Description
Technical field
The present invention relates to testing tool in the steel pipe's production, the method for particularly a kind of core rod support roller height measuring rule and measurement thereof.
Background technology
Plug is one of main warp tool of the Φ 250MPM of tube rolling factory retained mandrel tandem rolling tube machine, needs import always, and is worth costliness, and its consumption accounts for 60% of rolling cost.Rationally using plug, is one of important process that reduces production costs the serviceable life of fully improving plug.
The core rod support roller height is the normal key link of using of assurance plug, and when core rod support roller height control precision did not reach standard, plug consumption increased and makes steel pipe internal-surface interior rib defective occur easily.The former design of core rod support roller height measuring is the distance of measuring between tooth bar slide rail lathe bed bottom surface and the plug, uses ruler, interior card, vernier caliper to measure.During measurement, plug is put into plug and supports, at least need two people to cooperate, one human ruler props up tooth bar slide rail lathe bed bottom surface, card is measured the distance (being the distance between tooth bar slide rail lathe bed bottom surface and the plug) between ruler and the plug in another human, two people must be in the slit between slide rail and the plug during measurement, hand is reached below tooth bar slide rail and the plug, general plug temperature is about 100 ℃, the scald accident easily takes place in the work, if the core rod support roller catastrophic failure can cause serious injury to the arm of measuring the people.This measuring method order of accuarcy is poor, because slide rail is in the chilled water pouring for a long time, the greasy dirt dust corrodes, is under the environment of more than 1000 degree high-temperature bakings by the hollow billet temperature, there is the iron scale layer slide rail bottom surface, after being subjected to ruler degree of crook, macroporous type to transform the diameter of mandrel increasing, slit between slide rail and the plug becomes very little, below arm can't reach, measure very difficulty of core rod support roller height.
Summary of the invention
For solving the problem of above-mentioned existence, the method that the purpose of this invention is to provide a kind of core rod support roller height measuring rule and measurement thereof, be beneficial to solve to measure carry out difficulty, measurement is inaccurate, operating process is dangerous, be beneficial to reach measure safety, fast, purpose accurately, improve and measure order of accuarcy.
For achieving the above object, the technical solution used in the present invention provides a kind of core rod support roller height measuring rule, this dip stick is placed on the bottom and has on the tooth bar slide rail of ruler, wherein: this dip stick includes dip stick crossbeam 1, be connected with dip stick column 2 respectively with dip stick crossbeam 1 two ends, form a U type framework, be provided with dip stick base 3 in the end of dip stick column 2.
A kind of method by above-mentioned dip stick measurement core rod support roller height measuring also is provided simultaneously, and this method may further comprise the steps:
1. the described dip stick of claim 1 is placed on the tooth bar slide rail 4;
2. by lifting backing roll 6 control plugs 7 height;
3. distance between plug 7 and the dip stick crossbeam 1 is adjusted to the setting value of this size mandril backing roll height H.
Effect of the present invention be this method found above tooth bar slide rail bed and the plug and tooth bar slide rail lathe bed bottom surface and plug between an equidistant height, be made into behind the dip stick through with original measuring method relatively, simple, practical, safety, advantage are accurately and fast arranged.
After using novel dip stick, the core rod support roller height measuring accuracy improves, and plug uses normal, and loss per ton steel has met and exceeded former design level.And it is smooth that macroporous type is transformed.From security standpoint, from the method for last measurement, reduced the possibility of scald accident, eliminated the core rod support roller catastrophic failure, avoided causing the possibility of measuring the human arm grievous injury.Arm reaches the potential danger that causes in the slit between plug and slide rail when having avoided measuring, and improves the order of accuarcy of measuring, and further reaches the saving plug, the purpose of improving the quality of products.

Embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated the method use of core rod support roller height measuring rule of the present invention and measurement thereof.
As shown in Figure 1, the structure of this core rod support roller height measuring rule is to comprise by dip stick crossbeam 1, is connected with dip stick column 2 respectively with dip stick crossbeam 1 two ends, forms a steel " U " type framework, is provided with dip stick base 3 in the end of dip stick column 2.
As shown in Figure 2, change under measure the core rod support roller height H ' for from last measurement core rod support roller height H.According to the constant principle of rolling centerline height, former design rolling centerline and plug central lines, by the method for above-mentioned dip stick measurement core rod support roller height, this method may further comprise the steps:
1. the described dip stick of claim 1 is placed on the tooth bar slide rail 4;
2. by lifting backing roll 6 control plugs 7 height;
3. distance between plug 7 and the dip stick crossbeam 1 is adjusted to the setting value of this size mandril backing roll height H.
With 291 pass diameters is that 277.1 plugs are example, rolling centerline absolute altitude h
0Be 6900mm, tooth bar slide rail rail level absolute altitude h
1Be 6800mm, the core rod support roller height just plug 7 to the distance H of novel dip stick crossbeam 1, must equal to measure originally the core rod support roller height and be plug 7 to the distance H that props up tooth bar slide rail bottom surface ruler 5 ', plug 7 diameter D=2 * R and core rod support roller height H, H ' are known (seeing attached list one), and the tooth bar slide rail equals 2 elevation difference Δ h=h to the distance h of rolling centerline
0-h
1Core rod support roller height measuring rule base 3 is placed on and measures the core rod support roller height H on the tooth bar slide rail 4, and the height of core rod support roller height measuring rule just tooth bar slide rail 4 then can calculate the height of novel dip stick to the distance L of dip stick crossbeam 1:
L＝H+R+Δh
Δh＝H+R+(h
0-h
1)
With 291 pass diameters is that 277.1 plugs are example, and the height L of core rod support roller height measuring rule is:
L＝86.4+277.1/2+(6900-6800)＝324.95mm
