Special cable for buggy ladle

Abstract

The invention discloses a special cable for a buggy ladle. The special cable for the buggy ladle structurally comprises an outer protective casing and a conductor core in the protective casing, wherein the conductor core consists of a tensile resistant strengthening inner core in the middle and a copper bundle wire core at the periphery of the inner core, and the inner core and the copper bundle wire core are stranded together. The tensile resistant strengthening inner core is an inner core made of a carbon fiber material or a galvanized stranded steel core. The special cable for the buggy ladle adopts the tensile resistant strengthening inner core, a four-layer high-temperature protective structure, a tensile resistant material, a high-temperature resistant material and a tear-friction resistant material. Due to a unique structure, reasonable materials and a scientific process, the tensile resistance, temperature resistance level and tear-friction resistance of the cable are greatly enhanced, the safety and stability of the operation of the cable are improved, the service life of the cable is prolonged, the working efficiency and the product quality are effectively improved, and energy resources are saved.

Description

technical field [0001] The invention relates to a cable, in particular to a special cable for a ladle car. Background technique [0002] At present, the widely used ladle car cables mainly use pure copper as the conductor, and natural + styrene-butadiene mixed rubber as the traditional process of insulation and sheath materials. my country is the largest iron and steel country in the world. The demand for ladle car cables is huge. The cable use environment is very special and harsh. It has to bear a lot of tension and the ambient temperature is extremely high. During use, molten steel splashes, steel slag bumps, and cable car stretching will occur at any time. , ground wear, and internal fractures, resulting in varying degrees of cable damage or even scrapping. Traditional cable conductors have a single structure and low tensile strength; insulation and sheath materials have poor mechanical properties, tear resistance, flex resistance, elasticity and processing properties; p...

Problems solved by technology

my country is the largest iron and steel country in the world. The demand for ladle car cables is huge. The environment in which the cables are used is very special and harsh. They have to bear a lot of tension and the ambient temperature is extremely high. Molten steel splashes, steel slag bumps, and cable car stretches may occur at any time during use. , ground wear, and internal fractures, resulting in varying degrees of cable damage or even scrapping

Traditional cable conductors have a single structure and low tensile strength; insulation and sheath materials have poor mechanical properties, tear resistance, flex resistance, elasticity and processing performance; poor oxygen and ozone resistance, easy to age and deteriorate; poor oil and solvent resistance , low acid and alkali corrosion resistance; low heat resistance, and is a flammable material

Therefore, generally it can only run for about three days. Once the problem of the cable is not solved in time, the molten steel cannot be transported to the designated location in time, and the molten steel and the ladle car will solidify together, which not only causes a great waste of resources, but also has very serious consequences. , huge economic loss
