Embodiment Construction

[0015] A high-temperature-resistant inorganic sealing gasket of the present invention is composed of an inner sleeve and an outer sleeve. The inner sleeve is made of nylon thin fleece-proof cloth as the inner layer, and the inner sleeve is filled with powdery refractory cement; the outer sleeve is made of ceramic fiber Made of percale and used as the outer layer. The outer sheath is set on the outside of the inner sheath, that is, the outer layer of the inner sheath is sheathed on the inner layer of the outer sheath. Because what inner layer cover selects for use is the nylon thin fleece-proof cloth, and its thickness is very thin, and the size of inner layer cover and outer layer cover are basically the same.

[0016] Adopt by the preparation method of high temperature resistant inorganic gasket of the present invention, its manufacture process is as follows:

[0017] The inner layer cover is made of nylon thin anti-velvet cloth, and its shape and size are according to the s...

Abstract

An inorganic and high temperature resisting seal washer is prepared as forming said seal washer by inner wear and outer wear, using nylon thin cloth to prepare inner wear and using it as internal layer, packing powder shape fire-resisting clay in inner layer wear, using ceramic fiber microgroove cloth to prepare outer wear and using it as external layer, jacketing external layer wear on internal layer wear and sewing internal layer wear and external one together.

Description

technical field [0001] The invention relates to a gas shielded furnace in a galvanizing process, in particular to a high-temperature-resistant inorganic sealing gasket arranged on a gas shielded furnace box and a preparation method thereof. Background technique [0002] Metallurgical system iron and steel manufacturing enterprises in the process of producing galvanized sheets, in order to ensure product quality, use a gas protection furnace in the galvanizing process. The furnace box is equipped with upper and lower covers to provide technical and maintenance protection. need. In the production process, in order to prevent the intrusion of external gas, the sealing requirements of the box cover are very high, because the furnace body is in contact with molten zinc metal, and the furnace temperature is as high as about 420 °C. [0003] The sealing part of the furnace box is provided with two parallel grooves, the total length and width of which are 3m×1.5m, and the depth and...
