Abstract
The utility model relates to a P91 material checking test block of a portable Leeb hardness tester. The P91 material checking test block comprises an upper test block and a lower test block which are welded through a weld joint to form an integrated coplanar checking test block; the checking test block is a tile-shaped checking test block which is 150mm in length, 70mm in width and 65mm in thickness; and the weight of the checking test block is more than 5kg. By adopting the P91 material checking test block, the demand of field checking of the portable Leeb hardness tester can be met, and the error in field detection of the Leeb hardness tester also can be avoided; and the P91 material checking test block of the portable Leeb hardness tester is convenient to carry, convenient to manufacture, low in cost, applicable to a power plant and an electrical equipment manufacturing plant, wide in market and high in popularization value.
Description
Technical field
The utility model belongs to the alloy rigidity technical field of measurement and test, and especially a kind of P91 material of portable Leeb Hardness Tester is checked test block.
Background technology
At present, main steam, the reheaing steam pipe of the genset that 300MW is above generally use the P91 material, and it is one of main test item of checking and accepting P91 steel tubing and weld seam that hardness detects, and is also one of main test item of boiler genset pipeline periodic inspection.
The test block of the portable Leeb Hardness Tester one general configuration ordinary low-alloy steel of purchasing, but the P91 material belongs to high-alloy steel, after using low alloy steel test block adjustment sclerometer, use on the P91 material and larger error can occur, easily cause the false retrieval of pipeline mother metal and weld seam and undetected, bring potential safety hazard for electric boiler and genset.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of P91 material of portable Leeb Hardness Tester to check test block.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of P91 material of portable Leeb Hardness Tester is checked test block, and this check module comprises test block, lower test block, and it is whole that upper test block and lower test block are welded into isoplanar check test block by weld seam.
And described check test block is that length is 150mm, and width is 70mm, and thickness is that watt shape of 65mm is checked test block, checks the weight of test block greater than 5kg.
Advantage of the present utility model and good effect are:
1, P91 material of the present utility model is checked test block, is made of upper and lower test block and weld seam, has solved the on-the-spot demand of checking of portable Leeb Hardness Tester, has avoided the error of Leeb Hardness Tester Site Detection.
2,, P91 material of the present utility model checks test block, is easy to carry, easy to make, cost is low, in the generating plant, manufacturing plant is on-the-spot uses, and has ensured the requirement of hardness accuracy of detection.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described:
Embodiment described in the utility model is illustrative; rather than determinate; therefore the utility model is not limited to the embodiment described in embodiment; every by those skilled in the art according to other embodiments that the technical solution of the utility model draws, belong to equally the scope of the utility model protection.
A kind of P91 material of portable Leeb Hardness Tester is checked test block, as shown in Fig. 1 or 2, comprises test block 1, lower test block 3, and it is whole that upper test block and lower test block are welded into isoplanar check test block by weld seam 2.
In example of the present utility model, the P91 material tubing that described check test block is φ 457 * 65mm by specification processes, at first be two sections pipe rings of 35mm at P91 material pipe length direction intercepted length, again the two ends pipe ring is docked, integrally welded by the welding rod of identical material after docking, getting profound length after welding rod is integrally welded on the pipe ring round section is the profound of 150mm, by get and profoundly cut along the pipe ring axial direction, obtain checking test block, this check test block is that length is 150mm, width is 70mm, and thickness is that watt shape of 65mm is checked test block.
In example of the present utility model, the upper test block of described check test block and lower test block are used with the material welding rod and are welded, postwelding is heat-treated, and process conditions are: adopt U-shaped groove, the ER90S-B9 welding wire, the E9015-B9 welding rod, the manual argon arc welding bottoming, SMAW capping, 250～350 ℃ of preheatings, postwelding is incubated 2 hours 300～400 ℃ of after heat.Post weld heat treatment heating-up temperature (750 ± 20) ℃ is incubated 3 hours.
The weight of the utility model check test block satisfies the weight requirement of 5kg.
Use procedure of the present utility model is:
1, the desk-top Brinell tester HBZ-3000 that uses assay approval measures on lower test block and weld seam checking the upper of test block, and demarcates numerical value.
2, utilize portable Leeb Hardness Tester to measure checking test block, by demarcation numerical value and the measured value of checking test block, portable Leeb Hardness Tester is checked.
3, utilize the portable Leeb Hardness Tester after checking that field apparatus hardness is tested.
Claims (2)
1. the P91 material of a portable Leeb Hardness Tester is checked test block, it is characterized in that: comprise test block, lower test block, it is whole that upper test block and lower test block are welded into isoplanar check test block by weld seam.
