Abstract
The utility model relates to the technical field of the production of heavy machinery, in particular to a high-rigidness surface steel-plate ring round hardened roll. The hardened roll is provided with a roll tube and an end plate, wherein a coating covers the outer surface of the roll tube, the end plate is concentrically connected with a rotating shaft, and the inner wall of the roll tube is provided with positioning blocks which are distributed along the circumferential direction. Due to the adoption of the high-rigidness surface steel-plate ring round hardened roll, the surface rigidness of the hardened roll is enhanced, the surface oxidation is prevented, the surface coarseness of a finished product is guaranteed, the production efficiency is improved, and the cost is reduced.
Description
Technical field
The utility model relates to the heavy-duty machinery production technical field, especially a kind of high firmness surface steel sheet formula circle quenching roller.
Background technology
Along with the input of automobile rolling mill production line, produce the high-grade auto sheet widespread use of high added value, domestic increasing iron and steel manufacturing concern will set up the rolling mill production line of high-end product.Like Baosteel five cold rolling CAPL and CGL production line is the external state-of-the-art rolling mill production line of present domestic machine, mainly produces high-grade auto sheet, increasingly high to the specification of quality of belt steel surface; And the production rate of band steel is more and more faster, and therefore increasingly high to the requirement of all rollers on the production line, roll surface does not have hardness requirement yet; At outside surface spraying hard chrome plating; In use be pressed into pit or convexity by impurity easily, finished strip just face form and to draw trace or trace, the surface quality of influence band steel.
The utility model content
The technical problem that the utility model will solve is: overcome the deficiency in the prior art, a kind of high firmness surface steel sheet formula circle quenching roller is provided.
The utility model solves the technical scheme that its technical problem adopted: a kind of high firmness surface steel sheet formula circle quenching roller; It has roller and end plate; Be coated with coating on the outside surface of described roller; Connection rotating shaft that end plate is concentricity, the inwall of roller are provided with the preset pieces that along the circumferential direction distributes.
Further, the wall thickness of the described roller of the utility model is at 15~25mm.
The beneficial effect of the utility model is: the utility model has strengthened the quench roller surface hardness, prevents surface oxidation, guarantees the roughness of finished surface, enhances productivity, and reduces cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. rollers among the figure, 2. end plate, 4. rotating shaft, 5. coating, 6. preset pieces.
Embodiment
Combine accompanying drawing that the utility model is further described now.The synoptic diagram that these accompanying drawings are simplification is only explained the substruction of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of high firmness surface steel sheet formula circle quenching roller as shown in Figure 1; It has roller 1, and left and right end plate 2,3 is coated with coating 5 on the outside surface of roller 1; Left and right end plate 2,3 concentricity connection rotating shafts 4, the endoporus hole wall of roller 1 are provided with the preset pieces 6 that along the circumferential direction distributes.The cylindrical of left and right end plate 2,3 respectively with roller 1 both ends endoporus shrink-fit, and shrink range is in 0.30~0.50mm scope.The wall thickness of roller 1 can ensure not only that at 15~25mm roller 1 is little through the quenching strain amount after quenching, and can not produce heat treatment crack, also can reduce material usage, to overcome the deficiency of prior art, realizes the purpose of the utility model.
Above-mentioned embodiment is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage that is familiar with this technology can understand the content of the utility model and implements; Can not limit the protection domain of the utility model with this; All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the utility model.
