Abstract
The invention relates to a roller taking dug iron as a base material, wherein the roller comprises a roller body; the roller body comprises a metal inner core and a high-hardness alloy layer covering the outer surface of the metal inner core. The manufacturing technology comprises the following steps: (1) processing a raw material into the shape of the roller; (2) covering the surface of the roller with an alloy layer; (3) cutting and polishing for molding; and (4) finishing. The roller and the manufacturing technology provided by the invention have the beneficial effects: 1. because a seamless steel pipe or a coiled plate does not have sand holes or shrinkage holes, the fastness degree of the roller is improved; 2. the seamless steel pipe or the coiled plate has multiple dimensions, rollers with various dimensions can be customized for customers; 3. the seamless steel pipe or the coiled plate is impact-resistant, and is difficult to crack; 4. the wall thickness of the seamless steel pipe or the coiled plate is uniform and smooth, the seamless steel pipe or the coiled plate can be cooled easily in the using process; 5. the damage of the novel roller can be repaired in the using process, and the novel roller does not need to be replaced with a new one; and 6. the alloy material of the surface of the novel roller can be flexibly replaced as required so as to meet the using requirement.
Description
Technical field
The present invention relates to a kind of roll, particularly relating to a kind of is the roll and the manufacture craft thereof of base material with wrought iron.
Background technology
Roll is the strength member on steel rolling mill's rolling mill; The pressure that produces when utilizing a pair of or one group of roll rolling rolls the stone roller steel; In the prior art, roll generally is to adopt the traditional handicraft cast molding, suitably adds alloying elements such as small additions of chromium, manganese; Make roller surface form harder chill, can roll the harder material of hardness to satisfy equipment.But the roll that this kind method is made has following defective: 1. because casting cycle receives weather and artificial and raw material factor affecting, in casting cycle, be prone to trachoma or shrinkage cavity, have a strong impact on the service life of roll; 2. casting receives the constraint of mould, can not arbitrarily change dimension of roller; 3. because the pig iron is met after cold more crisply, when low-temperature working, rupture easily, influence is used.4. pig iron spare makes the roll wall thickness thicker for guaranteeing the shock-resistant degree of self, in using continuously, is not easy heat radiation.5. pig iron roll is in use impaired can't repair, and it is high to change cost.
Summary of the invention
The objective of the invention is in order to solve the existing defective of roll in the prior art, providing a kind of is that the roll and the manufacture craft thereof of base material solves the problems referred to above with wrought iron.
To achieve these goals, technical scheme of the present invention is following:
A kind of is the roll of base material with wrought iron, comprises the roll body, it is characterized in that, said roll body comprises metal inner core and the alloy-layer that covers the high rigidity of core outer surface in the metal.
Above-mentioned a kind of be the roll of base material with wrought iron, it is characterized in that said metal inner core is a seamless steel pipe.
Above-mentioned a kind of be the roll of base material with wrought iron, it is characterized in that said metal inner core is the metal roll bending.
Above-mentioned a kind of be the roll of base material with wrought iron, it is characterized in that, said metal inner core with cover that the alloy-layer of core outer surface is dismountable structure in the metal.
A kind of is the manufacture craft of the roll of base material with wrought iron, it is characterized in that, may further comprise the steps:
(1) raw material is processed into the shape of roll;
(2) at roller surface covering alloy layer;
(3) cutting polishing moulding;
(4) accomplish.
The beneficial effect that the present invention has: 1. because seamless steel pipe or roll bending do not exist trachoma or shrinkage cavity, improved the firm degree of roll; 2. seamless steel pipe or roll bending size are many, enable to be customization various sizes roll; 3. seamless steel pipe or roll bending are shock-resistant, not easy fracture; 4. seamless steel pipe or roll bending wall thickness are even, smooth, make its cooling in the use easily; 5. new roller is in use impaired repairs, and does not need to change again; 6. new roller surface alloy material can change by instructions for use flexibly, to satisfy instructions for use.
Description of drawings
Fig. 1 is a structural representation of the present invention;
The specific embodiment
For making architectural feature of the present invention and the effect reached there are further understanding and understanding, cooperate detailed explanation, explain as follows in order to preferred embodiment and accompanying drawing:
Referring to Fig. 1, a kind of is the roll of base material with wrought iron, comprises the roll body, and the roll body comprises metal inner core 100 and the alloy-layer 200 that covers the high rigidity of metal inner core 100 outer surfaces.
Metal inner core 100 is seamless steel pipe or metal roll bending, because seamless steel pipe or roll bending do not exist trachoma or shrinkage cavity, has improved the firm degree of the roll of making; Moreover seamless steel pipe or roll bending size are many, enable to be customization various sizes roll, and seamless steel pipe or roll bending are shock-resistant, and easy fracture not, wall thickness is even, smooth, makes its cooling in the use easily.
The alloy-layer 200 of high rigidity can adopt alloying elements such as chromium, manganese to process, and the alloy-layer 200 that adopts alloying elements such as chromium, manganese to process has advantages such as high rigidity, high strength, can improve the hardness and the intensity of roll body, and it is impaired that it is not easy.The material of alloy-layer 200 use simultaneously also is very flexibly, not only is confined to two kinds of above-mentioned alloying elements.
Metal inner core 100 is dismountable structure with the alloy-layer that covers metal inner core 100 outer surfaces 200; When using the roll overlong time; After alloy-layer 200 has produced wearing and tearing; Can alloy-layer 200 be disassembled from metal inner core 100, the alloy-layer 200 that only need more renew just can be reused, and need not change a whole set of roll.
A kind of is the manufacture craft of the roll of base material with wrought iron, may further comprise the steps:
(1) raw material are processed into the shape of roll, raw material adopt seamless steel pipe or metal roll bending;
(2) at roller surface covering alloy layer, alloy-layer is the material of high rigidity, the hardness of agents enhance overall roll and intensity;
(3) cutting polishing moulding;
(4) accomplish.
In sum; Be merely preferred embodiment of the present invention; Be not to be used for limiting the scope that the present invention implements, all equalizations of doing according to the described shape of claim scope of the present invention, structure, characteristic and spirit change and modify, and all should be included in the claim scope of the present invention.
