Description

Make the method for steel part

The present invention relates to a kind of method of making steel part.Particularly, the present invention relates in the middle of the steel part for example plain plate of all thickness and the round steel rod and the downstream process of various diameters.For example, the present invention relates to be used for I type cross section, H type cross section, round cross section or the similar technology of steel part with the cross-sectional configuration of plain plate production regulation L type cross section for example.

In fact, different with numerous general steel part manufacture methods, method of the present invention is to want to make neatly to have the wide goods of scope that change configuration.In this respect, by convention, the steel producer only can provide narrow goods and/or raw material, like this, needs various different makers so that the goods of proper range are provided.

So, the invention provides a kind of method of making steel part, this method comprises routine step down: raw material are sent to a feeding unit, so that tentatively prepare raw material, the raw material that prepared are sent on the ring device so that material itself is optionally arranged, ring device plays cushioning effect to guarantee that material is with stabilized speed roughly, irrelevant with material by the speed of feeding unit, be fed in the next step of technology, then, material is sent to a building mortion from ring device, so that make material carry out physical change, result, produce shaped steel with required form and cross section, process these shaped steel then in last processing unit (plant), the result produces required steel part.

The present invention also provides a kind of equipment of producing steel part, this equipment comprises the feeding unit that is used for raw material are sent to loop device, ring device is such, it allows raw material self optionally to arrange, to guarantee the speed of raw material with constant, irrelevant with the speed that raw material enter in the ring device, leave ring device, this equipment also comprises ring device, be used for physical change is imposed on the shaped steel that has required form and cross section on the raw material with production, also comprise final processing unit (plant), be used for those shaped steel is processed into the final steel goods.

From in broad terms of the present invention, this method realizes under " cold " state that at first this steel part is cold-rolled products.Yet, by for example introducing one heater between ring device and building mortion, as, heating furnace, technology of the present invention and equipment also can be produced hot-rolled product.In fact, owing to can therefore,, preferably have heating furnace for heating furnace adds lie or heating furnace is not worked no matter whether need hot rolling or cold rolling.

Heater can be the known heating furnace that is used for any pattern of present technique specialized application, yes, and this heating furnace is preferably in its both sides respectively has two rollers, roller is as clamping device so that with certain strength clamping material, can be not tight during heating furnace work thereby guarantee material La Detai, can not make material relax to a degree of damaging yet.In addition, preferably control the speed that transmits by heating furnace carefully, to help to form sufficient and consistent heating.In this respect, the heating-up temperature in the heating furnace is preferably in 950 ℃ scope.

Feeding unit can be configured to a single unit maybe can be the unit of several separation.In better form, raw material can be introduced into a uncoiler, so that this material can be admitted to next process segment as the crow flies.Yet,, can not need to show raw material because raw material can be rod or sheet material (they or be arranged to plate-like or be arranged to flat board).In addition, if raw material are configured to the form of bar or plate-like, then need welding step so that the end of each rod or dish is coupled together to guarantee continuous rolling.In this respect, if when saving welding machine and raw material and being bar or dish since need usually manpower each stage continuously new building or rod again in the introducing equipment, then this technology can not automatically be carried out.

Feeding unit also can have a pinch roll, and it is as leading so that material is introduced and sent in the ring device.

After ring device and the building mortion that before final processing unit (plant), in technology of the present invention, provides also can be configured to a single unit or several separative elements.Like this, building mortion can have straightener or flattening machine, is used for straighteing material to guarantee can carry out straight basically material the further processing of material when material leaves ring device.Certainly, if having a heating furnace in the method for the invention, so preferably after this straightener, have this stove.

Building mortion is preferably with its chief component-be divided into and rolling unit, to give the physical change of material shape, thereby produce cross section, resemble the bar of minor diameter, the shaped steel of L type, I type, H type, U type, round section and other type with required form.In this unit, power is imposed on material is compressed or reduces processing by being positioned at the vertical and horizontal roll that makes profile in advance with rolling unit of being shaped.

In this respect, by tightly being arranged on shaping and the rolling unit after the heating furnace, hot-finished material at once is so that make finished section produce the configuration of accurate dimensions.

In fact, in this way, can make section bar have sharp-pointed edge, rather than the rounded edge of in such rolling mill, producing usually.This sharp-pointed edge makes the section bar of being produced by its radius of corner of increase have additional strength and enhancing.

In addition, heating furnace be positioned at be shaped and rolling unit before, when material by being shaped and during rolling unit, the malleability of combination easily allows to produce various cross sections from a kind of operation, rather than common by independent such that rolling mill presented.

Moreover building mortion can have another straightener to help to align and/or flatten the shaped steel that leaves shaping and rolling unit.

At last, final processing unit (plant) of the present invention can be a cutting device simply, also can be a devices for taking-up, and this depends on the character of needed final steel goods.Final processing unit (plant) also can have needed packing device.

Referring now to accompanying drawing, the present invention will be described.In this respect, it must be understood that, below describe and do not limit generality described above.Among the figure:

Fig. 1 be according to a preferred embodiment of the present invention technology and the schematic diagram of equipment.

Shown in Figure 1 is to be divided into trizonal technology circuit for ease of reference.This processing line comprises raw-material supply, and steel rod is to coil 10 form supply in the present embodiment.Steel rod is by feeding unit, and this feeding unit has uncoiler 12 and pinch roll 14, and they guarantee that together steel rod moves and accurately import the next stage of this technology as the crow flies.

The next stage of this technology is a ring device 16, herein, material self is optionally arranged so that form buffering, and is irrelevant by the speed of pinch roll 14 feedings with material to guarantee material with constant speed, is fed into the next stage of this technology.

Aligning or flattening machine leave this material of aligning behind the ring device and send into the heater that the form with heating furnace 20 provides with convenient material after ring device 16.

It enters building mortion when material leaves heating furnace 20, the chief component of this building mortion is to be shaped and rolling equipment 22, this equipment 22 gives Material Physics and changes the shaped steel that has required form and cross section with production, by being positioned at power being imposed on the material so that material produces and is compressed in this unit and reduces processing by the roll 24 of predetermined configuration design of this equipment.

This processing line comprises a final processing unit (plant) at last, and it only is a kind of cutting and piling apparatus 26 in this specific embodiment, and it can cut into the steel part with Len req to final rolling goods.

Should be understood that, method and apparatus is as described above made other modifications and variations, fall into too within the scope of the present invention.
