when steel roll temperature is cooled to below 200 ℃.
After hot continuous rolling steel band of the present invention batches through reeler, according to the pre-packing of classifying of coil of strip specification.
The described classification step of packing in advance is: when coil of strip thickness specification h≤6mm, width specifications w≤1800mm coil of strip is circumferentially made a call to 1 road tie, the tie position is coil of strip Width 1/2 place; When thickness specification h≤6mm, width specifications 1800mm＜w≤2250mm, coil of strip is circumferentially made a call to 2 road ties, the tie position is coil of strip Width 1/4,3/4 place; When thickness specification 6mm＜h≤25.4mm, width specifications w≤1800mm, coil of strip is circumferentially made a call to 2 road ties, the tie position is coil of strip Width 1/4,3/4 place; When thickness specification 6mm＜h≤25.4mm, width specifications 1800mm＜w≤2250mm, coil of strip is circumferentially made a call to 3 road ties, the tie position is coil of strip Width 1/4,1/2,3/4 place.
After steel roll temperature of the present invention is lower than 200 ℃, according to the whole packing of classifying of coil of strip specification.
Described classification packing step eventually is: when thickness specification h≤6mm, width specifications w≤1800mm coil of strip is circumferentially increased by 2 road ties, increasing the tie position is coil of strip Width 1/4,3/4 place, radially increases by 3 road ties and radially is evenly distributed; When thickness specification h≤6mm, width specifications 1800mm＜w≤2250mm, coil of strip is circumferentially increased by 2 road ties, increasing the tie position is coil of strip Width 1/8,7/8, radially increases by 3 road ties and radially is evenly distributed; When thickness specification 6mm＜h≤25.4mm, width specifications w≤1800mm, coil of strip is circumferentially increased by 3 road ties, increasing the tie position is coil of strip Width 1/8,1/2,7/8 place, radially increases by 3 road ties and radially is evenly distributed; When thickness specification 6mm＜h≤25.4mm, width specifications 1800mm＜w≤2250mm, coil of strip is circumferentially increased by 2 road ties, increasing the tie position is coil of strip Width 1/8,7/8 place, radially increases by 4 road ties and radially is evenly distributed.
The invention has the beneficial effects as follows hot continuous rolling steel band diffusing volume rate in loading and unloading, transportation is significantly reduced, hot continuous rolling packing of product quality gets a promotion, and operation such as downstream user lifting, uncoiling is more smooth.
