Abstract

The invention discloses a cable sheath material for a hot blast stove. The cable sheath material for the hot blast stove comprises the following raw materials in parts by weight: 75 to 85 parts of base material, 0.5 to 1.2 parts of dicumyl peroxide, 0.1 to 0.6 part of triethylene diamine, 1 to 2 parts of ethoxylated trimethyol propane triacytate, 60 to 70 parts of a filling reinforcing agent, 0.8 to 1.6 parts of end vinyl polydimethyl siloxane, 0.4 to 1 part of dibutyltin dilaurate, 0.2 to 1 part of N-cyclohexyl-N'-phenyl diphenylenediamine, 0.2 to 1 part of 2,6-di-tert-butylphenol, 0.5 to 1.5 parts of 2,6-ditert-butyl-4-methylphenol, 1 to 3 parts of sorbitol, 1 to 2 parts of hydroxyl silicone oil, 1 to 2 parts of magnesium stearate, 1 to 2 parts of zinc stearate and 1 to 2 parts of polyurethane hot melt adhesive. The cable sheath material for the hot blast stove has high compactness, excellent ageing resistance and high heat stability under a long-term high-temperature condition.

Description

technical field [0001] The invention relates to the technical field of thermocouples, in particular to a cable sheath material for a hot blast stove. Background technique [0002] The hot blast stove is one of the main supporting equipment for the blast furnace in the ironworks. The function of the hot blast stove is to continuously provide high-temperature hot air above 1000°C for the blast furnace. Under the condition of ensuring the safe operation of the system, the temperature of the air supply is kept at 1000°C, and large fluctuations cannot occur. At present, the cables used for hot blast stoves developed by domestic manufacturers often deal with high-temperature environments, and the surface temperature of the cable sheath fluctuates greatly, which is easy to crack. After failure and disconnection, high-temperature, flammable, and explosive gases leak directly from the instrument. If it comes out, there are also great hidden dangers in safety, which need to be solved...
