Abstract
The invention discloses a control technology of a hot-rolled steel plate, belongs to the technical field of hot-rolled steel plates, and aims to provide a simple, rapid and efficient control method of the hot-rolled steel plate to guarantee production of the qualified finished product. The technical scheme is as follows: the control technology of the hot-rolled steel plate sequentially comprises the steps as follows: 1) selecting a base material, namely, the SPHC steel plate, checking the outer surface of the steel plate, and ensuring that the steel plate is free of bubbles, cracks, scabs, layering, pull cracks and impurities; 2) detecting all indicators of the steel plate selected in Step 1), so that all the indicators are within the ranges as follows: the thickness is in a range of 2.0-8.0 mm, the allowable thickness variation is +/-0.05 mm, and the hardness is in a range of 42-50 HRB.
Description
Technical field
The invention discloses a kind of technique of steel plate control, specifically, is a kind of control technique of hot rolled steel plate, belongs to steel plate technical field.
Background technology
Hot rolled steel plate is made raw material by continuous casting steel billet or plate slab, heat through walking beam furnace, after high-pressure water descaling, enter roughing mill, roughing material is through crop, tail, enter finishing mill again, implement computer control rolling, after finish to gauge, pass through laminar flow cooling (computer control cooldown rate) and coiling machine and batch, become straight hair volume.Head, the tail of straight hair volume are often ligule and fish tail shape, and thickness, width accuracy are poor, and limit portion often exists the defects such as shape wave, flanging, turriform.
By straight hair volume, after the aligning of crop, back-end crop, trimming and multi-pass, the finishing line such as smooth are processed, then cutting plate or rewinding, become: the products such as hot rolled steel plate, smooth coils of hot-rolled steel, rip cutting band.If hot rolling finishing roll up after pickling scale removal oiling hot rolling acid-cleaning coiled sheet.This product has the trend of Part Substitution hot rolled plate, and moderate cost is liked by users deeply.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide one simple, control fast and efficiently the technique of hot rolled steel plate, to guarantee to produce qualified finished product.
For this reason, technical scheme provided by the invention is such: the control technique of this hot rolled steel plate, comprises the steps: successively
1) choosing base material is SPHC steel plate, checks steel plate outer surface, guarantees that steel plate is without bubble, flawless, without scabbing, without layering, without drawing crack with without being mingled with;
2) detecting step 1) indices of the steel plate chosen, make indices within following ranges: thickness 2.0～8.0mm's, thickness tolerance: ± 0.05mm; Hardness: 42～50HRB.
Further, the control technique of above-mentioned hot rolled steel plate, the steel plate that the preferred Anshan Iron &. Steel Group Corp of described steel plate produces, or the steel plate that Benxi iron and steel Co., Ltd produces, or the steel plate that the holding Co., Ltd of Magang Group produces, or the steel plate that the holding Group Co.,Ltd of iron and steel at sunshine produces, or the steel plate of packet header Dai Gang company production, or the steel plate of Taiwan Sinosteel Corporation production.
Compared with prior art, technical scheme tool provided by the invention has the following advantages:
1, the invention provides technical scheme, provide a kind of simple for controlling hot rolled steel plate, control fast and efficiently technique and standard, to guarantee to produce qualified finished product.
2, technical scheme provided by the invention, without professional technique operating personnel and special large-scale checkout equipment, has been saved production cost
Detailed description of the invention
Below in conjunction with detailed description of the invention; to the most further detailed description of claim of the present invention; but do not form any limitation of the invention, the amendment of anyone limited number of time making within the scope of the claims in the present invention, still within claim protection domain of the present invention.
Embodiment 1
A kind of middle control technique of rushing level hot rolled steel plate provided by the invention, the method comprises the steps: successively
