High temperature laboratory furnace annealing furnace refractory castable inspection

Furnaces, laboratory furnace, annealing furnace refractory castable must be required to conduct on-site measurements and the slump test block sample. Test and sampling devices used must meet the requirements and after checking.
1 reference block with pre-construction inspection. Furnace refractory castable before construction, mix design requirements should be made of the test block. Upon examination meet the requirements.
2 test block lien. Furnaces, laboratory furnace, annealing furnace refractory castable should be for each single project or mix brands, each 20m3 batch. Indwelling test block can be tested, also made a number less than this number of tests; every single project using the same grade or mix multiple construction, the construction of each test specimen shall be retained.
3 TESTING. Furnaces, laboratory furnace, annealing furnace unshaped refractory castable, etc. should be done TESTING project and the number of samples in accordance with regulations.
4 specimens conservation should be specified.
