Abstract
The utility model relates to an electromagnetic radiation shielding method, belonging to the physical technical field, in particular to a hot flatness gauge small room of hot-rolled steel plant. The utility model adopts two steel plates to clamp a lead board, and uses bolts, nuts and gaskets to fix them into a radiation resistant plate to be mounted in a hot flatness gauge small room, near the multifunctional machine with radiation, near the wall at thickness gauges and on local floor. The utility model can limit the radiation dosage of hot flatness gauge small room in 2.5uSv as national standard, to protect the workers of hot flatness gauge small room in dangerous condition of X-rays, protect people health from X-rays, and prevent radiation dosage from exceeding standard in factories to avoid being punished by health department. The electromagnetic radiation shielding method can be widely applied in hot flatness gauge small room of hot-rolled steel plant or the buildings for preventing the radiation risk of X-rays.
Description
Technical field
The utility model belongs to the technical field of physical department, relates to a kind of electromagnetic radiation shielding method, is specifically related to a kind of hot-strip factory Straightness Meter houselet.
Background technology
Development along with iron and steel enterprise, quality requirement to hot-strip is more and more higher, and the hot-strip factory that medium-and-large-sized hot-strip factory all disposed X ray multi-functional instrument (being called profile gauge again), Straightness Meter behind finishing mill, have also has X-ray thickness gauge etc. to measure band steel parameter together.Straightness Meter is a laser measurement, and the data that its instrument supplier provides does not all relate to radiation-resistant requirement; The multi-functional instrument supplier only provides the curve of the X-radiation scope of C shape frame, and radiation proof is not proposed specific requirement yet.Along with the quality examination to the band steel requires more and more highlyer, in later hot-strip factory plant design in 2000, extensively adopt multi-functional instrument and Straightness Meter to measure.In order to prevent the harm of X ray to the intralocular staff's health of Straightness Meter, at the Straightness Meter houselet by the thick steel plate radiation proof of 25mm is installed on the wall of C shape frame side, when the distance of wall and C shape frame more than 1m, during safe dose 7.5 μ Sv, effect is pretty good.But, when the distance of wall and C shape frame less than 1m, and the stack of calibrator C shape frame X-radiation in addition, simultaneously, again because international standard and GB are brought up to factors such as 2.5 μ Sv with the safe dose of radiation by 7.5 original μ Sv, guarantee the intralocular staff of Straightness Meter can be in the environment of X ray harm trouble free service, health of human body is not subjected to X-ray injury, adds steel plate and can not solve the radiation proof problem effectively.
Summary of the invention
The purpose of this utility model is a kind of hot-strip of design factory Straightness Meter houselet.
The utility model adopts stereotype of two block plates folders with bolt, nut and the pad formation radiation proof board that tightens together, at the Straightness Meter houselet by the multi-functional instrument with radiation, the wall and the installation of terrace part of calibrator side.
More effectively X-ray-preventing radiation of the utility model, make the interior dose of radiation of Straightness Meter houselet in 2.5 μ Sv of national regulation, guarantee the intralocular staff of Straightness Meter can be in the environment of X ray harm trouble free service, health of human body is not subjected to X-ray injury, and factory avoids dose of radiation to exceed standard by hygiene department's heavy punishment.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is A of the present utility model---the A sectional view;
Fig. 3 is that B of the present utility model is to view;
Fig. 4 is that C of the present utility model is to view;
Fig. 5 is a D partial enlarged drawing of the present utility model.
Among the figure, part 1 is the Straightness Meter houselet, and part 2 is a multi-functional instrument, and part 3 is a calibrator, and part 4 is interior metope, part 5 is a terrace, and part 6,7 is a stereotype, and part 8,9 is a steel plate, and part 10 is a bolt, part 11 is a nut, and part 12 is a pad, and part 13,14 is an angle steel, and part 15 is other instrument such as Straightness Meter.
The specific embodiment
Below in conjunction with accompanying drawing specific embodiments of the invention are described further:
Multi-functional instrument C shape frame 2, calibrator C shape frame 3 are installed in hot-strip factory all on the track behind the finishing mill, when online position is measured on rolling centerline, stereotypes 6 of two block plates 8 folder and two block plates, 9 folders stereotype 7 usefulness bolt 10, nut 11, a pad 12 formation radiation proof board that tightens together, at Straightness Meter houselet 1 by the multi-functional instrument 2 with radiation, the wall 4 and the terrace 5 part installations of calibrator 3 sides.Stereotype 6 and steel plate 8 are made into rectangle, and its length is the same with the houselet interior wall long, height 2m～2.7m; Stereotype 7 and steel plate 9 are made into rectangle abnormal shape " spill ", and its length is smaller or equal to interior foundation length, width 0～1m, and the breach size of " spill " is determined by the instrument profile and the installation site of concrete other instrument 15 such as Straightness Meter.Radiation proof board again with angle steel 13 will around welding, the another side of angle steel and interior metope 4, terrace 5 surface soldered or fix with the bolt and nut packing ring, wherein the junction of stereotype 6 and steel plate 8 and stereotype 7 and steel plate 9 is fixed with angle steel 14 spot welding.
In view of the fusing point of lead is low, matter is soft, is guaranteed that by the temperature uniformity of indoor air-conditioning the temperature of stereotype is not toasted by hot strip steel.Guarantee that x-ray dose in the Straightness Meter houselet 1 is in 2.5 μ Sv.The thickness of stereotype 6,7 is according to the installation site and the radiation curve of multi-functional instrument, and the position that the Straightness Meter houselet is installed is determined.
For attractive in appearance, can refill ornamental steel plate and brush high temperature resistant paint on indoor steel plate 8 surfaces.Steel plate 9 surfaces in terrace refill steel plate and keep the smooth or dress movable floor in ground.
The utility model makes the interior dose of radiation of Straightness Meter houselet in 2.5 μ Sv of national regulation, guarantee the intralocular staff of Straightness Meter can be in the environment of X ray harm trouble free service, health of human body is not subjected to X-ray injury, and factory avoids dose of radiation to exceed standard by hygiene department's heavy punishment.
The utility model can be widely used in the hot-strip factory Straightness Meter houselet, and perhaps other prevents in the building of X-radiation harm.
