Изобретение относитс  к огнеупорным массам и может быть использовано при производстве изделий например, труб, подвергаемых высокотемпературному нагреву с последующей деформацией.The invention relates to refractory masses and can be used in the manufacture of products such as pipes subjected to high-temperature heating and subsequent deformation.

Известна огнеупорна  масса, содержаща  метасиликат натри , глинозем и воду.A refractory mass containing sodium metasilicate, alumina and water is known.

Цель изобретени  - увеличить прочность и термостойкость.The purpose of the invention is to increase strength and heat resistance.

Это достигаетс  тем, что она дополнительно содержит графит, при следующем соотноше%;This is achieved in that it additionally contains graphite, with the following ratio of%;

Приготавливают обмазку путем механического смешивани  глинозема, метасиликата натри  и графита.A wash is prepared by mechanically mixing alumina, sodium metasilicate and graphite.

Подогрев обмазки до 60-80°С ускор ет процесс сцеплени  с металлом. Глинозем ввод т дл  обеспечени  и повышени  термостойкости обмазки и уменьшени  разрушающего взаимодействи  нагреваемого металла с кладкой пода печи.Heating the coating to 60-80 ° C accelerates the adhesion process to the metal. Alumina is introduced to ensure and improve the heat resistance of the coating and reduce the destructive interaction of the heated metal with the laying of the furnace floor.

Достаточна  толщина покрыти  0,1-0,5 мм. .Применение предлагаемой обмазки при производстве гор чекатаных труб снижает потери металла в окалину в 1,5-3 раза и увеличивает длительность эксплуатации печи между очередными чистками пода от окалины в 1,5- 3 раза.A sufficient thickness of the coating is 0.1-0.5 mm. .The application of the proposed coating in the production of hot-rolled pipes reduces the loss of metal into scale by 1.5–3 times and increases the duration of operation of the furnace between the next cleanings of scale from the scale by 1.5–3 times.

Нанос т обмазку на издели  любым из известных способов, в частности, путем окунани , распылени . Обмазка дешева, не дефицитна , обладает высокими защитными свойствами при 1300°С.The coating is applied to the products by any of the known methods, in particular, by dipping, spraying. The coating is cheap, not scarce, has high protective properties at 1300 ° C.
