Be carbon steel to be fused into molten steel, the molten wheel of taking out that has indentation and can rotate at a high speed be installed then on molten steel near the molten steel face by electric furnace.Because molten rotation of taking out wheel has thrown away molten steel come, be connected with cooling water in the wheel molten taking out, molten steel coagulates rapidly because of becoming steel fibre.
The problem that exists: energy consumption height; And in the steel fibre forming process, the oxide layer that the surface produces can influence its service property (quality).
2, the process of chopping
Cutting off steel fibre is the steel wire length cut-out on demand that will coldly be allocated to certain diameter with cutting machine, and being pressed into needs shape again.
The problem that exists: special raw material, price height; Need to cut off and shaping two procedures link; Production efficiency is low.
3, milling method
The milling of steel fiber is by steel plate or steel ingot, forms with the plain milling cutter machining of rotating.
The problem that exists: raw material is finished product or semi-finished product steel, and price is higher; Equipment investment is big.
4, shearing method
Be with certain thickness band steel, use the cutter of rotary cutting, steel is sheared the steel fibre that is twisted into rectangular cross section.
The problem that exists: raw material is band steel time material, and price is higher, resource-constrained; The palpus preliminary working becomes the band steel of certain width; Production efficiency is low.This shearing is high only carries out lateral shear to steel bar.
The object of the present invention is to provide a kind of with steel band, particularly steel rolling mill to produce the side cut steel scrap band that thin plate produces be raw material, make the production method of steel fibre by connecting processing technology.
For realizing purpose of the present invention, the inventor propose with steel rolling mill produce side cut steel scrap band that thin plate produces be the process program of raw material be smooth, roll and cut, press shape, disjunction four procedures to be combined into integral production technology in order, each inter process is connected mutually, synchronous operation, the disposable production process of finishing steel fibre.Wherein:
Smooth: as by smooth roller the steel band bar to be carried out smoothly, make steel band bar sclerosis.
Roll and cut: cut roller by rolling of roller marginal zone cutter and vertically the steel band bar after smooth is rolled and be cut into the finer wire bar;
Press shape: be pressed into required form by the finer wire bar of pressing the shape roller will roll after cutting;
Disjunction: laterally will press finer wire bar disjunction after the shape by the branch roll breakage of roller marginal zone cutter;
Above-mentioned operation synchronous operation.
1, this technology solves existing manufacturing technique requirent and causes the high problem of cost of material
The aforementioned process of chopping, milling method, shearing method raw materials for production are finished product, semi-finished product steel or inferior, and price is higher, though the molten method of taking out is done raw material with steel scrap, and the palpus melting, the energy consumption height, expense also can increase.
At present each steel rolling mill of the whole nation produces thin plate and the side cut steel scrap band that produces, and the Chang Zuowei waste material all melts down processing at last.General heavy steel rolling mill year produces 10,000 tons on steel scrap band, and the steel sibre continuous equalizing rolling-cutting shape-moulding cutting-off method of our research and development aimed at this huge cheap raw material resource just, with the primary raw material of side cut steel scrap band as this processing technology.
2, this technology solves the existing problem that process procedure is more, production efficiency is low
The aforementioned milling method of removing, other method all can not disposablely be finished the production process from raw material to steel fibre.The steel sibre continuous equalizing rolling-cutting shape-moulding cutting-off method production technology can the overall process of disposable realization from the steel band to the steel fibre, and energy consumption is low, simple to operate, can stepless transposing roll the speed of cutting, thereby enhance productivity.
3, this technology solves the problem that existing technical process is organized large-scale production
The steel fibre production equipment separate unit price of making according to the steel sibre continuous equalizing rolling-cutting shape-moulding cutting-off technological principle is low, and floor space is little, the production efficiency height.Be equipped with ten and just can build up ton steel fibre factory, the equipment gross investment is less, the raw material abundant information, and cost of material is low.
