FIELD: chemistry. ^ SUBSTANCE: invention relates to the refractory industry and can be used in expendable lining or repair, carried out by gunite coating or plastering melting facilities, for example intermediate ladles, for making a buffer layer in metallurgical and thermal generating units. The fire-resistant gun mixture contains a fire-resistant aggregate, organic fibre, inorganic mineral fibre, synthetic fibre and binder. The binder is chemical-ceramic binder, and components are in the following ratio, wt %: organic fibre 0.7-2.0; inorganic mineral fibre 0.5-2.0; synthetic fibre 0.01-0.1; chemical-ceramic binder 3.5-5.0; fire-resistant aggregate - the rest. ^ EFFECT: improved heat insulation properties and stability of the gun mixture deposited on an article. ^ 2 cl, 1 tbl |
