SHL-1.0
Lightweight, heat insulating refractory and high refractory products according to
DSTU 2342-94 (GOST 5040-96)
Chamotte lightweight refractories of SHL-1.0 grade found their use in metallurgical, glass industry, machine-building industry, and are used both in working lining of the furnaces not subject to exposure to molten metal and mechanical shocks, and in intermediate (protective) insulation.
Maximum temperature of their application is 1300°С.
The products are supplied on wooden pallets interlaid with cardboard, with protected corners, wrapped with stretch film and bundled with polypropylene or polyester strip.
