5.1 sample sampling undertakes by GB10325.
5.2 sample preparation undertakes by GB7321,
5.3 exteriors pledge buy undertakes checking by GB10326.
5.4 chemical analysis have a test by GB6900.
5.5 apparent pore are led and density of body trifoliate orange has a test by GB2997,
Intensity of compression of 5.6 normal temperature has a test by GB5072,
Temperature of 5.7 loading bate presses GB5989 or YB/T370 has a test.
Stability of 5.8 thermal shock has a test by YB376.
The 5.9 heavy change that burn a line have a test by GB5988.
6 test gauge criterion
6.1 examine classification
Of firebrick examine minute of routine inspection test and type examine.
6.1.1 firebrick routine inspection test should include the following content: A) dimension deviation reachs exterior quality;B) apparent pore rate and bulk density; C) chemical component (Al2O3 and Fe2O3) ; D) loading bate begins temperature (T0.6 or T0.5) ;
The type of firebrick examines all item that Zuo eye should include place of the 4th chapter to list, the when normal production year at least regular inspection two.
6.2 sampling and check and accept
6.2.1 firebrick are approved by same brand clamp, every batches must not exceed 100t.
6.2.2 routine inspection test and the sampling that swing type to examine and check and accept undertake by GB10325, sampling amount is stuck mediumly with GB10325 on blast furnace brick.
7 marks, pack, carry and keep in storage
7.1 marks
The watch music of 7.1.1 bricks is used unplug the brand of the brick on Ming Yan color patch, level.
The two side of 7.1.2 packets of case need to indicate this the name of an article, norms, amount, level number, for name of square name or emblem mark, Fu Fang. Still must indicate careful put down gently, be afraid of wet reach hoisting mark.
7.2 pack
Use tray type container to pack, and with container load plan. packs box gross weight to must not exceed 1.2t.
7.3 carry and keep in storage
Carry the provision that must accord with GB10325 with keep in storage.
8 quality certificate
The beard when firebrick leaves factory is added those who put Piao of Piao of qualitative supervisory ministry to sign and issue is qualitative quick certificate, qualitative certificate should include the following content: A) offers square name; B) wants square name; C) delivers goods date; ; of D) contract sizeThis E) product name, level number, brand, level; Date of F) goods lot number, brick; G) examines result.
