The problem

Refractory products pass room-temperature compression yet crumble at over 1000 degrees C in the kiln; high-temperature compression data is missing; improvised setups of a press plus muffle furnace drift tens of degrees and nobody accepts the numbers.

Capability

Bench meets GB/T 34218-2017 for measuring the high-temperature compressive strength of refractory products in metallurgy, commodity inspection, universities and research institutes. Furnace chamber 200x200x200mm, working temperature 1050 degrees C and maximum 1500 degrees C, heating rate 0-10K/min (0-1000) and 0-5K/min (1000-1500), stability plus/minus 1K, fully programmable control; oxidizing atmosphere with coke-bed protection for carbon-bearing materials. Loading up to 100kN (10MPa) with class 1 indication, driven by servo motor, gearbox and ball screw for continuous adjustment; digital force display with peak hold, PC communication for dynamic curves, optional strain sensor for stress-strain output. Frame-type machine 600x800x1600mm, about 1000kg; AC380V/50Hz with 5kVA transformer. Software offers bilingual interface, user-defined test items, statistics (mean, standard deviation, coefficient of variation), curve analysis, traceability and Word/Excel reports; standard accessories include door block, tongs, high-temperature gloves, two spare heating elements and one thermocouple.
