A special cable for a tipping car

Abstract

The invention discloses a special cable for a tipper. The cable comprises a first cable section and a second cable section. The first cable section and the second cable section are connected togetherthrough external thread connecting rings; the surfaces of the ends, close to each other, of the first cable section and the second cable section are fixedly provided with the external thread connecting rings respectively; and the inner wall of each external thread connecting ring is provided with an internal thread matched with the external thread connecting ring. The cable has a flame-retardant filling layer made of a powdery fireproof material, so that when molten iron burns through an outer protection layer, the molten iron can be blocked and quickly guided to the ground, and the cable canbe effectively prevented from being damaged by the molten iron; and a heat insulation surface layer and a heat insulation filling layer arranged in the cable section can reduce the influence of high temperature outside the cable on cable cores inside the cable.

Description

technical field [0001] The invention relates to a cable, in particular to a special cable for a tipping vehicle. Background technique [0002] Most modern ironmaking uses blast furnace ironmaking, and some use direct reduction ironmaking method and electric furnace ironmaking method. Steelmaking mainly uses pig iron smelted in blast furnaces, sponge iron smelted by direct reduction ironmaking, and scrap steel as raw materials, which are smelted into steel by different methods. The basic production process is to smelt iron ore into pig iron in an iron-smelting furnace, then use pig iron as raw material to smelt steel by different methods, and then cast it into ingots or continuous casting slabs. [0003] The dumper is an important part of the slag removal system of the molten iron tank in the steelmaking plant. When the steel in the molten iron tank is poured into the furnace, the dumper dumps the molten iron in the molten iron tank into the furnace. Turn the hot metal pot ...

AI Technical Summary

Problems solved by technology

[0004] Among them, the working environment of the tipping car is carried out in a high temperature environment, which is easy to affect the service life of the cable of the tipping car, and when the molten iron in the dumping process is splashed on the cable, the high temperature of the molten iron will cause damage to the cable
