Abstract

Предложены способ и уплотнительная конструкция (22) для герметизации зазоров (1) в кольце (2) из контактных башмаков. Уплотнительная конструкция (22) содержит огнеупорную ткань (12), которая согнута, по существу, в U-образную форму и имеет первую часть (13), прикрепленную с помощью огнеупорного клея к первой боковой кромке (7) первого контактного башмака (10), и вторую часть (14), прикрепленную с помощью огнеупорного клея ко второй боковой кромке (8) второго контактного башмака (11). По меньшей мере одна огнеупорная войлочная полоска (15) расположена между первой и второй частями (13, 14) для заполнения пространства между ними. Защитная полоска (16), выполненная из огнеупорного материала, прикреплена с помощью огнеупорного клея к боковым поверхностям (9) первого и второго контактных башмаков (10, 11).
