Description
Technical field
The utility model belongs to steel continuous casting and rolling apparatus field, is specifically related to a kind of seamless pipe continuous casting continuous rolling equipment, mainly comprises continuous casting hollow billet machine, tandem mill and finishing equipment.
Background technology
At present, the technique of domestic and international production seamless pipe is, after smelting continuous cast round billets cooling, be transported to steel rolling mill, be heated in rotary heating furnace and need temperature to bore a hole, complete production tube production through the operation such as tandem mill, finishing equipment, needed for this production technology, production equipment is loaded down with trivial details, and floor space is larger, production line is dilatory, production cycle is long, and energy and resource loss are wasted greatly, greatly have impact on the further lifting of seamless pipe production efficiency and product quality, simultaneously, because operation is numerous and diverse, equipment is more, adds the loss of electric energy and heat energy.
Summary of the invention
The purpose of this utility model is the above-mentioned shortcoming in order to improve existing production seamless pipe instrument and supplies, propose a kind of by continuous casting perforation process and be a procedure, meanwhile, continue tandem mill after continuous casting hollow billet equipment, makes full use of the seamless pipe continuous casting continuous rolling equipment of hollow billet preheating.
For reaching above-mentioned purpose, a kind of seamless pipe continuous casting continuous rolling equipment of the utility model, described equipment comprises the continuous casting hollow billet machine, tandem mill and the finishing equipment that connect successively, described continuous casting hollow billet machine comprises ladle, tundish, crystallizer, secondary cooling system, draws steel equipment and cutting equipment, a center column is provided with in described crystallizer, described center column is double-layer sleeve structure, and upper end is provided with water inlet and the delivery port of connection, for the molten steel in circulating cooling crystallizer.
The centre of wherein said center column is provided with described water inlet, and peripheral position is provided with described delivery port.
Wherein said water inlet is 1, and described delivery port is multiple and is uniformly distributed on described peripheral position.
The utility model seamless pipe continuous casting continuous rolling equipment difference from prior art is that the utility model achieves following technique effect:
1, the utility model adopts the one-shot forming of continuous casting hollow billet, changes traditional seamless pipe manufacturing process, saves round base cost of transportation, cancelled rotary heating furnace and perforating apparatus, thus, have processing technology easy, equipment is few, the features such as floor space is reduced in a large number, manufacturing cost reduction;
2, the hollow billet of the utility model continuous casting forming carries out band warm-rolling system, makes full use of hollow billet waste heat, has thus saved the energy and power supply;
3, the utility model hollow billet is formed by casting in casting process, and do not affect by rubbing and tear in the perforation procedure of top, there is not defect in inner surface problem, therefore hollow forging inner surface quality is good, and the seamless pipe lumber recovery after rolling will improve greatly;
4, the utility model is owing to simplifying the technological process of production and equipment, therefore, greatly reduces the loss of ferrous materials and manufacturing equipment;
5, the utility model hollow billet continuous casting forms, and rolled piece is in deformation process, and stress state is good, and be therefore applicable to some hardness high, plasticity is poor, the seamless pipe of thermal deformation difficulty.
Below in conjunction with accompanying drawing, the utility model is described in further detail.

Detailed description of the invention
Below in conjunction with drawings and Examples, to above-mentioned being described in more detail with other technical characteristic and advantage of the utility model.
As shown in figures 1 to 6, a kind of seamless pipe continuous casting continuous rolling equipment of the utility model, described equipment comprises the continuous casting hollow billet machine connected successively, tandem mill 11 and finishing equipment (sizing mill 14), described continuous casting hollow billet machine comprises ladle 2, tundish 3, crystallizer 4, secondary cooling system 8, draw steel equipment 9 and cutting equipment 10, a center column 5 is provided with in crystallizer 4, center column 5 is double-layer sleeve structure, upper end is provided with water inlet 6 and the delivery port 7 of connection, for the molten steel 1 in circulating cooling crystallizer 4, water inlet 6 is 1 centre being positioned at center column 5, delivery port is 2 peripheral positions being symmetrically distributed in center column 5.
The molten steel that satisfied temperature and composition etc. require is by ladle 2, tundish 3, surface solidification is completed in tubular crystallizer 4, cooled by secondary cooling system 8, described continuous casting hollow billet machine is pulled out with certain speed under the effect of drawing steel equipment 9, the employing cutting equipment 10 pairs of hollow billets that need according to follow-up tandem mill 11 cut, and utilize hollow billet own temperature to complete tandem rolling, adopt sizing mill 14 sizing, reduce or remit round base again to heat and perforation process, directly for heat-treatment lines provides light pipe 15.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
